What is Permethrin for?

Permethrin is a medicine with a function to treat scabies, a disease caused by small insects called mites that stick to your skin and cause irritation. Permethrin belongs to a class of drugs called pyrethrins. Permethrin works by paralyzing and killing their mites and eggs.

The permethrin dose and permethrin side effects will be explained further below.

How to use Permethrin?

This medicine is an external medicine, only used on the skin. Use this medicine as soon as possible after it is recommended. Apply the medicine from the head to the sole of the foot, including under the nails and skin folds as between the toes as suggested. Massage the cream into the skin. Do not use more drugs than prescribed. Wash the cream after 8-14 hours while bathing.

Avoid creams entering the eyes, nose, mouth, or vagina. If medication hits your eyes, flush eyes with plenty of water. Consult your doctor if irritation occurs.

Symptoms of scabies include itching which is usually worse while sleeping. You can also see thin, wavy fine lines on the skin with small insects at the ends (burrows). Burrows are usually found in the webs of fingers, toes, wrists, elbows, armpits, belt lines, the bottom of the buttocks, women’s nipples, or men’s genitals. Even if permethrin kills all these insects, dead mites can still make you itch for up to 4 weeks after treatment. Ask your doctor about other medicines that can be used to relieve itching. Tell your doctor if your condition remains the same or even worsens within 2 weeks after treatment. Chances are your doctor needs to look for surviving mites and recommend more intensive treatments.
