Preventing Medication Errors at Home

Most home medication systems do not need to be complicated. Good lighting, one accurate list, clear labels, and a consistent double-check can prevent many common mistakes.

About your visit

3. A pharmacist can help check for duplicate medicines and interactions.

How confident are you about using a medicine list and asking medication-safety questions?

Privacy: no name, email address, birth date, diagnosis, medicine, provider, or caregiver-record entry is collected. An anonymous code on this device connects the starting and follow-up checks.

Use the five checks every time

Before the dose

  1. Right person: confirm who the medicine is for.
  2. Right medicine: match the label to the current list.
  3. Right dose: check the strength and amount.
  4. Right time: confirm when it is due and when the last dose was taken.
  5. Right way: follow directions such as with food, swallowed whole, inhaled, injected, or applied to skin.

Set up the home

  • Use one well-lit, quiet place to prepare medicines.
  • Keep each person’s medicines separate and in original labeled containers until a system is confirmed.
  • Store medicines away from heat and moisture and lock up opioids or other high-risk products.
  • Keep an updated list in the wallet and at home.
  • Use one pharmacy when possible so interactions and duplicates are easier to detect.

Common mix-ups to prevent

  • Taking an old medicine after it was stopped or replaced
  • Taking the same active ingredient in two brand-name products
  • Confusing look-alike bottles, pill colors, or family members’ medicines
  • Using a kitchen spoon for a liquid dose
  • Crushing or splitting a medicine that must remain whole
  • Repeating a dose because nobody recorded that it was given

When the plan changes

  • Compare the old and new lists after every hospital, emergency, specialist, or pharmacy visit.
  • Write down exactly what started, stopped, or changed.
  • Ask the pharmacist to explain unfamiliar wording and show you how to measure or use the medicine.
  • Remove discontinued products from the active supply and dispose of them safely.

If an error may have happened

Call 911 for trouble breathing, loss of consciousness, seizure, signs of stroke, or severe symptoms. In the United States, call Poison Help at 1-800-222-1222 for immediate, confidential guidance—even if symptoms have not started. Keep the container nearby and be ready to state the medicine, strength, amount, time, age, and symptoms.
