What STROMECTOL Is Used For

STROMECTOL is an antiparasitic medicine used to treat the following infection:

  • Treatment of intestinal strongyloidiasis.
  • Treatment of parasites in the blood or tissue caused by Wuchereria bancrofti.
  • Treatment of human scabies after prior treatment has failed.

Intestinal Strongyloidiasis

Strongyloidiasis is an infection caused by the roundworm Strongyloides stercoralis. This tiny worm is barely visible to the naked eye. Exposure occurs when skin has direct contact with contaminated soil. Young roundworms penetrate the skin. They migrate through the bloodstream to the lungs and up the large airways. The worms are then swallowed, and the young worms mature and bury themselves into the intestinal wall. Adult roundworms begin producing eggs in the intestines.

Wuchereria Bancrofti

This is a parasite that is carried and transmitted by the mosquito. It travels through the bloodstream and settles in the lymph and tissue of the patient, this can lead to fever and severe inflammation around the area the parasite has migrated to.

Human Scabies

Scabies is an infectious disease of the skin caused by a mite barely visible to the human eye called Sarcoptes scabiei var hominis. The mite burrows into the skin and causes a rash like reaction which can be very itchy and uncomfortable for the patient. Human scabies is almost always caught from another person by close contact.

How STROMECTOL Works

STROMECTOL belongs to a group of medicines called an anthelmintic, these are medicines which bind to the nerve and muscle cells of parasites, resulting in their death.

Your doctor may have prescribed STROMECTOL for another reason. Ask your doctor if you have any questions about why STROMECTOL has been prescribed for you.

STROMECTOL is not addictive.
