Drug Safety Information
Medicines cure infectious diseases, prevent problems from chronic diseases, and ease pain. But medicines can also cause harmful reactions if not used correctly. Errors can happen in the hospital, at the doctor's office, at the pharmacy, or at home. You can help prevent errors by:
- Knowing your medicines. Keep a list of the names of your medicines, how much you take, and when you take them. Include over-the-counter medicines, vitamins, and supplements and herbs. Take this list to all your doctor visits.
- Reading medicine labels and following the directions. Don't take medications prescribed for someone else.
- Taking extra caution when giving medicines to children.
- Asking questions. If you don't know the answers to these questions, ask your doctor or pharmacist.
- Why am I taking this medicine?
- What are the common problems to watch out for?
- What should I do if they occur?
- When should I stop this medicine?
- Can I take this medicine with the other medicines on my list?
6 Tips to Avoid Medication Mistakes
- Find out the name of your medication. Rather than simply letting your doctor write a prescription and send you on your way, be sure to ask the name of the medication. “This way you’ll notice if the pharmacy gives you something different,” says Cindi Fitzpatrick, BSN, a registered nurse and a consumer safety officer in FDA’s Center for Drug Evaluation and Research. “Also, every time you receive a refill, look at the medication before you leave the pharmacy to make sure it looks the same as what you had before. Is it the same color, size, shape, and texture? Is the packaging the same? If anything about the medication seems different, ask the pharmacist about it.”
- Ask questions about how to use the medication. “It’s important to choose a doctor and pharmacist that you feel comfortable with so that you can freely ask questions,” Fitzpatrick says. Some good questions to ask: What should I do if I forget a dose? Should I take this medication before, during, or after meals? What should the timing be between each dose? What side effects might I have? When should I contact my doctor or pharmacist if I have certain side effects? Are there any other medications, food, or activities that I should avoid while using this medication? Should the medication be stored in the refrigerator or at room temperature? Take notes or ask your doctor to write down instructions or other information that is important to know about your medication or condition to help you remember.
- Know what your medication is for. Stephen Setter, Pharm.D., associate professor of pharmacotherapy at Washington State University in Spokane, says one of his patients mistakenly thought her glaucoma medication was for treating headaches. “So she was taking her eye medication only when she had a headache, but she should have been taking it every day to treat her eye disease,” Setter says. It’s important to understand your medication because you are more likely to use it correctly, more likely to know what to expect from the medication, and better able to report what you are using and problems to your doctors and pharmacist.
- Read medicine labels and follow directions. Before you use any medication, you should know when to use it, how much to use, and how long to use it. Be sure to read the medication label every time. In the middle of the night, you could accidentally put drops for your ears into your eyes or give your older child’s medicine to the baby if you’re not careful about checking the label. “Use the measuring device that comes with the medicine,” suggests Fitzpatrick. “If you don’t have a medicine device for measuring your liquid medicine, ask for one at the pharmacy.” Also, read the patient medication information that comes with your prescription thoroughly before using your medication.
- Keep all of your health care providers informed about your medications and dietary supplements (including vitamins and herbals). Make it a habit of showing your list of medications to all your health care professionals at every visit to the doctor, the pharmacy, and the hospital. Include on the list all your prescription and over-thecounter medications, and dietary supplements, including vitamins and herbals. Keeping all of your health care professionals informed about everything that you use will help ensure that you do not use two medicines with the same active ingredient or use anything that will interact with something else you are using. Some doctors work with their patients to do a “brown bag checkup.” This involves putting all of your prescription and over-the-counter medications into a paper bag and bringing them into your doctor’s office to be checked by your doctor. Include your dietary supplements and herbals too. “This should be done every year and preferably more often,” says Douglas Paauw, M.D., professor of medicine at the University of Washington in Seattle. “Some of my patients do it at every visit.”
- Keep the list of your medications with you at all times and let a loved one know. Keep a list of your medications and dietary supplements with you at all times, such as in your wallet or purse, and keep a copy in your home. Share a copy of the medication list with a family member or friend, or let them know where you keep the list. In an emergency, that person will be able to inform your doctors of the medications and dietary supplements you use.
Check Your Medicines: Tips for Using Medicines Safely
- Bring a list or a bag with ALL your medicines when you go to your doctor’s office, the pharmacy, or the hospital. Include all prescription and over-the-counter medicines, vitamins, and herbal supplements that you use. If your doctor prescribes a new medicine, ask if it is safe to use with your other medicines. Remind your doctor and pharmacist if you are allergic to any medicines.
- Ask questions about your medicines. Ask questions and make sure you understand the answers. Choose a pharmacist and doctor you feel comfortable talking with about your health and medicines. Take a relative or friend with you to ask questions and remind you about the answers later. Write down the answers.
- Make sure your medicine is what the doctor ordered. Does the medicine seem different than what your doctor wrote on the prescription or look different than what you expected? Does a refill look like it is a different shape, color, or size than what you were given before? If something seems wrong, ask the pharmacist to doublecheck it. Most errors are first found by patients.
- Ask how to use the medicine correctly. Read the directions on the label and other information you get with your medicine. Have the pharmacist or doctor explain anything you do not understand. Are there other medicines, foods, or activities (such as driving, drinking alcohol, or using tobacco) that you should avoid while using the medicine? Ask if you need lab tests to check how the medicine is working or to make sure it doesn’t cause harmful side effects.
- Ask about possible side effects. Side effects can occur with many medicines. Ask your doctor or pharmacist what side effects to expect and which ones are serious. Some side effects may bother you but will get better after you have been using the medicine for a while. Call your doctor right away if you have a serious side effect or if a side effect does not get better. A change in the medicine or the dose may be needed.
