As a pharmacist-health services researcher, Dr Antoinette Coe studies how to improve medication use and safety.
Some of her motivation comes from personal experiences as a caregiver and helping family members keep track of their medications, which can get complicated.
Research suggests that half of medications prescribed for people with chronic diseases might not be taken correctly.
Dr Coe, an assistant professor of clinical pharmacy at the University of Michigan in Ann Arbor, United States, answered questions about how to prevent errors for The Experts Say, the American Heart Association News series that asks specialists to explain how they apply what they’ve learned to their own lives.
Her remarks below have been edited.
Some common problems people make are related to how they take their medication, such as forgetting to take it or not taking it at the right time; taking too much or too little; and taking medications that can interact with each other, including over-the-counter medications, herbal products and supplements.

Often, communication plays a large role.
For instance, when a healthcare professional counsels the patient on how to take their new medication in a way that is not clear, the patient may not understand the directions.
Older adults are at higher risk for medication problems.
They may have multiple chronic conditions, which can lead to complex medication regimens, leading to an increased risk for drug interactions or challenges with medication adherence.
Also, older adults may have changes in liver or kidney function, which can affect how the body metabolises and clears the medications from the body.
Vision or hearing impairments may lead to problems reading prescription labels or hearing instructions.
Arthritis may make it hard to open bottles.
Cognitive decline may make it harder for older adults to remember how or when to take their medications.
Medication costs may also be a large problem.
Heart medications can be a source of medication-related problems, especially since cardiovascular conditions are so prevalent, particularly among older adults who are on multiple medications.
The medications may have side effects such as dizziness or fatigue, or need dosage adjustments that require monitoring and communication with their healthcare team.
A patient should understand what each medication treats, and how and when to take it, including whether or not to take it with food.
Some questions to consider for their doctor:
- What is this medication being prescribed for?
- What are potential side effects, and what should I do if they occur?
- How long do I need to take this medication?
- Is there anything I should avoid while taking this medication, such as food?
For their pharmacist, they can ask:
- How should I take this medication?
- Does this medication interact with any of my other medications?
- Are there any potential side effects I should be concern-ed about?
- What should I do if I miss a dose?
- Where should I store this medication: in the refrigerator or at room temperature?
One of the most important things is for people to have an accurate and up-to-date list of all medications they take, including prescription medications, over-the-counter medicines, herbal medications and supplements, and share it with their healthcare team.
Another helpful thing is to fill all their medications at one pharmacy if possible, so that the pharmacist knows all their medications and can check for drug interactions or duplications.
People should clarify with their pharmacist, doctor or other healthcare team member if any medication instructions are not clear.
Storing medications properly and keeping them out of reach of children is also important.
My advice is to make sure they have a list of all of their medications, dosages, how to take them, why they are taking them, and who prescribed their medication.
They should keep that list with them, such as in their wallet, to bring to all of their medical appointments.
And if they are having any issues with remembering to take their medications as prescribed, I suggest they consider using a medication pill box, a reminder alarm or an app on their phone. – By Michael Merschel/American Heart Association News/Tribune News Service
