What It Is and How It Works
Ivermectin is an antiparasitic agent that is effective against a variety of parasitic infections.

This action effectively eliminates the infection from the host\’s body.
Indications / Uses
Approved for the treatment of several parasitic infections including scabies, head lice, and certain worm infestations such as those caused by Strongyloides stercoralis and Onchocerca volvulus. There has been interest in its off-label use for other conditions, but these uses require professional guidance due to varying evidence and possible risks.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several forms, including oral tablets and topical lotions/creams. The appropriate dosing depends on the specific condition being treated, the patient’s age, body weight, liver and kidney function, and potential interactions with other medications. It is essential to follow the prescribing clinician’s instructions.
How to Take It Correctly Step-by-Step
Take ivermectin on an empty stomach, at least one hour before or two hours after a meal. Ensure you follow the prescribed dosing schedule, and do not double-dose if a dose is missed; instead, contact your healthcare provider. Store the medication in a cool, dry place away from light and moisture.
