Ivermectin is commonly available in tablet form for oral administration and as topical formulations for external use. Dosing is typically determined based on factors like the patient’s weight, the specific type of infection being treated, and individual health conditions. Importantly, patients must follow their healthcare provider\’s dosing instructions and consult them for any specific concerns.
How to Take It Correctly Step-by-Step
Ivermectin should generally be taken as prescribed by a healthcare provider, often on an empty stomach with water to maximize absorption. If a dose is missed, patients should take it as soon as they remember unless it is nearly time for the next dose. It\’s important not to double doses as a catch-up measure.
