The most common side effect of topical corticosteroid use is skin atrophy. All topical steroids can induce atrophy, but higher potency steroids, occlusion, thinner skin, and older patient age increase the risk. The face, the backs of the hands, and intertriginous areas are particularly susceptible. Resolution often occurs after discontinuing use of these agents, but it may take months. Concurrent use of topical tretinoin (Retin-A) % may reduce the incidence of atrophy from chronic steroid applications. 30 Other side effects from topical steroids include permanent dermal atrophy, telangiectasia, and striae.
I have suffered from mosquito and bee allergies all my life but ive never had a problem with fleas, and what I’ve found that works and doesn’t hurt to apply when the sting swells too big is solarcaine it’s a sun burn topical anesthetic spray that numbs the area. I don’t know if this is the best way to treat a bit but there is no rubbing in and the spray is cold so you get the icy feel on the skin. In conjunction with that I take an antihistamine by mouth every 8 to 12 hours while the intense irritating itch occurs. The one a day has just stopped working for me. I am 17 but have been dealing with this all my life.
I really feel for your son, just thought another suggestion might help someone. Good luck with the control
