-
- nifedipine
-
- DOSAGE FORM
-
- Capsules (10 mg, 20 mg, 30 mg, 60 mg, and 90 mg)

-
- USES
-
- This medication is used to treat various types of angina (chest pain).
- Nifedipine belongs to a group of drugs known as calcium channel blockers. By
- blocking calcium, nifedipine relaxes and prevents spasms of the blood vessels
- of the heart and reduces the oxygen needs of the heart muscle.
-
- TREATMENT
-
- Nifedipine should be taken on an empty stomach with a full glass of water
- one hour before or two hours after a meal (unless your doctor directs you to
- do otherwise). These capsules should be swallowed whole to obtain maximum
- benefit.
- If you miss a dose of this medication, take the missed dose as soon as
- possible, unless it is within two hours of your next scheduled dose. In that
- case, do not take the missed dose at all; just return to your regular dosing
- schedule. Do not double the next dose.
-
- SIDE EFFECTS
-
- Minor.
-
- Bloating, cough, dizziness, flushing, gas, giddiness, headache,
- heartburn, heat sensation, nasal congestion, nausea, nervousness, sleep
- disturbances, sweating, or weakness. These side effects should disappear as
- your body adjusts to the medication.
- If you feel dizzy or light-headed, sit or lie down for a while; get up
- slowly from a sitting or reclining position, and be careful on stairs. To
- avoid dizziness or light-headedness when you stand, contract and relax the
- muscles of your legs for a few moments before rising. Do this by pushing one
- foot against the floor while raising the other foot slightly, alternating feet
- so that you are "pumping" your legs in a pedaling motion.
-
- Major.
-
- Tell your doctor about any side effects that are persistent or
- particularly bothersome. IT IS ESPECIALLY IMPORTANT TO TELL YOUR DOCTOR about
- blurred vision, chills, confusion, difficulty in breathing, fainting, fever,
- fluid retention, impotence, mood changes, muscle cramps, palpitations, rash,
- sore throat, or tremors.
-
- INTERACTIONS
-
- Nifedipine interacts with several other types of medications:
- 1. Nifedipine can increase the active blood levels of digoxin, warfarin,
- phenytoin, and quinine, which can lead to an increase in side effects.
- 2. The combination of nifedipine and beta blockers (acebutolol, atenolol,
- betaxolol, carteolol, esmolol, labetalol, metoprolol, nadolol, penbutolol,
- pindolol, propranolol, or timolol) can lead to a severe drop in blood
- pressure.
- 3. Nifedipine can lower quinidine blood levels, which can decrease its
- effectiveness.
- 4. Cimetidine can decrease the breakdown of nifedipine in the body, which
- can increase the risk of side effects.
- Before starting to take nifedipine, BE SURE TO TELL YOUR DOCTOR about any
- medications you are currently taking, especially any of those listed above.
-
- WARNINGS
-
- * Tell your doctor about unusual or allergic reactions you have had to
- any medications, especially to nifedipine.
- * Tell your doctor if you have ever had heart disease, kidney disease,
- low blood pressure, or liver disease.
- * If this drug makes you dizzy or drowsy, do not take part in any
- activity that requires alertness, such as driving a car or operating
- potentially dangerous machinery.
- * Before having surgery or any other medical or dental treatment, tell
- your doctor or dentist you are taking this drug.
- * Do not stop taking this medication unless you first consult your
- doctor. Stopping this medication abruptly may lead to severe chest pain.
- Your doctor may, therefore, want to decrease your dosage gradually.
- * Be sure to tell your doctor if you are pregnant. Nifedipine has been
- shown to cause birth defects in the offspring of animals that received large
- doses of it during pregnancy. This medication has not been studied in
- pregnant women. Also, tell your doctor if you are breast-feeding an infant.
- It is not known whether nifedipine passes into breast milk.
