Propranolol is a beta blocker medication which is helpful in preventing migraine attacks in some patients. If a patient is having frequent attacks or severe, long-lasting attacks, it may be of help in cutting down the frequency of the attacks. However, it should be taken only under the careful supervision of a physician familiar with its use.
A dose of propranolol up to 240 mg may be necessary. Inderal LA (60-80-120-160 mg) is a convenient one-a-day way to take the medicine.
Inderal® can diminish endurance and tolerance to running and exercise, and it may take longer to accomplish previous goals. Immediate side effects can include diarrhea, tiredness, slowed pulse, and/or lowered blood pressure. These side effects are sometimes transient. Patients with bronchial asthma or other similar lung conditions, congestive heart failure or heart block should not use this agent. Do not stop this class of medication abruptly as it can cause problems with heart rhythm in sensitive individuals.
