General

Betaxolol (the active ingredient contained in Kerlone) is generally well-tolerated. In one large study of 4,685 patients, only 14% experienced side effects after six months of therapy.

Nervous system

Nervous system side effects include headache in 15% of patients, although headache has been more common in patients treated with placebo in controlled studies. Fatigue or dizziness are reported in 10% to 16% of patients. Five percent of patients complain of insomnia. Rare side effects include vertigo, paresthesias, lethargy, depression, nervousness, nightmares, and dizziness.

In one study of 317 evaluable patients with hypertension, no side effects associated with betaxolol were more common than with placebo.

Cardiovascular

Cardiovascular problems include dose-related bradycardia 1% to 8% and Raynaud's phenomenon in 3% of patients. Bradycardia may be more likely in elderly patients. Edema or palpitations occur in 2% to 5% of patients. No reports of congestive heart failure (CHF) associated with betaxolol (the active ingredient contained in Kerlone) have been reported, although new or worsened CHF has been associated with the use of some other beta-blockers.
