Are there any known side effects with taking minomycin?
All drugs have known side effects, including minocycline (minomycin). Some of the most common are photosensitivity and GI upset, but it’s possible with this or any antibiotic to wind up with a C. difficile superinfection and a life-threatening diarrhea. That’s the reason the warning label says to call your doctor in case of diarrhea, as in the Wikipedia quote posted above. Also, as noted above, an allergic reaction is always possible, though they are not common with tetracyclines. The side effects aren’t guaranteed, obviously. Millions of people use this drug for acne and don’t experience any side effects. I recently found out my daughter, who’s taking this antibiotic, has been tanning regularly – against doctor’s orders – but hasn’t had any ill effects.
