Scarin Permethrin 5% Cream is a first-line, prescription topical medication primarily used to treat scabies, a highly contagious skin infestation caused by tiny burrowing mites (Sarcoptes scabiei). It works as a neurotoxin that paralyzes and kills both the mites and their eggs.
How to Apply It
For the treatment to succeed, you must follow specific application steps precisely:
-
Preparation: Take a shower or bath, then let your skin cool completely and dry thoroughly before applying.
-
Application: Massage the cream into the skin from the neck down to the soles of the feet. Pay close attention to skin folds, creases, wrists, underarms, between fingers/toes, under fingernails, and the groin.
-
Special Cases: For infants (older than 2 months) and the elderly, the hairline, neck, scalp, and forehead should also be treated.
-
Duration: Leave the medication on the skin for 8 to 14 hours.
-
Reapplication: If you wash your hands or any other treated area during the treatment window, you must reapply the cream to those areas immediately.
-
Removal: Thoroughly wash the cream off by taking a shower or bath after the timeline is complete. Put on completely clean clothes.
-
Repeat Dosing: While one application is often curative, guidelines frequently recommend a second application 7 to 14 days later to eliminate any newly hatched mites.
Critical Eradication Steps
Treating your skin is only half the battle. To prevent reinfection, you must complete environmental decontamination:
-
Household Treatment: All household members and close physical contacts should be treated at the same time, even if they do not show symptoms.
-
Decontaminate Linens: Wash all bedding, towels, and clothing used in the past 3 days in hot water, and dry them on the high-heat cycle.
-
Seal Non-Washables: Items that cannot be washed should be sealed in a plastic bag for at least 72 hours to starve the mites.
Safety & Side Effects
-
The "Scabies Itch": It is normal for skin itching to continue or even worsen for up to 4 weeks after successful treatment. This is an allergic reaction to the dead mites, not a sign that the medication failed.
-
Common Side Effects: Mild skin irritation, burning, stinging, redness, or dryness may occur temporarily.
-
Age Restrictions: Safe for adults and children 2 months of age and older. It is generally avoided in infants under 2 months.
-
Precautions: Do not apply to the face (unless directed), broken skin, eyes, or mucous membranes.
