Migraine medications overview

Migraine is a serious, potentially life-threatening neurological disease that affects nearly 32 million Americans, the majority of whom are women. The hallmark symptom of migraine is an escalating, often unbearable, debilitating headache that is commonly described as intense throbbing or pulsating pain in one area of the head. The pain may be accompanied by extreme sensitivity to light and sound, nausea, and vomiting. In some people, migraines are preceded by visual disturbances known as auras that may include flashing lights, zigzag lines, or temporary blindness.

OVERDOSE

Propranolol is not significantly dialyzable. In the event of overdose or exaggerated response, the following measures should be employed:

Hypotension and bradycardia have been reported following propranolol overdose and should be treated appropriately. Glucagon can exert potent inotropic and chronotropic effects and may be particularly useful for the treatment of hypotension or depressed myocardial function after a propranolol overdose. Glucagon should be administered as 50-150 mcg/kg intravenously followed by continuous drip of 1-5 mg/hour for positive chronotropic effect. Isoproterenol, dopamine, or phosphodiesterase inhibitors may also be useful. Epinephrine, however, may provoke uncontrolled hypertension. Bradycardia can be treated with atropine or isoproterenol. Serious bradycardia may require temporary cardiac pacing.

The electrocardiogram, pulse, blood pressure, neurobehavioral status and intake and output balance must be monitored. Isoproterenol and aminophylline may be useful for bronchospasm.

CONTRAINDICATIONS

Propranolol is contraindicated in 1) cardiogenic shock; 2) sinus bradycardia and greater than first-degree block; 3) bronchial asthma; and 4) in patients with known hypersensitivity to propranolol hydrochloride.
