Honey... these aren't normal migraines. You've had a brain injury. PLEASE follow your neurologist's orders to the letter. Do NOT play around when it comes to your brain. Don't question strangers... question doctors who specialize in head trauma.

To know: IGNORE what meds are labeled as "for" (Viagra, for a famous example was a heart med. Only because of it's *incredible* success "off label" did the drug company find that spending the hundreds of millions of dollars it takes to "relabel".) Here's how drugs work... companies spend billions developing, testing, certifying them. Unlike most things, marketing is just a drop in the bucket where meds are concerned. If, in the R&D process, a company develops a drug that works for both depression and as an antipsychotic... they look at what patents they already own. If the already own a bestselling antidepressant, they get it certified (labeled) as an antipsychotic. Now the drug could be a lousy antipsychotic, but a better antidepressant than prozac - but if the company already owns prozac - they get it labeled as an antipsychotic. Same token, Psychiatrists will notice that while Rx'ing the drug as an antipsychotic that it doesn't work that well BUT it works great as an antidepressant. So they start Rx'ing it as an antidepressant. OR they may find it is the BEST antipsychotic in the world when paired with a 2nd drug. If that combo becomes standard AND the same drug company owns the rights to both, they may even start pressing pills that are standard doses of both drugs. But WAIT... in the whole process of patients using it... the drug ALSO is found to work on incontinence. Guess what? That "antipsychotic" will now also be prescribed as:
- an antipsychotic
- an antidepressant
- for patients with bladder problems
Why don't drug companies add the other "off label" things onto the label? They have no need to. Word gets out through word of mouth, medical publications, conferences, and their own drug reps. There is absolutely NO need for the drug company to spend another couple hundred million to add 2 more "uses". It already gets used for them, because docs spend a LOT of time reading up on meds, because new discoveries (good and bad) are made every day. As a matter of fact, lists go out weekly as to what's going on with meds in every specialty. It's so complex (thousands of meds) that there is NO way that a single doctor can stay caught up on every med in every specialty. So neurologists stay caught up on meds in their field, cardiologists on meds in theirs, urologists in theirs, psychiatrists in theirs, thoracic surgeons in theirs, anesthesiologists in theirs, OB/GYNs in theirs... the list goes on... and general practitioners leave the detail work to the specialists and just pay attention to the whole sweeping picture (kinda like how we the public don't know every minute of every bit of news in Washington, because reporters pick the most newsworthy to print/broadcast).
