1. What is Zentel and what is it used for
Zentel contains albendazole, an active substance with antiparasitic action.
Albendazole acts on parasites (worms) and their larvae, preventing them from absorbing sugars (glucose), which causes them to lose energy and die. It also acts on the eggs of parasites.
Zentel is a medicine used to treat diseases caused by parasites (worms), such as:
- infection with human pinworm (enterobiasis);
- infection with hookworm (ancylostomiasis);
- infection with American hookworm (necatoriasis);
- infection with roundworm (strongyloidiasis);
- infection with human roundworm (ascariasis);
- infection with whipworm (trichuriasis);
- infection with tapeworm (taeniasis).
For additional information on parasitic diseases, see section 7 of the leaflet.
2. Important information before using Zentel

Parasitic infections occur when water or food containing parasite eggs or larvae is ingested, which then develop in the intestines. Since the disease may not cause any symptoms at an early stage, the infected person may not be aware of the infection.
Symptoms of the disease depend on the type of worm. Abdominal pain, nausea, diarrhea, anemia, and fatigue may occur. Some parasitic infections can cause symptoms related to other parts of the body, such as the liver, lungs, or brain.
Treatment of intestinal infections is usually easy. Since some worms can migrate to other parts of the body, it is essential to start treatment as soon as possible. This can prevent the development of the disease and permanent damage. Some untreated parasitic infections can be life-threatening.
Prevention of parasitic infections is necessary.
It is crucial to take measures to prevent re-infection, infection of others, and self-reinfection during the use of Zentel.
- Hands should be washed with soap and water after using the toilet, contact with animals, and before each meal.
- It should be ensured that meat intended for consumption has been prepared at a sufficiently high temperature, and fruits and vegetables have been washed in clean water before eating.
