Common concerns from people taking Allegra (fexofenadine)

Final section. Do you want to return to drug navigation?
Food
  • Some forms of Allegra (fexofenadine) contain the amino acid phenylalanine, found in the artificial sweetener aspartame. People who have phenylketonuria (PKU) can't break down phenylalanine, which then builds up and causes serious medical problems. If you have PKU, check to see which medications you can use.
Kidneys and liver
  • The dose needs to be adjusted for people with kidney problems.
