migraine
"I've had migraines for 40 years. This works 9 out of 10 times, usually in about 20 minutes. Occasionally I've had to take a second pill or dose, but 1 pill almost always does the trick. The other 10 % of the times I use Maxalt or its generic form. My insurance has recently dropped coverage for this inexpensive, very effective drug.  I'm not happy and plan to appeal for coverage."
