Nifedipine Oral Uses
This medication is used alone or in combination with other drugs to treat high blood pressure (hypertension). Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. Nifedipine belongs to a class of medications known as calcium channel blockers. It works by relaxing blood vessels so blood can flow more easily.
How To Use Nifedipine Oral
Take this medication by mouth on an empty stomach, usually once daily or as directed by your doctor. Swallow this medication whole. Do not crush, chew, or break the tablets. Doing so can destroy the long action of the drug and may increase your risk of side effects.
Your doctor may gradually increase your dose. Follow your doctor's instructions carefully. Dosage is based on your medical condition and response to treatment.
Avoid eating grapefruit or drinking grapefruit juice while being treated with this medication unless your doctor instructs you otherwise. Grapefruit juice can increase the amount of certain medications in your bloodstream. Consult your doctor or pharmacist for more details.
Use this medication regularly in order to get the most benefit from it. Remember to use it at the same time each day. It is important to continue taking this medication even if you feel well. Most people with high blood pressure do not feel sick.
Do not suddenly stop taking this medication without consulting your doctor. Your condition may become worse when the drug is suddenly stopped. Your dose may need to be gradually decreased.
Tell your doctor if your condition worsens (e.g., increase in your routine blood pressure readings).
