Doxycycline Hyclate and twice daily

I was prescribed Doxycycline by the Student Health Center at my college for alleged Bronchitis. I've been taking 100mg twice daily, and I definitely noticed the intense nausea immediately. I've always had a strong stomach, so I was a bit surprised by how I reacted to it. Luckily no vomiting. But within 2 days, I noticed that my vaginal area was incredibly irritated, itchy, and red. I thought it was just random irritation, but it has persisted for three days, and I finally realized it wasn't a temporary thing. I've never had a yeast infection before, so I spent an afternoon researching them, and was terrified that it was a symptom of an STD (even though I'm well educated on the subject).

In my research, I somehow stumbled upon the name of this drug, and immediately searched for further side effects (since my doctor only told me to take water and food with it, avoid sunlight, and not to lie down within 1/2 an hour of taking it). What do you know, but yay yeast infections.

Basically, I'm furious with my practitioner for not warning me about all of the things I've read on this site. I've stopped taking the medicine and have no problem with dealing with a cough if it means the yeast infection goes away. I'm never taking this drug again.

I am also currently taking doxycyline as a preventative measure because my boyfriend had NGU. I am taking 100mg twice daily. I experienced very mild nausea, I felt very bloated and had extreme gas. You just feel very heavy when taking this medication. I felt full all the time and my stomache was semi hard and when I put pressure on it, it caused burping and farting... sorry to be so graphic :)

I took 100mg of Doxycycline twice daily for suspected Epididymitis. The first few days I followed the instuctions and didn't notice any side effects. One night though I woke up with incredibly painful heartburn. I think I may have taken the pill without enough water right before bed. After that I continued to take the pills and the side effects started to become worse. I had headaches, dizziness, loss of appeitite, and painful heartburn. My advice to anyone taking this medicine would be to follow the instructions and not take the pill right before sleeping. It has been two days since I stopped taking Doxycycline and the side effects still have not subsided.

My teenage daughter has been taking Doxycycline 100mg twice daily for about 2 weeks now. Today we spent the day on the beach. She is experiencing tingling in her hands, arms, feet, and lips. She was also experiencing burning sensations with her arms, lips, face, and feet. Now that she is inside and out of the sun the burning sensation has subsided. The tingling remains.

day 4 of taking 100 mg twice daily for a bronchial problem, rash over torso with slight itching, but severe unrelenting itching and burning on the palm of my hands.

I have been prescribed Doxycycline 100mg twice daily for suspected Lyme disease. I have never experienced such strong side effects from taking an antibiotic before! The morning dose is the worst by far for me. It makes me feel incredibly nauseous and it makes me feel hot with stomach pains. I feel like being sick all the time for about 3-4 hours after taking it - I have tried lots of water and food but I still feel like crap! After about 4 hours I start to feel a little better then I feel like eating lots and lots!!! My body just seems to be swinging from feeling like I am dying to being very hungry hours later... I take the last pill about 10pm and stay downstairs for about a hour before I go to bed - strangely enough though I have never felt ill like I do in the morning and go to sleep ok. All very weird and I cant wait until I have finished taking this drug (14 day course and I am half way through)

I started taking Doxycycline five days ago for adult acne (I'm 30 and experiencing hormonal side effects from coming off DepoProvera after one year). I was prescribed 100 mg twice daily. My evening pill is okay, I take it right before bed. But when I take the pill in the morning, I get absolutely nauseous for about thirty minutes after and it feels as though I swallowed a pill ten times its actual size and it's still stuck in my throat. I haven't thrown up yet, but I've been up to that point for thirty minutes at a time. I'm weighing the benefits and side effects in considering whether or not to continue taking it. I haven't had the nauseau every time I've taken the pill, so I'm trying to drink water and eat to see if that helps. I'm thinking these side effects may subside over time.

Everyone's suggestions were really helpful to me so I wanted to post mine in hopes they will help someone else.

I just started taking doxycycline for possible lyme's 100mg twice daily. I have to say I can't believe some of the things I'm reading here. It honestly makes me want to stop taking it. My doctor prescribed it for 21 days. I'm going away on vacation 15 days into taking this medication. Does anyone think it would be ok to stop this on the 15th day vs taking it til the 21st day. I really really don't want to have any problems while on vacation. Your help would be appreciated. Thanks

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.

started taking Doxycycline for MRSA Staph infection. 2nd time having. Given along with Bactriban ointment for the nose. 1st time had, was prescribed Septra (trimethoprim and sulfamethoxazole). Seemed to work, but disappointed when reappeared. Doc. thought Doxy would be more effective. Stomach burning like acid reflux. Relief some when only lite meal, like rice. Doctor prescribed 2 pills twice daily to start... had me vomiting and dizzy. Then settled to 1 pill twice daily. Stomach pain definite issue with this drug!

My doctor prescribed doxycycline for stage one of lyme disease just a few days back. Since taking the medication, (100mg twice daily), I have experienced nausea.. most prominent with the morning dose. What surprised me most was when I read the e-mail from another individual who noted that they feel cold all the time, although the temperature outside is warm. Prior to taking the doxycycline, I was running a low temp of just over 100. My temperatures are back to the more normal range now but, I have been freezing and wondering what has been going on!! Perhaps, yet another side effect of doxycycline????

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.

Experienced very mild nausea, flatulence, and felt very bloated. Taking 100mg twice daily to discourage infection.

started taking this 2 days ago and had nothing but a darn migrian to the point the bright lights almost made me feel the need to vomit..im taking 20MG twice daily for acne.

I started taking this med for treatment of acne. Doxycycline 100 MG twice daily. Within 4 days, I started experiencing chest pain, arm and back pain, palpitations, dizzieness, weakness in the legs and arms, diarrea, pain in the eyelids. I thought i was dying! I followed all of the instructions from the pharmacist and the doctor, and it still happened. They tried to tell me it was a problem with anxiety since it runs in my family. After finding this site, i think differently. I think anxiety might be a part of it, but not what caused it, i will never take tetracycline based products again, and will never recommend them to anyone.

I started taking DOXY 100 Mg twice daily for MILD cystic acne, together with a DUAC Gel in the morning. I took the first pill with a little food, but no dairy, and felt a little loopy. I noticed myself getting severly dehydrated also, and had to slam a lot of water (like 32-44 oz.) I took the second dose at around 5pm; by 11:00 PM I was experiencing a severe pain in my head just above and behind my left ear. I guess it could be considered a skin pain, but it feels deep; putting my sunglasses on sparked it up this morning. The pain is very acute and comes in waves of 10 -12, 10-15 second shooting pains in each wave. I discontinued the meds after seeing some of the similar "nerve pain" postings here and will advise my doctor on Monday.

I'm using this to be treated for bilateral polycystic ovaries, inflammed fallopian tubes, minimal fluid, and pelvic infection (caused by muscle cramps or spasms). =) On Doxycycline, I experience severe chest pressure, nausea, headache, trouble swallowing, and more frequent urination from twice daily usage.
Glad to know I'm not alone!
