Questions about this ingredient

  • QCan I take pain relievers with caffeine on days when I drink coffee?

    Caffeine found in coffee and medications are the same substance, so consuming them together can lead to an overlap in quantity. As it stimulates the central nervous system, the awakening effect may be felt more intensely. If you are usually sensitive to caffeine or consume a lot of coffee, please consult with a pharmacist.
