What It Is and How It Works
Ivermectin is a medication used to treat several types of parasitic infestations. It operates by binding to channel proteins within the parasites, causing increased cell membrane permeability. This action leads to paralysis and death of the parasite, helping to clear infections from the host\’s body. For some infections, ivermectin can help reduce the risk of transmission to others.
Indications / Uses
The primary approved uses of ivermectin include treatment for onchocerciasis (river blindness), strongyloidiasis, and other parasitic worm infections. In veterinary medicine, it is also used extensively to prevent and treat heartworms and other parasites in animals. Off-label use in humans has been explored, but it is essential to consult a healthcare provider before considering such use.
Dosage Forms and Typical Dosing Considerations
Ivermectin is commonly available in tablet form for human use, as well as topical formulations for treating lice and other skin conditions. The dosage will vary based on the specific parasitic infection, patient\’s weight, health status, and other factors. It is critical to follow the prescribed dosing by a healthcare provider, considering factors like age and any existing liver or kidney conditions.
How to Take It Correctly Step-by-Step
- Take ivermectin on an empty stomach with a full glass of water unless your provider advises differently.
- If a dose is missed, take it as soon as remembered; skip it if it\’s almost time for the next dose.
- Store at room temperature away from moisture and heat.
- Avoid alcohol to reduce risk of side effects.
- Do not share with others, and refrain from self-prescribing for conditions not approved.
Side Effects Common to Serious
