Parasitic infections continue to affect millions of people worldwide, particularly in regions with limited sanitation and access to clean water. Among the most trusted medications for treating certain parasitic worm infections is Praziquantel 600 mg. This prescription antiparasitic drug has been used for decades and is considered highly effective for treating infections caused by flukes and tapeworms in humans.

In this article, we explore what Praziquantel 600 mg is, how it works, the infections it treats, dosage guidelines, benefits, side effects, and important safety considerations.

What Is Praziquantel 600 mg?

Praziquantel is an anthelmintic (anti-worm) medication specifically designed to treat parasitic flatworms. The 600 mg tablet strength is commonly prescribed for adults and is widely used in both individual treatment and mass deworming programs.

It is listed by the World Health Organization (WHO) as an essential medicine due to its effectiveness and safety when used correctly. Praziquantel 600 mg is available only by prescription in many countries and should be taken under medical supervision.

How Does Praziquantel Work?

Praziquantel works by targeting the muscle and outer surface (tegument) of parasitic worms.

Mechanism of Action

• Causes severe muscle contractions in parasites

• Disrupts calcium balance within the worm

• Damages the parasite’s protective outer layer

• Allows the immune system to destroy and eliminate the parasite

Once weakened, the parasites are either expelled from the body or destroyed by the immune response.

Parasitic Infections Treated by Praziquantel 600 mg

Praziquantel is highly effective against several serious parasitic infections in humans, including:

1. Schistosomiasis

A waterborne infection caused by blood flukes (Schistosoma species). Symptoms may include abdominal pain, diarrhea, blood in urine or stool, and long-term organ damage if untreated.

2. Liver Fluke Infections

Including infections caused by Clonorchis sinensis and Opisthorchis species, which can affect the liver and bile ducts.

3. Intestinal Tapeworms

Such as:

• Taenia saginata (beef tapeworm)

• Taenia solium (pork tapeworm)

• Diphyllobothrium latum (fish tapeworm)

4. Other Fluke Infections

Including lung flukes (Paragonimus westermani) and intestinal flukes.

Praziquantel 600 mg is not effective against roundworms or pinworms, which require different medications such as albendazole or mebendazole.

Dosage Guidelines for Praziquantel 600 mg

The dosage of Praziquantel 600 mg depends on the type of infection, body weight, and severity of the condition.
