Rages symptoms and conditions

My husband has been on Simvastatin for a few years, six months ago his dose was increased to 40mg, since then he has become someone I don't recognize, we have been married over twenty years and he used to be a very placid and wonderful man. He is now both verbally and physically abusive, he threatens me with divorce on a regular basis. He lies about me to others telling them he does all the housework (never) there is never any food in the house ( Totally untrue) He disappears for hours on end, and sleeps much of the time. He can be quite plausible with other people but turns into a monster when he returns home. Doctor told me I don't think it can be the statin, don't believe everything you read on the internet! She said to be sure for him to come off it for a few weeks - he refused! His aggression is escalating and I now dread him coming home. he has odd moments of being nice but within hours he is back to being nasty. He had been impotent for 7 years but now during his "nice moments" becomes amorous! I am at my wits end, has anyone else experienced this!

my boyfriend has been on prednisone for 4 years and he is terribly snappy and aggravated all the time and short tempered and does not think that he is... i love him so i deal with it but its getting harder because he dosnt feel this is correct every time i ask him something he bites my head off and almost everything i do irritates him gets on his nerves the mood swings are out of this world sometimes and he totally thinks im being a lala in his words...will someone respond to this so i can show him and he will know im not just saying these things
all this

Thank You!!! I'm not the only one! I had the Mirena inserted in 2005,removed in Sept 2008. Painful cramping immediately that continued at odd times throughout time I had it. Bleeding for the first 4 months. Back Pain followed and landed me in the ER. At the ER I was told that I had blood in my urine. Antibiotics had no effect. Back pain continues today but is markedly less. Major mood swings leading to depression. Took Zolft at increasing doses with no effect. Never been prone to any of these before. Rages would come on over the littlest things. Extreme anxiety attacks leading into panic that left me completely irrational. Almost lost my husband and kids due to mood swings. Joint pain came then in my lower back and shoulders and wrists. Saw doctor, no reason ever found. Lumps showed up in my breasts that would swell and receed with my monthly cycle. Extreme sensitivity during sex with bleeding and cramping after. Cysts on my face and large acne bumps on my back that were so painful to the touch i could not even wear a bra. These spots took weeks to go away. Headaches that left me sick and weak on the couch seeing spots. Dr's insisted these symptoms were not related to my birth control.I had tons of fatigue but chalked that up to the depression. I also started having a lot of trouble with dryness in all of my mucus membranes. Even my eyes hurt. Over and over saw many dr's never could find what was wrong. This birth control nearly ruined my life and cost me three important years with my kids that i should have been at the top of my game. I have girlfriends who have received the mirena with almost exactly the same progression as me. I feel deceived by the listings in the information pamplets I received. I expected bleeding and slighter periods but never did they list these symptoms. I even looked at their website before I received it and they are not listed there either. I even had an argument with my gyno about having it removed because he knew of none of these side effects. I have seen a significant change since the removal. Mood swings down, energy back up. Kids say I'm like a whole new mom. To those ladies interested..contact K. in Texas to find out information about a class action law suit being filed.****** Don't let anyone else be hurt by this product. Who knows how long this is going to negatively affect our bodies?

My daughter had been on singulair from the time she was 8 yrs old until she was 14. This will sound as if I am a horrible mother but I just thought that she was a raging bitch. Without my knowledge, she stopped taking her Singulair for a few months and she became a different person. She was so sweet and loving. One night she came in my room having an asthma attack and I asked her if she was taking her meds, she admitted that she had stopped taking her singulair and I got on to her and immediately got her prescription refilled. Within a few days of taking the singulair she turned into a raging, screaming emotional wreck, a TOTALLY different person. I feel so bad that for 6 years of her life I put her on medicine that caused her to have screaming, uncontrollable tantrums, and severe mood swings that caused her to be miserable. It does seem to be the only thing that effectively controls her asthma symptoms but the emotional havoc that is causes her and the people around her is not worth the benefits. We have an appt. with her doctor to see what other options we have.

hi all. thanks for writing your comments here. it has helped me today, another HORRIBLE day of prednisone hell. i have been seriously ill for 8 months been told ever other week I'm likely going to die from lung disease (i'm 35) and after a painful lung biopsy have been told my lung problems are almost all reversible... after a year on high dose prednisone. i was on 40mg a day for a month a while back and was so out of control from rage and crying and insomnia and panic/suicidality, ravenous appetite, that they lowered me to 30. then after biopsy they said i should be on 100mg to cure me, we settled at 60mg. it's been 24 days. The moon face started about one week in. i've gained 8 lbs. i am an emotional wreck. i have at least one rage filled attack per day where i am screaming and want to kill somebody or destroy something. some days i am so filled with hopelessness and worry i just want to die. my body changes (after just losing 30 lbs and being a work out fanatic my shortness of breath makes it impossible to walk up 2 flights of stairs without resting) face changes, acne, excess body hair (oh my god please make it stop i'm like a chia pet and i'm so afraid it is going to get worse) double chin, puffy eyes and cheeks, absolutely uncontrollable emotions and mood swings, inability to be logical or reasonable. i don't want to leave the house, i'm panicked and scared all the time. i never sleep. ambian gives me minimal relief (just started taking it) i feel like i'm losing everything, except my lung functioning is returning and i'm not going to die from this illness (they assure me THIS week) i understand light at the end of the tunnel, but living like this is unbearable most days, almost impossible the rest of the time. am i alone with the severity of this? or are all the others like me too busy hiding the sharps and crying in a corner to write on this board? thanks for listening :)

figures, forgot to mention what HELPS. no eating after 8 (7pm is better) no salt, no sugar, exercise, even just a walk every day, anything physical, i walk like a grandma on the treadmill but i still do it, sometimes it is the only thing that stops my crying. no alcohol, support and understanding from loved ones, it's not you, its the drugs. good luck.

My 7 year old son has been on and off singulair for a couple of years. He has been on it again for a month and we have noticed very aggressive behavior. He gets angry easily, nasty and into these rages where he actually is hitting me and slamming doors (even breaking the jam on his bedroom door!), just because he is not allowed to do something! After finding this site, I called the doctor(who of course did not call back yet) and took him off of the singulair. I am hoping the behavior gets better!

Since having the mirena, I have lost my sense of humor, my sex drive, I get into hideous rages, I feel like I have something crawling under my skin when I have PMT. The PMT hardly ever goes away and as a result my breasts are twice the size they usually are, I have got stretch marks, they seem to swell for three weeks out of four and then I have a small period, when I finish bleeding my breasts swell again as if getting ready for another period. I suffer from headaches, tearfulness, slow witidness (used to laugh a lot). My boyfriend and I used to enjoy a good sex life, now I can't stand him touching me, so if I don't get the mirena out, I will be back on the shelf again, but I don't want a baby, can't take the pill that has an awful affect and the other copper coil made me bleed for two weeks at a time. What is a gal to do? Think I'll pull it out myself I feel that furious with having this alien inside of me. Plus I go running lots and do circuits at the gymn and am up a dress size since the mirena doh! Am sick!

PRAISE GOD for all of the stories shared on this site. And I've only read page one. My husband called me back today to say that he "googled" Singulair and found some interesting things (to say the least). While we were on the phone, my three-year-old was in the throes of another meltdown, kicking me, hitting me, throwing whatever he could get his hands on. My older two boys, 8 and 12, were ordered, once again, to lock themselves in their rooms to avoid being hurt by him. He will throw stuff, bite, hit, kick, and, at times, spit on us. This disturbing behavior is rather constant lately. He is like a mad man. Very scary.

Caleb has been on Singulair since about age 1, when he was diagnosed with chronic sinusitis and allergic rhinitis. Unfortunately, we initially equated his rages with the onset of "terrible two's" and dismissed his behavior to a chorus of "oh, he's just a boy!" My husband felt, at times, that I was just not disciplining him properly. I intuitively knew, having raised two other boys, that this behavior was abnormal, even for severe tantrums. We received a variety of suggestions from his pediatrician, caregivers, and grandparents, all to no avail. We have several calm days but things always deteriorate back to insanity. He is VERY unpredictable.

Last Thanksgiving, Caleb (age 3) was kicked out of his daycare setting for biting and hitting. Once I witnessed him run as fast as he could into a group of playing children, falling on them, kicking them. He would walk up to sweet little girls half his size and push them down as hard as he could. It was a nightmare. My husband had to take 3 weeks of leave to stay home with him while we prayed and searched for new care. We had him evaluated and he was staffed into the "developmentally delayed" program in our school district (for poor adaptive skills and personal/social behaviors). We recently had his tonsils removed, hoping that some of the sinusitis symptoms and behaviors would improve. They really haven't. This past week we have been looking into the Feingold diet. We have been PRAYING for answers. The last time we spoke with his developmental neurologist, he recommended a trial of Risperdol (sp?). We feel like more meds would be like a band-aid, not a solution. But his rage is becoming unbearable.

So, that brings us to today. I was so moved by your accounts. Unlike so many of you, we don't have much of a "before" to go by. But his "after" sounds VERY much like what you have all described. It's probably the pure rage that I see on his face that is the scariest part. And at the same time he seems desperate and vulnerable. He truly seems to snap. If we had pool chairs, I can just picture him throwing them (citing another post :).

We are going to throw the Singulair away. He will never, ever have it again. Even if this isn't the cause of his problems, I certainly don't want to exacerbate any behaviors with this toxic medicine. I will post again just to let anyone who's interested know if this changes his behavior. I am praying that my entry will help someone else, just as all the other postings have helped me. I have renewed hope.

I have copied many of your comments to a Word document. I will be sharing it with a high ranking officer at the medical clinic/hospital on Keesler Air Force Base. I hope that he will discuss this with his staff and that perhaps we can at least make a difference here. I, too, will be filing a report with the FDA. I can only pray that this medicine has not permanently altered his developing brain.

I'm glad my friend sent this link to me. My son was diagnosed with asthma almost two years ago. He was put on Singular and albuterol inhalers. He stayed with that for about a year. We didn't at the time have any health coverage and could no longer afford the Singular. We started giving him Zyrtec about three months ago. My son, he's 7, started going into these rages about this time last year and we had no clue as to why. We chalked it up to his age and being a boy. The raging has now stopped but he's still combative and lashes out easily physically. He's never been one to act violently before he was diagnosed with asthma. I'm now wondering if this is due to the medicine. After reading these posts we'll be taking him off the Zyrtec and trying something new.

Hi. I went on Lamictal April 2007 after being diagnosed w/ BiPolar. The key issue that brought me to the psychiatrist to begin with was acute depression following a divorce, move cross country, losing my job and my only son going off to college. All the big stress factors - short of death in family. Nonetheless, I was nervous that one year after all these crises that I was, if anything, feeling worse. I had been able to handle all the changes during them, but now that they were over all I wanted to do was sleep all day.... Anyway, I had been on Paxil for years re anxiety, and my psychiatrist decided to keep my on the Paxil till I tolerated the Lamictal, then get me off the Paxil..... Well, the 20 mg of Paxil and the 100 mg of Lamictal worked great, I thought; the Lamictal really raised the bottom.... BUT, apparently Paxil fuels mania, so after a few months, I was taken off the Paxil completely and my Lamictal went up to 200 mg. Almost IMMEDIATELY upon going to 200 mg Lamictal my ankles / feet / legs got enormously swollen. Plus, I noticed that my hair started to fall out // thin out.... Plus -- and I don't know if this is the Lamictal or the absence of the Paxil, but I sob uncontrollably almost 24/7. The sobbing and anxiety and sense of dread and sadnessness has persisted even when the Lamictal was dropped to 100 mg and the shrink added first Clonazepam .5 mg, then when that wasn't calming me, changed me to 1mg Xanax -- each as needed. The Xanax isn't helping me either, and now I also feel paranoid. So, in short: Lamictal at 200 mg makes my feet / ankles / legs swell or suffer edema; Lamcital as low as 100 mg makes my hair thin out; and either the Lamictal or the loss of the Paxil or these anti-anxieity meds (Clonazepam or Xanax) are making me paranoid, profoundly sad and depressed, panicked, anxious, stressed out and, most urgently, make me sob uncontrollably 24/7... My shrink says that we should use anti-depressants with bipolar, and that Paxil fuels the mania, but I tell you, I'd rather be manic and screaming at everyone than so depressed that I'm fearful and sobbing constantly.... Any answers out there: Any anti-depressants for your bipolar?

my son has been on it now for about 4 months and has tried to commit suicide in the process of a 5 week change from keppra to the lamictal.then had to take dilantin until reached full dose of the lamictal which for him is 150mgs 2 xs a day at first the keppra made him fly in to rages so that was blamed for the suicide attempt.but just a few days ago he said that he was having weird feelings again. so i don't know what to do. waiting to hear back from the dr.i would just like to know if anyone else has experienced such severe thoughts from taking this med or if passably it could be not a high enough dose.i don't really know anymore by the way my son is only 15 and he is on the lamictal for seizures.any feedback would be greatly appreciated.

I am a mother of four children (21, 19, 15 and 15) who have varying degrees of asthma and allergy. All of them have some degree of ADHD as well. The oldest took Singulair from grades 7 to 12. It was great for his allergy, but he had a depression which was attributed to his ADHD.

The second is still taking Singulair. She is highly asthmatic and it has been beneficial for her. The severity of her asthma went down to the controllable range, and her migraines (suffered since second grade) significantly decreased (documented side effect).

The last two, identical twins, began taking Singulair four years ago when they developed asthma as they entered puberty. They became oppositional, defiant, prone to rages, and curiously not hustling hard enough at their sports. Prior to this, they were solid, dependable students, with moments of inspiration - and aggressive athletes, leaders at their sports. We always thought the problems were related to puberty and the ADHD. More and more ADHD meds were applied. No more weekends off the meds - because our house would be destroyed.

As 2008 began, my own allergies flared. When the doc offered Singulair, I looked forward to feeling better. Within 48 hours, I could breathe at night, and the tightness in my chest went away. Even my allergic dermatitis improved.

Then a weird thing happened. I got lazy. I heard myself saying things like, "I don't care if I'm fat." I stopped doing my evening chores. I stopped pursuing my hobbies. I almost stopped making dinner. I was wondering why I didn't care, but I didn't care enough to pursue that, either.

Then it got worse. I couldn't handle the least criticism. I was in tears over almost anything. Within a few days, I was trying to find a way to leave my family. I just didn't care about anything any more.

The water-cooler crowd at work was chatting about the news reports about Singulair and suicide. I started to wonder: gee, doesn't depression preceed suicide? Maybe this hopeless feeling I had was related to the Singulair.

So I stopped taking it. 48 hours later, I started to laugh at jokes again. Five days later, I cleaned my kitchen. Now it's been three weeks and I'm back at my hobbies and loving life.

Two weeks ago, I realized that the never-ending laziness and argumentation we've been getting from our twins might be related to Singulair. I checked with the ADHD doc, and their general doc, and got the go-ahead to discontinue the medicine (although not both of them at once). I did this without telling anyone: not the twins, not my husband, no one.

Forty-eight hours after the first kid had stopped taking the Singulair, I came home to a grinning, hugging, 15 year old, who sat me down at the kitchen table to explain the strategy he'd designed to study for his upcoming exams. I was speechless and numb. I didn't tell anyone that he was no longer taking the Singulair (he takes a variety of vitamins and ADHD meds every day). The next day, my husband called me excitedly: the kid was cooperating with him! He didn't know what to make of it. I kept him in the dark for a few more days.

The other twin had been on a lower dose (5mg rather than 10 mg). I stopped his medication as well. The change in him has been more gradual.

Neither of them takes ADHD medicine now on non-school days. They are happy and cooperative. We ask ONCE for chores. There are still a few arguments and stormy moods - but I no longer wonder what's going to get broken next. And they seem to love working as hard as possible at their sports.

The good news is, we all feel better. The bad news is -- how did this happen? How can it be that such an obvious side effect was missed?

It's not like the effect of montelukast on the brain is unexplored. Try searching on "montelukast brain ischemia" - there are many studies that show that montelukast (Singulair) dramatically reduces brain swelling. What does it do for an uninjured brain? Does it dehydrate it? Deprive it of nutrition? If I had to characterize the behavior I saw in my twins, it's this: they acted the way hypoglycemic patients do, when they're late for their next snack. REALLY GRUMPY.

Or do some research on migraines and Singulair. There's an effect there, too. Many asthma patients on Singulair report that their migraines improve.

So the drug clearly affects the brain, and Merck's position that Singulair doesn't cause suicidal ideation is almost irrelevant. The fact is, montelukast has a significant, often-studied effect in the brain. That effect is not fully understood.

In our house, the effect of montelukast on the brain has been significant. We have dragged two kids to many psychiatric evaluations. We've spent hours and hours with teachers and principals and counselors, trying to understand why they just won't get their work done. We've used every performance-management trick in the books to get them to work - without much benefit. The kids have swallowed an awful lot of stimulant medication because it was the only thing that controlled their rages. Who knows what their teachers think of them - are they forever branded as the lazy kids? And we are lucky. From this forum, I've learned that it could have been a lot worse.

My 9 year old son has been on Singulair for about four years for asthma and allergies. It did wonders for his asthma and allergies. However, since starting the medicine, has experienced rages, anger, impulse control problems, extreme mood swings, violent and destructive behavior, repetitive behaviors, bed wetting, weight gain, bad self thoughts, ADD, paranoia, peer social interaction problems...shall I go on? He sees a psychologist once a week for counseling and a psychiatrist periodically. He was diagnosed last year with major depressive disorder and mild ADD. He was placed on an antidepressant, an antipsychotic, and an ADD med. My big-hearted sweet boy gradually faded away. When I heard the news about the FDA investigation last week, I did some investigating myself. What I found was gut-wrenching! The Singulair went in the trash. This drug has stolen four precious years of my sons life and made the entire family suffer! We have been through hell. Only four days off the medication and he is already feeling better and looking like my happy boy again! We are slowly weaning him from his psych meds. I am full of hope now for him and his future and my family's weel-being but I am FURIOUS at Merke!!!

This fall, our 3-year old son went on singulair to combat seasonal allergies and "reactive airway disorder." Shortly after he started the medication, he started having terrible mood swings and when he would get angry, it would go into a rage. This was not typical for our son. We thought that he was entering the awful 3-year old stage and that he was starting to show behavior problems. We have been working very hard with him to help him control his anger and moods, but we will be taking him off singulair tonight to see if that makes a difference!

I have a seven year old Daughter that has been on singular for 6 years. The first 3 years she only took it occasionally but the last 3 years she as taken it every day. Also in the last 3 years she has had trouble sleeping all the way through the night she would wake up because of night mares and was afraid of sleeping alone and having mood swings that you would not believe she would go into rages that would leave me in tears because of not being able to help her and after about a year of that i took her to a Psychologist she was given a sleeping pill and was tested for learning disabilities. when they test a child they also ask the parent and the teacher a lot of questions about different situations the results of that test made it sound as if all of this behaviorally problems with my daughter was my fault be cause i did not have a good support family i think that was because i am a single mother but they also said there was nothing essentially wrong with my daughter. all of the things that i have read tonight sound just like the problems that i have had with my daughter and my daughter will not be taking Singular i know that they say that we should not be stopping the medication without talking to our doctor but if singular is the reason my daughter is acting this way then i can handle a runny nose better than a scratching bighting hitting whirlwind that she becomes in her rages

I'm in the same boat with so many of you parents. After MY parents sent me a link to the news story, I broke down in tears. My 8 1/2 yo daughter has been taking Singulair (5mg) daily for 5 years.

She is the oldest of 3 and has some emotional issues we've always attributed to her personality: mood swings, rage that will last anywhere from 2 minutes to an hour, over-emotional, and yes, even at age 5 she said she wished she was dead. We were shocked, wondering where in the world that idea had come from. I can't say it was caused by Singulair, but it very well could be a factor. Our other two children just don't have the same issues she has with emotions. As a side note, over the years (and just yesterday as a matter of fact, she has complained of severe leg pain. Again, I never thought that would be a side effect of this medication.)

Lately, her allergy/asthma doc has been prescribing more and more meds for her and we have chosen to not give them to her. We will certainly remove Singulair from her regimen. As a parent, who can we trust? My child can't breathe if she's not on some sort of medication.

I would like to know, as another parent asked, if these side affects will subside once Singulair is discontinued.

I must say that Singulair works to control her allergy-induced asthma, but after seeing the story, reading comments here, and seeing my own daughter's behavior, I don't believe it's worth the risk. She's off this medication as of today!

I'm praying for each of you and your kids!

I am shocked as well to see the news tonight, my son who is now 8 was on Singulair for about 2.5 years, he has not been on Singulair for about 2 years now. But my husband and I have been questioning why he has had behavioral issues for the last few years, he has rages, mood swings, and has even mentioned that he's going to kill himself, and is very destruct full. He has been recently diagnosed as A.D.D. but I am wondering if the Singulair had any lasting effect on him for him to be going through these horrible behavioral issues

I'm not surprised at all to hear about Singulair being investigated for causing mood changes and suicide. My son was on singulair 6 years ago for a year when he was 5. He underwent very severe mood changes, including insomnia, rages, severe anxiety and panic attacks. We ended up seeing a psychologist about his violent moods, but it took us a year to connect it to Singulair. When his dosage was raised due to growth, he started experiencing disabling anxiety. He was terrified to leave me and had obsessive thoughts about me dying. Things culminated with him being terrified to swallow any food out of fear of choking and dying. When he stopped eating for three days, I began to search the Internet and found references to Singulair causing anxiety in children. He never took singulair again, and was able to resume eating within a few days. He was back to his normal self within a week. Hopefully, now doctors know about the incredible risks for kids with this medication and can warn parents to watch for side effects if they indeed do put their kids on this medication.

I started taking Lamictal about six weeks ago for epilepsy. Now keep in mind, I was on Dilantin which worked great for 17 years and then suddenly stopped working. I have been in medication hell since then. First Topamax made me dumb as a rock. I would space out all the time. Worst drug ever. Then Keppra which was better in that my memory/ability to speak came back but I had these intense ups and down. I had rages constantly. Now I'm on Lamictal. So far, it's better than the Topamax and the Keppra, however the dreams are very intense as are the night sweats. I'm also experiencing much hair loss. Fortunately I have a full head of hair but I'm afraid I will eventually lose it all.

I have not taken a drug with so few side effects. Dose up to 200mg. Outstanding med for bipolar disorder.

My son Colin who is 9 has been on Singulair for about two years now and I am getting very concerned about him. It started a few months back where the school nurse sent him home a couple of times because of an unexplained hives only on his hands. Every time the dog scratches him, the scratches swell . Yesterday he had red blotches just around his mouth. We are talking about an extremely shy boy who all of the sudden will not listen to the school teacher. He lashes out and goes into these unexplained rages.He complains of stomach pain and is nauseas all the time.He does get headaches and seems depressed.Last weekend and this weekend, friend of ours experienced the whole freaked out incident. One minute Colin will be fine, the next minute seems like a panic attack. I really was starting to believe it was behavioral but I now am convinced it is his medication Singulair!!

I feel Singulair has completely destroyed the beautiful, peaceful personality of my 6yo. Although it's helped with her allergies and allergy associated asthma, this poison has destroyed her life - and all those around her. Her fuse is so sort, there is none. She's gone from a calm child to a spaced out, angry wild child - throwing tantrums like she's never thrown, hitting, screaming, shouting. She has no reasoning capacity, she often seems like "the lights are on but no one's home", she's absolutely inconsolable when in one of these "rages". The aggression is unbelievable and uncontrollable. She, herself, feels out of control and explains she wants to stop screaming, but can't. She hates herself, poor little angel. She's also experienced tummy pain, headaches and numbness in her extremities. This drug is despicable. We should all demand that it's removed from the market...immediately! And what about the doctors telling us there are no side effects? Children could be put on anti-depressants or ADD medication to relieve the side effects of allergy medication, and it's considered to have no side effects! Incredible! Does anybody know how long it takes to get this poison out of the system? I took my little girl off it two days ago and she seems to be experiencing severe withdrawal symptoms.

My 6 year old son has had all of these more or less. He has been on Singulair for about 5 months. We took him off last Friday when he started having seizures. It is only now that we are connecting the things he has complained about. He is still going through testing but everytime a test is done it is negative. He is in perfect health. The dr.s are stumped. What happens is, he smells a wierd smell. Then he sees lights. After this he has a bad headache and becomes weak so he lays down. Shortly thereafter he stiffens and starts shaking his arms and legs while clinching his hands. He also grunts and makes a buzzing sound and appears as though he only breathes out. the dr.s say it is not seizures but movement disorder and if it is Singulair it should be out of his system within 3 days... He is still having the seizure type fits and its been a week since we took him off singulair. He is still losing his temper and having horrible dreams as well. Cat scan was normal, EEG was normal, blood work is ok, they want to do an MRI but does this sound familiar to anyone?
