Question: Two weeks ago I went to the doctor because of itchiness and a rash on my arm. The doctor said it could be scabies. I was prescribed permethrin. I used permethrin cream , but I used over 30 grams . I used almost the whole 60 gram bottle. I didn't realize this was more than the average dose. I was initially more itchy after I used the cream than before I was prescribed the cream. Now the itchiness has gone down. However today I was caught in the rain and the itchiness came back and I noticed some red blotches on my skin .

Brief Answer:
antihistamine and permethrin

Detailed Answer:
Hello
Thanks for the query.
There was response to permethrin this suggests that you had scabies.
Usually a single application of permethrin is enough to cure , however sometimes the itch might remain for a month.
Please take an antihistamine tablet and apply permethrin again after 15 days of initial application.
This will help in eradication of scabies.
Hope this helps.
Let me know if you have any other doubts.
Thank you

I have been having a troubling skin condition that has been diagnosed as scabies. I have been prescribed Permethrin 5% twice, which helped temporarily, but the symptoms always return afterwards. I have small white and red worm like objects all over me. They are particularly bad in vagina, on nipples, hands, feet, butt, back, ears, lips, and nose. I can feel them moving at times, but I m hopeful that things have improved bc I feel them less often now. They cause a crawling, itchy sensation at night that keeps me awake. There have also been random swollen areas on me which seem to be disappearing. There was one on my left earlobe, above my eye, on my neck, and under my toe. My vagina also had a blue/grey color on the left side which has slowly disappeared. After the permethrin my skin seems to be shedding in white pieces. Every time I use the bathroom more and more come off. I m just worried this may not be scabies because the symptoms still remain and the small white threads seem to keep coming off and I want it to stop. Not sure it whatever it is is dying, or growing. I have also been taking vitamins, using Black African soap when showering, and using dicatemous earth on skin. This condition has also caused several open sores on my skin and also swollen pimple like eruptions along my hairline. Thanks for any help-I m just hoping someone can figure out this mystery.

My grandma got some kind of contagious bugs that can t be seen about 10 years ago. She transferred them to my parents and sister by being in their home, cars, touching, etc. They used permethrin, dandruff shampoo, etc. If you got to them right away you could wash them away with a shower and washing your clothes. However they spread through my parents house where my sister lives and she can t get rid of them. My mom sent a fur trimmed coat over here 5 years ago and it stayed in the closet until I put it on March 23, 2014. I felt all itchy and was worried I had bugs but my sister said she didn t think the bugs could live 5 years. She and my parents knew they could live a couple of years on washed blankets that were stored away in a garbage bag because they had gotten infected that way. Anyway I for sure have them from the coat and it s been 1 month. My other sister caught them from me 3 weeks ago. My house and car keep re infecting me even though we steam everything we can all the time. I ve used permethrin 31/2 tubes and AM VERY SICK FROM IT. I just got re infected on Easter by running the vacuum the 1st time since the initial cleanup. My family has misled me on what kills them like vinegar,dandruff shampoo, hair dye and cattle spraying my house and car. Help! What can live w/o a host that long. I feel as though I have resistant Norwegian scabies but everything says they can only go 36 hours w/o a host. Can they feed off of shed skin cells and off the fur ruff leather? How do I know what they are and how do I eradicate them from all my papers, books, and every nook and cranny?

We were just moving into a new apartment and my girlfriend's daughter's boyfriend was helping us move things in for several days. About 76 hours ago, before my girlfriend took him home for the night I remember him telling me he was itchy. about 15 hours after that, 67 hours ago she saw him at a local store picking up medication. When she asked what it was he apparently said, "oh, my doctor said I've got chiggers or something" and she looked at the medicine he was prescribed and called me at work to look it up. The medication was Permethrin Cream, 5%. I looked it up and found out it was for scabies treatment. Within the next day, he was apparently very badly broken out; within the next day and a half following that his girlfriend, my girlfriend's daughter with whom he's had considerable contact with, was broken out and my girlfriend had complained the night before had an itchy bump on her hip. That evening my girlfriend and her daughter went to the doctor and were tentatively diagnosed with also being infested with scabies. A skin scrape was done on each but the labs haven't come back yet as it was a Thursday and they were told it would be at least 3-4 days before the lab results came back. Both have lived in the same apartment since the news and have been in contact with many things in the apartment. Since it was immediately after/during the move-in many thing were still yet unpacked. A lot of the large furniture had been moved around (many times to see how it looked) by the boyfriend and two other people at the same time, as well as me and my girlfriend separately on the last occasion (the one he told me he itched badly as he left). For three nights I slept with my girlfriend there. The night before they went to the doctor we had about 20 minutes contact where she manually stimulated me with lubrication and held each other off and on throughout the night. I was home very little after the initial move to help move things around and touched very few things after I got home late at night after waking up, but I did move the furniture (suede-like cover) and only wore clothes that the original infested person did not touch. There were, however, things (clothes and otherwise) in our bedroom he did carry that were on the carpet. I showered in a hot shower, as I always do, every morning before and after this became evident. As soon as I found out I have never returned to the apartment, have not had any physical contact with my girlfriend or anyone else for that matter. I am still showing no signs and used about a quarter tube of Permethrin cream on myself the day we all found out. I'm staying at my parents' house at the time, as the doctor my girlfriend saw advised, for a week or longer. I still can't really tell any signs but am getting ready to give myself a second treatment of the Permethrin cream as I was not aware I should wear full covering clothing and not wash it off for 24 hours. I applied the cream fairly thinly except my hands, arms, feet, ankles and genitals (as we had had prolonged contact at that point the night before). My girlfriend has sprayed things in the apartment down with anti-lice spray after vacuuming but has just nearly three days later gotten to wash all the clothes that were on the floor in bunches of hangers because they were not yet put away. Mine have been washed in hot water and dried on high heat, as hers have (considering neither of all have been done yet); mine have been delivered to me without her ever touching them (had her wear long rubber gloves) and I have also washed and dried them at my parents' house without me ever touching them. I have never had scabies before and read that symptoms may take 4-6 weeks to manifest. My girlfriend and her daughter have both had them within the last year for the first time and have manifest symptoms soon after exposure. What are my chances of being infested, infesting my immediate family (with which I've had fairly minimal contact now) and what is my best course of action? -- Thank You for Your Advice -- Travis
