Doxycycline Hyclate and eye infection

I have a severe eye infection going on 2 years+ Combo dry eye,blepratis etc.my eye glands are all stopped up!
Vanderbilt Eye Dr. Put me on this for 90 days, plus antibotic drops,
warm compresses, systane drops, I'm afraid of the side effects,
been on it 1 day, 100mg twice daily. I'm on Zyban for depression,Zyrtec for allergies, BP meds so
hopefully it won't effect me. I feel hyper,but seem un-able to focus.
Any help, other people with eye problems, please e-mail me.
Thanks, Sue

Not sure if its Hyclate or not, but I am taking Doxycycline for an eye infection (100mg 2x/day). At first everything was ok, then after about 4 days, I stated having some nausea and acid reflux (throat seemed to be burning). I have to take it for 3 more weeks, but next week only 100mg/day which I hope will help.\
Is this typical of an antibiotic that you might not get any side effects until it build up in your system?

I was prescribed Doxy 100mg 2x a day for a sinus/eye infection 2 years ago after sinus surgery. It upset my stomach so bad but my doctor said to keep taking it because the stomach upset was less problem then this infection. I also got a yeast infection. Didn't have to deal with the sun because it was winter in the midwest. My stomach never returned to normal. Now I am labeled having IBSD. I have very frequent diahrhea on & off. It seems go into remission every now & then. I have had an upper & lower GI too. Nothing was found. Now 2 years later I get another sinus/eye infection. Doc gives me again. I forgot this was the same drug I had 2 years ago until I called my old pharmacy and had them check my records. This time I only took one pill after eating. I took it at 6:30pm. At 1am I woke up with a burning pain in my chest. I was sweating so badly. I got up and ate some soda crackers. I didn't feel nauseaus, just burning pain like heartburn. I finally got back to sleep at 3:30am. Woke up at 11am.

I remembered what the doc said 2 years ago and decided to take another dose. With food of course. About 4 hours later I was in the bathroom bent over in pain with the runs severely. I called the doctor. Being it was Saturday and after hours I got the oncall doctor who wasn't very sympathetic. All her heard was CHEST pain and ordered me to go to the hospital ER. I argued abit with him and he just yelled back "Go to the ER now." Being the stubborn person I am, I did not go. But I did not take another dose. I called the pharmacy the next day and told them what happened. They said it was definitly a drug reaction. I am going to call my doctor tomorrow and demand a different med. This stuff should be banned.

Doxycycline has prescribed to me has an antibiotic for my eye infection, but after a dose, i felt a buring sensation on my chest, followed by a sharp pain in my chest. Hurts when swallow food and drink, lost appetite as a result
