MEDICATION SAFETY: WHY TAKING MEDICINES THE RIGHT WAY MATTERS
Medication safety means using medicines correctly so they treat illness without causing harm from mistakes, side effects, or dangerous drug interactions. What is Medication Safety? Medication safety is the safe prescribing, dispensing, and use of medicines to reduce the risk of harm. Every medicine changes how the body works. Some medicines lower blood pressure, some fight infection, and others control pain or blood sugar. Because medicines affect the body’s systems, taking them incorrectly can cause serious problems. Medication safety aims to prevent these problems by making sure medicines are: The correct drug The correct dose Taken at the correct time Used for the correct condition Avoiding Process Overload Several processes happen in your body every time you take a medication. Absorption: the drug enters your bloodstream Distribution: it travels to different organs and tissues Metabolism: your liver breaks the medicine down Excretion: your kidneys remove any excess from the body If the wrong medicine or dose is taken, these processes can overload organs like the liver or kidneys. This can lead to side effects, drug toxicity, or poor treatment results. Avoiding Drug Interactions Medication safety also includes preventing drug interactions, which happen when medicines react with other drugs, supplements, or certain foods. For example, some medicines should not be taken together because they can raise blood pressure, cause bleeding, or affect heart rhythm. What Happens When You Don’t Practice Medication Safety Medication problems may feel different depending on the drug and the body’s reaction. You might notice that something simply feels “off.” Other signs indicating a medication error may be: Feeling tired or weak all of a sudden Daily tasks become harder to do Feeling dizzy, lightheaded, or unsteady on your feet Nausea or vomiting Skin rashes or itching Disrupted sleep, drowsiness, changes in your usual sleep pattern Confusion, having trouble concentrating Changes in appetite (either feeling hungrier than usual, or not) Fast or irregular heartbeat Headaches Swelling of the face, lips, or throat Trouble breathing Emotions scattered all over the place Some symptoms may appear quickly, others may develop after several days or weeks. Always tell your doctor about any new or unusual symptoms that begin after starting a medication. 4 Ways Medication Errors Can Happen Medication safety problems can occur at different steps in the healthcare process. From the moment a doctor writes a prescription to the time a patient takes the medicine at home, several small mistakes can lead to bigger problems. Prescribing Errors at this point happen when a doctor selects a medication and writes the prescription. Good doctors will consider many different factors before choosing a medication, such as the patient’s age, weight, medical history, allergies, and other medicines they are already taking. If any of these details are missed, a mistake can happen. For example: A patient allergic to penicillin may accidentally be prescribed an antibiotic from the same drug family. This could cause a serious allergic reaction. A patient with kidney problems may be prescribed a ‘standard’ dose of a particular medication. This might actually be too much for the patient’s weak kidneys to process properly, and the drug could build up in the patient’s bloodstream, raising the risk of side effects. A doctor may prescribe a drug that interacts with another medicine the patient already takes, such as certain antibiotics that should not be taken with blood thinners. Sometimes these errors occur because a patient forgets to mention a medication they take or because medical records are incomplete. How to avoid this medication error: Always take a complete list of all the medications you take, both prescription and over-the-counter, to every doctor’s visit. Your Medicare Annual Wellness Visit is a great opportunity to have a conversation about your medications with your doctor. Dispensing Dispensing happens at the pharmacy, where pharmacists prepare and provide medication to the patient. Although pharmacies have systems to prevent mistakes, errors can still occur. Common examples include: A pharmacist accidentally gives a medicine with a name similar to the one prescribed. For example, medications like hydralazine and hydroxyzine sound similar but treat completely different conditions. A label may contain instructions that are not very clear. For instance, “take twice daily” simply means the medicine should be taken two times in one day, but it does not explain when. One person might take both doses in the morning, while another might take them several hours apart. In many cases, doctors actually mean the medicine should be taken about 12 hours apart, such as once in the morning and once at night, so the drug stays at a steady level in the body. The pharmacy may give the correct drug but at the wrong strength, such as 50mg instead of 25mg. Pharmacists usually double-check prescriptions, but busy pharmacies and similar drug names can sometimes lead to mix-ups. How to avoid this medication error: Always match the medicine name and dosage on the label with your prescription. Ask a friend to double-check for you. Administration Medication mistakes at this point happen when the patient actually takes the medication. These errors usually happen at home, and often because instructions may be misunderstood or routines may be disrupted. For example: You’re supposed to take one tablet twice a day, but accidentally take two tablets at once. You forget you already took your pills for the day and take another dose “just in case”. A medication meant to be taken with food is taken on an empty stomach. This may cause stomach irritation or make the drug less effective. You stop taking an antibiotic early because you feel better, even though the full course is needed to clear the infection. For people who take several medications each day, it can be easy to mix them up, especially if the pills look similar. How to avoid this medication error: Keep a daily medicine schedule or pill organizer, follow the prescribed dose and timing carefully, and double-check before taking each medication. Monitoring After starting you on any medication, your doctor will monitor how well it
