Permethrin Cream and Lotion: How to Use It Correctly for Scabies

Permethrin 5% is the first-line treatment for scabies, and used correctly it clears the mite in one course. When scabies seems to come back, it is almost always a missed step, not a failed medicine. You apply it from the neck down, leave it on overnight, repeat after a week, and treat everyone at home the same night.

This guide is the complete protocol, including the two steps people skip and the itch that is meant to linger after the mites are gone. One thing to settle first. Permethrin 5% is prescription-strength in the UAE, so use it on a doctor's or pharmacist's advice and follow the instructions on your prescription and the product leaflet. If you are not yet sure your rash is scabies, our guide on how to identify scabies is the place to start.

What is permethrin and how does it treat scabies?

Permethrin is a topical scabicide, the first-line treatment for scabies. Applied to the skin as a 5% cream or lotion, it kills the Sarcoptes scabiei mite and its eggs by disrupting the mite's nervous system. You apply it over the whole body from the neck down, leave it on for 8 to 14 hours, then wash it off, and repeat once after seven days.

Scabies is caused by a tiny mite that burrows into the top layer of skin to live and lay eggs. The intense itch comes from your body reacting to the mite, its eggs, and its waste. Permethrin paralyses and kills the mite by jamming its nerve signals, which is why one correct course is usually enough to end the infestation.

A point the title promises to settle. The 5% strength treats scabies and is prescription-grade. A weaker 1% permethrin is used for head lice. They are not interchangeable, so the scabies treatment is the 5% product, such as Scabi-5, the 5% permethrin lotion MedX stocks. Cream and lotion forms of the 5% strength work the same way. The lotion simply spreads more easily over large areas.

How to apply permethrin for scabies, step by step

Apply permethrin to cool, clean, dry skin over your whole body from the neck down, work it into every crease, leave it on for 8 to 14 hours overnight, then wash it off. Covering the whole body, not just the rash, is the single most missed step, because the mites move beyond the spots you can see.

1. Start with cool, dry skin. Do not apply it straight after a hot bath or shower, as warm skin absorbs more and irritates more. Wait until you have cooled down.
2. Apply a thin layer over the entire body from the neck down. Cover everywhere, including areas with no rash. In adults the face and scalp are usually skipped, but follow your prescriber's advice for the very young or elderly, where the head may need treating too.
3. Work it into the easy-to-miss places. Between fingers and toes, into the webs of the hands and feet, the wrists, elbows, armpits, around the waist, the buttocks, the genitals, and under the fingernails and toenails. Mites love these spots.
4. Reapply to your hands if you wash them within the 8 to 14 hours. Any hand-washing removes the cream from a high-risk area, so put it back on.
5. Leave it on for 8 to 14 hours, usually overnight, then wash it all off. Some leaflets say 8 to 12 hours and others 8 to 14. Follow the time on your product leaflet, and overnight covers it comfortably.

Can you sleep with permethrin on?

Yes, and you should. The standard method is to apply permethrin at night, sleep in it, and wash it off in the morning, which gives the cream the 8 to 14 hours of contact it needs. Wear loose clothing to bed and change your sheets the next day as part of the decontamination steps below.

How many times do you use permethrin? The day-7 repeat

You use permethrin twice, seven days apart. The first application kills the live mites, and the second, applied after seven days, catches any eggs that hatched after the first treatment. Skipping this second dose is one of the two main reasons scabies appears to return.

This is why one application alone often is not enough, even when it seems to be working. Permethrin is strong against adult mites, but eggs already laid can hatch in the days after treatment. The day-7 repeat closes that window. Mark the date when you apply the first dose so the second is not forgotten, because by then the worst of the itch may have eased and it is easy to assume you are done.

Does everyone at home need treatment?

Yes. Everyone in the household and any close physical contacts should be treated on the same night, even if they have no symptoms yet. Scabies spreads through prolonged skin contact, and a newly infected person can be contagious for weeks before they itch. Treating only the person with the rash is the other main reason scabies keeps coming back.

Think of it like the whole house catching the same cold. Treating one person while others quietly carry the mite just hands it back to them a week later. Close contacts means people you share a bed with, family in the same home, and partners, treated together in one coordinated night.

Cleaning your home, bedding and clothes

On the same day you treat your skin, wash all bedding, towels, and clothing used in the last three days at 60°C or hotter, and seal anything you cannot wash in a bag for at least seven days. Mites off the body die within a few days, so this step stops them reinfecting you from fabric.

Run through this checklist on treatment day:

• Hot-wash all bedding, towels, and clothes worn in the last three days at 60°C or above, then dry on high heat.
• Seal items you cannot hot-wash, such as soft toys or delicate fabrics, in a plastic bag for at least seven days. Without a host, the mites die.
• Treat every household member and close contact the same night, as above.
• Vacuum sofas and mattresses if you want extra reassurance, though normal cleaning is enough. There is no need to deep-fumigate the whole home.

Why you still itch after treatment (and how to know it worked)

Itching after permethrin is normal and expected, and it does not mean the treatment failed. The mites are dead. What you are feeling is your skin still reacting to the dead mites, eggs, and waste left in the burrows, and that allergic itch can last two to four weeks as the skin heals and sheds.

This is the fear that sends people back to the tube too soon. The itch persisting is not a sign to keep reapplying permethrin. Overusing it irritates the skin and makes things worse. The sign that it worked is that no new burrows or spots appear after treatment, and the itch gradually fades over the following weeks rather than spreading.

To get through those weeks more comfortably, soothe the skin rather than re-treat it. A soothing relief cream for the lingering itch and a gentle, fragrance-free cleanser while your skin recovers help calm the irritation. For more on barrier repair, our roundup of calming creams for irritated, post-treatment skin covers the options. The rule is simple. If brand-new burrows appear more than four weeks after a full, correct course, see a doctor, because that points to a missed step or a need to re-treat under guidance.

What not to do, and when to see a doctor

Do not use permethrin every day, do not leave it on far longer than directed, and do not keep re-treating because you still itch. One correct course, plus the day-7 repeat, is what clears scabies. Daily or excessive use damages the skin barrier and worsens irritation without killing mites any faster.

See a doctor in any of these situations:

• Scabies has not cleared after a full, correct course with the day-7 repeat.
• The person needing treatment is an infant under two months old.
• You are pregnant or breastfeeding, so your treatment can be confirmed as suitable.
• The skin is crusted, thickened, and scaly. Crusted scabies is a severe form that needs different, specialist treatment.

Mild stinging, redness, or a brief increase in itch right after applying are common and settle quickly. Anything beyond that, or any of the situations above, is a reason to speak to a professional rather than push on alone.

Do you need a prescription for permethrin in the UAE?

Yes. Permethrin 5%, the scabies strength, is a prescription-strength treatment in the UAE. It is not a product to grab over the counter on a hunch, partly because correct diagnosis matters and partly because the dose and repeat schedule need to be right. The 1% lice version is a different, weaker product and is not a scabies treatment.

The straightforward route is to speak to a doctor or a MedX pharmacist about treating scabies correctly and getting the right product. MedX is a licensed UAE pharmacy that dispenses the permethrin lotion available at MedX, so the Scabi-5 page is a sensible reference point for what is stocked and how to start. As a rough guide, a 60ml bottle of Scabi-5 is an affordable single-course treatment, though you should check the current price on MedX since it shifts by pack and promotion.

Frequently asked questions

Do I put permethrin everywhere or just on the rash?

Apply permethrin over your whole body from the neck down, not just on the rash. The mites spread beyond the spots you can see, so treating only the visible rash misses them. Cover every crease, between fingers and toes, and under the nails.

How long do I leave permethrin on?

Leave permethrin on for 8 to 14 hours, usually overnight, then wash it off. Some leaflets state 8 to 12 hours, so follow the time on your specific product. Reapply to your hands if you wash them during that window.

How many days do you use permethrin for scabies?

You use permethrin twice, seven days apart, not daily. The first dose kills live mites and the second catches newly hatched eggs. Using it every day does not work faster and only irritates the skin.

Can I sleep after applying permethrin?

Yes. The standard method is to apply permethrin at night, sleep in it, and wash it off in the morning. Sleeping in it gives the cream the 8 to 14 hours of skin contact it needs to work.

I still itch after treatment, did it not work?

Itching for two to four weeks after permethrin is normal and does not mean it failed. The mites are dead, and your skin is still reacting to what they left behind. As long as no new burrows appear, the itch is part of healing, not a sign to re-treat.

Does everyone at home need to be treated for scabies?

Yes. Everyone in the household and close physical contacts should be treated the same night, even without symptoms, because scabies is contagious before it itches. Treating only the affected person is a common reason it comes back.

Can I use permethrin every day if I'm still itchy?

No. One correct course plus the day-7 repeat is enough, and using permethrin daily damages your skin without clearing scabies faster. If the itch is severe or new spots appear after four weeks, see a doctor instead of reapplying.

Done in full, with the whole household treated together and the day-7 repeat applied, permethrin clears scabies, and the itch that lingers afterwards is your skin healing, not the treatment failing. The mistakes that make it seem to come back are the skipped steps, not the medicine. Since permethrin 5% is prescription-strength, your next step is a quick conversation with a doctor or a MedX pharmacist about getting the right treatment, with the Scabi-5 lotion as your reference for what MedX stocks.
