Hi. I was just diagnosed with type A flu. The dr. I saw prescribed tusselin perles. I have a cough medicine with codeine in the house. I get that the former med is non narcotic. However. I am afraid of side effects from a new medication and know that I don't have a negative reaction with the codeine med. I am trying to decide which is better.
