Doxycycline

I'm currently taking doxycycline for Lyme disease, and about a week into my month prescription, I started having severe itching all over my body. It keeps me up at night, and when I asked if there was anything else I could switch to, I was told that doxycycline is basically the only choice for Lyme disease...sigh.

I am 11 days into a 20 day regime of Doxycycline for Staph. I am 51 and have not had a period in 2 years. 2 days ago I had some breast tenderness and this morning I woke to classic menstrual bleeding with abdominal cramps.

Could the Doxycycline be responsible for this in some way? Should I follow up with my GP or call my GYN?

i had these 100mg tablets for a sinus infection its gone now i take the last 1 tomorrow but after the few few days on them i ad to take 8 2 to start with then 1 a day. so after a few days on them i got 2 complaints my anus was a bit sore and neck and shoulder pain stiffness so ill be glad to get the last 1 took now tomorrow.

I took doxycycline for 10 days for perioral dermatitis. A week after completing the medicine I went to the ER with a burning in my chest. Then I lost my appetite, was nauseous and started losing weight. Three weeks later I was diagnosed with gastroparesis. I went on motility medication and changed my diet. It has been 14 months, I am improved, no longer taking the medication and able to eat small meals that are easily digestible. I know of 4 other people who developed gastroparesis after taking doxycycline.

I am a 45 year old women who developed acne 4 years agao after my hysterectomy.I have been using doxycycline for the last 10 months......the only side effects I have experienced are nausea if pill tkn in empty stomach and weight gain ( which could be just my age). I took myself off the pills for 3 weeks, but my acne returned worse than ever!!! I have started taking it again...with in 3 day sthere was a marked improvement. Clearly I will continue taking it......what are the effects of taking this drug over long periods of time? Can any one help me on this?

I have just taken myself off Doxycycline.  I had so much pressure in my skull - unable to stand for very long, felt really weak and thought I was going to pass out..A Few pains in my kidney area.

I was taking them as an anti-malarial. Caused a duodenal ulcer and a bleed on the brain, either of which could have killed me. Both nearly did, I had 3 months in hospital and 8 operations before I was discharged. I will probably never be properly well again.

The doctor had prescribed me 100 mg doxycycline twice daily for 14 days. On 9th day of medication, I had itching in different parts of my body. Then I consulted the doctor but he asked me to continue the doxycycline and complete the course. To control itching he gave me antihistaminic drug for the remaining medication period. Even after completing the course of medicine I had little bit itching for one more week.
