[Middle English, from Scottish Gaelic clann, family, from Old Irish cland, offspring, from Latin planta, plant, sprout; see plat- in Indo-European roots.]
Word History: The word clan is, from the etymological point of view, the same word as plant. Such a statement may at first appear unlikely to English speakers, since the two words begin with very different consonants. But to the speakers of the Celtic language of Ireland in the 400s, known as Old Irish, c and p sounded quite similar. When St. Patrick converted Ireland to Christianity in the 5th century, the Old Irish language had no consonant p. After their conversion, the Irish began to borrow many words from Latin, and when the speakers of early Old Irish tried to pronounce the sound p in Latin words, the best they could manage was a (kw) or (k) sound, spelled c in Old Irish. For instance, the Latin words purpura, 'purple,' and Pascha, 'Easter,' were borrowed as corcur and Casc. (Later, as their language continued to develop and change, the Irish learned to cope with p, and Modern Irish has many words containing this consonant.) The early Irish also borrowed the Latin word planta meaning 'sprout' or 'sprig,'—also the source of the English word plant—and pronounced it cland. In Old Irish, cland was used to mean not only 'offshoot of a plant' but also 'offspring,' 'family,' and 'clan.' The word cland was carried to the area that is now Scotland when speakers of Old Irish gained power in the region in the late 400s. The form of Old Irish spoken in Scotland eventually developed into the language now known as Scottish Gaelic. In Scottish Gaelic, cland developed the form clann, and it was from Scottish Gaelic that the word clan entered English in the 15th century, at first with reference to the clans of the Scottish Highlands.

Generic Name:verapamil (oral) (ver AP a mil)
Brand Name:Calan, Calan SR, Isoptin SR, Verelan, Verelan PM

What is Calan?


Calan is a calcium channel blocker. It works by relaxing the muscles of your heart and blood vessels.

Calan is used to treat hypertension (high blood pressure), angina (chest pain), and certain heart rhythm disorders.

Calan may also be used for purposes not listed in this medication guide.

Important Information

You should not use Calan if you have a serious heart condition such as 'sick sinus syndrome' or 'AV block' (unless you have a pacemaker), severe heart failure, slow heartbeats that have caused you to faint, or certain heart rhythm disorders of the atrium (the upper chambers of the heart that allow blood to flow into the heart).

Before taking this medicine

You should not use Calan if you are allergic to it, or if you have a serious heart condition such as:

  • 'sick sinus syndrome' or 'AV block' (unless you have a pacemaker);

  • severe heart failure;

  • slow heartbeats that have caused you to faint; or

  • certain heart rhythm disorders of the atrium (the upper chambers of the heart that allow blood to flow into the heart).

To make sure Calan is safe for you, tell your doctor if you have:

  • congestive heart failure;

  • low blood pressure;

  • kidney disease;

  • liver disease; or

  • a nerve-muscle disorder such as myasthenia gravis or muscular dystrophy.

It is not known whether Calan will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant.

Verapamil can pass into breast milk and may cause side effects in the nursing baby. You should not breast-feed while using this medicine.

How should I take Calan?

Follow all directions on your prescription label. Your doctor may occasionally change your dose. Do not use this medicine in larger or smaller amounts or for longer than recommended.

Do not crush, chew, or break an extended-release tablet or capsule. Swallow it whole.

If you have trouble swallowing an extended-release capsule whole, ask your doctor or pharmacist if it is safe for you to open the capsule and sprinkle the medicine into a spoonful of applesauce to make swallowing easier. Swallow this mixture right away without chewing. Do not save the mixture for later use. Discard the empty capsule.

Your blood pressure will need to be checked often. Your kidney or liver function may also need to be checked.

If you need surgery, tell the surgeon ahead of time that you are using Calan.

You should not stop using Calan suddenly. Stopping suddenly may make your condition worse.

If you are being treated for high blood pressure, keep using this medication even if you feel well. High blood pressure often has no symptoms. You may need to use blood pressure medication for the rest of your life.

Calan may be only part of a complete program of treatment that also includes diet, exercise, and other medications. Follow your doctor's instructions very closely.

Store at room temperature away from moisture, heat, and light.

What happens if I miss a dose?

Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. An overdose of Calan can be fatal.

What should I avoid while taking verapamil?

If you also take disopyramide, avoid taking it within 48 hours before or 24 hours after you take Calan.

Calan may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert.

Avoid getting up too fast from a sitting or lying position, or you may feel dizzy. Get up slowly and steady yourself to prevent a fall.

Drinking alcohol can further lower your blood pressure and may increase certain side effects of verapamil.

Grapefruit and grapefruit juice may interact with Calan and lead to potentially dangerous effects. Discuss the use of grapefruit products with your doctor.

Calan side effects

Get emergency medical help if you have signs of an allergic reaction:hives; difficulty breathing; swelling of your face, lips, tongue, or throat.

Call your doctor at once if you have:

  • chest pain, fast or slow heart rate;

  • a light-headed feeling, like you might pass out;

  • shortness of breath (even with mild exertion), swelling, rapid weight gain;

  • lung problems--anxiety, sweating, pale skin, wheezing, gasping for breath, cough with foamy mucus; or

  • liver problems--loss of appetite, upper stomach pain, tiredness, easy bruising or bleeding, dark urine, clay-colored stools, jaundice (yellowing of the skin or eyes).

Common side effects may include:

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
