Isoptin is a medication that contains the active ingredient verapamil hydrochloride. It is primarily used to treat high blood pressure (hypertension) and angina (chest pain).

Isoptin belongs to a class of drugs called calcium channel blockers, which work by blocking calcium channels in the heart and blood vessels.

Follow the instructions provided by your healthcare provider and do not exceed the prescribed dosage.

It is advisable to consult with a healthcare professional or pharmacist for personalized advice and more detailed information specific to your situation.

Use and Dosage

Take this medication by mouth with or without food as directed by your doctor, usually 3 or 4 times daily.

The dosage is based on your medical condition and response to treatment.

Use this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day.

For the treatment of high blood pressure, it may take a week before you get the full benefit of this drug. Keep taking this medication even if you feel well. Most people with high blood pressure do not feel sick.

To prevent chest pain, it is very important to take this medication regularly as prescribed. This drug should not be used to treat chest pain when it occurs.

Do not stop taking this medication without consulting your doctor. Some conditions may become worse when this drug is suddenly stopped. Your dose may need to be gradually decreased.

Tell your doctor if your condition does not get better or if it gets worse (for example, your blood pressure readings remain high or increase or your chest pain occurs more often).
