🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by binding to the colchicine-sensitive site of tubulin, inhibiting its polymerization into microtubules. This disrupts the parasite's cytoskeleton, leading to impaired glucose uptake, glycogen depletion, and ultimately cell death. The effect is selective for helminths because they rely heavily on microtubules for glucose absorption, whereas human cells are less affected at therapeutic doses.

Dosage Information
| Adult Dosage | For most intestinal worm infections, the usual adult dose is 100 mg twice daily for 3 days, or 500 mg as a single dose, depending on the specific worm. For pinworm, a single 100 mg dose is often used, repeated after 2 weeks. For roundworm, whipworm, and hookworm, 100 mg twice daily for 3 days is common. For tapeworm, 200 mg twice daily for 3 days may be used. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function. |
| Pediatric Dosage | Pediatric dosing is not established from available information. Consult a pediatrician. In general, for children over 2 years, the dose is similar to adults but may be adjusted based on weight. For pinworm, a single 100 mg dose is often used, repeated after 2 weeks. Do not use in children under 2 years without medical advice. |
| Elderly Dosage | No specific dose adjustment is required for elderly patients with normal liver and kidney function. However, because elderly patients may have reduced hepatic or renal function, use with caution and monitor for side effects. |
| Renal Impairment | No dose adjustment is typically needed for mild to moderate renal impairment. In severe renal impairment, caution is advised as the drug is primarily excreted in feces, but the small amount excreted renally may accumulate. Consult your doctor. |
| Hepatic Impairment | In patients with liver impairment, the metabolism of mebendazole may be reduced, leading to increased drug levels. Dose reduction or avoidance may be necessary. Consult your doctor for individualized dosing. |
| Maximum Daily Dose | The maximum recommended daily dose is 500 mg for standard indications. Higher doses may be used in specific cases under medical supervision. |
