From the FDA Drug Label
Mebendazole tablets are indicated for the treatment of Enterobius vermicularis (pinworm), Trichuris trichiura (whipworm), Ascaris lumbricoides (common roundworm), Ancylostoma duodenale (common hookworm), Necator americanus (American hookworm) in single or mixed infections. Efficacy rates derived from various studies are shown in the table below: Pinworm (enterobiasis) Cure rates mean 95%
The most effective treatment for Enterobius vermicularis (pinworms) is mebendazole (PO) with a cure rate of 95% 1.
- Key points:
- Mebendazole is effective against pinworms
- Cure rate is 95%
- Efficacy may vary depending on several factors, such as preexisting diarrhea and gastrointestinal transit time, degree of infection, and helminth strains.
From the Research
The most effective treatment for Enterobius vermicularis (pinworms) is a single dose of an anthelmintic medication such as albendazole (400 mg) or mebendazole (100 mg), given their safety and effectiveness as stated in the most recent study 2.
Treatment Options
- Albendazole (400 mg) is a highly effective option, as it is both adulticidal and ovicidal, meaning it can kill both the adult worms and their eggs.
- Mebendazole (100 mg) is also a viable option, with similar properties to albendazole.
- Pyrantel pamoate (11 mg/kg, maximum 1 gram) is another alternative, although it is only adulticidal, requiring a second dose to ensure all worms are eliminated.
Treatment Approach
- A single dose of the chosen medication is typically recommended, followed by a second dose 2 weeks later to kill any newly hatched pinworms.
- It is essential to treat all household members simultaneously, even if they do not exhibit symptoms, due to the highly contagious nature of the infection.
- Thorough hygiene measures are crucial to prevent reinfection, including:
- Washing bedding, underwear, and pajamas in hot water
- Vacuuming living areas
- Cleaning bathroom surfaces
- Encouraging regular handwashing, especially after using the toilet and before eating
- Keeping fingernails short and avoiding scratching the anal area to prevent the spread of eggs.
Considerations
- The chosen medication should be well-tolerated with minimal side effects, making them safe and effective options for treating this common parasitic infection.
- For pregnant women, pyrantel is preferred over mebendazole and albendazole, as stated in the study 2.
- Recurrences are common due to repeated cycles of reinfection, emphasizing the importance of good personal hygiene and simultaneous treatment of all household members.
