Parasite Treatment
Commonly treated with Ivermectin & Mebendazole Combination Capsule
Parasite treatment for adults is usually a short course of oral antiparasitic medication prescribed after provider review, with childrens dosing set case-by-case. A parasitic infection happens when worms like pinworms (threadworms), roundworms, whipworms, or hookworms live in the intestines and feed off the body. Symptoms range from itching and stomach upset to none at all, so infections often go unnoticed. Prescription medication can help get rid of intestinal parasites and clear most infections, though your provider will determine the right option for you.

About Parasite Treatment (Intestinal worms (helminthiasis))
Ivermectin and mebendazole are oral antiparasitic (anthelmintic) medications that target worms and parasites living in the digestive tract. Ivermectin paralyzes many parasites so the body can clear them, while mebendazole starves common intestinal worms by blocking their ability to absorb nutrients. A compounded ivermectin/mebendazole combination pairs both mechanisms in one regimen for broader coverage when a provider determines it is appropriate.

When to see a doctor
Mild to moderate parasite infections are well suited to online treatment — a licensed provider reviews your symptoms and health history and, when appropriate, prescribes an antiparasitic medication without an in-person visit. You should be seen in person if you have a high fever, significant blood in your stool, severe abdominal pain, persistent vomiting, or signs of dehydration, or if symptoms last beyond a couple of weeks or keep returning after treatment. In-person care is also important if you are pregnant or breastfeeding, have a weakened immune system, or are treating a young child, since medication choice and dosing need extra care. Severe pain, high fever, or bloody stools should be evaluated promptly, as they can signal a heavier infection or another condition that needs testing.
