What It Is and How It Works
Ivermectin is an anti-parasitic drug primarily used to treat infections caused by certain types of parasites. It exerts its effects by interfering with specific proteins in parasites, leading to paralysis and death of these organisms. While it is highly effective in the treatment of parasitic infections, it is essential to use it only as intended and prescribed by healthcare professionals.

While there has been interest in off-label uses, such as the potential treatment of COVID-19, reputable health agencies have not approved it for such indications due to insufficient evidence of efficacy and safety.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in tablets for oral use and as a topical cream or lotion for skin applications. The dose and form depend on the condition being treated. Factors influencing dosing include the patient’s age, weight, liver function, and other medications they may be taking. It\’s critical for patients to follow the prescription advice provided by their healthcare professionals, as dosing can vary widely based on the specific condition and patient characteristics.
How to Take It Correctly Step-by-Step

- Store ivermectin at room temperature, away from moisture and heat.
- If you miss a dose, take it as soon as you remember unless it\’s near the time for your next dose. Do not double up on doses.
