While you are taking it

Things you must do

Side effects

Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking ACTACODE.

ACTACODE helps most people, but it may have unwanted side effects in some people, especially in elderly patients or those with underlying disorders.

After taking it


Keep ACTACODE in a cool dry place, protected from light, where the temperature stays below 30°C.
