Table of contents:

Adalat XL is a medication used to treat high blood pressure and angina (chest pain) caused by coronary artery disease. It contains the active ingredient nifedipine, which belongs to the class of medications called calcium channel blockers.

Adalat XL works by relaxing the blood vessels, allowing blood to flow more easily, and reducing blood pressure. Adalat XL is an extended-release tablet that is designed to release the medication slowly over a period. It is taken once a day, usually at the same time each day.

Use and Dosage

Adalat XL comes in the form of extended-release tablets that are designed to release the medication nifedipine slowly over a period. Adalat XL should be taken exactly as prescribed by your doctor. It is usually taken once a day, with or without food. Swallow the tablet whole with water and do not crush or chew it.

The recommended doses of Adalat XL (nifedipine extended-release tablets) may vary depending on the condition being treated and other individual factors. The recommended starting dose for hypertension or angina is 30 or 60 mg taken once daily orally. Your doctor may adjust your dose based on your response and any side effects that you experience. The maximum recommended daily dose of Adalat XL is 90 mg. However, you should always follow your doctor's instructions and take Adalat XL exactly as prescribed.

Do not stop taking Adalat XL without talking to your doctor as suddenly stopping the medication can cause your blood pressure to rise quickly and may lead to other health problems.
