Medication errors—mistakes in prescribing, dispensing, taking or giving medications—impact hundreds of thousands of people a year. Some occur in a hospital or healthcare setting, others occur at home. Preventable medication errors can send patients to the emergency room, to the hospital, or worse, result in death.
Examples of medication errors that commonly happen at home include:
- Taking multiple medicines that contain the same “active ingredient.” For example, taking an over-the-counter (OTC) product that contains acetaminophen when you’re already taking a prescription pain medicine that contains acetaminophen.
- Taking or giving an incorrect dosage of a medicine, oftentimes the result of using a kitchen spoon rather than a metric measuring device
- Taking an incorrect medicine dispensed by a pharmacy due to sound-alike names or confusing medical abbreviations.
- Taking someone else’s medication instead of your own, which can result from multiple medicines for multiple users stored on the same location.
- Taking a medication on an empty stomach when it is supposed to be taken with food
While medical errors are generally accidental, medication misuse can sometimes be intentional. For example.
- Over use: taking more than prescribed or recommended dose by the healthcare provider or label. This can happen by accident—maybe you forgot you took your medicine, so you take it again. Or it can be intentional, like taking an extra dose of a prescription or OTC pain relievers.
- Under use: taking less than prescribed or recommended, missing or skipping doses either accidentally or intentionally, not filling an initial prescription or failing to get a refill.
- Not following instructions on the label.
- Taking medicines that are not prescribed for you.
Prevent Medical Errors With the Following Tips:
- When your healthcare provider writes you a prescription, make sure you can read it. If you can’t read the handwriting on the prescription, your pharmacist might not be able to either. Ask your healthcare provider about e-prescribing, in which your prescription is electronically entered and sent to the pharmacy of your choice.
- Ask for information about your medicines in terms you can understand—both when your medicines are prescribed and when you receive them at the pharmacy—so that you can take your medicine safely and avoid errors. (Check out this brief article: 10 questions to ask about the medicines you take)
- When you are being given a medicine at the hospital or picking up a medicine from the pharmacy, confirm it is medicine that your doctor prescribed. Studies show that the vast majority of medicine errors involved the wrong drug or the wrong dose.
- Ask your pharmacist for the best device to measure your liquid medicine. Special devices, like marked cups or oral plastic syringes, are available at most pharmacies and help to measure the precise dose.
- Make sure your doctor knows about any allergies and adverse reactions you have had to medicines. This can help you avoid getting a medicine that can harm you.
- Read about the side effects listed on the written information that comes with your prescription medicine. If you are familiar with the possible side effects that could occur, you can more quickly recognize if you are experiencing one and alert to your healthcare provider or pharmacist.
- Make sure that all of your doctors know all the medicines you are taking, including prescription and over-the-counter medicines, and dietary supplements such as vitamins and herbs.
Lack of prescription adherence can be considered America’s “other drug problem.” This can lead to unnecessary disease progression, disease complications, a lower quality of life, and even the possibility of premature death. Not taking your medicine as prescribed may lead you to experience longer or more serious illnesses. It may also lead to you not getting the full relief that the medicine is intended to provide.
Medication “non-adherence” or “non-compliance,” either intentionally or inadvertently, can include:
- Failing to initially fill a prescription
- Failing to refill a prescription
- Stopping a medication before the course of therapy is complete
- Taking more or less of a medication than prescribed
- Taking a dose at the wrong time
- Missing a dose completely
About 125,000 people die each year in the United States because of not taking medicine as directed. About one third of medicine-related hospital admissions in the United States are linked to non-adherence. Additionally, it costs the country nearly $300 billion each year in added costs for doctor visits, emergency room visits, hospital admissions and more medicine.
Explore ways to reduce medicine costs. Due to high prescription prices, people don’t fill their prescriptions. Or, they skip doses so the medicine lasts longer. Yet, there are programs that help you afford your meds. For example, prescription assistance programs provide free or low cost prescription medications.
- Keep things simple: Talk to your doctor or pharmacist about how to simplify your medication schedule. If possible, take your medicines at the same time each day.
- Work with one pharmacy: Use one pharmacy for all prescriptions and refills. This way the pharmacy can help you manage your refills and check for drug interactions.
- Coordinate prescription refills: Talk with your doctor and pharmacist to see if you can align refill dates. Then you can pick up all medications at the same time.
- Use a reminder tool: Use a printed pill reminder sheet or write down your medication schedule. This will help you keep track of what to take, when to take it, and special instructions like “take with food.” There are alerts on phones or computers. Some people use adherence packaging or “blister packs.” Some rely on weekly pillboxes to sort medicines by day or time of day. If you do this, keep the packaging to reference dosing information and other instructions. Also, pillboxes are generally not child-resistant so keep them up and away and out of sight of young children.
- Establish a routine: Try to tie your medication schedule to your daily activities.
