Alopecia and drug eruption of the scalp associated with a new beta-blocker, nadolol.

In 1985, a case was reported where a patient developed infiltrative dermatitis and significant alopecia (hair loss) of the scalp after being prescribed a new beta-blocker, nadolol, for hypertension. After four months of therapy, the beta-blocker was discontinued, leading to a dramatic reduction of the skin eruption and total regrowth of scalp hair within three months. This case was unique as the rapid hair regrowth upon discontinuation of nadolol distinguished this type of alopecia from the telogen effluvium previously associated with other beta-blocker drugs, such as propranolol and metoprolol.
