What is a generic medication?

Generic medications are significantly discounted copies of brand name medication that have the same active ingredients, intended use, dosage, side effects, effects, and route of administration as the original brand name medication. In other words, generic medications have the same pharmacological effects as their brand-name counterparts. Over half of all prescribed medications are for generic medications.

  • Calan Overview

    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 is also used to prevent chest pain (angina). It may help to increase your ability to exercise and decrease how often you may get angina attacks. Verapamil is also used to control your heart rate if you have a fast/irregular heartbeat (such as atrial fibrillation). It helps to lower the heart rate, helping you to feel more comfortable and increase your ability to exercise.

  • How to Use Calan

    Take Calan by mouth with or without food as directed by your doctor, usually 3 or 4 times daily. The Dosage of Calan is based on your medical condition and response to treatment. Use Calan regularly to get the most benefit from it. To help you remember, take it at the same times each day. For the treatment of high blood pressure, it may take a week before you get the full benefit of Calan. Keep taking Calan 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 Calan regularly as prescribed. Calan should not be used to treat chest pain when it occurs. Use other medications to relieve sudden attacks as directed by your doctor (for example, nitroglycerin tablets placed under the tongue). Consult your doctor or pharmacist for details. Do not stop taking Calan without consulting your doctor. Some conditions may become worse when Calan 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).
