What It Is and How It Works
Ivermectin is an antiparasitic agent that is primarily used to treat infections caused by roundworms, threadworms, and other parasites. It functions by binding to certain chloride channels in the parasite\’s nerve and muscle cells, leading to increased permeability of cell membranes. This results in paralysis and death of the parasite. In human hosts, due to the difference in the host\’s receptor location and affinity, ivermectin has a low potential for toxicity when used correctly.
Indications / Uses
The primary approved use of ivermectin in humans is to treat certain parasitic diseases such as onchocerciasis (river blindness), strongyloidiasis, and intestinal roundworm infections. Veterinary uses include the treatment of heartworm and acariasis in animals. While some studies have explored its potential in treating viral infections, including COVID-19, such uses remain under investigation and are not universally accepted or approved.
Dosage Forms and Typical Dosing Considerations
Ivermectin is commonly available in oral tablet form for humans and as topical formulations for some skin conditions. In veterinary medicine, it is available as injectable, oral, or topical preparations. Dosage depends on the condition being treated, patient weight, and individual response. Dosing can be complicated by factors such as kidney or liver function, particularly in the elderly and those with impaired organ function, where a healthcare provider must tailor the dosing regimen.
How to Take It Correctly Step-by-Step
- For oral tablets, take as directed by your healthcare provider, usually on an empty stomach with water.
- In the case of missed doses, take the missed dose as soon as you remember unless it\’s near the time for the next dose. Do not double up to catch up.
- Store ivermectin in a cool, dry place away from direct sunlight and moisture.
- Adhere strictly to prescribed courses; do not self-medicate without medical advice.
- Avoid mixing with alcohol or other medications unless cleared by a healthcare professional.
Side Effects Common to Serious
Common Side Effects
Common side effects of ivermectin can include mild dizziness, nausea, diarrhea, and dizziness. These symptoms are generally temporary and tend to diminish as your body adjusts to the medication.
Less Common Side Effects
Less frequently, patients may experience headache, joint pain, or temporary worsening of existing conditions caused by the body\’s response to the dying parasites (a phenomenon known as the Mazzotti reaction).
Serious or Rare Side Effects
Serious side effects can include severe skin rash, difficulty breathing, loss of consciousness, and signs of liver damage (such as yellowing of the skin or eyes). Urgent medical attention should be sought if these occur.
Contraindications & Precautions
Ivermectin is contraindicated in individuals with a known hypersensitivity to the drug. Caution is advised in pregnant or breastfeeding women, as well as in people with liver or kidney disease, as ivermectin\’s clearance might be affected. Appropriate dose adjustments or alternative treatments may be necessary in these populations.
Drug, Food, and Supplement Interactions
Ivermectin can interact with other medications, including blood thinners like warfarin and certain anticonvulsants. Alcohol may intensify potential side effects, such as dizziness and sedation. Patients should provide a complete list of medications and supplements used to their healthcare provider.
