I am 23 years of age and I was having burning sensation in my urinary bladder. When I had my ultrasound done it confirmed urinary tract infection. My doctor has prescribed me nitro-furantoin mono-mcr 100mg twice daily dosing for 3 days as antibiotic. I know its a heavy antibiotic and before taking it I want to know about the nitrofurantoin mono-mcr side effects? Can this medication be trusted in UTI? Anybody else tried it with success?
