Verelan

Verelan is a prescription medication used to treat high blood pressure. Verelan belongs to a group of drugs called calcium channel blockers, which work by relaxing the blood vessels, making it easier for the heart to pump blood.

Verelan comes as an extended-release capsule form and is usually taken once day with or without food.

Common side effects of Verelan include constipation, nausea, low blood pressure, and headache. This medication can also cause dizziness. Do not drive or operate heavy machinery until you know how Verelan affects you.

Verapamil is a prescription medication used to treat chest pain, an irregular heartbeat, and high blood pressure. The extended- and sustained-release forms are used to treat high blood pressure.

These medications may be prescribed for other uses. Ask your doctor or pharmacist for more information.

Tell your doctor if you are pregnant or plan to become pregnant.

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.

Verapamil falls into category C. There are no well-controlled studies that have been done in pregnant women. Verapamil should be used during pregnancy only if the possible benefit outweighs the possible risk to the unborn baby.

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

This medication is excreted in human milk. Because of the potential for adverse reactions in nursing infants from verapamil, nursing should be stopped while verapamil is being taken.
