What It Is and How It Works
Ivermectin lotion is a prescription medication used to treat head lice. The active ingredient, ivermectin, works by binding to the invertebrate nerve and muscle cells of lice, leading to paralysis and death of the parasites. Unlike some other lice treatments, ivermectin lotion affects newly hatched lice as well, eliminating the need for repeated applications and combing for nits.
Indications / Uses
The primary approved use of ivermectin lotion is for the treatment of head lice infestations in children and adults. It is especially beneficial in cases where traditional over-the-counter (OTC) lice treatments have proven ineffective, or when individuals prefer a less labor-intensive treatment option. While it is an effective treatment for lice, ivermectin lotion should only be used for its approved indication and under the guidance of a healthcare professional.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in lotion form, which is applied directly to the scalp and dry hair. It usually comes in single-use tubes containing enough medication for one application. Readers must follow their prescription label and healthcare provider’s instructions. Factors influencing the use include:
- Age: Generally prescribed for individuals older than 6 months.
- Hair length: Dosage may vary based on the length and thickness of hair.
- Skin condition: Sensitive skin may require gentle application and monitoring for irritation.
How to Take It Correctly Step-by-Step
- Ensure hair is completely dry before application.
- Apply the lotion directly to the scalp and hair, ensuring total coverage, especially behind the ears and near the nape of the neck.
- Leave the lotion on for 10 minutes, then rinse with water.
- Wash hands thoroughly after application to remove any traces of lotion.
- Refrain from using other hair products immediately before and after application.
- Store the product at room temperature, away from excessive heat and moisture.
