What It Is and How It Works
Ivermectin lotion is an antiparasitic agent that works by binding to glutamate-gated chloride channels in parasites. This causes an increase in cell permeability, leading to paralysis and death of the lice. Its action is specific to invertebrates, which is why it effectively targets parasites without harming the host.
Indications / Uses
The primary approved use of ivermectin lotion is for the treatment of head lice infestations in patients aged six months and older. It is often prescribed when other lice treatments have failed or when a single-application solution is preferred. While ivermectin has other forms used for different parasitic infections, the lotion is specifically designed for topical application on the scalp.
Dosage Forms and Typical Dosing Considerations
Ivermectin lotion is available as a 0.5% topical solution. The typical treatment involves applying the lotion to dry hair and scalp in sufficient quantity to thoroughly coat the scalp and hair, including areas behind the ears and at the nape of the neck. The lotion should be left on for the recommended duration, usually ten minutes, before rinsing off with water. Always follow the specific instructions provided by your healthcare provider or pharmacist.
How to Take It Correctly Step-by-Step
- Ensure hair and scalp are dry before application.
- Apply enough lotion directly to the scalp and dry hair to cover them completely.
- Pay special attention to the scalp, the area behind the ears, and the nape of the neck.
- Leave the lotion on for ten minutes.
- Rinse thoroughly with water.
- Avoid using other hair products immediately after treatment.
- If you miss a dose, consult your healthcare provider for advice.
