Patient: I think I have a yeast infection. I have recently been taking amoxicillin for tooth ache and during this time I started to have itching and a white discharge from my vagina. I knew these were the symptoms of thrush so went to the pharmacy and purchased caneston duo. I took the pill 3 days ago and have been using the cream twice a day since then however I’ve not really seen any difference except the discharge is now a yellow colour. I haven’t been able to get an appointment with my doctor as they are fully booked and I’m worried it isn’t disappearing!
