Key facts

Mebendazole is an anthelmintic. Per the US prescribing information (VERMOX CHEWABLE), it is used for gastrointestinal roundworm and whipworm infections in patients one year of age and older.

What it is used for

  • Gastrointestinal infections caused by Ascaris lumbricoides (roundworm) and Trichuris trichiura (whipworm) in patients one year of age and older

Dosing

  • One 500 mg chewable tablet as a single dose from one year of age
  • Chew the tablet completely before swallowing; do not swallow it whole
  • For patients who have difficulty chewing: place the tablet on a spoon with about 2 mL to 3 mL of drinking water; within 2 minutes it turns into a soft mass
  • Can be taken without regard to food

Contraindications

  • Known hypersensitivity to mebendazole or its excipients

Important warnings

  • Convulsions reported in infants below the age of 1 year
  • Agranulocytosis and neutropenia at higher doses and longer durations; monitor blood counts in that case
  • Stevens-Johnson syndrome/toxic epidermal necrolysis with concomitant metronidazole; avoid the combination

Side effects

  • In trials: anorexia, abdominal pain, diarrhea, flatulence, nausea, vomiting, rash
  • Postmarketing: agranulocytosis, neutropenia, hypersensitivity including anaphylaxis, convulsions, dizziness, hepatitis, glomerulonephritis, SJS/TEN, angioedema, urticaria, alopecia

Interactions

  • Metronidazole: avoid concomitant use (serious skin reactions)

Pregnancy and breastfeeding

  • Published data have not shown a clear association with major birth defects or miscarriage; untreated helminth infection carries risks
