The onset of action for Verapamil ER can vary depending on the specific condition being treated and individual patient factors. For hypertension and angina, a clinical response may be observed within the first 24 hours after initiating therapy, with maximum effects typically seen within 1 to 2 weeks of consistent use.

How long do the effects of this medicine last?

The effects of Verapamil ER last approximately 24 hours due to its extended-release formulation, supporting its use as a once-daily medication. The consistent plasma levels achieved with the ER formulation help maintain therapeutic effects over this period.

Is it safe to consume alcohol while taking this medicine?

Consuming alcohol while taking Verapamil ER may enhance the blood pressure-lowering effects of the medication and increase the risk of side effects such as dizziness, lightheadedness, and fainting. Patients are generally advised to moderate their alcohol consumption while on Verapamil ER.

Is this a habit forming medicine?

Verapamil ER is not habit-forming and does not have the potential for abuse or dependence. It is used for its cardiovascular effects rather than any psychoactive effects.

Can this medicine be taken during pregnancy?

Verapamil ER is classified as FDA Pregnancy Category C. Animal studies have shown an adverse effect on the fetus, and there are no adequate and well-controlled studies in humans. However, the potential benefits may warrant the use of Verapamil ER during pregnancy despite potential risks. It should be used during pregnancy only if clearly needed and under the guidance of a healthcare provider.

Can this medicine be taken while breast-feeding?

Verapamil is excreted into breast milk in small amounts. While there have been no reported adverse effects on nursing infants, the decision to continue breastfeeding while taking Verapamil ER should be made after considering the importance of the medication to the mother's health and the potential for side effects in the nursing infant. Consultation with a healthcare provider is recommended to weigh the risks and benefits.

Uses

Verapamil is used to treat high blood pressure. Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. Verapamil belongs to a class of drugs known as calcium channel blockers. It works by relaxing blood vessels so blood can flow more easily. Verapamil may also lower your heart rate.
