Bentyl (Dicyclomine Hydrochloride (Dicycloverine))

(dye sye' kloe meen)

Dicyclomine is used to treat the symptoms of irritable bowel syndrome. Dicyclomine is in a class of medications called anticholinergics. It relieves muscle spasms in the gastrointestinal tract by blocking the activity of a certain natural substance in the body.

Dicyclomine comes as a capsule, a tablet, and a syrup to take by mouth. It is usually taken 4 times a day. To help you remember to take dicyclomine, take it around the same times 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 dicyclomine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor. Your doctor will probably start you on a low dose of dicyclomine and gradually increase your dose.

Before taking dicyclomine,
• tell your doctor and pharmacist if you are allergic to dicyclomine or any other medications.
• tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking. Be sure to mention any of the following: amantadine (Symmetrel); antacids; antidepressants such as amitriptyline (Elavil), amoxapine (Asendin), clomipramine (Anafranil), desipramine (Norpramin), doxepin (Adapin, Sinequan), imipramine (Tofranil), nortriptyline (Aventyl, Pamelor), protriptyline (Vivactil), and trimipramine (Surmontil); antihistamines; diet pills; digoxin (Lanoxin); ipratropium (Atrovent); isosorbide (Imdur, Ismo, Isordil, others); medications for anxiety, asthma, glaucoma, irregular heartbeat, mental illness, motion sickness, Parkinson's disease, seizures, ulcers, or urinary problems; metoclopramide (Reglan); monoamine oxidase (MAO) inhibitors, including phenelzine (Nardil) and tranylcypromine (Parnate); narcotic pain relievers such as meperidine (Demerol); nitroglycerin (Nitro-Bid, Nitrostat, others); sedatives; sleeping pills; and tranquilizers. Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
• tell your doctor if you have or have ever had glaucoma; ulcerative colitis (a condition which causes swelling and sores in the lining of the colon [large intestine] and rectum); an enlarged prostate (prostatic hyperplasia); difficulty urinating; esophageal reflux (heartburn); a blockage in the gastrointestinal tract; myasthenia gravis; high blood pressure; an overactive thyroid gland (hyperthyroidism); nerve disease (autonomic neuropathy); heart failure; rapid or pounding heartbeat; hiatal hernia; or liver, kidney, or heart disease.
• tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking dicyclomine, call your doctor. Do not breast-feed while taking this medication.
• talk to your doctor about the risks and benefits of taking dicyclomine if you are 65 years of age or older. Older adults should not usually take dicyclomine because it is not as safe or effective as other medications that can be used to treat the same condition.
• if you are having surgery, including dental surgery, tell the doctor or dentist that you are taking dicyclomine.
• you should know that dicyclomine may make you drowsy or cause blurred vision. Do not drive a car or operate machinery until you know how this medication affects you.
• remember that alcohol can add to the drowsiness caused by this medication.
• you should know that dicyclomine reduces the body's ability to cool off by sweating. In very high temperatures, dicyclomine can cause fever and heat stroke.

Unless your doctor tells you otherwise, continue your normal diet.

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.

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.

Keep all appointments with your doctor. 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.
