Leave permethrin on the body for 8 to 12 hours To kill the scabies mite, it's important that the permethrin lotion is left on the body for 8 to 12 hours and not washed off. It's best to apply it just before going to bed and leave it on overnight.
After 8-14 hours have passed, wash off the cream by bathing or showering. Your skin may be itchy after treatment with permethrin cream. This does not mean your treatment did not work. If you see live mites 14 days or more after treatment, then you will need to repeat the treatment process.
Two applications of permethrin with a one week interval is more effective than a single dose of ivermectin. Two doses of ivermectin is as effective as a single application of permethrin.
Permethrin is the most effective scabicidal agent in meta-analyses of clinical studies where the treatment success rate of 89%–98% after a single application reaches 98%–100% after repeated application at 1 week intervals.
After 4 weeks, 95% (36/38) of people who received permethrin, 90% (36/40) of people who received 1 dose of ivermectin and 90% (35/39) of people who received 2 doses of ivermectin achieved complete clinical cure. There was no statistically significant difference between these cure rates at 4 weeks.
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.
Abstract. Recently, there have been increased scabies infestations but many patients do not respond to treatment. Clinicians are hesitant to use permethrin despite the fact that treatment failure may be due to noncompliance with the treatment rather than permethrin resistance.
For the first few days to a week, the rash and itch can worsen during treatment. Within four weeks, your skin should heal. If your skin has not healed within 4 weeks, you may still have mites. Some people need to treat two or three times to get rid of the mites.
Medicines work quickly to kill the mites, but the itchy rash may last for several weeks after treatment. Marks on the skin from scabies usually go away in 1 to 2 weeks, but sometimes take a few months to go away.
Permethrin kills the scabies mite and eggs. Permethrin is the drug of choice for the treatment of scabies. Topical permethrin should be administered every 2-3 days for 1-2 weeks to treat crusted scabies.
If itching continues more than 2-4 weeks after initial treatment or if new burrows or rash continue to appear (if initial treatment includes more than one application or dose, then the 2-4 time period begins after the last application or dose), retreatment with scabicide may be necessary; seek the advice of a physician ...
There shouldn't be any new rash after treatment. The itching may last up to 4 weeks. Reason: It's an allergic reaction to the dead scabies.
These symptoms may be a temporary reaction to the remains of the mites. This does not mean this cream did not work or that it needs to be reapplied. If you feel that the itching and rash is intense or if it continues beyond 4 weeks, talk to your doctor or health care professional right away.

It's best to apply it just before going to bed and leave it on overnight.
You or your child can go back to work or school 24 hours after the first treatment. Although the treatment kills the scabies mites quickly, the itching can carry on for a few weeks.
Adding home remedies can help you get rid of scabies faster. At-home treatments, like tea tree oil, oatmeal baths, and over-the-counter (OTC) antihistamines, work alongside prescription treatments to relieve itching and keep the human itch mite from spreading to others.
The activity of this family of mites in the skin creates an allergic reaction that causes the itching. This allergic itching may last for a week or so after treatment, even though the scabies mites are dead. You can get medicine from your family doctor that will help stop the itching.
Notably, scabies can live for 48-72 hours on a mattress. It is also important to note that scabies can still live for up to 72 hours or three days, even without human contact.
However, you do need to wash your bed and pillow sheets in hot water. This should be done the morning after applying the medication at night. You should not shower until you have put the sheets in the wash.
Among 155 patients with scabies treated with permethrin 5% cream, 96 patients were reported as having treatment failures at 1 to 2 weeks follow-up after treatment.
This study showed that 10% sulfur ointment was significantly more effective in treating scabies than 5% permethrin cream (p < 0.001).
However, excessive exposure to the medication can lead to skin irritation, itching, and redness. Additionally, if ingested or inhaled in large amounts, Permethrin can cause more severe symptoms such as headaches, dizziness, and difficulty breathing.
Wear light clothing while permethrin cream is on your skin. Do not let your skin touch anyone else's skin while wearing the cream. After 8 to 14 hours, fully wash cream from skin using warm, soapy water. Wash all bedding, towels, and recently worn clothes in hot water or have them dry cleaned.
Treatment failure, which occurs in about one-third of cases, is considered as a major factor in the increasing incidence of scabies in developed countries.
