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 taking Zentel
When not to take Zentel
- If the patient has been found to be allergic to albendazole or any of the other ingredients of the medicine (listed in section 6).
- If the patient is pregnant or thinks she may be pregnant (see "Pregnancy and breastfeeding").

If during the use of Zentel at least two of the following symptoms occur:
- headache (which can be severe),
- seizures,
- nausea,
- vomiting,
- vision disturbances,
- the patient should immediately consult a doctor.These symptoms may be caused by the death of parasites in the brain. In some people being treated for parasitic infections, a rare but serious brain infection caused by tapeworms (neurocysticercosis) may occur simultaneously. The patient may not know they have this infection, and taking Zentel may reveal it.

7. Additional information on parasitic diseases
Parasitic infections occur as a result of consuming water or food containing parasite eggs or larvae, 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 affecting other parts of the body, such as the liver, lungs, or brain.
Treating 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.
Protection against worm infections is necessary.
It is crucial to take measures to prevent re-infection, infecting others, and re-infecting oneself during treatment with Zentel.
- Hands should be washed with soap and water after using the toilet, contacting 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.
