What It Is and How It Works
Ivermectin is an antiparasitic medication. It works by binding to the chloride ion channels found in the nerve and muscle cells of the parasite. This leads to muscle paralysis and the eventual death of the parasite, helping the body to clear the infection. Ivermectin is effective against a wide range of parasites, including certain types of worms, lice, and mites.
Indications / Uses
Ivermectin is primarily approved for the treatment of onchocerciasis (river blindness), strongyloidiasis (an infection caused by a type of roundworm), and certain other parasitic infections. It is also used off-label for conditions such as scabies and lice infestations. The use of ivermectin for COVID-19 has been a topic of interest, but current evidence does not support widespread use for this purpose outside of clinical trials.
Dosage Forms and Typical Dosing Considerations
Ivermectin is most commonly available in tablet form. Dosing is typically based on the patient\’s weight and specific parasitic infection being treated. Factors that can influence dosing include age, kidney function, liver function, and the presence of other medical conditions or medications. It\’s crucial that patients follow their healthcare provider\’s instructions and the prescription label when taking ivermectin.
How to Take It Correctly Step-by-Step
- Consult your healthcare provider for a specific dosing schedule.
- Take ivermectin tablets with a full glass of water on an empty stomach or as directed by your provider.
- If you miss a dose, consult your healthcare provider. Do not double the next dose without professional guidance.
- Store the medication at room temperature away from moisture and heat.
- Avoid alcohol and consult your doctor before taking other medications or supplements.
Side Effects Common to Serious
Common Side Effects: Dizziness, nausea, diarrhea, fatigue, or rash.
Less Common Side Effects: Headache, muscle pain, or increased heart rate.
Serious Side Effects: Severe allergic reactions (hives, difficulty breathing), neurological effects (confusion, seizures). Seek urgent medical help if you experience these symptoms.
Contraindications & Precautions
Ivermectin may not be suitable for everyone. Those who should use ivermectin with caution include pregnant or breastfeeding women, patients with liver or kidney disease, and individuals with allergies to ivermectin or its ingredients. It is vital to discuss your complete medical history with a healthcare provider before starting treatment.
Drug, Food, and Supplement Interactions
Ivermectin can interact with other medications that are metabolized by the liver, particularly those using the CYP3A4 enzyme pathway. This includes certain antibiotics, antifungals, and some inhibitors of protease and calcium channel blockers. Alcohol can also affect how ivermectin works. Always provide your full medication and supplement list to your healthcare professional to manage potential interactions.
