Do not self-treat without identifying the likely parasite and the type of infection
If you have symptoms, get a stool test and follow the results with a clinician or pharmacist
If you must treat empirically, use an appropriate over-the-counter product matched to suspected parasites (follow the exact label directions)
For pinworms (common in children): treat yourself and all household members as directed on the label; repeat the dose after the label’s recommended interval
For roundworms/hookworms/whipworms: use the label-indicated medication and dosing schedule for the specific target parasite
For tapeworms: use the correct medication for tapeworms as directed; avoid “broad” OTC products unless the label specifically covers tapeworms
Take doses exactly as written; do not exceed the recommended amount
Avoid alcohol if the medication label advises against it
Check for drug interactions and contraindications (pregnancy, breastfeeding, liver disease, age/weight limits, and other medications)
If you are pregnant, breastfeeding, trying to conceive, or treating a child, consult a clinician before taking any deworming medication
Maintain hygiene to prevent reinfection (handwashing, especially before eating and after using the bathroom)
Wash bedding, underwear, and towels used during the prior several days (especially for pinworms) and change daily during treatment
Keep nails short and avoid nail-biting
Clean frequently touched surfaces and shared bathroom items
Cook meat thoroughly and avoid raw/undercooked fish or meat
Drink safe water and avoid swallowing water from potentially contaminated sources
If symptoms persist, worsen, or recur after treatment, seek medical evaluation and repeat testing
Seek urgent care for severe abdominal pain, vomiting, blood in stool, fever, dehydration, jaundice, fainting, or neurological symptoms
If you suspect exposure to specific parasites (travel, contaminated water, certain animals, raw foods), get medical advice for targeted testing and treatment
