bladder infection
"I had to stop taking this (amoxicillin liquid) after it made my throat swell up and affected my breathing.  I strongly believe that it was the yellow colouring in the medication which caused this rather than the drug itself as I have had allergic reactions to Tartrazine on several occasions and I now read labels thoroughly.  I wish medications could be prescribed that do not have added colourings as a large number of people, like me, are allergic to several azo dyes."
