What NAPAMIDE is used for

NAPAMIDE tablets are used to treat mild to moderate hypertension (high blood pressure).

NAPAMIDE allows the heart muscle and surrounding bloods vessels to relax more fully and hence carry the same volume of blood more easily. It can be used alone or in combination with other medicines to lower blood pressure.

Your doctor, however, may prescribe NAPAMIDE tablets for another purpose. Ask your doctor if you have any questions about why NAPAMIDE Tablets have been prescribed for you.

This medicine is only available with a doctor's prescription.
