I am assuming: You have treated your bedding and clothing!!
Scabies (if that's your problem) is a frustrating infestation and may require more than one treatment to eliminate!

Hope this helps! Good luck! ]]

Is it possible for more bumps to appear 2 days after permethrin treatment? I read that it's suppose to kill all the scabies mites but I have new bumps

Is it possible for more bumps to appear 2 days after permethrin treatment? I read that it's suppose to kill all the scabies mites but I have new bumps

Scabies symptoms: The symptoms of scabies -- itchy red bumps -- are not due to live mites, but the body's allergic reaction to the mites, their egg, etc. It takes a while for these to be absorbed and the immune reaction to stop. Therefore, itching and new bumps commmonly continue for several days after treatment. Hang in there; it will clear up! If it takes more than 10 days or so, contact your doctor. ...Read more

I used Permethrin 5% 10 days ago and 3 days ago. I got new itchy bumps after 2d application. I wash diligently. When should I try a third application?

No.: You may be having a reaction to the medicine. See your doc and see if you still need treatment, or if so, if another medicine would be better. In the meantime, avoid fragrances in soaps, detergents and fabric softeners. Wash with tepid not hot water, and do not over-scrub (all these things make itching worse). Pat dry. ...Read more

New bumps after Rx: Scabies treatments often contain a high percentage of alcohol which can be very drying to the skin.

What happens to me if I apply a second treatment of permethrin cream before the 2 weeks recommend? I did one last night and want another now! Help me

Not needed: Assuming your treatment was for scabies, even though a second treatment this soon would not be harmful, it also would be of little value. Treatment with Permethrin does not immediately cure the itch of scabies. It usually takes at least two weeks for the itching to subside. Meanwhile treatments for the itching such as antihistamines or anti-itch lotions such as sarna lotion should help. ...Read more

Permethrin treatment: I', assuming this was used to treat scabies. The mite is killed and the eggs that are under the skin are disabled immediately after treatment. However, the rash is a different matter. Part of the rash is caused by the inflammation of the skin in response to the foreign object of the eggs and mites. It takes weeks after treatment to get rid of residual inflammation after treatment and thus the rash ...Read more

How long until I can get in the bed with my girlfriend after my first treatment of permethrin for scabies?

Wrong question: It is very important that BOTH of you be treated for scabies at the same time, even if she has no symptoms. Every other contact and every other person in your home must be treated, even if assymptomatic. From the time of initial infestation to the beginning of itch is typically 2 to 3 months.

Still quite itchy 1 week after 2nd dose of permethrin. Should I see doc now or wait a bit longer? Itch does seem to be less than before 1st treatment.

Itching after scabie: Scabies treatments often contain a high percentage of alcohol which can be very drying to the skin. All of the little bumps are remnants of where the mite lived in skin. Hypoallergenic soaps and lotions which are pH balanced will help the skin recover more quickly, and reduce the itching that can last up to two weeks after treatment. ...Read more

Got treated for scabies, put permethrin from the neck down last night, but woke up with itchy bites on my side. I think its bites or is from treatment?

Bites: Keep using the treatment as stated by your doctor, also you should use hot, soapy water to wash all clothing, towels and bedding you used. Dry with high heat. Dry-clean items you can't wash at home. Consider placing items you can't wash in a sealed plastic bag and leaving it in your garage, for a couple of weeks, this will starve the mites. Treatment will take awhile. ...Read more
