Microbiology

Definition

Mebendazole is a broad-spectrum anthelmintic drug used to treat parasitic worm infections, particularly those affecting the gastrointestinal tract. It works by inhibiting the synthesis of microtubules, leading to impaired glucose uptake in helminths.

  4. Common side effects include abdominal pain, diarrhea, and headache.
  5. Mebendazole should be avoided during pregnancy due to potential teratogenic effects.
