Medication errors refer to mistakes in prescribing, dispensing and giving medications. They injure hundreds of thousands of people every year in the United States. Yet most medication errors can be prevented. How can you protect yourself and your family?
One of the best ways to reduce your risk of a medication error is to take an active role in your own health care. Learn about the medications you take — including possible side effects. Never hesitate to ask questions or share concerns with your doctor, pharmacist and other health care providers.
Medication errors are preventable events due to the inappropriate use of medications. Medication errors that cause harm are called preventable adverse drug events. If a medication error occurred, but didn't hurt anyone, it's called a potential adverse drug event.
An example of a medication error is taking an over-the-counter product that contains acetaminophen (Tylenol, others) when you're already taking a prescription pain medicine that contains this exact ingredient. This mistake could cause you to take more than the recommended dose of acetaminophen, putting yourself at risk of liver damage.
Another example of a possible medication error is taking a depression medication called fluoxetine (Prozac, Sarafem) with a migraine drug called sumatriptan (Imitrex). Both medicines affect levels of a brain chemical called serotonin. Taking them together may lead to a potentially life-threatening condition called serotonin syndrome. Symptoms of the dangerous drug interaction include confusion, agitation, rapid heartbeat and increased body temperature, among others.
Medication errors can happen to anyone in any place, including your own home and at the doctor's office, hospital, pharmacy and senior living facility. Kids are especially at high risk for medication errors because they typically need different drug doses than adults.
Knowing what you're up against can help you play it safe. The most common causes of medication errors are:
Knowledge is your best defense. If you don't understand something your doctor says, ask for an explanation. Whenever you start a new medication, make sure you know the answers to these questions:
Your doctor can help prevent medication errors by using a computer to enter and print (or digitally send) any prescription details, instead of hand writing one.
Asking questions is essential, but it isn't enough. Your health care providers can follow a process called medication reconciliation to significantly decrease your risk of medication errors.
Medication reconciliation is a safety strategy that involves comparing the list of medications your health care provider currently has with the list of medications you are currently taking. This process is done to avoid medication errors such as:
Medication reconciliation should be done at every transition of care in which new medications are ordered or existing orders are rewritten. Transitions in care include changes in setting (such as being admitted or discharged from the hospital), health care provider or level of care.
Sharing your most up-to-date information with your health care providers gives the clearest picture of your condition and helps avoid medication mistakes.

"Don't ask, don't tell" is never a smart policy when it comes to medications and your health. Don't hesitate to ask questions or to tell your health care providers if anything seems amiss. Remember, you're the final line of defense against medication errors.
If despite your efforts you have problems with a medication, talk with your doctor or pharmacist about whether to report it to MedWatch — the Food and Drug Administration safety and adverse event reporting program. Reporting to MedWatch is easy, confidential and secure — and it can help save others from being harmed by medication errors.
