Betaxolol (ophthalmic)
Summary
What conditions betaxolol is used for
Betaxolol is used to treat high blood pressure, which is called hypertension, and certain heart conditions like angina, which is chest pain caused by reduced blood flow to the heart. It helps lower blood pressure and reduce the heart's workload by blocking specific receptors in the heart.
How betaxolol works in the body
Betaxolol works by blocking beta-adrenergic receptors in the heart, which helps lower blood pressure and reduce the heart's workload. This action reduces the effects of adrenaline, which is a hormone that increases heart rate and blood pressure, helping manage hypertension and certain heart conditions.
Directions for Use
The usual starting dose of betaxolol for adults is 10 mg once daily, taken orally. Your doctor may adjust the dose based on your response and needs, with a maximum recommended dose of 20 mg per day. Betaxolol is not typically used in children.
The most commonly observed adverse effects of betaxolol
Common side effects of betaxolol include dizziness, fatigue, and a slow heart rate, which is called bradycardia. These effects are usually mild and may improve as your body adjusts to the medication. If you experience new symptoms, talk with your doctor.
Warnings and Precautions
Betaxolol can cause a slow heart rate, which is called bradycardia, and low blood pressure, which is called hypotension. It is contraindicated in people with severe heart block, which is a condition where the heart's electrical signals are delayed or blocked, and in those with severe bradycardia.
