Medication dose, as well as information about the effectiveness and side effects of medication, is generally determined by studies done in relatively young, healthy people. This information may not apply to older adults because our bodies and how we process medications change with age. As we get older, our bodies react to drugs differently than when we were younger.

The aging process, along with medical conditions, often impacts the benefits and side effects of medications.

Drugs go on a complex journey through our body from the time we take our medications until they leave our body.

The aging process can affect how the medication is absorbed, used in the body and exits the body. Changes that decrease your body’s ability to break down or remove certain medications from your system may mean medications can stay in your body longer. So you may need a lower dose of the medication or a different medication that is safer. In most cases older adults need lower doses of medications than younger adults. You can start with a low dose of a medication, then slowly increase to the target amount to receive the same benefit and avoid side effects. This can be done by working closely with your healthcare provider.

Studies also show certain medications are less safe for older people, and it is important you work with your provider or pharmacist to use medications that are safe for your age.

When taking medications, it is important to make sure of the following:

—The correct medication is prescribed for the correct condition.

—The medication is right for you, your age and your conditions.

—You take the proper dose for the length of time your healthcare provider prescribes.
