I am bumping this thread yet again.
Wondering if anyone can give some perspective on long term (6 months) use of doxyclycline. I know it is used that long as a prophylaxis against malarial, but I have been prescribed it for another issue. I have only been on it a week, and I seem to be tolerating it well, but I am concerned about what the effects of using an antibiotic for so long might be. I know it can cause sun sensitivity, for instance. What should I be on the lookout for and at what point should I worry? My doctor is at the moment not getting back to me about these questions.
Again, just looking for advice and thoughts. I won't sue.
Sun sensitivity is the big one. It also causes nausea/vomiting in some people, but this is one of those effects that you'll figure out quickly (it's not a delayed reaction), so if you have that, you'll want to talk to your physician about switching to something else.
If anything more severe happens - hives, difficulty breathing, rashes, eyes or skin turning yellow, unexplained pain (especially in the chest or abdomen), diarrhea, etc. - then call your physician ASAP.
I hope that helps, CBS!
