Verapamil, also known as Calan, is a medication that is primarily used to treat high blood pressure and heart disease. It belongs to a class of drugs called calcium channel blockers, which work by relaxing the blood vessels and reducing the workload on the heart. In this comprehensive guide, we'll explore the uses, dosage, and potential side effects of Verapamil, as well as important information on drug interactions and precautions to take when using this medication.
What is Verapamil used for?.
Verapamil is primarily used to treat high blood pressure, angina (chest pain), and certain heart rhythm disorders such as atrial fibrillation. It can also be used to prevent migraines and cluster headaches. Verapamil works by relaxing the blood vessels, which allows the blood to flow more easily through the body. This reduces the workload on the heart and can help to lower blood pressure.
How does Verapamil work?.
Verapamil works by blocking the entry of calcium into the cells of the heart and blood vessels. Calcium is essential for the contraction of the heart muscle and the narrowing of blood vessels. By blocking the entry of calcium, Verapamil reduces the workload on the heart and allows the blood vessels to relax, which can help to lower blood pressure and reduce the risk of angina and heart rhythm disorders.
Types of Verapamil.
Verapamil is available in two forms: immediate-release and extended-release. Immediate-release Verapamil is typically taken two to four times a day, while extended-release Verapamil is taken once a day. The extended-release form is designed to release the medication slowly over a 24-hour period, which can help to maintain a more consistent level of medication in the blood.
Dosage and administration of Verapamil.
The dosage of Verapamil will depend on the condition being treated, the patient's age and weight, and other medical factors. It is important to follow the dosage instructions provided by your healthcare provider and to not take more or less of the medication than prescribed. Verapamil can be taken with or without food, but it is important to take it at the same time(s) each day to maintain a consistent level of medication in the blood.
Common side effects of Verapamil.
Like all medications, Verapamil can cause side effects. Some common side effects of Verapamil include dizziness, headache, constipation, nausea, and fatigue. These side effects are typically mild and go away on their own as the body adjusts to the medication. If you experience any of these side effects and they are persistent or bothersome, contact your healthcare provider.
Serious side effects of Verapamil.
While rare, Verapamil can also cause serious side effects. These include low blood pressure, slow heart rate, heart failure, liver problems, and allergic reactions. If you experience any of these symptoms, seek medical attention immediately.
Precautions and contraindications for Verapamil.
Verapamil should not be used by patients with certain medical conditions, such as severe heart failure, low blood pressure, or certain heart rhythm disorders. It may also interact with other medications, so it is important to inform your healthcare provider of all medications you are taking. Verapamil should not be used during pregnancy unless specifically directed by a healthcare provider.
