Verapamil is used to treat high blood pressure and to control angina (chest pain). The immediate-release tablets are also used alone or with other medications to prevent and treat irregular heartbeats. Verapamil is in a class of medications called calcium-channel blockers. It works by relaxing the blood vessels so the heart does not have to pump as hard. It also increases the supply of blood and oxygen to the heart and slows electrical activity in the heart to control the heart rate.

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.

Verapamil comes as a tablet, an extended-release (long-acting) tablet, and an extended-release (long-acting) capsule to take by mouth. The regular tablet is usually taken three to four times a day. The extended-release tablets and capsules are usually taken once or twice a day. Take verapamil at around the same time(s) every day. Certain verapamil products should be taken in the morning and others at bedtime. Ask your doctor what the best time is for you to take your medication. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take verapamil 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 and capsules whole. Do not chew or crush them. Ask your pharmacist if the tablets may be split in half, as the instructions vary by product.

If you can not swallow the extended-release capsules you may carefully open the capsule and sprinkle the entire contents onto a spoonful of applesauce. The applesauce should not be hot, and it should be soft enough to be swallowed without chewing. Swallow the applesauce immediately without chewing, and then drink a glass of cool water to make sure that you have swallowed all of the medicine. Do not store the mixture for future use.

Your doctor will probably start you on a low dose of verapamil and gradually increase your dose.

Verapamil controls arrhythmias, high blood pressure, and angina but does not cure these conditions. Continue to take verapamil even if you feel well. Do not stop taking verapamil without talking to your doctor.

Verapamil is also sometimes used to treat certain other heart problems. Talk to your doctor about the risks of using this medication for your condition.

This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

Before taking verapamil,

  • tell your doctor and pharmacist if you are allergic to verapamil, any other medications, or any ingredients in verapamil. Ask your pharmacist for a list of the ingredients.

  • tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, and nutritional supplements you are taking or plan to take. Be sure to mention any of the following: alpha blockers such as prazosin (Minipress); antifungals such as itraconazole (Onmel, Sporanox) and ketoconazole (Nizoral); aspirin; beta blockers such as atenolol (Tenormin, in Tenoretic), metoprolol (Lopressor, Toprol XL, in Dutoprol), nadolol (Corgard, in Corzide), propranolol (Inderal, Innopran, in Inderide), and timolol (Blocadren, in Timolide); carbamazepine (Carbatrol, Epitol, Equetro, Tegretol); cimetidine (Tagamet); clarithromycin (Biaxin, in Prevpac); cyclosporine (Neoral, Sandimmune); digoxin (Lanoxin); disopyramide (Norpace); diuretics (''water pills''); erythromycin (E.E.S., Eryc, Erythrocin); flecainide; certain HIV protease inhibitors such as indinavir (Crixivan), nelfinavir (Viracept), and ritonavir (Norvir, in Kaletra); quinidine (in Nuedexta); lithium (Lithobid); medications to treat high blood pressure; nefazodone; phenobarbital; pioglitazone (Actos, in Duetact, in Oseni); rifampin (Rifadin, Rimactane); telithromycin (Ketek); and theophylline (Theochron, Theolair, Uniphyl). Your doctor may need to change the doses of your medications or monitor you carefully for side effects. Many other medications may also interact with verapamil, so be sure to tell your doctor about all the medications you are taking, even those that do not appear on this list.

  • tell your doctor what herbal products you are taking, especially St. John's wort.

  • tell your doctor if you have or have ever had narrowing or blockage of your digestive system or any other condition that causes food to move through your digestive system more slowly; heart failure; heart, liver, or kidney disease; muscular dystrophy (inherited disease that causes gradual weakening of muscles); or myasthenia gravis (condition that causes certain muscles to weaken).

  • tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking verapamil, call your doctor.

  • if you are having surgery, including dental surgery, tell your doctor or dentist that you are taking verapamil.

  • talk to your doctor about the safe use of alcoholic beverages during your treatment with verapamil. Verapamil may cause the effects of alcohol to be more severe and longer-lasting.

Talk to your doctor about eating grapefruit or drinking grapefruit juice while taking this medicine.

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.

  • Verapamil may cause side effects. Tell your doctor if any of these symptoms are severe or do not go away:

    • constipation

    • heartburn

    • dizziness or lightheadedness

    • headache

  • 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 hands, feet, ankles, or lower legs

    • difficulty breathing or swallowing

    • slow heartbeat

    • fainting

    • blurred vision

    • rash

  • If you experience a serious side effect, you or your doctor may send a report to the Food and Drug Administration's (FDA) MedWatch Adverse Event Reporting program online (http://www.fda.gov/Safety/MedWatch) or by phone (1-800-332-1088).

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature 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.

Symptoms of overdose may include:

  • dizziness

  • blurred vision

  • slow, fast, or irregular heartbeat

  • seizures

  • confusion

  • difficulty breathing or swallowing

Keep all appointments with your doctor and the laboratory. Your blood pressure should be checked regularly to determine your response to verapamil. Your doctor may also order certain lab tests to check your body's response to verapamil.

If you are taking certain extended-release tablets (Covera HS), 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.
