Doxycycline Hyclate and medicine

I started taking Doxycycline Hyclate 100mg on oct 25,2009. I have had anxiety, its been something i have been battling with up until 2 years ago and since then i have had no anxiety attacks. When i started taking the doxycycline, i started to become anxious and starting having anxiety once again. I have also become very shaky, i have a hard time swallowing pills so i brake the capsule open and put it my cup, put just a little bit of water in there and mix it around. could this affect the way the medicine is suppose to work. i have no other option because i have to take it to clear my infection, but i don't want it to harm me. please email me at ****** if you can help.

that medicine has killed me ,i have been taking doxycycline from last 6 months and since 2 months i start having severe joint paints thou i started feeling little pain when i started that medicine but i didn't pay attention but now i feel my self very old my whole body hurts and i m only 25 but i feel like killing myself ...my each part of the body hurts ,i stop taking doxy from last one week now i m taking Motrin to get rid of my body pain i don't know how long it will take for me to recover ,even my throats hurt everything of mine gives me pain ,i m very depressed i wish i get over with my body pain soon :(

I found this site 12 months after beginning Doxycycline for acne. A year ago I was the happiest person that I knew. I was a junior in high school and was very involved, liked sports, and had many friends. Me and my girlfriend were happy and to be honest, I had literally not felt happier.

A week ago I had come to the end of my rope. I literally decided to commit suicide. I finally reached out to God for help and I feel like he has saved me. About half an hour after praying for help from where I was I found this site. So, without further adieu, I am going to detail how horrific and absolutely from hell this drug is. ****PLEASE, I BEG YOU, IF YOU OR SOMEONE YOU KNOW HAS BEEN AFFECTED BY DEPRESSION, ANXIETY, OR ANY OTHER SIDE EFFECTS DUE TO THIS DRUG, PLEASE CALL THE FDA SIDE EFFECT HOTLINE. THIS DRUG IS FROM HELL***

I broke up with my girlfriend because I would sit at home and think for over 12 hours at a time that she hated me. As a result of this racing thoughts, when I saw her or went on a date, I would have nauseating anxiety for literally no reason... This anxiety continued for about a year until I had almost lost every friend I have ever had. It wasn't their fault, just that no one else knew how to respond to this sudden change in me.

Racing thoughts were terrible. I couldn't sit in a room without thinking thousands and thousands and thousands of negative thoughts from hell. I would think of how my family, and my friends, and my girlfriend all hated me. Now, after discontinuing this medication, i realize that it is all a lie.

The depression was horrific. I would literally have rather had a serious physical disease for the past year instead of feeling like this. I wouldn't go to parties, I would sit home and cry. Mind you, NOTHING happened to make me feel like this. Absolutely nothing. I thought about suicide about once a week (at least). I honestly didn't know what to do.

Mood swings were awful. I would change life goals and life core beliefs within minutes. Everyday I would become a different person at least 10 times throughout the day. I would go from nice, to sad, to motivated to start my own business, to thinking about signing my soul to Satan all in one day. These are just a few of the horrific thoughts. Dark thoughts, thoughts from hell.

I can report no physical side effects, but honestly I have been through so much that I can't stand it with this drug. I would like to thank my Lord and Savior Jesus Christ for helping me realize that this drug can absolutely ruin lives. I think everything happens for a reason, but people, hear me. I write with tears in my eyes right now and I look back on all of the lost time and all of the friends and all of the opportunities that have literally flown passed me. Just know that you are not alone. Stop taking this drug! And start raising awareness!

Within 5 hours of first dose, I had "severe body aches" like those with the flu. My joints and muscles hurt so much that night that I had to call my parents to help me take care of my kids the next morning. I told the doctor who prescribed it, and he said to try to stick it out for the week...what horrible advice! Thinking it was crazy advice, I reluctantly took doses 2, 3, and 4 and experienced the joint/muscle pain each time, but I guess I just somehow tolerated it as if I had the flu. My hands became rather puffy as well. After the 5th pill, I woke up in the middle of the night with HORRIBLE joint and muscle pain, which was so awful that I could barely move; I was able to move a little bit, with extreme pain all over my body--particularly my knees, wrists/hands/thumbs, feet, and shoulders. I felt and heard unnusual snapping, cracking, and popping all over my body when I would move around at all. I stopped the med immediately, and noticed some improvement over the next several days. It has since been 9 days since the last dose, and I still have considerable pain in my knee, my thumbs/wrists, and arms. Unable to do my regular exercise, I tried gentle swimming and light water aerobics several days ago, but found even that to be too painful to do. I'm still unable to pick up my young children, drive without pain (mostly in right knee and muscles connecting to it, when pushing the brake) and am still somewhat limited in typical daily activities. Also, for the last 5 days or so, I've had a strange nodule present on a tendon in my thumb which has been hurting since taking the antibiotic. This has been a very frightening experience, to say the least.

I was prescribed this medication for an infection I have. 100mg 2 times a day. About 30 minutes after I took it I was violently ill. I was dizzy and slightly delusional. I got sick for about 45minutes. Thanks good I only had water and ginger ale in my stomach. I felt like I was on fire. And I could not stop the feeling of having an anxiety attack. I have stopped taking it and am going back to see my doctor. I think this drug is useless.

I have been taking Doxycycline Hyclate 100mg twice a day for 6 days for a tick bite infection. I've developed a rash on the palm of my left hand. It doesn't itch, but burns a little. My doctor says it's not an allergic reaction. I need to get rid of my illness, and the rash really doesn't bother me that much. What I fear are what internal side effects I might be having from reacting to the medicine.

Has anyone experienced tremors and anxiety from taking this medicine? I was in perfect health before a dental procedure turned bad made it necessary for me to receive this medicine. I have been done with it for a few weeks and feel like I am falling apart.

Diarrhea! Only one dose taken and after reading these experiences I am puffing myself up to make it through the next seven days. Wow, I am a bit freaked out, but I am scared not to take the rest of this Doxycycline now that I've already started. I was told to take it to avoid a possible infection from my surgery.

Which would be worse?! I had the foresight at least to pick up a probiotic on the way home and will take it at a measured time away from my antibiotic dose. I hope it helps. I am also eating a full meal before taking the Doxycycline. I will report back on any continuing or additional symptoms and whether I feel the probiotic was at all effective in lessening the drug's side effects. It may be difficult to distinguish the side effects of my surgery from the medicine, so I will attempt to be discerning. To illustrate: I am dizzy and tired, but either could be the cause of these effects.

To anyone else taking or about to take Doxycycline - ask your doctor if this drug is mandatory or if another, less toxic, drug will suffice. Doxycycline is a heavy duty antibiotic and therefore it is bound to make the human body quite ill as it works it "magic". Take care (and a quality probiotic)!

I'm 16 and I was prescribed Doryx (doxycycline hyclate) about a month ago to treat moderate acne. I've been taking it since then and I'm supposed to be on it until September, however, I'm not sure if I'm going to last that long if I keep taking it.

While I didn't experience any side effects for about the first week, after that, it turned terrible. I experienced insomnia, which included not being able to fall asleep, waking up about 5-10 times a night (often being unbearably hot and sweating intensely, even thought it was a cool 70 degrees F in our house.), and to make it worse, i was up for about half an hour each time i woke up. And to make it worse, I was always tired through the day, but I still couldn't sleep.

While sleeping I had very vivid dreams which is unusual for me. I also had pretty bad stomach pain, and terrible pain in my kidneys for a few days. It felt almost like a kidney stone.

I also am very rarely hungry and almost get sick when i eat. Since on this medication a month ago, I've lost about 10 pounds just because I can't eat.

I've had a difference in mood as well. Most of the time, I'm happy, but now, I have very noticeable mood swings and periods of depression.

And the medicine ISN'T EVEN HELPING with my acne.

Oh, and these are only SOME of the side effects I've had. So, right now, I'm not sure if i should quit the medicine, or if the medicine will put an end to me first.

i received this medicine for a bacteria infection the first time i took it i threw it up a 1/2 after taking this, i took it an hour before a meal, i feel dizzy, blurred vision bad stomach pains and bowel movements. i called my doctor about the vomiting and she told me to take crackers with it, well i only take 1 a day now *not what i was told to do* and i still feel awful i am going to stop taking this drug its awful

I've been on doxy for about 10 days. I've never had problems with "photosensitivty" when it had been listed as a side effect on other medications. Totally disregarded the warning. I was put on it for some problems that might arise with acne due to a hormonal injection. I was going to the Florida keys in a few days and thought I should go to a tanning bed to get a little color so I wouldn't burn down in the Keys. Within a couple of days my hands began to tingle, burn with warm water, freeze with cool water. It was like my skin was burnt off and my nerve endings were exposed to the elements. While in Florida with my feet and hands in bandages to keep the heat/sun from causing pain I noticed blistering and still have them. I thought I had shingles, even though I had it on both sides of my body! Had an increased heart rate and 2t pitting edema in my feet and calves when flying home and increased itching on feet and hands. Very nervous at this point! I massaged my calves to increase the flow back towards my heart and it seemed to help. I am also experiencing GiI problems as well, severe heartburn and bloating. My son said I looked like I was pregnant! I can't wait to talk to my Dr. tomorrow and will stop taking this medicine. Thanks to all of you for your information. I'm relieved to find out what is causing all of this. I only hope my symptoms will go away sooner than later!

Dear lovely people.

Thank you so much for all your postings. This site was literally my salvation. Nobody who knows me believed that I could be so ill for so very long. Family and friends say that I am a very strong person and not phased by anything, but believe me, even I could not overcome the side-effects of this deadly drug. It even resulted in me having hallucinations. It is interesting to note we are not alone in this are we?. You have to have been there to fully understand how truly horrific the side-effects are. It is interesting to note that compared to other drugs listed on this site as to positive side-effects of any drug (most drugs listed have either none or perhaps 1 -2 listings) all 353 of us!!! have been so desperate to know why we have been feeling so very very ill. We have therefore in desperation tapped into this website. We can't all be wrong. Some of you like me were or are in your darkest hour, but please, please hang in there. I took this poison for four weeks as an anti malarial medication for my holiday and it was only last Monday did I feel fully up to strength. I will do everything in my power to stop this medication ever being prescribed ever again. I have had every single one of the side-effects listed on this site. It may take some time, but you will get better and when stronger I hope like me you will try and do something positive about what has happened by actioning why this drug is never taken again by anyone by any one ever again/. Never would I want anyone to feel as ill as this. I promise it may take some time but YOU WILL come through this just like I have. I would welcome any feedback from fellow users as to what action they may also be taking as to stopping the prescribing of this drug.

Keep strong.

Kind regard to you all.

It seems that everyone is having similar symptoms. I have been on Doxy for about 14 days now and I'm feeling worse every day. I am on it because i had been bitten by a tick and contracted Lyme disease. I don't know much about the disease but it has me freaked out. I started taking the antibiotic 2 weeks after being bitten; losing my balance and almost falling to the ground. I also had a couple of dizzy spells after eating. I seemed to feel a little bit better the first week of taking it but started feeling the side effects. It started out with the occasional dizzy spell then came the exhaustion, anxiety, depression, lower back aches, soreness in the back of my eyes, stiff neck, headache in the back of my head, flu like shivers, racing heart, and complete body aches. I also found out the hard way not to go out into the sun while on Doxy. Felt like the tops of my hands were being pricked with a million needles and burning. I wish I could stop taking the drug and be done, but I am already scared about the outcome of the Lyme disease. I hope I can feel normal again soon.

I am male aged 30. I took Doxycycline for Urine Infection, I stopped taking these after 11 days, because of the severe Hot Flushes and night Sweats. Its been 2 weeks now I'm off these capsules and I am still suffering Hot Flushes.

I hope I get better soon, It seems that this medicine has affected by testerone levels and testes (they have shrunk), and is giving me women menopause type side effects.

Has any body else have these effects, and got better after stopping these ?

To everyone out there that has issues with doxycycline...
Now i fully understand the old saying that nothing is free in life.

I got it for lyme disease 7 days ago, and it was one of the free prescripts from my grocery store (great i thought). Little did i know how powerful this stuff can be. For the last week i have basically had severe headaches and wanted to give up on life. I didn't want to work out, didn't want to go to work, had chest pains, muscle spasms, and DEEP DEPRESSION....
now i know why this is free, because after it gets you so depressed, they figure your doctor will put you on something to get you out of depression, a money making drug. This is probably the meds talking still (i stopped yesterday after what felt like a complete and utter mental breakdown). Regardless of my silly conspiracy theory, i am glad i stopped taking it, and i hope that i start feeling like myself again.

Last December I was also prescribed Doxycycline Hyclate 100mg for mild acne. I am 17. After a few weeks of taking it my acne appeared to have been getting better and I felt quite relieved. However, after about a month and a half of taking it, I woke up one morning with what felt like extreme heartburn. My stomach felt like there was a lump in it and in the middle of my chest where the esophagus and stomach connected, there was extreme pain whenever I swallowed anything. At first I thought this was just due to excessive acid in my stomach, but as it turned out it was the medicines reaction to a virus/cold I was getting -- the symptoms were nearly like an ulcer (which is what we initially thought). After stopping the medicine for about a month, I was fine and I started taking it again. Now it's been about the same duration of me taking it, and once again I feel as though I'm developing another case of what feels like extreme heartburn/an ulcer. Has anyone else had this problem?

Started Doxy 4 days ago. Supposed to have been taking 100mg twice a day, did it first couple days then forgot. Started back on it today. Almost immediately after taking the dose I noticed my face was itchy. I have tons of tiny bumps all over my right cheek up into my eye area and down the jaw area as well. Other than this I feel bloated as hell, I don't know if it's related or not. The rest of my skin feels itchy on and off but I don't notice any bumps anywhere other than the right side of my face (so weird). Any thoughts on why I might be having this reaction??

I was recently prescribed Doxycycline Hyclate for periodical dermatitis (contact dermatitis around the mouth) It started to get rid of this red, ugly rash right away, however, 2 weeks into the medicine, my head is killing me! I have HORRIBLE non-stop head aches. My head and face hurt like I have one monstrous head ache, and, aspirin does not help! I have also been so angry (hard not to be when your head is pounding!) I also had terrific nausea. Could not sleep at night, and, I had some weird nightmares! I stopped taking it and will be calling my Doctor today to tell him to give me something else.

My daughter was prescribed Doryx for mild acne- 150mg a day. At Track Meets she is complaining that she is dizzy (seeing black spots) after races. Now she says she has tingling in her hands and lips. They feel like they are on fire also. I had her stop the meds immediately and am waiting for the dermatologist to call back. If anyone had these symptoms how long does it take for them to go away?? email me: ******

I'm 41 and approximately 115 lbs. I've been taking Doxycycline Hyclate (100mg) for only 3 days now and so far I'm still feeling my normal self. I have 4 more days to take the medicine before completing my dosage and I hope to continue to feel the same way. I must say that when I take it, in the morning and early evening, I drink lots of water with it and I eat a complete meal, which is what I do with any prescribed medication that I may have to take unless otherwise specified. I don't know if this is why I'm not feeling any side effects, but so far it seems to be working for me.

There are all sorts of verified reported side effects, most of which were on the packing slip that came with my prescription. However, not all side effects are listed on the insert. I’ve come across depression and anxiety listed as side effects on other drug profiles for Doxycycline, so if they are among the symptoms you're experiencing, they very well may be due to the drug. My experience has served as a greaet reminder to research any pharmaceutical I put in my body so that I may make informed decisions.

Like many of you, apart from my current breakout from Doxy, I too experienced stomach upset, and, to a lesser degree, cranial pressure.

Be well. Cheers.

I started taking Doxycycline Hyclate for an infection....i had been taking it for about 4 days.....one night i take the medicine and i go to sleep.....i wake up the following day with the painful and disturbing sensation that something was stuck in my throat.....and drinking a lot of water to make it go away was in vain......in a couple of days i had trouble eating and drinking and also breathing - i felt burns in the upper back...constant pain.....so I just stopped taking them.....After a couple of days i go back to my doctor and try to explain all the symptoms and try to tell him that i think that it has to do with the medicine that he prescribed....he cuts me off "No, that,s not possible, the medicine I prescribed was for something else!" .....ok ....so I'm thinking "he's the doctor, he knows better, after all he went to school for that!!!!" ....so instead of actually listening to all my symptoms he takes blood test to see what is the cause of my pain; an infection? the liver? etc. etc..........and then at night I come home, I google the side effect of Doxycycline Hyclate and see that I am not crazy...that this happened to a lot of people and that I NEED TO CHANGE MY DOCTOR!!!! Oh, by the way, the doctor prescribed me Propoxyphene-N 100W/APAP (some pain relievers) and told me to take them 10 days without stopping even if the pain goes away!!!!!??????!!!!!!?????!!!!........................L.

I am so relieved to hear that I am not alone!! I was outside in the sun the other day, slathered with SPF 35, and I felt like my skin was burning off! After I moved inside, my lips, hands and even feet were tingling. The tingling worsened whenever exposed to cold temperatures (ie. cold water, freezer, even refrigerator). It is 3 days later and my lips and hands are still sensitive. I have a dark complexion and rarely burn. I'm glad I can blame the medicine and not a sun allergy!

I am so glad I found this!!! I too took this pill before bed without a lot of water and I woke up in the middle of the night thinking I was having a heart attack!!! I cannot eat anything without it burning like there is a ulcer in the esophagus!! I have been off this medicine for 4 days and I still am on the slim fast diet because I cannot eat anything!!! How long does this pain last? Is it permanent? I don't know whats going on I am starting to get really nervous!! If this many people are having the same problem we should file a class action suit this is ridiculous!! I cannot not live like this the rest of my life! I am normally a very healthy person and I'm only 29 so hopefully this did not do any serious damage! So does anybody been off of this and not feel like a flame thrower is in your chest anymore????

I've been on this medicine for almost three days now and had no problems, until this mornings dose. my nightly dose consists of this and two other medicines, one of which i take food with and i haven't had any problems outta that dose. but this morning i was running late and didn't grab a glass of water with my meds, instead i grabbed a coke. HORRIBLE MISTAKE! i was running around the house trying to get ready for school but i still felt fine. about ten minutes into my drive i burp and then i suddenly feel as if i'm gonna throw up. another 15 minutes goes by and i had to pull over on the side of the highway and puke. it was so freaking embarrassing and horrible. i still made it to class on time though. i have now learned my lesson. if it says take with a glass of water, it really means take it with a glass of water :/

Thank God for you all that posted! :) I don't feel all alone. I'm usually a healthy, strong guy that rarely complains. I've been on a 100mg 2x a day dose of doxy. The first week was ok. just minor stomach nausea. Then i noticed chest tightness, mood changes ( and on the norm im a really passive guy, in a good mood) dizziness, very scary panic attacks(mind racing with negative thoughts), headaches.. Its my 2nd day off of it. Still feeling nausea.. sharp abdomen pains, in and out of depression. I truly hope this thing goes away asap. Never again will i take this med. Very scary times.

I must say I haven't had the slightest problem with this medication. I am a small girl (105 lbs.) and most medications usually hit me pretty hard, so I am surprised to read so much negativity concerning this pill. I will say that I was thrilled at how fast it knocked out my sinus infection and I would definitely use it again should one reoccur.

I was prescribed Doxycycline Hyclate 100m for acne on January 20th 2009. Then, on February 6th, I took the medication at 11:00 only to wake up at 11:40pm with severe chest pains. I have never had anything wrong with me heath wise and the first thing that popped into my mind was the medicine. I went to the doctors the next day because the pain had become so severe and i could not eat or drink anything (even water) without feeling a sudden sharp pain. They did an x-ray and found nothing wrong. I was told it was probably anxiety and this medicine had nothing to do with the chest pains. I
went ahead and took it again last night only to still have chest pains so i decided to do research on this medicine and came to this where i found posts in which similar things were experienced upon taking the medication. I have just stopped taking the medication today and am hoping for the pains to go away.

i was wondering.... i only have one more dose of doxy left... and ive been taking it for seven days... and since Christmas eve ive had this constant burning head ache
its like my head hurts and im like hot all over my head my eyes even kinda burn
and its there as soon as i wake up ive taken my temperature and im normal
if i walk out in the cold i feel better almost immediately
is this probably the medicine??

After taking another medicine for an std I went to get rechecked and my doctor told me I still had it....so she prescribed Doxycycilne and the side effects i'm having from it are unbearable, nausea, cronic headaches, my chest feels tight and its often hard to breath....I only have one more pill left.....Thank god! i hate this medicine its horrible if your doctor prescribes it ask for something else....

Hello people - I've been taking Doxycycline for about 4 weeks now (for Chronis Prostates) and started experiencing aching in my muscles, mainly my legs (back of thigh, calf and behind the knee mostly) about 2 weeks back. It started very subtle and has got stronger each day. I don't know if this is a side effect of the Doxycycline or just some lovely new medical problem I'm developing - but I thought I should post up my experience in case anyone finds themselves in my position and they too want to know if anyone else has got worsening aching legs whilst taking a long course of this medicine. I'm going to speak to my doctor about this tomorrow and stop taking the drug. I'll update you all with another postas to how things develop. Hope you all get well folks!

I have been on Doxycycline for 6 days now. Feel much better after doc change my medicine to doxy.I was laying in bed for all that time with high fever, even when i felt better i kept resting. Drink a lots lots of water or other drinks to stay very hydrate. That is very important to drink all the time. It helps with breathing also. I still have problems with breathing what helps-is to keep your head higher then the rest body. If you laying down and feel pain sit and cover so you stay warm and still can breath. To get through this disease you guys have to be patient and don't move to much. Sometimes it takes 5-7 weeks to get some energy.

Is this normal, I have been on Doxycycline for 5 days for a urinary tract infection and from day one i had a sore throat with swollen glands, extreme anxiety and feeling pretty ill, yes it has helped my infection a lot but I have now developed very bad pains in my chest like extreme indigestion and finding it hard to swallow anything, even water, without it hurting??

Im thinking about talking to the Doctor Im feeling pretty rough at the moment and not too sure whether this is normal or not!!

Well, I have just started taking Doxy for a couple of days now and so far have noticed a change in bowel movements, appetite, a bit of nausea, my stomach has been feeling a bit bubbly and weird here and there. Also, it makes me feel high after taking it. And i know this sound funny but it makes my bottom itchy. Which is all really weird but over all I don't really care about the side effects as long as they dont become too extreme. I think as long as I take the medicine on terms that are best for me I will be just fine. I am just very glad to be getting rid of an infection that was causing me a lot more pain and discomfort than this med and will be glad when this is over. The biggest issue I have with the pills is getting them down my throat...I'm not a good pill taker and they make me gag. I can't imagine having to take them and deal with side effects for months at a time as some of you are doing so good luck to everyone!! And I also agree that doctors really do need to address the more serious side effects on this med! After coming to this site I will definitely take precautions.

I am on my fourth day of Doxy. Like many of the other posts I also experienced side effects not listed on my prescrip. info. sheet. The first day or so I did feel as though I was in a fog and was also very tired feeling. One night I felt like I had something in my throat and also burning in my throat. I was prescribed Doxy for having pneumonia so the tirdness may very well have been from that. The best advice that I can give that helped to relieve my side effects was to drink A LOT! of water when taking this medicine (20 oz) not the 8 oz advised. And to keep drinking water throughout the day and night. My side effects have all but gone away and I am starting to feel so much better.. Although I have not been in the sun it cannot be expressed enough that you should avoid the sun while on this med. And if you are having side effects try not to panic that will just intensify what is going on. Remember the side effects are sometimes better to have then the actual illness you are being treated for. But please drink tons of water. Also side effects can be reported to the FDA at 1-800-FDA-1088. If enough people call then maybe they will add new side effects to this med.

I'm not a person who usually has bad reactions to antibiotics but I've never been so miserable as I was taking this drug. I felt excruciating pain in my stomach all day, every day, while taking this medicine. I stopped taking it almost a week ago and I still feel like I have a big lump in my throat making it very painful to swallow. And the worst part is that it was prescribed to me "just in case", so I didn't even have to be taking it. Luckily as soon as my bloodwork came back negative for any bacterial infection things, they let me stop taking it, but like I said, I still feel ill and my throat is killing me.

I took 1 pill (100mg) Doxycycline HCl, went to bed, slept very groggy, exhausted. Next day, second pill, 1 hr later feeling nauseated, then severe migraine headache, thew up, felt like in a severe fever. This lasted about 5 hours then reduced to exhaustion, dizziness with some heartburn. It was intolerable. I also felt very depressed and negative.

One website describing a patent for a different formulation of Doxycycline reported that 31% of patients taking this experience nausea and vomiting.

Why is this drug so frequently prescribed?

Stop taking this drug if you have side effects.
After doing a little research it seems that the "Hyclate" formulation has many side effect problems. The other formulations (monohydrate or carrageenan) may be better. The Hyclate formulation is very rapidly absorbed and is acidic and can cause local damage to the stomach or esophagus. Some report these symptoms on this website. Also it seems foolish for this to be in capsule form, since this increases the rapidity of dissolving and probably also local damage. The drug is 'good' in that it stays in your system a long time and brings your body to a high amount of antibiotic rapidly.

I have never had a bad reaction to an antibiotic before. I'm glad this website allows for these reports.

I have been taking Doxy for a while now for Adult Acne. It clears my face right up.. I stopped taking it for a while to see if maybe I could have outgrown this adult acne (I'm 34) but no such luck.. Anyway, I noticed when I was taking the Doxy that my joints always HURT badly! When I stopped taking it they didnt.. And I started taking it again and yeah, they hurt again!! Does anyone else have Joint pain from Doxy???

I take 100 mg once per day..
