“Doxy” is an antibiotic pill that is often used in the treatment of blepharitis.  With blepharitis (chronic eyelid irritation) one of the causes of eye irritation is from poor oil flow from the meibomian glands that run along the edge of the eyelids.  Doxycycline has been found to help oil flow throughout the body, and this may help with the eye irritation.  In fact, doxycycline is used for people with rosacea or acne because of a similar mechanism. This medicine shouldn’t be used in children or when there is any potential for pregnancy. Also, it may interact with dairy products, and patients have an increased risk of sunburn while on it.
