MedDataToolFelodipine is a medication used to treat high blood pressure, helping to lower the risk of serious heart problems like strokes and heart attacks. It works by relaxing the blood vessels, making it easier for blood to flow. You typically take it as an extended-release tablet once a day, starting with a dose of 5 mg, which can be adjusted between 2.5 mg and 10 mg based on your response, but should not exceed 10 mg daily. It's important to know that if you're allergic to felodipine, you should not take it. Additionally, if you are taking grapefruit juice, be cautious, as it can increase the levels of felodipine in your body.
