Canestan can cause a skin condion or allergic reaction, canestan dermatitis, it's also not the best for all fungal.issues
I guess the assistant was right not to sell it if it is not licensed for OTC use in any age group. And yes you should go to the doc if you have issues above that age just in case it is a side effect of something else. I imagine many will meanwhile get the treatment and if it clears up and you do go to the doc that will I guess confirm that it was thrush. The same.age limit without the doc prescribing is also for fluconazole. The doc needs to know about any underlying conditions that may be causing it, as others have said is it due to elevated blood sugars.
If.it is an after effect.of antibiotics, which I suffered from over the age of 60 I did use a packet that I'd already got just in case. If pr scribed by the doc you'd get the treatment free on prescription I guess
Fungal infections can be a difficult.thing to clear up.
Pharmacists won't dispense for an animal even if the vet says so, again not licensed, if they had said anything about the infant calpol the vet said to use with a little old dog, who was too little and too old for animal painkillers, it would have been for a baby. The dose was miniscule, you shouldn't use it without the vet saying the dose, that's why they weigh the animals when they come.in.
