What It Is and How It Works
Ivermectin is an antiparasitic medication that targets a broad range of parasites by disrupting their nervous system. It works by binding to certain channels in the parasite\’s cell membranes, leading to paralysis and eventually death of the parasites. This mechanism is effective against parasitic worms like those causing river blindness (onchocerciasis) and lymphatic filariasis.
Indications / Uses
Ivermectin is primarily prescribed for infections caused by various parasites, such as:
- Onchocerciasis (river blindness)
- Lymphatic filariasis
- Strongyloidiasis (threadworm infection)
- Scabies (in certain cases)
Off-label uses should only occur under strict medical supervision, as evidence and guidelines may vary by location.
Dosage Forms and Typical Dosing Considerations
Ivermectin is commonly available in tablet form and is taken orally. The dosing is determined by factors such as the severity of infection, body weight, and medical history. Special populations, such as the elderly or those with liver disease, may require individualized dosing regimens.
It is crucial to follow the prescribing physician\’s instructions and dosage guidelines, as self-prescribing can lead to serious complications.
How to Take It Correctly Step-by-Step
- Take ivermectin on an empty stomach, at least an hour before or two hours after meals, with a glass of water.
- Adhere strictly to the prescribed dosage schedule.
