Shock symptoms and conditions

I just had a mirena put in on Thursday, after the recommendation of the obgyn (she said she had one).
When I was asking my questions I was concerned about the acne, since I never really had it in my life and the possible headaches. BUT reading the above postings is not very encouraging: low libido, weight gain, mood swings. I will surely be back to post the results after a month.
Note: I have not had children, but since I was prone to severe pain/length of periods that is how mirena was suggested.
INSERTION was excruciating! "3 small cramps" was in fact pain that left me quivering and in shock. Doctor's need to be more transparent about the insertion process (especially if you have not had kids).
I will be back after my 4 week check up with the latest report. (and if need be, I will be assertive in the removal demand.)
Thank you so much, ladies.

I have been taking 8 500 mg caps of pentasa a day for over seven years for what doctors told me was Crohn's Disease. I just found out that I don't have Crohn's Disease and I am in shock not to mention that I have lost over fifty pounds and in bad stomach and back pain. What is going on. I will add that the four day hospital stay has really hurt me emotionally, money wise and I am heart sick. Patricia

Okay, here is my story.
I went on Ovcon when I was 19 (in 2000 I think) and took it nonstop for about 8 years. I finally went off of it this past April 2009. When I first started I did get all the normal side effects (5 pound weight gain, breast tenderness, etc) but after 3 mos it resolved. When they switched to Balziva I noticed those same mild symptoms that also resolved. I finally made the decision to go off of it when I broke up with my boyfriend, since I had been wanting to for a long time. I noticed over the last 4 years my hair had been getting progressively thinner and thinner. I can't believe how much thinner my hair looks now compared to when I started, looking at pictures from when I started was always a shock. I know there is no real evidence for this but BC has been loosely connected with gum recession, ligament laxity, etc which I have also been experiencing. Don't know if that can be attributed to BC or not, but it just contributed to my concerns with being on the pill for so long. After 8 years, I barely got a period, it was more like a day or two of clumpy brown crap, I'm sorry I know that is gross, or no period at all. Honestly the period part of it was a plus since it is never fun to be on your period.
So, I was very worried about what would happen, especially with my hair when I stopped taking the pill. Let me tell ya, it wasn't pretty. Starting a few weeks after I finished my last pack of Balziva, (I didn't stop mid pack in order to keep things as normal as possible) my hair started falling out in handfuls in the shower. I actually sat and counted 300 hairs in the hair catcher after one shower. This went on for about two months. I bought Nioxin #1, and it didn't make much difference with the amount of hair falling out. I told myself I would not seek medical advice until my periods regulated again. In my mind this would mean I was back to normal and on a normal hormone cycle. Yikes my hair got thin, but with the Nioxin, did start to grow back. It took about 4 months to get my normal period back, or what I think is a normal period, its been so long since I had one. I was happy about this because my nurse practitioner said it could take up to a year to get your period back. I'm not completely regular now (September) but it seems to be approximately every 5 weeks. But it wasn't really regular before I went on the pill if I remember correctly. Anyway, even though my hair still looks very thin, I am noticing short, growing hairs all over my head. Which is such a relief! I really didn't want to have to go on any more synthetic hormones to take care of my hair problem. I will probably get my hair cut short so it doesn't look so bad till the new hairs grown in. The Nioxin I bought ran out about a month and a half ago and I am back on normal (cheaper) shampoo and the hair that falls out is much less. Although I do still notice my hair all over the place, its not as extreme as it was. We shall see if it ever gets back to pre birth control thickness again. Just a note, I did use the three step Nioxin package, cleanser, conditioner and the spray that is supposed to stimulate hair growth. But again I only bought it once to give me a boost.
Hopefully this is informative for anyone worried about going off the pill. I just really wanted to be all natural again. And condoms aren't so bad :) once you get used to them.
Oh and I have been trying to maintain a healthy diet including lots of greens like kale and spinach, less meat, and lots of fruits and veggies!

I had my first Mirena five years ago. I loved that I had no periods... it was wonderful! I just had my second one placed two weeks ago and I have been getting flushed, have panic attacks, and a weird "shock-like" feeling in my vagina. The panic attacks are driving me crazy and I wasn't sure if it could be related. After reading several postings, I realize it could very well be the Mirena. But why don't I remember this with the first one? I did get the "shock-like" sensation before.

I am a 40 year old female. I found out 3 years ago that I have factor V. I've been hospitalized for 17 PE's. I was being treated with coumadin, plavix, lovenox. My INR will not stabilize. The doctor has now put me on 30mg. of warfarin a day. and my INR still sets at 1.2. My side effects are awful. I feel tired, week, cold, weight gain, but most of all the terrible headaches. The doctor says it has nothing to do with the warfarin. I stay depressed and now losing hair. I've taken my doctors advice and I'm going back to the cancer center where they are more experienced. I feel like I'm dying everyday and its not in my head. I do believe its side effects. And if its not moving my INR than to me it seems useless to take such a high dosage. Its a catch 22.

I had my Mirena placed in the first of may, it was very very very painful. The following months I had spotting and bleeding EVERY day, I had no energy what so ever. Some days I even felt pregnant, and not to mention my face, I looked like a teenager again, horrible acne!

Then I started having this tingling and stinging sensation in my hands and feet, I googled it and all I could find was MS(multiple sclerosis)! In shock I did a search in English(I'm from Norway) and found that I was NOT the only one having MS symptoms with the Mirena! I had the Mirena removed this week, but I still have the symptoms, but I guess it takes a little time for the hormones to leave the body completely!! My boyfriend said to me "let`s hope you didn't get MS from the Mirena".. And I am of course terrified... I have an appointment with the doctor at the end of the week!

I just don't think that this is a coincident!

I take lithium, 1350mg/day, for 5 years now, and about 2 years ago I started getting tremors but worse in my left hand, so it was actually painful and for a while the doctor thought it was carpal tunnel but it turned out not to be and he didnt know what caused it-now ever since then my left hand has gotten worse & typing with it is a little problematic, its like the nerves are messed up in that hand, it won't always hit the right numbers. Its starting to freak me out a little, but in the last year I've started having episodes where my entire left side goes tingly like its asleep, my vision blurs, I get shaky all over and have such rapid heart palpitations it feels like my entire body is in shock. This lasts for about half an hour usually, has landed me in the ER twice, & they claimed each time not to know what caused it and looked at me like I was making it up, and didn't give me anything for it. I also get the typical symptoms- mild hair loss, memory loss, speech impairment, weight gain (I was 120 now I'm 160- luckily it distributed so its not too obvious), & it does not stop depressive episodes, just shortens them, and I still get anger episodes fairly often, usually as a split second reaction to something very small. I'm definitely looking into getting off of this as it is worrying me, more about the episodes and my left arm/hand issues than anything else, especially that now I have trouble with coordination in my left hand,which sucks because my desk jobs always involve a LOT of typing.

I've had Mirena for almost a year and I'm wondering if there is anyone who's suffered adverse effects that didn't start until much later. I had the usual severe cramping and excessive bleeding for a few months after I got it, but my period has been pretty regular since then. I do have sharp stabbing pains (I'm guessing they're cramps) off and on. Very occasionally they are just terrible, but normally it's just like a quick shock every now and then. I can tell that there are extra hormones being put into my body because I have experienced all the stereotypical period side-effects (moodiness, cramping, cravings) much more than I ever did before I got Mirena. About two months ago I was sure I was pregnant - I had all the symptoms - but three pregnancy tests all came out negative. I'm not experiencing anything bad enough to get it out. So far it has actually been great. I feel terrible for everyone suffering all these severe side-effects. I guess I'm just wondering if these symptoms show up sooner or if they can start a year or more after Mirena has been in. Please let me know if there's anything I should be watching for. Thanks.

I've been on birth control since my early 20's and now I'm 39. My most current bc was Diane 35 which was not bad. I was scared about the risks of using birth control after the age of 35 so changed to a lower form of birth control-Aviane. Was suppose to have Alesse but was given the generic Aviane. I've gained weight so most likely due to my bad habits, old age due to a lower metabolism. I'm sure I'm at my max weight of 120. I've been feeling horrible in the dressing rooms when I'm trying on clothes and my stomach seems to be more "muffin top" than normal. Also, feel very bloated all the time...thus, a spa rep had asked me how many months I was(might have been the type of top I was wearing but...) I just went on the scale at a gymn I was trying out and to my shock I had gained 10 pounds? I haven't eaten that much different lately...is it Aviane? I think it's time for me to get off bc..

My local hospital prescribed Avelox for a sinus infection since Amoxicillin wasn't working. My fever jumped up to 102 the first 2 days so I called my family doctor. He told me to keep taking the meds for 2 more days and if my fever persisted to call him back. I experienced the high fever on day 3 and then was in a world of shock when I took the 4th pill. My body went numb, I was speaking but had no idea what I was saying, dizzy, the fever subsided during the day but spiked back up to 102 that night and I was very irritable. I made a doctors appointment the next day and the doctor told me to take the meds at night and I wouldn't have those reactions. After reading these comments and my day 4 episode, I had it in my head that I was not going to take any more pills. Then I called a nurse friend who assured me that it wasn't the antibiotic making me feel that way.....it was the extra strength Tylenol. She advised me to take the pill. I took the pill and not two hours later, my body went numb, I became dizzy, my tendons in my right knee and left foot swelled and I couldn't sleep. After my body went numb, I took the rest of the pills and flushed them down the toilet. I'm still feeling the affects of the pills and it's been 2 days. I've been swallowing gallons of water to flush it out of my system. I lost an entire week of work and pretty much my normal life. I'd much rather have sinus pressure in my head then deal with these side effects.

Have had the Mirena for a year due to needing some hormone therapy during menopause.I am 54yrs old and had my last period over 2 yrs ago-look physically like I am in my 30's. Had a breast reduction and weight reduction surgery over 10yrs ago VERY successfully lost 10# off my chest and 168# off of my body. SINCE having the Mirena I have gained over 30# and gained 2 cup sizes in my breasts! HELP!!! I have been treated by my regular doctor for mood swings with WellbutrinSR, Lexapro, Lamictal, Topamax and others-nothing has worked more than to ease some of the edge. I have gone from a size 2 to a size 10-12 in 9 months and am desperate for an answer! I feel as if all of the previous progress I had made with the weight reduction and breast reduction is all being undermined! I had a tummy tuck last September 08 and I swear my stomach was flatter before I had the surgery! I look pregnant! The surgeons have done a CT scan and can find nothing to indicate the surgery went bad. I don't know what to do as my OB-GYN tells me that "this IUD" is my best bet for hormone therapy and that it is ABSOLUTELY NOT the cause for the weight gain or breasts. Has anyone else "my age/menopausal" experienced this? Most of what I have read has been very helpful BUT all but a few are pre-menopausal and way younger. PLEASE let me know your thoughts!!

Glad I stumbled on this website. I started NR in April. All seemed well. I spotted most of the 1st month pretty heavily but that's not unusual for me starting BC. A number of vague symptoms began creeping up on me and I decided to stop it last week to see if it could be related to NR since many of the symptoms appeared or worsened after starting it. Sudden hot flashes that lead to panic attacks, feeling like I was as close to fainting you can get without hitting the floor. At first that was once a month but then became more frequent until lately it's been everyday! No fun to say the least! vision changes, waves of severe nausea and dizziness in the past week...I've had it. And it's even been out for a week. I hope the effects wear off ASAP. appreciate all the comments on this forum. makes me feel less alone

I went to the doctor one day they told me that nothing was wrong with me and that is was just in my head needless to say i had not urine for a day and my back was killing me so we i got home i went to the ER and they told me that i had a really bad kidney infection and bladder infection and a UTI ya it hurt like you no what. they gave me sulfamethoxazole to take for 14 days well in the first week i felt funny and i didn't seem like something was wrong with me So a week into the medicine i was a work and the inside of my mouth started peeling yes peeling like the top layer was coming off and i started feel really funny so i called the doctor and they said everything was ok that it was a normal reaction to the drug not being a nurse or doctor i believe them so in middle of the night my face was swollen i had a rash on my face and my chest. I immedity went to the doctor ( a different doctor of course) he looked at me and said what have you being taking i pulled out the medication out of my pocketbook and he look at me in shock and said i know you have not being taken this you you are highly allergic to the medication ya i said the same thing i had no clue but he gave me a shot of something and gave me prednisone i not feeling that will he said it would take a couple of days to kick in but hey i need something now!!!!

well im a 19 year old female. i know that sounds crazy but i have really high blood pressure.usually 140/90 they think its due to the small left kidney thy tried me on different kinds..but my feet ad face would swell. they told me they wanted to stick me other best out there..but didn't want to stick me on it without being on birth control.. ad just turned 18 at the time and didn't want to be on it yet.soo they stuck me on ic atenolol. they started out at 25 mg . the dosage ended up going ay up to 150. it is the highest te medicine goes. so i decided to go on birth control to try this pill that would apparently be the most effective.thinking that i would just go n this new pill i went in to change medication... they had me stay on the 150 of ic atenolol plus 5 mg of ic lisinopril. then they raised it up to 10mg of the lisinopril. i had a problem with forgetting t take it. but these past 2 months i ave remembered everyday. so when i started getting chest pains and pains in my arms that felt like i ha just gotten a shot by huge needle. i though maybe it was because ijuss started retaking it... ut its been over a month and ive gained 10pounds..have been nauseated, dizzy,loss of energy, and the pains in my arms and i didn't sleep at all last night because of te tightness in y chest.i was scared to death that if i went to sleep i would have a heart attack in my sleep or something. ad then whil laying there. i jumped because i felt shock in my lower back.. i thought was going crazy so i got online to look up side effects and came across this. and now im calling my doctor to get taken off the ic lisinopril..and now maybe the atenolol to because i am afraid of blood pressure medication

I had to take Prednisone as pre-medication before a CT angiogram (had an allergic reaction to the dye in a previous exam). Dose was 50mg, 3x, 6 hrs apart. About an hour and a half after the first dose, I was feeling rather "out of it" and unwell. Took my BP out of curiosity: 145/104! It dropped later, but after the 2nd and 3rd dose (all this in a twelve hour period), both heart rate and BP stayed elevated (hit 128/minute pulse, beat my old record when I was hyperthyroid on Synthroid!)

It's hard to believe this doesn't have a deleterious effect on the body--for me, it was of course preferable to the risk of anaphylactic shock. But I really feel for all of you who have to take it for an extended period (and sure hope I never do). Maybe it helps at least to know your symptoms and actions are definitely a product of this drug and that you will feel better when you can stop taking it?

I am so happy I came across this site! I have been experiencing all these symptoms as well. I am 22 years old and I have been on the ring about a year. I have noticed that I gained weight in the past year, but just attributed it to getting older. I have always been a petite woman, and so are all the women in my family, so the 8 pound weight gain in the first couple months was a huge shock. I have tried working out, and eating right, but the weight always comes back and my cravings are unlike anything I have ever experienced. I have also noticed extreme irritability and I seem to cry a lot more than I used to, over simple, stupid things. I am in the best relationship I have ever, I have a great job and school is going great, but I seem to get extremely sad and irritated sometimes, especially the week before I take it out and the week after I put it in. I have never been like this crazy, emotional person I seem to be now. I also seem to have no energy and being active is at times a lot harder than it should be, especially for me, as an active, on the go type of person. I also have noticed my leg is always numb, my doctor recommended a massage therapist, which helped, but it always comes back. After reading symptoms of leg pains, due to blood clots, I am even more skeptical.
I have read up on side effects on other websites, but like other readers, it says some women experience these signs. Maybe a lot of women are like me, and have never posted anything. I have not put the ring back in after my last period and I am not going to. I dread it every time I put it in, but until now I thought it was just in my head. I am not getting back on the ring, lets see if I can get rid of these horrible, hormonal symptoms.

I'm only 18 and I've been using nuvaring off and on for a while.
I took it out the first time because it was making me gain weight, decrease in sex drive, anxiety attacks, painful sex and i had been crying for no reason. I feel so bad for my boyfriend because I'm just now realizing that my lack of sex drive and painful sex is most likely related to the nuvaring. We've both been confused for so long and he's been feeling so bad about himself thinking its his fault :(.

This is the 2nd week I've had it in since the first time i took it out months ago and I've gotten what seems to be a yeast infection...but like someone mentioned earlier, my yeast infection tests come back negative...as do std and sti tests.
This is my second time with yeast infection symptoms and im only 18...
so, already that seems a little fishy (no pun intended).
Ive also been tested twice for all stds and sti's both times negative.

My doctor and mother don't believe any of this has anything to do with the nuvaring and tell me that i shouldn't believe what i read on the internet because most of what im reading is "rare"..but i believe it and i believe its happening to me.

im taking it out right now.
This website has been very helpful!

I've had my thyroid removed in 2006 and since then I've been on medication, i was ok first and i thought i was ok until now. i had leg pains that woke me up from my sleep and i went to doctor and couldn't figure out why i was having this pain, i thought i had restless leg syndrome or sciatic but doctor said no. now i'm reading all your side effects and I'm in shock, i had no idea that it can cause to leg pain. also I've change my medication to generic (because of insurance issues) since then i guess my itching started. i thought i had allergic reaction to food or bugs or something and i went to allergist of course nothing came out. now I'm reading the side effects of this medication, it can cause hives, rashes, itching and even urticaria which i have right now. i went crazy to find anything in my house to find a bed bug, spider, flea or anything that can make me itch like this. the other side effects that I'm having are hair loss, red/hot face. i can not believe all these symptoms are actually side effects to a medication supposed to make me feel better. whoever says that's they find it weird that this medication has this many side effects, we are not crazy. this effects are real and so many of us has them.

I was given Levaquin on February 14, 2001 for a sinus infection. I had taken a Claritin ready tab before I took the Levaquin. Within 5 minutes of taking Levaquin, I literally felt as if ants were crawling all over the inside of my skin. I was in the bathroom when this happened and I remember that I started to sneeze non-stop. It got to the point that every time I sneezed, I could feel my throat closing and blood would come out of my nose. I knew I was in trouble. I didn't have time to wait for an ambulance and my mom, who has epilepsy and doesn't drive went with me to the ER. By the time I got there, 5 min drive away from my house, I was covered in huge hives. My hands, feet and face were also blue and I couldn't speak! I had gotten there just in time. I got 3 shots of antihistamine (benadryl) and 3 of hydro cortisone. My doctor was in disbelief when I went to see him the next day to tell him what had happened. Apparently my reaction was "rare", but by the other stories on this page-I don't think it is. It was a horrible experience going into Anaphylaxis shock. I now watch everything that is an RX and ask a lot of questions. I found out a few years later that I was also allergic to sulfa based drugs, almost the same reaction (not as severe) but I was ready and I knew what to do. Thank God for Benadryl!!!

My healthy, active 55 yr old husband of 30 yrs was prescribed SIMVASTATIN in Aug. of last year. He started having pains in his legs & back and had an appointment in Oct. with the dr. to check on how he was doing with the new drug. When he went in to the office, he was having terrible pains in his chest, legs & back. The dr. immediately called 911 thinking he was having a heart attack. He was in the hospital for a week while they ran a multitude of tests. All came back clear for his heart. He kept telling the dr. that the back & leg pains were still there. They didn't seem to be concerned about anything except his heart. He was dismissed continuing to have pain. The pain steadly increased over his whole body, then in Feb. of this year, he suffered a major seizure and spent another week in the hospital. This time they wrote it off as epilepsy and put him on anti-seziure pills. After he was released, the symptoms increased, his memory, vision & balance are all effected, he has chest pains, depression, and is in constant pain. He's been sent for numerous MRI's, bone scans, blood tests,etc. He has been to neurologists, neurosurgeons, chiropractors, physical therapists, etc. The entire time, his health has declined because he was being poisoned by Simvastatin. Finally, after doing our own research, we found a neurologist that recognized the problem. He told us that this drug distroys muscle tissue and that the damage may be irreversible. My husband can no longer work, drive, or enjoy life. He walks without a cane or walker, and depends on pain pills because the pain is so severe. He stays in bed most of the time due to the pain and lack of energy. He has been off Simvastatin for a week now with no change. We are hoping & praying for improvement over time. PLEASE, if you are your loved one are taking this drug-STOP IMMEDIATELY. The results can be devastating. I can't imagine why the FDA would approve a drug like this that destroys quality of life.

I'm fed up. About 4 years ago I had a complete thyroidectomy and OMG my life has been a mess ever since, Yes, I needed the gland removed (it was a goiter pressing on my air way and esophagus), it needed to come out but OMG what a nightmare. Synthroid is a drug I can't figure out. I am convinced that this has ruined my life. I have developed chronic/non-stop head pain and pressure. My B.P. has gone up and now I'm on B.P. medicine. (still have severe head pain). It just never leaves me. E.R. visits/hospital stays and on and on. They treat me like I'm a complete lunatic because they can't seem to find anything organically wrong with me. Ummm-it hurts(my head). I am starting with a new Doctor who is a D.O. rather than an M.D. and I am praying that he finds what the **** is causing my pain. I feel like crap. The T.S.H. is in normal range but I have learned that the T.S.H. is not everything (even though my thyroid is gone). The isiots for lack od better description, are just too lazy to go the extra minute to find out what is wrong here. I just want to be able to function and this head pain will not let me do that. It is a nightmare and I have nothing but sympathy and empathy for anyone who suffers with pain on a daily basis.

The only constant is the Synthroid. Maybe I can't take this stuff. It has to be that my body just can't tolerate it and need something else or T3 added (I don't know). I just pray that this new doc can figure it out because I feel so helpless with this. My pain is always there squeezing and pressing. It is horrible. Maybe Synthroid is the culprit. Good luck to everyone.

I was prescribed levaquin back in May for a sinus infection. Have suffered from severe side effects, worst of which being joint and muscle pain, stomach pains, weakness and hives (last dose was taken 10 days ago). This has been the most physical discomfort and pain that I've ever been in. In addition, my ability to concentrate and recall easy things has lessened.
The "Bafoon" of a doctor that prescribed this claimed he didn't know what was wrong with me after a normal blood test. My new knowledgeable doctor told me that some people can't even walk after taking Levaquin. She says it takes on average 7 days to 6 weeks to feel improvement. Being a 36 yr old woman, having to move turtle speed, and feeling like I'm in a 90 year old body is very depressing.
If anyone has any information on any class action or mass tort litigation lawsuits please send me the information. This drug is poison and should not be prescribed for minor infections!!!

I am 39 years old and very active. I have been on Singulair for about 2 years now. I did not think I had any problems while on the medication because it did help my breathing. I am now on an antidepressant (Lexapro)which I began about a year after I began the singulair. My depression however started almost a year before I actually got on the Lexapro. I had alot going on in my life so I just equated my depression to that. However I am realizing now that maybe the singulair triggered my depression. I ran out of singulair two days ago and am experiencing withdrawal symptoms, extreme tiredness, stuffy head, and I had heart palpitations last night, which I have never had. The withdrawal symptoms are why I began researching the medication because I couldn't understand how being off of it for such a short time could cause such an effect. I was on Singulair once before about 6 years ago before I retired from the military while I was at Ft Hood before I deployed to Iraq. By the time I left Iraq I was on multiple medications, Singulair, Claritin, Advair, Emergency Inhaler, When I arrived in Iraq I became ill and listed my medications. They were in shock and took me off everything except Claritin and I was fine. It wasn't until I returned home I began the Singulair again. (Why? I guess I never equated it to causing my other issues until now), I am also taking Zyzal and Lexapro. I see now that every time I take the Singulair it leads to additional medications to other things. I am going to stay off of it and hopefully be able to wean myself off of the Lexapro as a result. Unfortunately I probably will still need to take an allergy medicine. Thanks everyone for posting this useful information. I have two kids 6yrs and 12yrs and I know now that they will never take this medication. They have allergies like me so it is very probable that eventually it would have been mentioned. The allergist/asthma doctor is adamant the 12 year old has asthma but I never gave him the advair that he wanted him to take because I did have side effects from that medication that I did recognize myself and my son is the fastest runner on his select soccer team and extremely athletic without it, no emergency inhaler needed or anything.

I am in shock and so glad that I came to this website. I have been taking simvastatin for about 5 months now and this morning I decided to do a web search with the words simvastatin and headaches. Everyday I for the last two months I have been asking myself why am I having these terrible headache. My Doctor did a CT scan, I had my eyes tested, I had my hearing tested, my blood tested and everything comes back good. I realized that I have to do something about this problem myself because my doctor prescribed another pill for the headache and that's that. Today I did not take the medication and I will not be taking it again. The symptoms that everyone described are so real to me but the headaches were the worst. I have to thank you all for posting this information. I now feel that I will get my life back.
Thanks verdul1

Last Tuesday, my son was prescribed Singulair by our pediatrician. He was also prescribed Pulmicort by nebulizer at the same time. Within a couple of days, I was noticing a dramatic change in his personality. He's only 21 months old and normally a very happy, lovable, easygoing little boy. He did a complete 360. By Friday, I had to take a day off from work, as I was too scared to send him to daycare. He took his last Singulair chewable tablet on Friday night. Saturday was his worst day by far. I was in shock by his behavior. He was extremely aggressive, punching and slapping anyone who came near him, he was throwing things, throwing himself into walls, etc, just completely out of control. I contemplated even taking him to the hospital, but then started doing some research online. I had my mother contact a pharmacist whom we trust, who advised for us to stop the Singulair, as if he was having any side effect, it would more than likely be from that. On Sunday, I started to see some changes in him. Yesterday he was getting back to normal. Today, he's that much better. We actually went back to the pediatrician this morning and I'm actually thinking of filing a formal complaint against the dr. as he basically swore up and down that his side effects weren't from the Singulair. Well as a parent, does anyone really think I'd want to put my child thru this?? It may be different if he had behavioral issues prior to this, but this came completely from left field. I am beyond upset right now, pissed off that this drug can be on the market. How many children have to be affected??? This is very scary to me. My son was only on Singulair 4 days, and I feel guilty and angry that he had to go through even that short period of time on the drug. And then to have a pediatrician basically discount me and say that it has nothing to do with singulair is a complete slap in the face! I won't stop speaking out against this drug and hopefully it will inform other parents of these harmful consequences!!!!
