Why is this medication prescribed?

Isoptin, also known as verapamil, is prescribed for several medical conditions, including:

  • Hypertension (High Blood Pressure): Isoptin is commonly used to treat hypertension by relaxing and widening the blood vessels, which helps to lower blood pressure and reduce the workload on the heart.
  • Angina Pectoris: Angina is a type of chest pain that occurs when the heart muscle doesn’t receive enough oxygen due to narrowed or blocked coronary arteries. Isoptin is prescribed to relieve and prevent angina attacks by improving blood flow to the heart muscle.
  • Arrhythmias: Isoptin is effective in treating certain types of abnormal heart rhythms, such as atrial fibrillation, atrial flutter, and supraventricular tachycardia. It works by slowing down the electrical signals in the heart, thereby restoring a normal heart rhythm.
  • Migraine Prevention: In some cases, Isoptin may be prescribed as a preventive treatment for migraines. It is believed to work by reducing the frequency and severity of migraine headaches.
  • Raynaud’s Phenomenon: Isoptin is sometimes used to manage Raynaud’s phenomenon, a condition characterized by spasms in the blood vessels of the fingers and toes, leading to reduced blood flow and discoloration. By dilating the blood vessels, Isoptin can help improve circulation and alleviate symptoms.

It’s important to note that Isoptin should only be used as prescribed by a healthcare professional. The specific dosage and duration of treatment will depend on the individual’s medical condition and response to the medication. Always consult with a doctor or pharmacist for personalized advice and guidance regarding the use of Isoptin.

It is important to follow the prescribed schedule and take the medication at the same time(s) each day.
