You were just prescribed a new medication. Is it compatible with other meds you’re taking? Or is there a possible reaction that would interfere with one of your other meds or otherwise affect your health? Doctors are not always on top of what you’ve been prescribed, especially if you have more than one physician. Besides, it’s been many years since they took a course in pharmacology.
Your doctor tries to watch out for you. So does your pharmacist. It doesn’t hurt, though, if you look out for yourself, as well.
AARP has an easy way to help you do that. Try their Drug Interaction Checker. Be safe.
