From the Guidelines
The most effective approach to treating parasitic infections is to use targeted antiparasitic medications, such as albendazole or ivermectin, as prescribed by a healthcare provider after proper diagnosis, taking into consideration the type of parasite, patient's weight, and potential resistance patterns, as recommended by recent guidelines 1. When treating parasitic infections, it's crucial to consider the specific type of parasite and the patient's overall health status. For example, for intestinal parasites like Strongyloides stercoralis, ivermectin is the preferred regimen, with albendazole as a second-line option, for a duration of 2-3 days, as outlined in the 2014 European evidence-based consensus 1. On the other hand, for protozoan parasites like Toxoplasma gondii, sulphadiazine and pyrimethamine are the preferred regimen, with clindamycin plus pyrimethamine as a second-line option, for a duration of 21-28 days 1. Some key considerations when treating parasitic infections include:
- Proper diagnosis to identify the specific type of parasite
- Selection of the most effective antiparasitic medication based on the type of parasite and patient's health status
- Completion of the full course of treatment to prevent reinfection
- Monitoring for potential side effects and adjusting treatment as needed
- Implementation of proper hygiene practices, such as thorough handwashing and drinking clean water, to prevent reinfection. It's also important to note that prevention is key, and measures such as chemoprophylaxis and screening for latent infections, like tuberculosis, should be considered, especially in high-risk populations, as recommended by recent guidelines 1.
From the FDA Drug Label
INDICATIONS AND USAGE STROMECTOL is indicated for the treatment of the following infections: Strongyloidiasis of the intestinal tract. STROMECTOL is indicated for the treatment of intestinal (i.e., nondisseminated) strongyloidiasis due to the nematode parasite Strongyloides stercoralis. Onchocerciasis. STROMECTOL is indicated for the treatment of onchocerciasis due to the nematode parasite Onchocerca volvulus.
The best way to treat parasitic infections is with antiparasitic medications such as:
- Albendazole for certain types of parasitic infections, with careful monitoring for potential side effects like bone marrow suppression and liver damage 2
- Ivermectin for strongyloidiasis and onchocerciasis, as indicated in the drug label 3 It is essential to follow the recommended treatment guidelines and consult a healthcare professional for proper diagnosis and treatment.

Treatment Options for Parasitic Infections
- Antiprotozoan drugs of choice include:
- chloroquine for malaria
- diiodohydroxyquin for asymptomatic intestinal amebiasis
- metronidazole for acute amebic colitis, extraintestinal amebiasis and trichomoniasis
- quinacrine for giardiasis
- quinine-pyrimethamine-sulfadiazine for chloroquine-resistant falciparum malaria
- trimethoprim-sulfamethoxazole for pneumocystis pneumonia 4
- Anthelmintic drugs of choice include:
- mebendazole for roundworm, pinworm, whipworm and hookworm infections
- niclosamide for tapeworm infections
- thiabendazole for trichinosis 4
- Albendazole and mebendazole are broad-spectrum anthelmintics used to treat parasitic infections, including intestinal nematode infections and tissue nematode/cestode infections 5
- Surgical intervention may be important in the diagnosis, treatment, or cure of certain parasitic diseases, including those caused by protozoan and helminthic parasites 6
- Rapid diagnosis of parasitic diseases is crucial, and methods such as microscopy, lateral flow assays, and molecular assays can be used for accurate and rapid diagnosis 7
- Favored chemotherapeutic agents for intestinal parasitic disease include:
- metronidazole and diiodohydroxyquin for amebiasis
- metronidazole for giardiasis
- niclosamide for tapeworm infections
- pyrantel pamoate, piperazine citrate, or pyrvinium pamoate for enterobiasis
- piperazine citrate for ascariasis
- thiabendazole for strongyloidiasis
- mebendazole for trichuriasis
- pyrantel pamoate for hookworm infection
- tartar emetic for schistosomiasis japonica
- niridazole for schistosomiasis mansoni 8
