Medicare Part D: The benefits and risks
The addition of prescription-drug coverage was Medicare’s biggest expansion since its creation
in 1965. Called Medicare Part D, it now provides more than 35 million elderly and
disabled enrollees with critical medications for modest out-of-pocket costs.
But since Part D began in 2006, prescribers and their use
of potentially risky drugs have not been
monitored by Medicare.
In 2010, thousands of health providers in Part D wrote prescriptions for drugs to seniors that the American Geriatrics Society says are potentially inappropriate. Some of the 20 most-prescribed drugs in this category and their side effects in older adults:
Type 2 diabetes drug can cause dangerously low blood sugar, other side effects.
Dizziness, fainting and falling; may cause slowed heartbeat.
May raise risk of breast, uterine cancer; doesn’t appear to protect women from heart disease or cognitive loss.
Sleepiness, increased risk of bone fractures.
May cause confusion, drowsiness, blurred vision, difficult urination.
Increased risk of stomach or intestinal bleeding, ulcers.
