Drug Interactions: What you should know before Administering Medications
It’s another toxic day at the hospital. Gina is bombarded by tons of things to do and she just couldn’t wait for the shift to end. It’s now time to administer due meds of her patients. While preparing the medications, she encounters a drug that she hasn’t encountered before. Should she check it in the drug book? Or should she just carry on administering it without checking so as to save time? She finds herself in a dilemma as she weighs her options. Which is more important? What should she decide on?
Understanding drug interactions
In nursing, we are always reminded of the importance of assessment, double-triple checking and many more. Working in a profession that deals with lives of people, a single mistake can make even the gravest consequence. Thus, it is important that you check everything first before performing any procedure to your patient, such as checking the drug interactions first before you administer medications.
Drug interaction is defined a situation in which a substance (usually another drug) affects the activity of a drug when both are administered together. Other factors that may interact with the drug aside from another drug are food/beverages and conditions.
Drug-drug interactions happen when two or more drugs react with each other. They may cause the patient to experience an unexpected side effect. One example is mixing a drug you take to help you sleep (a sedative) and a drug you take for allergies (an antihistamine) can slow your reactions and make driving a car or operating machinery dangerous.
Drug-food/beverage interactions result from drugs countering with foods or beverages. One example is mixing alcohol with some drugs may cause you to feel tired or slow your reactions.
Drug-condition interactions may occur when an existing medical condition makes certain drugs potentially harmful. For example, if one has high blood pressure he/she could experience an unwanted reaction if he/she takes a nasal decongestant.
