This medication is used to treat scabies, a condition caused by tiny insects called mites that infest and irritate your skin. Permethrin belongs to a class of drugs known as pyrethrins. Permethrin works by paralyzing and killing the mites and their eggs.
This medication is for use on the skin only. Apply this medication as soon as possible after it is prescribed. Apply the medicine from your head to the soles of your feet, including under your nails and in skin folds such as between the toes, as directed. Massage the cream into the skin. Do not use more medication than prescribed. Wash off the cream after 8-14 hours by showering or taking a bath.
Avoid getting the cream into your eyes, nose, mouth, or vagina. If the medication gets in your eyes, flush the eyes with plenty of water. Consult your doctor if irritation persists.
Symptoms of scabies include an intense itching that is usually worse at bedtime. You may also see small, fine, wavy lines on the skin with a tiny insect at the end (a burrow). Burrows are usually found on finger/toe webs, wrists, elbows, armpits, belt line, lower buttocks, female nipples, or male genitals. Even if permethrin kills all the scabies, the dead mites can still make you itch for up to 4 weeks after treatment. Ask your doctor about other medications that may be used to soothe the itching. Inform your doctor if your condition persists or worsens 2 weeks after treatment. Your doctor may need to look for living mites and recommend more treatment.
Skin irritation, including itching, swelling, and redness, may occur with scabies and temporarily worsen after treatment with permethrin. Mild burning or stinging may also occur. If any of these effects persist or worsen, notify your doctor or pharmacist promptly.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
A very serious allergic reaction to this drug is rare. However, seek immediate medical attention if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
