From the Guidelines
The most effective treatment for pinworms is a single dose of albendazole 400 mg, mebendazole 500 mg, or ivermectin 200 μg/kg, as recommended by the latest guidelines. When considering treatment options for pinworms, it's essential to prioritize medications that have been proven to be effective in eliminating the infection. According to the UK guidelines for the investigation and management of eosinophilia in returning travellers and migrants 1, the recommended treatment for ascariasis, which can be applied to pinworm infections, includes albendazole, mebendazole, or ivermectin. Some key points to consider when treating pinworms include:
- The importance of proper hygiene measures to prevent reinfection, such as frequent handwashing, daily showering, and regular cleaning of toilet seats and bathroom surfaces.
- The need to treat family members or close contacts simultaneously, even if they don't have symptoms, to prevent the spread of infection within households.
- The use of antiparasitic medications, such as albendazole, mebendazole, or ivermectin, which work by paralyzing the worms and eliminating them through bowel movements. It's crucial to note that while the provided study focuses on ascariasis, the treatment recommendations can be applied to pinworm infections, and the latest guidelines support the use of albendazole, mebendazole, or ivermectin as the most effective treatment options 1.
