Hi, thanks for trusting Healthcare Magic.
I understand with your concerns, but you should not worry too much due to you've got treatment from a
dermatologist.
I do not know what the cream name is given by your dermatologist, but usually the doctor will give Permetrhin 5% or Scabisid for cases like this.
If the cream is Permetrhin 5%, you just use it for 1 day at night and the cream should stick for >8 hours. If the cream is Scabicid, use after an afternoon bath and may rinse it in the shower the next day. Giving the scabicid repeated two to three times with a lapse of two to three days.
Orally, to allevate the itching you can take levoctetrizine daily night times and oral intake of specific drug ovicidal.
For prevent re-infestation, clothes,bed sheets and linen must be laundered in hot boiling water. But I'm sorry I can not recommend a company near where you live, because we live in a different country.
Hope this information will be useful for you.
Good luck
