Mintezol (thiabendazole) is an anthelmintic, or anti-worm, medication used to treat infections caused by worms such as threadworm. Mintezol may also be used to treat pinworm (when it occurs with threadworm), hookworm, whipworm, roundworm, and trichinosis. Common side effects of Mintezol include nausea, vomiting, loss of appetite, upset stomach, diarrhea, dizziness, drowsiness, headache, numbness, unusual urine odor, fever or chills, ringing in the ears, blurred vision or dryness of the eyes, or appearance of live worms in the mouth or nose.
The recommended dosage is one 500 mg tablet, twice daily, after meals, or as directed by your doctor. Mintezol may interact with theophylline (Theo-Dur, Theolair, Theochron, Theo-Bid, and Elixophyllin). Tell your doctor all medications you take. Do not drive, use machinery, or do any activity that requires alertness while taking Mintezol. If you are pregnant, only take Mintezol if the potential benefit outweighs the potential risk to the fetus. It is not known if Mintezol is excreted in breast milk. Consult your doctor before breastfeeding.
