Medication Guide

PATIENT INFORMATION Your doctor has prescribed this medicine to treat an infection caused by an intestinal worm. Follow your doctor’s instructions carefully. In addition to your doctor’s treatment, you can help prevent reinfection and infection of other people by understanding a few simple facts about worms. Pinworm Pinworms look like tiny white threads and live in the bowel. Usually at night, they travel to the rectal opening and lay eggs on the outside skin. This sometimes causes itching which may be very annoying. That is why restless sleep is a frequent sign of pinworms, especially in children. Scratching will cause pinworm eggs to stick to the fingers. Reinfection will result if the fingers are placed in the mouth. The eggs, which are too small to see, contaminate whatever they come in contact with: bedclothes, underwear, hands, and food touched by contaminated hands. Even eggs floating in the air can be swallowed and cause infection. Pinworms are highly contagious. Even the cleanest and most careful people can get them. To Help Prevent Reinfection Follow These Rules Wash hands and fingernails with soap often during the day, especially before eating and after using the toilet. Wear tight underpants both day and night. Change them daily. For several days after treatment, clean the bedroom floor by vacuuming or damp mopping. Avoid dry sweeping that may stir up dust. After treatment, wash bed linens and night clothes (don’t shake them). Keep the toilet seats clean. Hookworm, Whipworm and Roundworm These worms also live in the bowel. Eggs from the worms are deposited in the soil if an infected person fails to use a toilet or bathroom. Since the eggs can live only in warm soil, they are found most often where the soil never freezes in winter. People living or traveling in areas with warm winters may have these infections. The eggs in the soil are usually carried to the mouth on food or by contact with dirty hands. In the case of hookworms a pre-adult form of the worm actually penetrates the skin (usually the foot) and burrows its way into the bloodstream. Once inside the body, they grow and breed inside the bowel. New eggs are released in the feces. Therefore, poor sewage disposal or the use of human waste for fertilizer can contaminate the ground with new eggs, which can then reinfect people. The medication used to treat these worms causes them to be expelled from the body. Hookworms and whipworms may be seen and resemble small white threads. Roundworms are much larger and easily seen. To Help Prevent Reinfection Follow These Rules Wash hands and fingernails with soap often during the day, especially before eating and after using the toilet. Wash all fruits and vegetables thoroughly or cook them well. Wear shoes. Use the bathroom. Follow your doctor’s advice, take the medication he gives you and follow the rules mentioned here. If you have other questions about worms, be sure to ask your doctor. WARNING: Do not take this medication if you are pregnant or think you may be pregnant. Consult your physician.

Overdosage & Contraindications

OVERDOSE In the event of accidental overdosage, gastrointestinal complaints lasting up to a few hours may occur. Vomiting and purging should be induced. Activated charcoal may be given. CONTRAINDICATIONS Mebendazole is contraindicated in persons who have shown hypersensitivity to the drug.

Side Effects & Drug Interactions

SIDE EFFECTS Gastrointestinal Transient symptoms of abdominal pain and diarrhea in cases of massive infection and expulsion of worms. Hypersensitivity Rash, urticaria and angioedema have been observed on rare occasions. Central Nervous System Very rare cases of convulsions have been reported. Liver There have been liver function test elevations [AST (SGOT), ALT (SGPT), and GGT] and rare reports of hepatitis when mebendazole was taken for prolonged periods and at dosages substantially above those recommended. Hematologic Neutropenia and agranulocytosis. (See WARNINGS). DRUG INTERACTIONS Preliminary evidence suggests that cimetidine inhibits mebendazole metabolism and may result in an increase in plasma concentrations of mebendazole.

Warnings & Precautions

WARNINGS There is no evidence that mebendazole, even at high doses, is effective for hydatid disease. There have been rare reports of neutropenia and agranulocytosis when mebendazole was taken for prolonged periods and at dosages substantially above those recommended. PRECAUTIONS General Periodic assessment of organ system functions , including hematopoietic and hepatic, is advisable during prolonged therapy. Information For Patient Patients should be informed of the potential risk to the fetus in women taking mebendazole during pregnancy, especially during the first trimester (See Pregnancy). Patients should also be informed that cleanliness is important to prevent reinfection and transmission of the infection. Carcinogenesis, Mutagenesis, Impairment Of Fertility In carcinogenicity tests of mebendazole in mice and rats, no carcinogenic effects were seen at doses as high as 40 mg/kg (one to two times the human dose, based on mg/m2 ) given daily over two years. Dominant lethal mutation tests in mice showed no mutagenicity at single doses as high as 640 mg/kg (18 times the human dose, based on mg/m2 ). Neither the spermatocyte test, the F1 translocation test, nor the Ames test indicated mutagenic properties. Doses up to 40 mg/kg in mice (equal to the human dose, based on mg/m2 ), given to males for 60 days and to females for 14 days prior to gestation, had no effect upon fetuses and offspring, though there was slight maternal toxicity. Pregnancy Teratogenic Effects Pregnancy Category C Mebendazole has shown embryotoxic and teratogenic activity in pregnant rats at single oral doses as low as 10 mg/kg (approximately equal to the human dose, based on mg/m2 ). In view of these findings the use of mebendazole is not recommended in pregnant women. Although there are no adequate and wellcontrolled studies in pregnant women, a post-marketing survey has been done of a limited number of women who inadvertently had consumed mebendazole during the first trimester of pregnancy. The incidence of spontaneous abortion and malformation did not exceed that in the general population. In 170 deliveries on term, no teratogenic risk of mebendazole was identified. Nursing Mothers It is not known whether mebendazole is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when mebendazole is administered to a nursing woman. Pediatric Use The drug has not been extensively studied in children under two years; therefore, in the treatment of children under two years the relative benefit/risk should be considered.
