Niclosamide 500mg Tablet (Niclobest)

This medicine contains Niclosamide 500 mg, an anti-worm medicine mainly used to treat tapeworm infections. It is used against beef tapeworm, fish tapeworm, and dwarf tapeworm infections, and it works inside the intestine to help remove the parasite from the body. Current clinical references describe niclosamide as an anthelmintic used for tapeworm infections rather than for roundworms or pinworms.

This medicine is commonly prescribed for:

• Beef tapeworm infection
• Fish tapeworm infection
• Dwarf tapeworm infection
• Other tapeworm infections when advised by a doctor

Authoritative drug references specifically note that niclosamide is used for tapeworm infections and does not work for many other common intestinal worms such as pinworms or roundworms.

This medicine works by damaging the tapeworm on contact inside the intestine. It disrupts the parasite’s energy production and survival, which causes the worm to die and be removed from the body naturally. Current pharmacology references describe niclosamide as a tapeworm treatment that acts locally in the intestine. 

• Take this medicine exactly as prescribed by your doctor.
• It is commonly taken after a light meal or with food, depending on the prescribing advice.
• Some references describe the 500 mg tablet as chewable and recommend chewing thoroughly before swallowing.
• If it is being given to a child, the tablet may be crushed and mixed with a small amount of water if advised by a doctor.
• Follow the exact schedule prescribed for your infection because the course may differ between tapeworm types.

There is some variation among references about whether tablets are swallowed whole or chewed, likely because formulations differ by brand and region. Product-specific directions should follow the prescribed brand label and your doctor’s advice.

Usual Dose:
The dose depends on the type of tapeworm infection and the patient’s age. In older children and adults, a commonly referenced regimen for beef, pork, or fish tapeworm is 2 g as a single dose, while dwarf tapeworm infection may require 2 g on the first day followed by 1 g daily for 6 more days. Current pediatric and drug references describe these infection-specific dosing schedules.

Missed Dose:
If you miss a dose in a multi-day course, take it as soon as you remember. If it is almost time for your next dose, skip the missed dose and continue your normal schedule. Do not take two doses together.

Overdose:
Taking too much may increase the chance of nausea, stomach upset, vomiting, dizziness, or rash. Seek medical attention if overdose is suspected.

• Use this medicine only under medical advice.
• Tell your doctor if you are pregnant or breastfeeding.
• Tell your doctor about any liver problems or other serious health conditions.

Pregnancy guidance is not fully consistent across all sources: some references report no contraindication, while others advise avoiding niclosamide during pregnancy. Because of that inconsistency, the safest guidance is to use it during pregnancy only if specifically recommended by a doctor.
