Prinzide

Prinzide is a prescription medication used to treat high blood pressure. It is a single product containing 2 medications: lisinopril and hydrochlorothiazide. Lisinopril belongs to a group of drugs called angiotensin-converting enzyme (ACE) inhibitors. Lisinopril works by blocking the ACE enzyme, which helps blood vessels to relax and lowers blood pressure. Hydrochlorothiazide belongs to a group of drugs called thiazide diuretics, which work by stopping reabsorption of salt into your body. This prevents fluid from building up in the body.

This medication comes in tablet form and is taken once daily, with or without food.

Common side effects include dizziness, headache, and cough. 

Prinzide can cause drowsiness and dizziness. Do not drive or operate heavy machinery until you know how Prinzide affects you.

The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.

Prinzide falls into category C in the first trimester and category D in the second and third trimester. When pregnancy is detected, discontinue Prinzide as soon as possible. Drugs that act directly on the renin-angiotensin system can cause injury and death to the unborn baby.

Tell your doctor is you are breastfeeding or plan to breastfeed. 

It is not known if lisinopril, a component of Prinzide, is excreted in human breast milk. Hydrochlorothiazide, the other component of Prinzide, has been detected in human breast milk. Because of the possibility for adverse reactions in nursing infants from Prinzide, a choice should be made whether to stop nursing or to stop use of this medication. The importance of the drug to the mother should be considered.
