Nifedine 20mg Tablet SR is a medicine used for the treatment of hypertension (high blood pressure) and angina (chest pain). It works by relaxing and widening the blood vessels, which improves blood flow and reduces the workload on the heart. It promotes better heart function and overall cardiovascular health. Nifedine 20mg Tablet SR may be prescribed alone or along with other medicines. Your doctor will decide the dose and duration of the treatment. Your doctor may adjust the dose depending on how you respond to this medicine and your blood pressure levels. You can take it at any time of the day, with or without food, but it is best to take it at the same time each day. Keep taking it for as long as advised by your doctor. Even if you feel well, do not stop this medicine on your own because high blood pressure often has no symptoms. If you stop taking it, your condition may get worse. Maintaining an active lifestyle through regular exercise, managing your weight, and consuming a healthy diet will also help regulate your blood pressure.
