              HYOSCYAMINE - ORAL

              (hi-oh-SYE-uh-meen)

              COMMON BRAND NAME(S): Anaspaz, Cystospaz, Donnamar, Levsin

              USES: Hyoscyamine is used to treat a variety of stomach/intestinal problems such as cramps and irritable bowel syndrome. It is also used to treat other conditions such as bladder and bowel control problems, cramping pain caused by kidney stones and gallstones, and Parkinson's disease. In addition, it is used to decrease side effects of certain medications (drugs used to treat myasthenia gravis) and insecticides.This medication works by decreasing acid production in the stomach, slowing down the natural movements of the gut, and relaxing muscles in many organs (such as the stomach, intestines, bladder, kidney, gallbladder). Hyoscyamine also lessens the amount of certain body fluids (such as saliva, sweat). This medication belongs to a class of drugs known as anticholinergics/antispasmodics.

              HOW TO USE: Take this medication by mouth as prescribed, usually 30-60 minutes before meals, or as directed by your doctor.Dosage is based on your medical condition and response to therapy. Do not increase your dose or take it more often than prescribed without consulting your doctor. Adults and children 12 years and older should not take more than 1.5 milligrams in 24 hours. Children aged 2 to 12 years should not take more than 0.75 milligrams in 24 hours. Ask your doctor or pharmacist for more information.Antacids lower the absorption of hyoscyamine. If you use antacids, take them after meals and take hyoscyamine before meals; or take antacids at least 1 hour after taking hyoscyamine.Drink plenty of fluids while taking this medication unless your doctor directs you otherwise.Tell your doctor if your condition lasts or gets worse.

              SIDE EFFECTS: Dizziness, drowsiness, blurred vision, dry mouth, vision problems, headache, trouble sleeping, constipation, flushing, dry skin, and decreased sweating may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.To relieve dry mouth, suck on (sugarless) hard candy or ice chips, chew (sugarless) gum, drink water or use a saliva substitute.Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.Tell your doctor right away if you have any serious side effects, including: mental/mood changes (such as confusion, unusual excitement), fast/irregular heartbeat, difficulty urinating, decreased sexual ability, loss of coordination, trouble speaking, vomiting.Get medical help right away if you have any very serious side effects, including: eye pain/swelling/redness, vision changes (such as seeing rainbows around lights at night).A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.In the US -Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088 or at www.fda.gov/medwatch.In Canada - Call your doctor for medical advice about side effects. You may report side effects to Health Canada at 1-866-234-2345.

              PRECAUTIONS: Before taking hyoscyamine, tell your doctor or pharmacist if you are allergic to it; or to atropine; or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.Before using this medication, tell your doctor or pharmacist your medical history, especially of: enlarged prostate, urinary blockage problems, certain stomach/intestinal problems (such as slow gut, blockage, severe ulcerative colitis, infection), personal or family history of glaucoma (angle-closure type), overactive thyroid, heart problems (such as coronary heart disease, heart failure, fast heartbeat, arrhythmias), high blood pressure, kidney disease, heartburn problems (acid reflux, hiatal hernia), certain nervous system problem (autonomic neuropathy), myasthenia gravis.Contact lens wearers may need to use wetting eye drops since this medication can cause dry eyes.This drug may make you dizzy or drowsy or blur your vision. Alcohol or marijuana (cannabis) can make you more dizzy or drowsy. Do not drive, use machinery, or do anything that needs alertness or clear vision until you can do it safely. Limit alcoholic beverages. Talk to your doctor if you are using marijuana (cannabis).This drug may increase the risk for heatstroke because it decreases sweating. Avoid becoming overheated in hot weather, saunas, and during exercise or other strenuous activity.Older adults may be more sensitive to the side effects of this drug, especially confusion, drowsiness, unusual excitement, constipation, and difficulty urinating. Confusion and drowsiness can increase the risk of falling.Children may be more sensitive to the effects of this drug.During pregnancy, hyoscyamine should be used only when clearly needed. Discuss the risks and benefits with your doctor.This drug passes into breast milk. Consult your doctor before breast-feeding.
