Doxycycline Hyclate and headache

I am on day 13 of doxycycline for suspected Lyme. The headache is unbearable and constant. Only relief is lying down. Decision day today whether to go the last 7 days (I will be in hospital) on Doxy or stop in hopes that I can return to decent health. Any ideas appreciated. I am worried

I had took my first doxycycline pill for my acne problem, I immediately felt a tingling upset stomach, but it was just that. The next morning after breakfast, I took another pill and felt heavy in my head. I vomit all the food. I had taken the pill for 3 days and I found a severe headache and tiredness all the day. But, i think i will continue the pill for another 10 days. Hopefully won't come out big problems.

Hello Friends, it's been a week after i finished my 21 day Doxy treatment for lyme, Im still feel lot of fatigue and joint pain, i went to see my doctor yesterday, he explained the fatigue is a normal side effect after finishing the treatment. I feel so weak headache and migraines. The doctor told me to take pro-biotics and vitamins to recover faster i just started taking the pro-biotics today so i have to wait how it goes. the dizziness, migraines and fatigue doctor said it's a normal symptom of Doxy,, I hope these side effects will go away soon. if anyone has the same side effects after the treatment please write me.
Drink a lot of water.

thanks for sharing your stories,, we are not alone here.

I was on doxycycline for three weeks because the doctor believed I had Lyme disease due to the slight headache, mild fever, and aching joints that I was experiencing. I was fine for the first few days, but then I began to develop some unusual symptoms. The symptoms fluctuated day to day, but I was never free from one or more of these symptoms: severe headache, chills, night sweats, tingling in my arms, weakness in my legs, ear ache, numbness in my face (especially my eyes and lips), anxiety, depression, insomnia, pain in my eyes, and neck, and stiffness in my jaw. At the end of three weeks, I seemed to have more Lyme symptoms than before I began the medication. My Lyme test was negative, but with my continuing symptoms my doctor recommended that I take the medicine for ten more days, and retest for Lyme. The first day back on the medicine I was sicker than ever. I waited it out because the doctor insisted that it was the best thing to do. I finished the medicine, and the effects were less intense. My second Lyme test was negative. I am being tested for Fifth's disease (my son was ill with it just as I began to experience my swelling joints - a condition that can not be treated, uggh). I seem to get worse if I don't drink all day and night - a lot of water is needed, all the time. The effects also increase when I go to bed, recline on the couch, allow myself to become nervous about my condition, or over work myself through the day. I was at the pediatrician with my son yesterday, and mentioned my problem, wondering how long it could take to get the medicine out of my system. She told me it could be as long as a few months. It's been two weeks since I took my last pill.

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.

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.

i have been prescribed doxycycl hyc for uti infection and been taking this for 3 days now and on the 3rd day felt sick to stomach,headache ,severe anxiety and confusion also hot and cold and frequent urination this pill is horrible. just wanted to know if this goes away after you stop taking the pill cause i still feel pale and not myself and haven't take it for 12 hours..i will never ever take this crap again...

okay so Im taking this cap, because im trying to get rid of an infection. The side affects are killing me slowly. um, this is the fifth day and the headaches, dizziness, being tired all the time. my eyes are loosing vision. I think i will stop... from reading all the other things i have read about this stupid drug.

I was prescribed Doxy 100mg twice daily for 14d for a Mycoplasma pneumonia. Day 6 I started to get a bit dizzy and some changes in my vision, sort of having a hard time to focus but I just though it was symptoms of fatigue or just being hypochonric. From day 8 I started to get really depressed and felt that I was going to die and that everyone was leaving me. On day 10 I also started to get anxiety attacks and had extreme difficulties to concentrate on anything. By this time I also got tremor, weakness and tingling in my arms and severe neck pain. Throughout this time I was aware of the risk for benign intracranial hypertension, but I didn't get any headache or nausea until d 16, i.e. 2 days after I stopped the medication. I never had fever. I then dropped 6 pounds in a week and had a hard time eating. It is now 6 weeks since I stopped taking the medication. My pneumonia is totally gone. The depression/anxiety is almost gone although some social withdrawal and lack of initiative still remains. It's still a bit up and down but much better. My neck pain is still there but is also getting better and I only have minor tremor in my arms. The visual changes still persist but every now and then I feel like my old self again for a few hours/day. The whole episode have been, and still are, the worst experience of my life. I keep my fingers crossed that it will all go away over the next few weeks.

I was prescribed Doxy one week ago to treat a sinus infection, and have been taking it twice a day (100 mg x 2 = 200 mg a day) and one week later i am MISERABLE. The migraines I've been feeling are indescribable. The body aches and pains and the fatigue is miserable. Ive never had a headache so bad as this. Also I eat a little bit then feel so full and disgusting it's unbearable. I will NEVER take this drug again.

I was prescribed a 14 day course on the 9th March, I experienced headache, burning of the throat when taking the tablets. But now am concerned because I have missed a period and just feel very tired, anxious and feel very low, not my normal self. Can anyone advise if they have had experience of missed periods and how long before your cycle goes back to normal.

Thanks for your help

Kind regards

I started taking doxy for my acne but developed severe headaches about a week into treatment. At first, I thought it was because I was pretty stressed with college and not sleeping much but I noticed I would get a headache at about the same time after taking doxy everyday and now think I can't sleep because of it. I also wake up with tightness in my chest (couldn't sleep one night because it was so bad), I'm constantly dizzy, and just have the headache feeling that one gets when hungover. I'm so angry that these symptoms aren't in the side effects because I was blaming these symptoms on other things and would have stopped taking it earlier if I knew...I just hope that I get back to normal and don't have any permanent damage to my brain.

I am glad I found this website. I thought I was losing my mind. I had a migraine for 5 days before going to the doctor. He didn't think the headache was from the Doxy. Ended up in the ER for the migraine, I was literally at my wits end. They gave me the cocktail to get rid of the headache and I woke up with it the next morning. I stopped taking the Doxy and started on Levaquin. Finally back to myself, no headache and energy.

I finished with a 10 day dose of doxycycline 3 days ago. At about the 7th day, I started having nausea, loss of appetite, headache, sore and dry throat, sensation of burning on my skin (especially my arms), severe muscle pain in my upper back shoulders and neck. After I finished with my 10 day dose, the nausea and loss of appetite mostly went away, but I am still having headaches, sore throat, muscle pain and the sensation of burning on my skin. Does anyone know how long these side effects will last?

I have only taken 3 - 100mg doses and that's enough for me. The doctor prescribed it for a sinus and bronchial infection. I thought I was just getting much sicker but now know it is the doxy after reading the posts. I have serious nausea, headache, heartburn, feeling like something is stuck in my throat, upper back pain and all day I felt like I couldn't keep my eyes open. I didn't feel half this bad when I went to the doctor. I will call her tomorrow and ask for something else. I have never had a reaction to any antibiotic other than an occasional yeast infection. Thanks for all your posts!

Thanx for this site. I took Doxy for 3 days (100mg twice a day) and i woke up with a terrible headache on my right forehead. I took ibuprofen then my left hand started shaking and my heart was beating so fast. I ended up calling 911 thinking something was more serious with me but by the time the paramedics came my pulse and heart beat were normal. Almost 48 hours later i still had the headache and now was having shortness of breath, feeling tired, back ache, panic attack and light headedness. I called my DR and she said i probably just needed some rest. No mention of some possible side effect to doxy so i used my initiative and googled this stupid doxy drug..Wow the results were very helpful and now i know its the doxy doing this to me for sure. I stopped taking it right away which is after only 3 days after but my body hasn't gone back to normal. No more shortness of breath but still have back ache, Oh and for some reason i cant sleep..its 5 am right now and am on my computer..so i think i'll add insomnia to the list of side effects..NEVER AGAIN WILL I TAKE DOXY

ok so i got sick ( pretty sure i caught it from school ) on a Friday sick as a dead man. lots of sneezing and runny nose ( and i mean machine gun sneezing with waterfalls of snot ) sometime during the night i start coughing out phlem and now wheezing when i breathe n i had a fever , dizziness , well diarrhea comes in play and on Saturday i ate completely nothing.. i was scared after this because i was starving and couldn't even force myself to eat something to stay alive.. well the only thing better about Sunday i was able to manage some cereal for breakfast and a fajita for dinner.. coming Monday i stayed home from school went to see my doctor and he prescribes me "doxycyline" the doctor told me to get tablets.. but i ended up with capsules.. well wen i got back home i took one and immediately felt a kind of high ( like right now ) .. yea so today is Tuesday and i chose to stay home again.. and i just took my 2nd pill... im really starving n i think the only reason why im still typing is because of this pill...yea i have a really bad stomach ache / headache ... loss of appetite kinda wish i was dead feeling... im 18 and should i stay with this med? i don't even know if i can go to school 2morrow i have a doctors pass only for mon and tues.. i cant sleep .. i taste and smell this horrible taste i cant describe .. this is only the 2nd pill....and if i die in a week or two i think its bc of this drug .......

Taking Doxycycline hyclate for bacterial infection. I am on day 6 and the headaches are getting worse. I woke up last night at 1 AM and felt Nausea and a severe headache. I have to take this with a small meal or I will be in the bathroom until my next dose. I have diarrhea, headaches, DEPRESSION, no patience with my kids or wife, no sexual feelings, tingling lips that are starting to crack in the corners, dry mouth and no energy to do anything. I feel better on it, then I did without taking it, but If this does not take care of the so called bacterial infection, then I will be asking for a different MED next time. This stuff is very tough on you and if you can get something with less side effects, GET IT!

Am on my second 3-week course of doxycycline for Lyme disease since the first go round didn't eradicate the infection. Have all the classic side effects mentioned, however the stomach ailments are GREATLY alleviated by taking a strong (70 billion parts per capsule) probiotic. Take it half way between the 2 doxycycline doses and although it isn't magic it does make a difference.
Although I have no appetite, I try to graze lightly on foods that appeal to me throughout the day and that seems to help with many of the horrific side effects.
Also, my MD suggested I take Aleve and NOT Ibuprofen for headaches since the Ibuprofen can cause a "headache" kickback (and causes stomach pain). Don't know if that's true, but the Aleve seems to help a little.
Worst side effects for me are utter exhaustion, dizziness, stomach pain, sore throat, and a head that hurts feels like it is filled with wet cotton. Also heart palpitations which may be part of the Lyme disease.
Hope some of this helps.

I have to take Doxy for 2 weeks twice a day. I have all the same side effects as everyone has listed here... very down and depressed, itchy pimple rash all over legs, face, neck, chest and back of shoulders, cold sores, severe headache, bloating, stomach pain, tiredness, lack of interest in anything, dry mouth, tingling toes and anxiety. Can't wait to finish the course, but am disappointed to read that the side effects carry on after stopping, does anyone know how long it takes for them to subside?

wow, quite worrying, was prescribed this for an infection after a womb biopsy, The stomach pains are awful,sharp every few minutes,nausea as well, i feel so ill, i am in bed i just cannot function,

Severe headache, fatigue, diarrhea, and nausea, stomach pain that you wouldn't believe. I have common side-effects to most antibiotics so I wasn't worried at first but now that I have read all these posts I am getting pretty nervous. Last night I was back in the ER for the second time in three days because the lymph nodes and glands in my neck were swollen. The doctor gave me a CT scan and discovered that I had acute bilateral infections in my lymphnodes. An infection that I didn't have before I started taking the medication. This drug is horrible and I don't recommend it to anyone.

I have had the worst period of my life and a headache still, after being off of it for over a week. my stomach is also still messed up. how long does the side effects last?

Hi neverybody,
I was on day 4 of this antibiotic for sinusitis when I woke with severe neck stiffness, (unable to do chin to chest). This progressed to headache and I remembered then that I had pain in my eye the night before. I also had profound sleepiness on night 4. I work nights and this was affecting my judgement. I felt very low on night four and emotionally labile.crying came easy but for no real reason.
My shoulders are sore and my neck still aches but it is not as bad. i did not contact dr. Should I? I stopped before finishing the course on day 5.

Good luck to everyone and I hope your are all well soon,

This drug seriously needs to be pulled! its not worth ending a relationship over, i almost well was single because of it...gave me severe mood swings, depressed, made be feel not only sick but i couldnt eat anything, felt like someone was stomping on my chest, its all bull, and no one should even take this...pretty sad that every website i have been to about this drug, just says SYMPTOMS: Nausea, Headache, Dizziness, and Vomiting.

ADA needs to pull it because it does NOT do that job its supposed to. tha mood swings started off very mellow, then after 3-4 days of taking it, its coming to my attention it IS NOT me.....I was getting severely depressed when got into a fight wit my girlfriend. and i almost jumped out fo tha car at 70MPH because of this. Regardless of wut anyone says i am not right in tha head and wut not, i am so...just these so called Antibiotics messed wit my head. i erge everyone to boycott this use of this so called drug DOXYCYCLINE HYCLATE 100MG Caplets. If you wanna continue to be screwed wit, i then suggest you to stay on them for some tha symptoms are better for over half they are bad. My opinion....they are like a Anti-Depressant. If you take them and you are NOT depressed, moody, or have some kind of prob and when you start taking them you do have those probs, but if you do have those probs then you wont have tha bad probs is psychology and kinda hard to explain on wut i mean gonna have to figure it all out for your selfs. Because right now still coming clean from theese, i stopped taking them 2 days ago and still in my system a bit. so yeah i hope didn't bug anyone

I started taking Doxycycline on Jan 22, 2007 for Lyme Disease. I usually get nausea and/or vomiting with most antibiotics so I try and take precautions. The first day I took it I had nausea, headache, dizziness and a feeling of being "out of it". by the 3rd day the dizziness and the feeling of being "out of it" was gone but after I took it in the morning within 1/2 hour I started feeling severe esophagus pain. It's not like heartburn because it's right below my rib cage. That night I started noticing feeling like there was a lump in my throat. By the next morning the lump felt like a huge knot. Now, It hurts every time I swallow, the esophagus pain never ends. Last night I spent the night crying feeling like everything was hopeless. I thought it was just because I've been dealing with the pain from Lyme and now the pain from the medicine now that I read this message board, I wonder if the hopeless, despondent feeling is from this medication. I have 2 more weeks on this I don't think I can take it that long. I haven't eaten anything because it hurts to swallow and it burns. I cry all the time. I did not read that depression was a side effect but it seems a lot of people are experiencing the exact same symptoms. I don't know how some people have been on it so long. Just the thought of taking another is depressing me beyond belief.

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.

EVERYONE PLEASE EMAIL THE FDA ABOUT THIS, NEEDS 2 BE RE CALLED ASAP, I AM 14 HAVE BEEN TAKING THIS FOR 2 MONTHS, HAVE HAD HORRIBLE SIDE EFFECTS, CAN BARELY BREATHE, PERMANENT DAMAGE IN STOMACH, LOTS OF STABBING PAIN, NO ONE SHOULD BE ON THIS, REPORT YOUR SIDE EFFECTS TO THE FDA SO THEY CAN RECALL IT, I DON'T WANT PEOPLE TO SUFFER LIKE ME AND ALL THE PREVIOUS COMMENTER'S. THIS DRUG IS DEADLY, BEWARE! DO NOT USE IT!!!!! I AM SERIOUS

I took Doxycycline Hyclate one night before going to bed. Big mistake. It was still in my throat when I woke up the next morning. I assumed the pill would eventually go down on its own. Boy was I wrong. The pill was stuck in my throat for approximately 4 days. I finally called a local clinic and one of the nurses told me to take some maalox and drink warm water. The maalox helped the pill go down. I also tried goggling with warm salty water. Then two day later, I had a headache so I took a ibprophin and drunk some apple just about an hour later. I started feeling nausea and I had stomach pains for about 15-20 minutes. All of a sudden, I began to vomit apple juice. I took a nap and when I woke up, I ate lunch and I had no problem eating. I no longer felt the heartburn while eating. I didn't even feel the pill. I am so happy that the pill is gone. I guessing it was the acid that's in apple juice. If anyone is looking for advice on how to make it go down, I'm pretty sure you could skip most of the steps I took and just try drinking the apple juice.

I'm taking doxycycline for dry eyes. I was in the sun for several hours yesterday and I feel nauseated, tired and have had a headache for 12 hours. Can I do anything to combat these symptoms?

I have been on this antibiotic for pneumonia for a week. I already have a possible ulcer and have a prescription for zantac. I am on 100mg BID for two weeks. Since taking this medication my ulcer has become much much worse with frequent heartburn and a lot of drowsiness/lethargy. I feel like I float through my day and am confused and using the wrong words a lot, and just not paying full attention to anything. I have a constant pain right under my sternum that flares up and a lot of mid to lower back pain, esp. at night. I have had a headache for the last four days. I did some research and found that ANTACIDS SHOULD NOT BE TAKEN WITHIN TWO HOURS OF DOXYCYCLINE!!! Bummer for me, since I have been drinking Mylanta like it was my only source of hydration.

I've been taking this medication for around 2 days and today I felt like I had heartburn even though I didn't eat anything that causes heartburn, also I had a headache. Has this happend to anyone else here?

bad headache, really bad soreness of throat, tiredness, dizziness, and some itching.

Day 6 after laying down after taking doxy. Difficult to swallow , eat or drink. Headache gone, but burning in throat intense. Feels like labor pains in the chest. Lots of saliva production in the mouth. Seeing GI Dr tomorrow. !st 2 Dr.s think its the doxy

After jsut 1 pill I had swollen hands, felt like head was swollen but it didin't look like it! Tremendously sore jaw and ears-like a very severe sinus infection. Intense head ache, felt like I was crawling out of my skin, fidgty-yet tired, severe muscle aches in upper body...This was after just one pill. I stopped and I was fine 24 hours later...none of the symptoms remained.

I was on Doxycyline for a rash around my nose. I had taken them for a few days, but only taking one pill instead of 2; mainly because I kept forgetting to take the second one at dinner.
Two nights ago, I took the second one and immediately felt like it was stuck in my esophagus. Two days later, I am still feeling the effects. It was so bad that I didn't eat or drink anything for a day ... even drinking water was painful. It wasn't until today that I realized what the reaction was from, I really thought I was having a heart attack. In addition to the major heart burn I had such a bad head ache. Not to mention I was eating yogurt every day to ward off the possibility of a yest infection; which this medication is also known to cause. I will NEVER take this medication again!

after taking for about a week of 100 mg of doxycyline, I had a severe headache that lasted for almost two days. I do not wish to take this drug again.

swelling on the face accompanied my redness. sensitivity to light and headache.

i only took 2 of the 8 tablets i was perscribed the following side effects occured;headache,very swollen lips and mouth,really hurt to swallow,upset stomach,fealing weak and very unwell , will advise anybody not to take these tablets!

Nausea, vomiting, headache, dizziness, acid stomach, dry mouth, dry throat, tight breathing.

I'm taking 200 mg doxycycline, twice a day. I'm 6 weeks into a 9 week regimen for suspected but unconfirmed lyme disease (no memory of tick bite and no positive tests), and in conjunction with permanent Ceftin 500 mg twice daily as a prophylactic against strep which triggered an apparent and ongoing Rheumatic Fever. (I think my doctor is more confused than I am.)

I've gotten nausea and acid stomach, but both of these are lessened if I drink a large glass of water with the doxycycline. 200 mg can be hard to keep down.

I vomited once but only after taking it with other medicines which my doctor assured me wouldn't interfere. So I spaced them apart by 2 hours and started eating some food prior to the doxycycline, and the result was no more nausea or vomiting, and a much easier time.

Headache & dizziness are reduced when I take the doxycycline with food, and then it seems not to hit me as fast or as hard, and so I tolerate it much better.

At first I thought the doxycylline was helping relieve some kind of bronchial infection, but it was actually just drying out my mucus membranes. Now I wake up early with dry mouth, dry throat, and even my lungs get dry which is causing mild difficulty breathing. The bronchitis I thought it was helping was actually not an infection but an autoimmune symptom of the Rheumatic Fever, and it wasn't really helping with that, it just made it drier. Now instead of coughing up fluid, I get this unproductive dry pain when I cough, and my cough sometimes tastes like blood. I feel the dry pain in my lungs all the time now. I'd rather have the fluid.

3 weeks left on this regimen, which seems like an eternity, but I'll try to stay the course since I want to rule out lyme disease. All these high-dose powerful antibiotics and doctors don't even know what I have. They don't seem to be helping me much.

I've been on doxycycline for two months now for adult acne. My acne got pretty severe, but has calmed down a lot due to the medication. Originally my doctor prescribed me minocycline, which is in the same family (tetracyclines), because of my hunger with the doxycycline. The minocycline gave me an incredibly bad migraine, the worst in my life. I was unstable, and dizzy. After doing research on the net and talking with the pharmacists I work with ( no, i'm not a pharmacist, i am just a tech) we agreed it was intracranial hypertension and that I needed to stop right away. Being on the doxycycline doesn't give me nearly the headache I had being on the minocycline. I found that when I take the doxycycline before bed OR if I am not upright at least at a 90 degree angle, my esophogus will begin to burn.. I usually fix that with drinking A LOT of cool water and it goes away. My doctor told me to take the doxy twice daily, but I find that taking it once daily does the trick for my acne, it just takes a little longer for it to clear up. I guess I'd rather my acne take longer to clear then to have all the side effects everyone else is having.... which I have experianced. But like I said I take it two hours before bed staying in an upright position with lot's of water at hand... and I'm completely fine.

Side effects from 100mg one a day for long term treatment of chronic sinus problem; after 7 days: profound fatigue, appearance of pink rash to both hands that burns, painful feet, headache, and a feeling that the heart was too tired to pump, feeling very cold despite warm weather.

Have been on Doxycycline 100 mg - 2 x day, for only 2 day's and feel terrible. Headache, joint's ache, severe diarrhea (dark watery squirts), stomach cramps, dizzy, nausea, and I am freezeing in 70 degree sunshine! This suck's. I thought med's were supposed to help you feel better! I think I prefer the illness over the cure.

I began taking this medication at 100mg twice daily for a sinus infection and have experienced negative side effects. I actually experienced side effects and then decided to check the side effect listings for the drug online and they defintly match. I have experienced extreme dehydration, nauseau, headache, disorientation, drowsiness, and stomach pain. I have not experienced vommitting but have felt close to it. I have also experienced a loss of appetite.

I started taking doxycycline just 9 days ago,I couldn't believe it when I read these posts..I am having alot of the same symptoms as the rest of you. I have been getting sick to my stomach, no matter if i take it with food or not...more so if i don't take it with food. I have ringing in my ears..icy/hot flashes, headache and my eyes hurt. I am not sure if this med is worth all these side effects. I am taking it for adult acne. I also noticed that my face is quite red and sore to touch.I will give this med a month or two and if i don't see considerable improvement, i will stop taking it. I feel miserable.

I'm taking doxycycline for acne on my chest...there isn't any on my face. I'm five days into it now and I feel terrible. I vomited this morning. Now my calves are starting to hurt, I'm dizzy, have severe nausea, slight headache, and I'm weak. I'm done with this drug. I've been on many antibiotics for at one time almost two years straight...I've never had a problem like this! I'd rather have my acne.

dizziness, fatique, headache, diarreha, vison changes. i went to the er and the doctor told me there was no way i was having a reaction to the antibotic but yet i didnt feel this way till a good 24 hours into taking it and the reverse reaction sheet said i could

I have been taking doxycycline 100mg once a day for 5 weeks, now i am suffring from headache tingly hands ,DROWSINESS AND DIZZINESS,spasmodic contractions in stomach and esophagus ,as i feel it,and cardiac arrhythmia as well as palpitation feelings and Dark circles under or around the eyes .by the way ,i was taking nystatin as candida prevention.

took over a month for mild acne until i started getting headaches and cloudiness in my head ( i felt out there) the headache i would get was this pain in the left side above my ear.. so i stopped taking the doxy-whatever.. for a few wks now i still have this pain, especially when i touched the spot, it just feels really tender. i had a headache yesterday, it felt like it was my sinuses.. well stupid me decided to try the medicine out again today and a few hrs later what happens?.. i started to feel light-headed.. i called the doctor he told me to stop using it and i am seeing him on tues.. he also told me that the medicine shouldnt be giving these side effects.. so to tell you the truth everyone acts differently to medicines..
i am soo done with this medicine!! especially after reading everyone's comments.. im going to look into accutane which i heard works really well. hopefully i wont have any more problems!

I have taken Doxy several times now and usually end up discontinuing use because of strange side effects. Once because of intense burning of my skin (lasted several days). Another time because of disorientation and headache. Now I am taking it for a sinus infection. Giving it one last shot. I have only taken two doses, one last night and one this morning; and I am already extremely nauseous and lightheaded. My doctor told me if I dont finish this, my infection may turn into pnuemonia. I guess i will suffer through it.
