What It Is and How It Works
Ivermectin is an anti-parasitic medication that functions by binding to parts of the parasite\’s body leading to paralysis and death. For certain parasites, this mechanism of action effectively eradicates the infection in humans.
Technically, ivermectin influences neurotransmission by enhancing inhibitory neural signals, leading to paralysis of the parasites. The result is an inability for the parasites to move or reproduce, ultimately leading to their demise.
Indications / Uses
The primary approved uses of ivermectin in humans include treating onchocerciasis (also known as river blindness) and intestinal strongyloidiasis. It may also be used to manage certain other conditions like scabies or head lice in specific regions. While there have been discussions around using ivermectin for COVID-19, such use is not unanimously backed by clinical evidence or global health organizations, and it is not an approved treatment for COVID-19.
Dosage Forms and Typical Dosing Considerations
Ivermectin is typically available in oral tablet form. When prescribed, the dosing is determined by factors such as the type of parasitic infection, patient weight, and general health. It\’s crucial for the dosage to be strictly adhered to as per the prescribing clinician\’s instructions.
Dosing adjustments may be necessary for patients with liver impairment or other health conditions. Pregnant or breastfeeding women should only use ivermectin if absolutely necessary and prescribed by a healthcare provider.
How to Take It Correctly Step-by-Step
Ivermectin should be taken as prescribed by a healthcare professional. It\’s usually taken on an empty stomach with water. If a dose is missed, take it as soon as remembered unless it\’s close to the time for the next dose—never double up on doses.
Store the medication at room temperature, away from moisture and heat. Avoid alcohol while taking ivermectin as it may increase the risk of side effects.
Common adherence mistakes include discontinuing treatment early or adjusting dosage without consulting a healthcare professional.
Side Effects Common to Serious
Common Side Effects
Include dizziness, nausea, fatigue, and abdominal pain. These typically resolve on their own but should be monitored.
Less Common Side Effects

Serious or Rare Side Effects
Could involve allergic reactions such as hives, difficulty breathing, or swelling of the face, lips, and throat. Seek immediate medical attention if these occur.
Contraindications & Precautions
Ivermectin should be used cautiously in individuals with a history of liver disease, those who are pregnant or breastfeeding, and individuals with compromised immune systems.
People who have had allergic reactions to ivermectin or similar medications should avoid its use.
Drug, Food, and Supplement Interactions
Ivermectin may interact with medications metabolized by the liver, such as anticoagulants. Inform your healthcare provider of all medicines, supplements, or herbal products you are taking.
Avoid alcohol as it could enhance drowsiness and other side effects when taking ivermectin.
