The beta blockers--propranolol (Inderal), metoprolol (Lopressor), nadolol (Corgard), timolol (
Blocadren), atenolol (Tenormin), pindolol (Visken), or acebutolol (Sectral)--may cause insomnia, cold hands and feet, tiredness or depression, a slow heartbeat or may bring on symptoms of asthma.
Propranolol hydrochloride (Betachron E-R, Inderal), timolol maleate (
Blocadren), and nadolol (Corgard), all of which lack intrinsic sympathomimetic activity, are recognized as effective migraine prophylactic agents.
Those products, and their Merck counterparts, are: methyldopa (Aldomet), methyldopa and hydrochlorothiazide (Aldoril), timolol maleate (
Blocadren), chlorothiazide (Diuril), and amiloride HC1 and hydrochlorothiazide (Moduretic), all for treating high blood pressure; sulindac (Clinoril) and indomethacin (Indocin), both for treating arthritis; and cyclobenzaprine HC1 (Flexeril), for treating muscle spasms.
