Treat SSRI induced delayed ejaculation. I have also tried it many years ago, based on the literature, for migraine prevention and cyclic vomiting syndrome with dubious efficacy. Reading up on it today, I also see that it has been used off-label for psychogenic itch and drug-induced akathisia and hyperhidrosis. It is also used as an appetite stimulant.Doxepin is an antidepressant with anticholinergic properties. I use it occasionally as a sleep aid and for chronic urticaria, because the modern nonsedating antihistamines are less effective for itching. It is the anticholinergic effect that relieves itching, and the more famous diphenhydramine (Benadryl) is too short acting to be very practical for chronic itching.Misoprostol is one of the few medications that can help tinnitus.

Misoprostol is only approved as a stomach protectant for people who take NSAIDs like ibuprofen, and to induce abortions, start labor or control postpartum hemorrhage. Why it sometimes works for tinnitus is a mystery to me.Off-label use of a whole host of medications is so common that we almost forget that the FDA hasn’t caught up yet, but of course, the FDA will only “approve” an indication after it has been presented with sufficient evidence (at great cost to somebody). Who will do testing on old, generic and inexpensive drugs if there is no money to be made from the new indication?Very rarely does a drug company bring evidence to the FDA about the safety and efficacy of an old drug. This happened some years ago with the ancient drug colchicine for gout. One manufacturer produced the required evidence and got a patent, and the new brand name Colcrys. Now that patent has expired and, ironically, now there is another indication, still off-label, we all use: It is very effective for painful pericarditis. But who will spend the money to get it “approved”?Medicine is an art, and use of medications is one of the expressions of this. There are two ways of looking at off-label prescribing. You can
