How to use NIFEDIPINE SUSTAINED-ACTION - ORAL

HOW TO USE: Take this medication by mouth on an empty stomach, usually once daily or as directed by your doctor. Do not crush or chew this medication. Doing so can release all of the drug at once, increasing the risk of side effects. Also, do not split the tablets unless they have a score line and your doctor or pharmacist tells you to do so. Swallow the whole or split tablet without crushing or chewing. 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).

Side Effects

To reduce dizziness and lightheadedness, get up slowly when rising from a sitting or lying position. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.

Many people using this medication do not have serious side effects. Tell your doctor right away if any of these unlikely but serious side effects occur: swelling of the ankles/feet, shortness of breath, unusual weakness/tiredness. Tell your doctor right away if any of these rare but very serious side effects occur: fast/slow/irregular heartbeat, fainting, mental/mood changes, swollen/tender gums, vision changes. Although this medication is effective in preventing chest pain (angina), some people who already have severe heart disease may rarely develop worsening chest pain or a heart attack after starting this medication or increasing the dose. Get medical help right away if you experience: worsening chest pain, symptoms of a heart attack (such as chest/jaw/left arm pain, shortness of breath, unusual sweating). A very serious allergic reaction to this drug is rare. However, seek immediate medical attention if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
