"The pharmacy gave me the wrong pills." "The doctor prescribed something I'm allergic to." "No one told me about the interaction." "The dosage was wrong." These aren't rare events — they happen every day, and they can be deadly.
According to the U.S. Food and Drug Administration (FDA), medication errors cause at least one death every day and injure approximately 1.3 million people annually in the United States alone.[1] The Agency for Healthcare Research and Quality (AHRQ) reports that adverse drug events account for nearly 700,000 emergency department visits and 100,000 hospitalizations each year.[2]
"My father was prescribed a blood thinner while he was already on aspirin. He started bleeding internally and ended up in the ICU for a week. The ER doctor said if he'd had a list of his current medications, this could have been prevented."
— Angela R., daughter of medication error victim, age 45
Stories like Angela's are tragically common. The World Health Organization (WHO) has identified medication errors as a leading cause of avoidable harm in healthcare systems worldwide, estimating that the global cost associated with medication errors is $42 billion annually.[3]
A medication error is any preventable event that may cause or lead to inappropriate medication use or patient harm. These errors can occur at any stage of the medication process: prescribing, transcribing, dispensing, administering, or monitoring.
Research published by AHRQ indicates that prescribing errors account for nearly 50% of all medication errors, with dosing errors being the most common subcategory.[2]
An adverse drug event (ADE) is any injury resulting from medication use, including adverse reactions, overdoses, and harm from medication errors. While some ADEs are unavoidable (such as previously unknown allergic reactions), many are preventable through proper medication management.
The FDA estimates that ADEs cause more than 125,000 deaths per year in the United States, making them one of the leading causes of death nationwide.[1] The elderly are particularly vulnerable — patients over 65 are twice as likely to visit an emergency department due to an adverse drug event and seven times more likely to be hospitalized.[2]
Certain medications carry higher risks of adverse events when errors occur:

Get ProtectedThe good news is that many medication errors are preventable. According to the WHO, up to 50% of medication harm is avoidable.[3] Here are evidence-based strategies to protect yourself and your loved ones:
Keep an up-to-date list of all medications, including prescription drugs, over-the-counter medications, vitamins, and supplements. Include dosages, frequencies, and the prescribing physician for each medication.
Maintain a comprehensive list of drug allergies and adverse reactions you've experienced. Include the medication name and the type of reaction (rash, breathing difficulty, etc.).
When picking up medications from the pharmacy, verify the medication name, dosage, and appearance match what was prescribed. Don't hesitate to ask your pharmacist questions.
Medication tracking apps like MyMedicalCabinet can automatically check for drug interactions, send reminders for doses and refills, and store your complete medication history securely.
Always inform every healthcare provider about all medications you're taking. This is especially important when seeing specialists or visiting emergency departments.
Every new medication is checked against your list. Dangerous combinations trigger immediate alerts.
Your allergy list travels with you. When a prescription is in the same drug family, you'll know.
Scan prescription bottles to verify you received the correct medication before you take it.

Medication errors are extremely common. According to the FDA, medication errors cause at least one death every day and injure approximately 1.3 million people annually in the United States. The World Health Organization estimates that medication errors cost $42 billion globally each year.
The most common medication errors include: wrong dosage (either too much or too little), wrong medication dispensed, drug interactions not identified, medications given to patients with known allergies, omitted doses, and wrong route of administration. Prescribing errors account for nearly 50% of all medication errors.
You can prevent medication errors by maintaining an up-to-date list of all medications including over-the-counter drugs and supplements, keeping a record of drug allergies, verifying prescriptions match what you receive from the pharmacy, asking questions about new medications, and using a medication tracking app like MyMedicalCabinet that checks for drug interactions automatically.
An adverse drug event (ADE) is any injury resulting from medication use, including adverse reactions, overdoses, and harm from medication errors. According to AHRQ, ADEs account for nearly 700,000 emergency department visits and 100,000 hospitalizations annually. Many ADEs are preventable through proper medication management.
Those most at risk for medication errors include elderly patients taking multiple medications (polypharmacy), patients with chronic conditions requiring complex medication regimens, patients seeing multiple healthcare providers, those with cognitive impairments, and patients transitioning between care settings such as hospital to home.
If you suspect a medication error, contact your healthcare provider or pharmacist immediately. Do not stop taking prescribed medications without medical guidance. Report the error to the FDA MedWatch program. Document what happened, including the medication name, dose, time, and any symptoms experienced.
Being organized and informed is your best protection against medication errors.
