Over-the-counter migraine medications used to address pain include analgesics, NSAIDS, and caffeine, including: 1  Aspirin. 2  Naproxen (Naprosyn, Anaprox, Anaprox DS) 3  Ibuprofen (Motrin)  Acetaminophen 1  (Tylenol) Or combinations of these.
Two beta blockers are currently FDA approved for use in the preventative treatment of migraine: propranolol (Inderal and Inderal LA) and timolol (Blocadren). Three other beta blockers are also used, although these drugs are not approved by the FDA for indication in migraine. These three agents are: atenolol (Tenormin), metoprolol (Lopressor), and nadalol (Corgard). Blockade of these beta adrenergic receptors results in inhibition of arterial dilatation.
