Calan SR is a medication that belongs to a class of drugs known as calcium channel blockers. It is commonly prescribed to treat high blood pressure, chest pain (angina), and certain heart rhythm disorders. Calan SR works by relaxing the blood vessels, which allows for easier blood flow and helps to lower blood pressure.

It is important to take Calan SR exactly as prescribed by your healthcare provider. Do not stop taking this medication without consulting your doctor, as suddenly stopping can lead to a rapid increase in blood pressure. It is also important to avoid consuming grapefruit or grapefruit juice while taking Calan SR, as it can interact with the medication and lead to potentially dangerous side effects.

Like all medications, Calan SR may cause side effects in some individuals. Common side effects may include dizziness, headache, constipation, and fatigue. If you experience any severe side effects such as shortness of breath, swelling of the hands or feet, or a rapid or irregular heartbeat, seek medical attention immediately.

Before starting Calan SR, be sure to inform your healthcare provider of any other medications or supplements you are taking, as they may interact with Calan SR. It is also important to disclose any medical conditions you have, especially heart conditions, liver disease, or kidney disease.

Overall, Calan SR can be an effective medication for managing high blood pressure and other heart-related conditions when taken as directed by your healthcare provider. Be sure to follow your doctor’s instructions closely and report any concerning side effects promptly.
