Medications make a difference — generally a positive one — in the lives of many people. Insulin keeps blood sugar under control, cholesterol-lowering drugs can reduce the chances of having a heart attack, and thyroid medication can restore a normal hormone level. These are but a few examples.

At the same time, all drugs carry side effects, and can interact with other medications. For many medications, one or more side effects affect balance. And that can increase your chances of taking a fall. How? According to the Centers for Disease Control and Prevention, common problems include vision changes, dizziness or lightheadedness, drowsiness, and impaired alertness or judgment. Some medications may damage the inner ear, spurring temporary or permanent balance disorders.

How do I know if this is a problem for me?

Some of the commonly prescribed medications that can affect balance include:

• antidepressants
• anti-anxiety drugs
• antihistamines prescribed to relieve allergy symptoms
• blood pressure and other heart medications
• pain relievers, both prescription and nonprescription
• sleep aids (over-the-counter and prescription forms)

Sometimes the problem isn’t a single drug but the combination of medications being taken together. Older adults are especially vulnerable, because drugs are absorbed and broken down differently as people age.

If you are concerned about how your medications may be affecting your balance, call you doctor and ask to review the drugs you’re taking, the dose, and when you take them. It is never a good idea to just stop taking a medication without consulting your health care provider first. Doing so can create even more health risks.
