What It Is and How It Works
Ivermectin is an antiparasitic medication that belongs to the class of drugs known as avermectins. It is effective against a broad range of parasites, including mites and worms. The drug functions by binding to glutamate-gated chloride channels within the nerve and muscle cells of these parasites, effectively paralyzing and killing them. This process disrupts essential neurotransmission, resulting in the eradication of the parasite from the body.
Indications / Uses
In the United States, ivermectin is approved for the treatment of specific parasitic infections such as onchocerciasis (river blindness), strongyloidiasis (intestinal infection caused by a type of roundworm), and certain types of scabies and lice. There has been significant discussion around its off-label use for other conditions, but such applications should only occur under strict medical supervision due to varying evidence of efficacy and safety.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in multiple formulations, including oral tablets and topical lotions or creams. The oral tablet form is most commonly prescribed for treating parasitic infections. Typical dosing schedules vary based on the type of infection, body weight, and specific patient needs. Factors such as liver or kidney disease, age, pregnancy, and breastfeeding status can significantly impact dosing and should be reviewed by a healthcare provider. Always adhere to the specific dosing instructions provided by your healthcare provider.
How to Take It Correctly Step-by-Step
Follow these general guidelines while taking ivermectin:
- Take it orally with a full glass of water on an empty stomach, at least one hour before or two hours after a meal.
- Do not split, crush, or chew the tablets before swallowing.
- If you miss a dose, take it as soon as you remember unless it\'s almost time for your next dose. Do not double doses.
- Always store ivermectin at room temperature, away from moisture and heat.
- Avoid consuming alcohol close to your dose as it may increase side effects.
