Nifedipine is used to treat high blood pressure and to control angina (chest pain). Nifedipine is in a class of medications called calcium-channel blockers. It lowers blood pressure by relaxing the blood vessels so the heart does not have to pump as hard. It controls chest pain by increasing the supply of blood and oxygen to the heart.
High blood pressure is a common condition and when not treated, can cause damage to the brain, heart, blood vessels, kidneys and other parts of the body. Damage to these organs may cause heart disease, a heart attack, heart failure, stroke, kidney failure, loss of vision, and other problems. In addition to taking medication, making lifestyle changes will also help to control your blood pressure. These changes include eating a diet that is low in fat and salt, maintaining a healthy weight, exercising at least 30 minutes most days, not smoking, and using alcohol in moderation.
Nifedipine comes as a capsule and an extended-release (long-acting) tablet to take by mouth. The capsule is usually taken three or four times a day. The extended-release tablet should be taken once daily on an empty stomach, either 1 hour before or 2 hours after a meal. To help you remember to take nifedipine, take it at around the same time(s) every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take nifedipine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Swallow the extended-release tablets whole; do not split, chew, or crush them.
Your doctor will probably start you on a low dose of nifedipine and gradually increase your dose, generally once every 7 to 14 days.
If taken regularly, nifedipine controls chest pain, but it does not stop chest pain once it starts. Your doctor may prescribe a different medication to take when you have chest pain.
Nifedipine controls high blood pressure and chest pain (angina) but does not cure them. Continue to take nifedipine even if you feel well. Do not stop taking nifedipine without talking to your doctor. Your doctor will probably decrease your dose gradually.
Before taking nifedipine,
- tell your doctor and pharmacist if you are allergic to nifedipine, any other medications, or any of the ingredients in nifedipine. Ask your pharmacist for a list of the ingredients.
- tell your doctor and pharmacist what other prescription and nonprescription medications, vitamins, nutritional supplements, you are taking or plan to take. Be sure to mention any of the following: acarbose (Precose); anticoagulants ('blood thinners') such as warfarin (Coumadin, Jantoven); antifungals such as fluconazole (Diflucan), itraconazole (Onmel, Sporanox), and ketoconazole (Nizoral); beta blockers such as atenolol (Tenormin), labetalol (Trandate), metoprolol (Lopressor, Toprol XL, in Dutoprol), nadolol (Corgard, in Corzide), propranolol (Inderal, Innopran, in Inderide), and timolol ); carbamazepine (Carbatrol, Epitol, Tegretol); cimetidine (Tagamet); digoxin (Lanoxin); diltiazem (Cardizem); doxazosin (Cardura); erythromycin (E.E.S., E-Mycin, Erythrocin); fentanyl (Actiq, Duragesic, Fentora); flecainide (Tambocor); HIV protease inhibitors including amprenavir (Agenerase), atazanavir (Reyataz), delavirdine (Rescriptor), fosamprenavir (Lexiva), indinavir (Crixivan), nelfinavir (Viracept), and ritonavir (Norvir, in Kaletra); metformin (Glucophage); nefazodone; phenobarbital; phenytoin (Dilantin, Phenytek); quinidine (in Nuedexta); quinupristin and dalfopristin (Synercid); rifampin (Rifadin, in Rifamate, in Rifater, Rimactane); rifapentine (Priftin); tacrolimus (Astagraf SL,Prograf); valproic acid (Depakene); and verapamil (Calan, Covera, Verelan, in Tarka). Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
- tell your doctor what herbal products you are taking, especially St. John's wort.
- tell your doctor if you have or have ever had a narrowing or blockage of your digestive system or any other condition that causes food to move through your digestive system more slowly; or heart, liver, or kidney disease. Also tell your doctor if you have had a myocardial infarction (MI) within the last 2 weeks.
- tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking nifedipine, call your doctor.
- talk to your doctor about the safe use of nifedipine capsules if you are 65 years of age or older. Older adults should not usually take nifedipine capsules because they are not as safe as other medications that can be used to treat the same condition.
- if you are having surgery, including dental surgery, tell your doctor or dentist that you are taking nifedipine.
- ask your doctor about the safe use of alcoholic beverages while you are taking nifedipine. Alcohol can make the side effects from nifedipine worse.
Do not drink grapefruit juice or eat grapefruit 3 days before and while taking nifedipine.
If your doctor prescribes a low-salt or low-sodium diet, follow these directions carefully.
Take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
Nifedipine may cause side effects. Tell your doctor if any of these symptoms are severe or do not go away:
- dizziness or lightheadedness
- fast heartbeat
- muscle cramps
- decreased sexual ability
Some side effects can be serious. If you experience any of the following symptoms, call your doctor immediately or get emergency medical treatment:
- swelling of the face, eyes, lips, tongue, hands, arms, feet, ankles, or lower legs
- difficulty breathing or swallowing
- yellowing of the skin or eyes
- increase in frequency or severity of chest pain (angina)
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature, away from light, and away from excess heat and moisture (not in the bathroom).
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.
In case of overdose, call the poison control helpline at 1-800-222-1222. Information is also available online at https://www.poisonhelp.org/help. If the victim has collapsed, had a seizure, has trouble breathing, or can't be awakened, immediately call emergency services at 911.
Keep all appointments with your doctor and the laboratory. Your blood pressure should be checked regularly to determine your response to nifedipine.
If you are taking certain extended-release tablets (Afeditab CR, Procardia XL), you may notice something that looks like a tablet in your stool. This is just the empty tablet shell, and this does not mean that you did not get your complete dose of medication.
Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
