Permethrin is a topical medication used to treat scabies, a skin infestation caused by the mite Sarcoptes scabiei. It works by killing the mites and their eggs, disrupting their nerve function and leading to their death. Usually, the cream or lotion is applied evenly over the entire body from the neck down, and sometimes on the head and face in infants or in cases of crusted scabies. The treatment is left on the skin for about 8 to 14 hours before being washed off. In some cases, a second application after a week may be necessary to ensure all mites are eradicated.
Permethrin is generally well tolerated, with the most common side effects being mild skin irritation, redness, or itching at the site of application. Severe allergic reactions are rare. It is important to avoid contact with the eyes, mouth, or broken skin during application. Pregnant women, breastfeeding mothers, and children should use permethrin under medical advice.
Overall, permethrin is an effective and safe first-line treatment for scabies when used according to the instructions provided by a healthcare professional.
You should apply Permethrin Cream to cool, dry skin. Don’t use the treatment on broken skin and avoid using it immediately after having a hot bath or shower. Pay special attention to areas where scabies mites are known to hide. The amount of cream you need will depend on your age and the extent of your infection.
The typical dosage of permethrin for treating scabies is as follows:
- **Adults and children over 2 months old:** Apply a 5% permethrin cream or lotion evenly over the entire body from the neck down. For infants and young children, include the face and scalp if affected (especially in cases of crusted scabies).
- **Application procedure:** Leave the medication on the skin for about 8 to 14 hours, usually overnight, then wash it off thoroughly with soap and water.
- **Repeat treatment:** A second application is often recommended after 7 days to ensure all mites and eggs are eliminated.
Always follow the specific instructions provided by your healthcare provider or the product's leaflet, as dosing may vary based on individual circumstances.
