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 lasts.
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.
Tell your doctor if your condition lasts or gets worse 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 last or get worse, tell your doctor or pharmacist
promptly.
