What It Is and How It Works
Ivermectin is an antiparasitic medication widely used to treat infections caused by various parasites, including mites. It works by binding to specific chloride channels unique to the nerve and muscle cells of invertebrates, causing increased permeability to chloride ions. This results in paralysis and death of the parasite. While it effectively targets parasites, ivermectin has a selective mechanism that spares human nerve cells, making it a viable treatment option with a good safety profile.
Indications / Uses
Primarily, ivermectin is used to treat infections by parasitic worms and external parasites such as mites. Its role in treating scabies, a condition caused by mite infestations, is well established. While ivermectin is sometimes used off-label for other mite-related conditions, it should only be used under direct healthcare supervision due to varying evidence. Individuals suffering from scabies or other parasitic mite infections may benefit from ivermectin therapy, but an accurate diagnosis and prescription from a healthcare provider are essential.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in various forms including oral tablets, topical lotions, and injectable forms. The oral form is most common for systemic mite infestations such as scabies. Dosing typically depends on body weight, the severity of the infection, and individual health factors. Special considerations include factors like liver function, kidney function, patient age, and whether the patient is pregnant or breastfeeding. It is critical to follow the dosing instructions provided by a healthcare professional and not to alter dosing without consultation.
How to Take It Correctly Step-by-Step
To take ivermectin correctly, follow these steps:
- Take the oral tablet on an empty stomach, at least one hour before or two hours after a meal.
- Ensure timing aligns with the dosing schedule provided by a healthcare professional.
- If a dose is missed, take it as soon as you remember unless it’s close to the time for your next dose. Do not double up doses.
- Store the medication at room temperature, away from excess heat and moisture, and away from children.
- Avoid alcohol, as it may exacerbate certain side effects such as dizziness.
