Nitrofurantoin
bladder infection
"After being prescribed Monurol (a single dose, powder satchet antibiotic) for a pretty nasty Bladder Infection, I had to go back to the doctor because I was still in serious pain. 

My family doctor prescribed Macrobid, and after taking ONE dose, I started to have relief. I'm pretty sensitive to medications, I usually get the full list of side-effects; headache, nausea, diarrhoea, but with Macrobid, absolutely nothing-not even the weird possible "darkening of urine". 

Believe me, I'm a big baby, I'd whine about anything, this medication was amazing."
