I have been diagnosed with scabies and have taken the first of two permethrin treatments. The rash is pretty much all over my body, but initially I didn't have it in the pubic
hair and any surrounding hairs on the thighs and around the anus. Avoid getting this medication inside the rectum or vagina and leave the medication for 10 minutes. Then work into a lather using warm water and rinse out thoroughly.
Also wash all clothing, hats, bed clothes, bed linens, and towels in hot water and dry in high heat to prevent reinfection. I hope it helps. Take care and God bless.
