Nifedipine belongs to the class of medications called calcium channel blockers. It is used to treat high blood pressure and Angina (chest pain brought on by exercise or stress). It works to control blood pressure and reduce the number of angina attacks by relaxing blood vessels. The immediate-acting form of nifedipine is also used to treat coronary spasm, the sudden constriction of the coronary artery in the heart.

Nifedipine may be taken with or without food. The long-acting forms of the medication should be swallowed whole and should not be bitten, crushed, chewed or divided. Dosage is based on individual tolerance and response, and should be started at a low dose. Higher doses (e.g., 60 mg or 90 mg) are not recommended for initial treatment. Higher doses should be used for treatment once the dose has been stabilized.

An interaction between two medications does not always mean that you must stop taking one of them. Speak to your doctor about how any drug interactions are being managed or should be managed.
Medications other than those listed above may interact with Nifedipine Er. Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications you are taking. Also tell them about any supplements you take. Since caffeine, alcohol, the Nicotine from cigarettes, or street drugs can affect the action of many medications, you should let your prescriber know if you use them.
Before you begin using a medication, be sure to inform your doctor of any medical conditions or Allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use Nifedipine Er.
Diabetes: For people with diabetes, nifedipine may affect their control of blood sugar levels. If you have diabetes, discuss with your doctor how Nifedipine Er may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Nifedipine Er, and whether any special monitoring is needed. It may be necessary to check your blood sugar regularly until you know how Nifedipine Er affects your blood sugar control.
Fertility: Nifedipine Er may affect male fertility. Talk to your doctor if this is important to you.
Grapefruit juice: Grapefruit juice can increase blood levels of nifedipine. Avoid drinking grapefruit juice or eating grapefruit before or while you are taking nifedipine.
Heart attack: Immediate-release nifedipine should not be used within one week after a heart attack.
Heart failure: Rarely, nifedipine causes severely decreased blood pressure, making symptoms of heart failure worse for people with severe heart failure. If you have heart failure, discuss with your doctor how Nifedipine Er may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Nifedipine Er, and whether any special monitoring is needed.
Liver function: Liver disease or reduced liver function may cause Nifedipine Er to build up in the body, causing side effects. If you have liver problems, discuss with your doctor how Nifedipine Er may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Nifedipine Er, and whether any special monitoring is needed. Your doctor may want to test your liver function regularly with blood tests while you are taking Nifedipine Er.
If you experience symptoms of liver problems such as fatigue, feeling unwell, loss of appetite, nausea, yellowing of the skin or whites of the eyes, dark urine, pale stools, abdominal pain or swelling, and itchy skin, contact your doctor immediately.
Low blood pressure: People prone to low blood pressure should monitor their blood pressure frequently while they are taking nifedipine. Blood pressure may occasionally drop more than expected when starting nifedipine. Be alert for any lightheadedness, dizziness, or a faster than normal heart rate. Move slowly when changing from a lying down to an upright position. If your blood pressure drops too low, your doctor will adjust your dose or try another medication.
Stomach disorders: People with certain stomach disorders (e.g., narrowing of the gastrointestinal tract) should talk with their doctor about the risks and benefits of taking Nifedipine Er. If you have any stomach disorders, such as a narrowing of the gastrointestinal tract, discuss with your doctor how Nifedipine Er may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Nifedipine Er, and whether any special monitoring is needed.
Surgery: If you are scheduled for surgery, inform your doctor that you are taking Nifedipine Er.
