What It Is and How It Works
Ivermectin is an antiparasitic medication that combats infections caused by certain parasites. It acts by binding to invertebrate muscle and nerve cells, increasing the permeability of cell membranes to chloride ions, which leads to paralysis and death of the parasites.
Indications / Uses
The primary uses of ivermectin include the treatment of infections caused by parasites such as roundworms, threadworms, and other similar worms. While some discussions have occurred regarding its use in treating viral infections, such as COVID-19, these applications are not approved and should only be considered under clinical supervision.
Dosage Forms and Typical Dosing Considerations
Ivermectin typically comes in oral tablet form, but topical formulations exist for certain conditions like head lice and rosacea. The dosing is highly dependent on the condition being treated, the patient\’s weight, and other factors like renal or liver function. Always adhere to the prescribed dosing instructions provided by your healthcare provider.
How to Take It Correctly Step-by-Step
Take ivermectin as prescribed by your healthcare provider. Generally, it is taken on an empty stomach with a full glass of water. If you miss a dose, take it as soon as you remember unless it is close to the time of your next scheduled dose. Do not double the doses to catch up. Store at room temperature, away from moisture and heat.

Minor side effects include nausea, dizziness, and lightheadedness. Typically, these are not severe and subside as your body adjusts to the medication.
