Gemma Howarth is talking to pharmacy technician Vicky about a prescription she has brought in for her son Josh.

“I was sure it was impetigo and the doctor agreed,” says Gemma. “It’s exactly the same as when he had it a few years ago and his brother had it when he was young as well. But when I went to get the prescription, it’s for a completely different product. Do you think the doctor made a mistake? Video appointments are all well and good, but perhaps I misheard? We’ve always been given fusidic acid cream, which has worked very well, but this prescription is for hydrogen peroxide!”
