It stands to reason: The more drugs you take, the greater your risk of skipping a dose, taking the wrong pill at the wrong time, or making another mistake.

That’s why it’s essential to get organized, says Michael Steinman, M.D., a professor of geriatrics at the University of California, San Francisco. That includes using such things as daily pill organizers, as well as taking these steps:

1. Keep a thorough log. Include all your pills—prescription and over-the-counter drugs, plus supplements. Note their brand and generic names, your dosage and schedule, the reasons you take them, the name of the prescribing physician, and special advice, such as whether you should take them with food or drink. Describe the shape and color of the meds. And write down your pharmacy’s phone number, any allergies you may have, and emergency contact info.

For help, download one of these printable templates: the Food and Drug Administration’s “My Medicine Record,” a “Personal Medicine Form” from the Institute for Safe Medication Practices, or “My Medicine List” from the American Society of Health-System Pharmacists.

2. Make copies. Store one in your wallet or purse, post another in your home, and give extras to a friend, family member, or caregiver. Review the log regularly with your doctors to make sure it’s up-to-date and to double-check for medication you might be able to eliminate.

3. Consider a pill-tracking app. We looked at 11 widely used ones. Most were difficult to use or didn’t do enough to protect your data privacy. But we found three freebies we think are worth a try: CareZone, Medisafe, and Round Health.

All allow you to add pills by name and dose, and set reminders for when to take them. And they alert you when it’s time to get refills. Medisafe alerts caregivers if you miss a med. Both CareZone and Medisafe also let you store doctor and pharmacy contact info. Medisafe can check for drug interactions.

All the apps we think are worth considering are HIPAA-compliant. That means that under the Health Insurance Portability and Accountability Act, your health information is protected by encryption and regular security updates. Still, read all privacy policies.

CareZone and Medisafe are available for Android and iOS (iPhone and iPad) devices; Round Health is available for iOS devices.
