Permethrin Cream 5% (Scabies Treatment)
Permethrin Cream 5% is a go‑to, doctor‑recommended treatment for scabies. If you’re dealing with intense nighttime itching, tiny burrows, and a rash that just won’t quit, this is the standard cream many clinicians choose. In plain words: it kills the mites responsible for scabies and helps stop the cycle of itching and spreading. It’s simple to use at home, effective when you use it right, and safe for most people, including kids over 2 months and those who are pregnant or breastfeeding (with usual precautions).
Quick heads‑up: this is general product info. Always follow the exact directions from your prescriber and the leaflet in your pack.
What Permethrin Cream Is Used For
- Scabies (Sarcoptes scabiei) infestations in adults and children 2 months and older
- Crusted (Norwegian) scabies as part of a specialist plan, often with repeat applications and/or oral treatment
- Off‑label, some prescribers may use it for lice on the body or pubic area, but head lice are usually treated with permethrin 1% lotion, not the 5% cream
If the label says 5%, it’s typically for scabies. If you’re treating head lice, check that you have the 1% strength lotion, since the routine is different.
How It Works (short and simple)
Permethrin is a
synthetic version of a natural compound found in chrysanthemums (a pyrethroid). It gets into the mite’s nervous system and basically shuts it down. The mites stop moving, stop feeding, and die. It also affects mite eggs to some extent, but not 100%, which is why a second treatment is often recommended a week later.
Key Benefits
- Kills scabies mites when used as directed
- Helps reduce itching and rash over time
- Easy, single‑night application for most people
- Low absorption through skin, so it’s generally safe and well‑tolerated
- Suitable for the whole household (if advised) to stop reinfestation
Who Can Use It
- Adults and children 2 months of age and older
- Pregnant and breastfeeding individuals (usually considered first‑line; follow your clinician’s advice)
- Older adults
Avoid if you’re allergic to permethrin, other pyrethroids, or any ingredient in the cream. If you’ve had reactions to chrysanthemum/pyrethrin products in the past, talk to your prescriber first.
How To Use Permethrin Cream 5% for Scabies
Follow your prescriber’s instructions this is the usual, step‑by‑step approach many doctors recommend:
1. Prep your skin
- Take a cool, gentle shower or bath first (not hot). Pat dry completely. Skin should be clean, cool, and fully dry before you apply.
- Trim fingernails short so mites and eggs under nails are easier to target.
- Apply a thin, even layer everywhere from the neck down
- Adults and older kids: apply to the entire body from the jawline/neck down, including between fingers and toes, under nails, underarms, bellybutton, buttocks, genital area, and soles of the feet.
- Infants and younger children: as directed by a clinician, apply to the scalp, hairline, temples, and forehead too (avoid eyes and mouth). Don’t forget the back of the ears.
- Use a cotton swab or soft brush to work cream under the fingernails and toenails.
- If someone else is helping you apply, they should wear disposable gloves (nitrile is ideal).
- How much to use
- Most adults need about 30 g (half a standard 60 g tube) per application; larger bodies may need up to a full 60 g tube. Kids need less, based on size.
- Leave it on for 8 to 14 hours
- Overnight is easiest. Don’t take a bath or shower during this time.
- If you wash your hands during the contact time (bathroom breaks, diaper changes, cooking), reapply to your hands and wrists.
- Rinse off
- After 8–14 hours, wash off completely with soap and water. Put on clean clothes.
- Repeat if advised
- Many clinicians advise a second full‑body application in 7 days to catch any newly hatched mites. Follow your label.
- Treat close contacts at the same time
- Anyone living in the same home or with close skin‑to‑skin contact often needs treatment—even if they aren’t itchy yet. That’s how you prevent ping‑pong reinfestation.
Important: For crusted scabies or severe cases, treatment schedules can be different (for example, multiple applications per week plus oral therapy). Follow specialist advice.
What To Expect After Treatment
- Itching can stick around: Post‑scabies itch and rash can last 2–4 weeks even after successful treatment. That doesn’t always mean failure. Your skin is reacting to dead mites/allergens. Hydrating creams, soothing lotions, and your clinician’s recommended anti‑itch plan can help.
- Signs you’re getting better: Fewer new burrows, less intense nighttime itch after the first week or two, and healing of old lesions.
- Signs to call your clinician: New burrows or clear new lesions after a week, severe worsening itch, or symptoms in someone who wasn’t treated in your household.
Cleaning and De‑infestation Tips (so mites don’t bounce back)
Same day as your first treatment, tackle the environment:
-
- Wash recently used clothing, towels, and bedding in hot water and dry on high heat.
- Items that can’t be washed (pillows, plush items, delicate clothing): seal in a bag for at least 72 hours (some go up to 5–7 days). Mites can’t live off the body that long.
- Vacuum mattresses, sofas, carpets, and car seats.
- Don’t share clothes, towels, or bedding until everyone’s cleared.
Side Effects
Most people tolerate permethrin cream well. If side effects happen, they’re usually mild and short‑lived:
- Mild burning, tingling, or stinging after application
- Temporary redness or itching (can overlap with scabies itch)
- Dryness or slight swelling in sensitive areas
Rare but important:
- Allergic reaction (rash, swelling, severe itching beyond the usual, trouble breathing): stop using and seek medical help.
- Eye irritation: rinse eyes with plenty of water if contact occurs.
- If severe skin irritation, open sores, or oozing start, contact your prescriber.
Warnings and Precautions
- External use only. Keep away from eyes, mouth, vagina, and broken skin.
- Don’t apply on freshly shaved or very irritated skin—it may sting more.
- If you’re allergic to permethrin or pyrethroids, don’t use it.
- Babies under 2 months: ask your doctor. Many clinicians use sulfur ointment instead for very young infants.
- Pregnancy and breastfeeding: generally considered safe with minimal absorption. If applying on or near the breasts, apply after feeding and wash the area before the next feed.
- Asthma or very sensitive lungs: though the cream isn’t aerosolized, strong scents or products can irritate some people. Use in a ventilated room and keep it off the face unless directed for infants.
Drug and Product Interactions
Topical permethrin doesn’t have many interaction issues, but keep it simple:
- Don’t layer lots of harsh actives (like strong acids, retinoids, or steroid ointments) under the cream unless your prescriber told you to. It can change absorption or irritate your skin.
- If you’re using topical steroids for itch, most clinicians recommend using them after you’ve washed off permethrin, not at the same time.
- Tell your clinician about all meds and skin products you use, just to be safe.
Storage and Handling
- Store at room temperature, away from direct heat and sunlight.
- Keep the cap tightly closed.
- Keep out of reach of children and pets.
- Do not freeze.
Ingredients (What’s Inside)
- Active: Permethrin 5% w/w
- Inactive (vehicle/base): varies by brand; typically emulsifying waxes, moisturizers, and stabilizers to help the cream spread evenly and stay on the skin.
If you have known sensitivities (fragrances, certain alcohols, lanolin), check the specific brand’s ingredient list.
Why People Choose Permethrin Cream 5%
- First‑line treatment trusted by dermatologists and primary care clinicians
- Strong track record of effectiveness when everyone in the household treats together
- Simple overnight routine—apply once, rinse in the morning
- Safe profile, even for kids and during pregnancy, when used correctly
- Budget‑friendly compared to many alternatives
Extra Tips for Best Results
- Start everyone on the same day if your clinician advised household treatment.
- Wear clean pajamas and use clean bedding after you rinse the cream off.
- Keep fingernails short and clean to reduce skin damage from scratching.
- If your hands are a main problem area, consider cotton gloves at night after applying cream (reapply to hands after any washes).
- Don’t overuse. More cream or longer time on skin won’t make it “extra effective,” it only ups irritation risk. Stick to the plan.
Permethrin Cream vs. Permethrin 1% Lotion
- Permethrin Cream 5%: mainly for scabies. Apply to the whole body (per instructions) and leave on 8–14 hours.
- Permethrin Lotion 1%: for head lice. Applied to scalp and hair for about 10 minutes, then rinsed, with nit combing. Repeat per label (usually 7–10 days later).
Double‑check your product strength so you’re using the right method.

Frequently Asked Questions (FAQ)
Q: What does permethrin cream 5% treat?
A: Mainly scabies. It kills the mites causing the rash and itch. It’s not the standard for head lice that’s usually permethrin 1% lotion.
Q: How long do I leave permethrin cream on?
A: Usually 8–14 hours, then wash off. Overnight works well. If you wash your hands during that time, reapply to hands and wrists.
Q: Do I need a second treatment?
A: Many people do one application and repeat in 7 days to catch any newly hatched mites. Follow your prescriber’s directions.
Q: I’m still itchy after treatment—did it fail?
A: Not necessarily. Post‑scabies itch can last 2–4 weeks while your skin calms down. If you see new burrows or clearly new spots after a week, contact your clinician.
Q: Is permethrin cream safe for kids?
A: Yes, for children 2 months and older, when used as directed. For infants under 2 months, ask your doctor—sulfur ointment is often used instead.
Q: Can I use permethrin while pregnant or breastfeeding?
A: It’s generally considered safe because skin absorption is low. If applying on the chest, do it after a feed and wash off before the next feed. Always confirm with your prescriber.
Q: Do all household members need treatment?
A: Often yes, even if they’re not itchy yet. Scabies spreads through close contact, so treating everyone together helps stop the cycle.
Q: How much cream do I need?
A: Many adults use about 30 g per full‑body application; larger adults may need up to 60 g. Kids need less, based on size.
