Take ivermectin exactly as prescribed by your healthcare provider, as the dosage may vary based on your condition. For many cases, a single dose is often enough, simplifying the treatment. To ensure the best absorption, it’s recommended to take ivermectin on an empty stomach with a full glass of water, unless your provider advises otherwise. Avoid grapefruit and grapefruit products during treatment, as they can interact with the medication and potentially affect its effectiveness.
