19 Aug What Happens If a Pharmacy Gives You the Wrong Medication?
Receiving the wrong medication from a pharmacy can be frightening, especially if you have already taken a dose. Pharmacy errors can happen for different reasons, including confusion between medications with similar names, incorrect labeling, or dispensing the wrong strength. If a pharmacy gives you the wrong medication, the first priority is to get professional medical guidance and avoid taking another dose until you know exactly what you received.
Understanding the role of a compounding pharmacy can also be useful when discussing customized medications, since compounded prescriptions may be prepared differently from standard commercially manufactured drugs. According to the FDA, compounded medications are not FDA-approved and may carry different risks than commercially manufactured drugs, making verification of dispensed medications especially important.
Do Not Take Another Dose Until You Verify It
If you notice that the medication does not look like what you normally receive, do not automatically assume that the pharmacy made an error. Generic medications can look different from one manufacturer to another while containing the same active ingredient. However, any uncertainty should be taken seriously. Compare the pharmacy label with your prescription and contact the pharmacist to confirm the medication, strength, and directions.
Contact a Pharmacist or Healthcare Professional
If you have already taken medication that you believe is incorrect, contact the dispensing pharmacy as soon as possible. Tell them the name and strength printed on the container, how much you took, and when you took it. A pharmacist can help determine the appropriate next step. Depending on the medication involved, you may simply need to monitor for symptoms, while other situations may require prompt medical evaluation. Do not attempt to cancel out the effects of a medication by taking another drug unless a healthcare professional specifically recommends it.
Pay Attention to Symptoms
A medication error may cause no immediate symptoms, but that does not mean it should be ignored. Possible effects depend entirely on the medication and the amount taken. Unexpected symptoms can include dizziness, unusual sleepiness, confusion, nausea, vomiting, changes in heart rate, or an allergic reaction. More serious reactions may also occur with certain medications. If you experience severe symptoms, difficulty breathing, loss of consciousness, seizures, or another medical emergency, seek emergency medical care immediately.
Contact Poison Control if Necessary
If someone accidentally takes the wrong medication, Poison Control can provide guidance based on the specific substance and circumstances. When contacting Poison Control, it helps to have the medication container available. You may be asked for the medication name, strength, amount taken, time of exposure, and information about the person who took it. In the United States, Poison Control can be reached at 1-800-222-1222, or you can use its online service for guidance.
Keep the Medication and Packaging
Do not throw away the medication bottle or packaging after discovering a possible error. The label can provide important information about the drug, dosage, instructions, and pharmacy. Keep the remaining medication available so a pharmacist, doctor, or poison specialist can identify what was actually dispensed. If possible, keep your original prescription information nearby as well. Also remember that a different-looking pill is not automatically evidence of a pharmacy mistake. Approved generic medications can vary in color, shape, and size.
Ask the Pharmacy What Happened
After your immediate health concerns have been addressed, speak with the pharmacy about the error. Ask what medication was dispensed, what medication was supposed to be dispensed, and what steps the pharmacy is taking to prevent the problem from happening again. You may also want to document the details, including the date, medication name, dosage, and any symptoms you experienced. If the mistake resulted in an injury or significant medical expenses, consider discussing your circumstances with a qualified attorney who handles medication-error or pharmacy-malpractice cases.
How to Reduce the Risk of Future Errors
Patients can take a few simple steps to catch potential problems early. When picking up a prescription, check the medication name, dosage, directions, and appearance before leaving the pharmacy. If something seems unfamiliar, ask the pharmacist to explain it. You can also keep an updated list of your medications and bring it with you to medical appointments and pharmacy visits. Taking a few minutes to verify your prescription can help identify a problem before you take the medication.
