Question 1

can you use permethrin more than twice?

Accepted Answer

See below: Permethrin can be used more than twice but 2 treatments 1 week apart are almost always curative.  The itching can persist beyond the end of treatment despite cure.  This is treated with calamine lotion or solarcaine for symptomatic relief until it resolves.

Question 2

can use permethrin twice in three days?

Accepted Answer

Yes, but: It may be unnecessary. If using it for scabies, it does usually kill the mites with the first application.However, the itching and irritation are caused by a body response to the debris left in the tunnels created by the mites.This irritation will take weeks to calm down after the mites are dead.

Question 3

what happens if i overdose on permethrin?

Accepted Answer

Tough to overdose: Using Permethrin as directed makes it difficult to overdose with this cream. Using anything indiscriminately is certainly not good practice.

Question 4

what is the typical dosage of permethrin?

Accepted Answer

1 oz: Apply to entire body from neck down and leave on overnight. Repeat  in one week if necessary. Strip sheets and pillow case in morning and wash linens in hot water to kill mites. Also treat everyone else in house even they are symptomatic. Always check if dog or cat is source.

Question 5

how many times can i use permethrin in a week ?

Accepted Answer

Once: It is recommended that you wait 9-10 days before repeating it.  There is resistance to the medication now and therefore it may not be effective. Also itching may continue if you have scabies infection even though the mite has been killed.  You should see your doctor to see if another medicine needs to be prescribed.

Question 6

how long does permethrin stay active in your system?

Accepted Answer

Difficult question: Permethrin is only minimally absorbed into the bloodstream (less than 2%) after topical application, but it is a VERY stable compound with a long half life.  The amount absorbed is considered below the toxic level, but it will remain for quite some time (this is based on a study on rats, I could not find human studies).  Hope this helps.

Question 7

can you develop new bites after using elimite (permethrin)?

Accepted Answer

Scabies killed: Scabies treatments often contain a high percentage of alcohol which can be very drying to the skin.  Rash and itching can persist for two weeks, but all mites should be dead  (new bumps shouldn't develop unless reinfected or treatment not completed).  Evaluation with a skin scraping can determine treatment success

Question 8

how long does it take for permethrin take to start working?

Accepted Answer

One application: It used overnight and works within 8 hours. Itching can persist for days as the mites die off and may need to be treated with a prescription steroid cream.

Question 9

because i need to know if taking permethrin 2 days in a row is safe?

Accepted Answer

That isn't the: normal dosing, but what are you taking it for, and did you just take an extra dose?

Question 10

how effective is nix (permethrin)?

Accepted Answer

Not always: Some sarcoptes scabiei (mite causing scabies) became resistant to nix (permethrin) and requires lindane treatment.
