Your home probably has some sort of pain relief medication, something to combat bouts of allergies, and maybe a few vitamins or supplements from the local health store. And then there are the prescribed medications, the ones you're taking daily and those that you take "as needed". But do you ever wonder how your medications work, what is the best time to take each, or how that pain relief tablet, those allergy meds, and prescription drugs interact when taken at the same time? Or how your newly prescribed antibiotic reacts with that glass of wine you had with dinner?
