Is Fas-3 Kit Safe To Use?

Hello Doctor, I was suffering from cold/cough/thorat infection/fever and was taking novaclox for 3 days 1-1-1, I also took Azilide 500mg for further 3days (0-0-1) as the infection did not subside. I have also been suffering from severe itching in the vaginal area along with creamish discharge along with ting of blood with no odour or fowl smell. I went to my doctor who prescribed me fas-3 kit. is this safe doctor? plz help. is there something serious? My age is 29yrs. did not have any sex since 3-4 months.
