We have tried lice shampoos such as banlice and pyrenel. My son has used Quellada scabies treatment which was advised by a doctor. He covered himself head to toe with this for several days. On Friday he brought benzylkonium chloride with which he sprayed throughout the house (mainly carpeted areas). We have had no other pest treatment in the house as we were not sure what we were treating. In the beginning my son would only have relief for a few days at the most. Now it seems that nothing is working for longer than a few days. My 21 year old son experiences the symptoms but not as severe. He also went through a period where he would spray his body with metho or kerosene. My husband and i have both checked for lice and treated a few times with the pyrenel foam. I had one period around 6 weeks ago where my scalp was itching for a day but once treated it settled down, however i used a nit comb and found no evidence of lice or nits. We have been boiling or treating clothing and bedding for weeks.
Use of Permethrin(Nix/Rid),Malathion(Ovide)as local treatment for headlice at weekly intervals will help kill the lice,the nits or lice eggs will need to be cleared with a fine toothed lice comb.The use of local Ivermectin (sklice), will help clear the headlice with no need to clear the nits.It is used as a single application ,applied locally on the scalp for 10 minutes.Resistant lice can be cleared by a oral drug Ivermectin as a single dose which will need to be repeated after one week. Apart from medication it is important to identify the source of reinfection.All household members having the problem will need to be treated simeltaneously. Laundering/washing with hot water of bedsheets/blankets,scarves,hats,pillow cases,towels will eliminate any local reinfection sources.Vacuuming and cleaning floors and furniture will remove any infected hairs.
Other causes of itching like intestinal endoparasites ,food allergy,chemical or nickel allergy will need to be excluded and treated.Diseases like autoimmune disease,blood disorders ,chronic liver diseases will also need to be ruled out by your doctor/PCP.Body lice will also respond to Ivermectin therapy.
Thank you for the answer but at this stage we don't think it is headlice. We have done most of the treatment you have described with little success. Combing with the nit comb after treatment does not find any lice or eggs. The crawling is felt all over the body. As for the laundering, the washing machine rarely stops and we have tubs and buckets all over the place with treated clothing. Can you please suggest anything else and could this be a skin mite?
Mites are occasionally found in houses and may attack humans in the absence of rodent,bird or insects who are their usual hosts.If there is a pet in the house,zoonotic diseases may be relayed from the dog/cat.Eliminating any allergic problem to common allergens will help.Ivermectin orally is effective in body louse,scabies and similar infestations.A oral course of mebendazole/Albendazole will eliminate any larvae migrans secondary to intestinal parasites.Atopic dermatitis or eczema may need to be identified and treated apart from systemic diseases.
Thank you for your response. Do we need to get a prescription for the mebendazole or ivermectin. We are currently in Victoria Australia?
