Only rang because the online version said go to the Pharmacist, I reckon.
I had to contact the GP because my Psoriasis has gone crazy and all the OTC in the world couldn't fix it (plus the existing prescription stuff couldn't, either). I'd already gone through an OTC thing of making sure it wasn't infected/fungal, as there's no point taking up time when that'll be the first thing considered.
I used their app to (it was pretty shit, but I managed to find the right boxes to tick for Psoriasis) was triaged for a callback within a week, got phoned by the doctor later in the day, the prescriptions were sent to the pharmacy round the corner, I bought a prepayment certificate online, Mr D went and collected them. Sorted. When I had been in contact with somebody with what looked like Shingles at work, I called the GP about twenty minutes later (because of my steroids and Biologics), described the kid's rash to the GP when called back ten minutes later, they said it did sound like Shingles so I needed antivirals just in case, sent the prescription to the nominated pharmacy, I collected it on the way home from work. It works incredibly well - as long as you consider what is obviously GP and what is probably Pharmacist first.
