Nifedipine is a calcium channel blocker used to treat high blood pressure and angina. It lowers blood pressure by dilating blood vessels, thereby reducing the heart's workload and oxygen demand. Nifedipine may also be used to treat Raynaud's disease and other vasoconstrictive disorders.

When using nifedipine, patients should follow their doctor's recommendations and take the medication on time. Common side effects include headache, dizziness, edema and palpitations. If you experience serious side effects, such as difficulty breathing or chest pain, seek medical attention immediately.

Patients with high blood pressure or heart disease should have their blood pressure and heart function checked regularly to ensure the effectiveness and safety of their medications. While taking nifedipine, avoid drinking alcohol and excessive intake of grapefruit, as they may affect the effectiveness of the drug.

If you have any questions or discomfort, patients should seek help from their doctor immediately.

Dosage

How to use: Nifedipine is a drug that treats high blood pressure and heart disease. It is usually recommended to take it 2 to 3 times daily, with or without food. Avoid taking it with grapefruit juice as it may affect the effectiveness of the medicine. While taking nifedipine, you should avoid excessive or strenuous exercise to avoid affecting heart function.

Dosage Guidelines: The usual starting dose for adults is 5 mg two to three times daily. According to personal circumstances and doctor's advice, the dose may be adjusted to 10 mg each time, and the maximum dose shall not exceed 20 mg each time.
