ANNOUNCER: Sometimes the effects of medicines must be monitored. Safety item five is: Check whether you need laboratory tests.
DAVID BATES, MD: Lab tests are important for a whole variety of medications now, and it's hard for physicians to remember to do all the testing that makes a difference.
Carolyn Clancy, MD: There are a number of medications that are incredibly important in terms of keeping people healthy or helping them prevent bad outcomes like strokes, blood clots, and so forth, but those medications also require careful monitoring.
ANNOUNCER: Another factor contributing to prescription drug errors is: The prescription.
GREGG S. MEYER, MD: Again, one of the most important things patients can do is they can ask questions. If you do get a handwritten prescription, look at it and read it. If you're having trouble understanding what it says, it's likely the pharmacist may have that same trouble. Ask for another copy of it; ask for one to be printed out, because that can really make a difference.
ANNOUNCER: Medicines can be powerful aids to help keep us well. But experts remind us, using them correctly requires checking and double checking, on the part of the doctor, the pharmacist, and the patient.
