Reading a doctor鈥檚 handwritten prescription can feel like trying to understand a foreign language. Between confusing pharmacy abbreviations, complicated medical names and other bits of information, it’s natural for your eyes to glaze over after just a few seconds. Whether you鈥檙e a prospective pharmacy technology student looking to better understand the prescription process or a consumer trying to decode what your doctor writes on your prescription, this educational guide easily breaks down how prescriptions work.
Despite their confusing nature, medication labels contain important information about a prescription, so it鈥檚 necessary to have at least a fundamental grasp on what it all means. Remember, you can always ask your pharmacist or pharmacy technician to clarify anything you don鈥檛 understand.
Who Can Write Prescriptions?
Both federal and local laws give a wide range of different medical professionals the ability to write prescriptions. Physicians, physician assistants, advanced practice registered nurses, nurse practitioners, anesthetists, certified nurse midwives and clinical nurse specialists currently have the power to do so in all fifty states. In some states, clinical pharmacists can write prescriptions, as long as it is in collaboration with a physician or drug formulary.
Why Is It Important To Know My Prescription?
Understanding exactly what your prescription means is invaluable for a few different reasons. For starters, being clear on which medications you should take and which you should avoid can help you evade adverse drug reactions, which can occur when taking multiple medications. There are two million serious adverse drug reactions (also called ADRs) per year, which results in over 100,000 deaths. 82% of American adults take at least one medication, and 29% of all patients in the United States take more than five medications at a time. To put this into perspective, the rate of an ADR increases exponentially when patients take more than four medications.
Common adverse drug reactions caused by drug interactions
- Aspirin and Warfarin, when taken together, increase your risk of bleeding.
- Lithium and Diuretics can alter the levels of sodium in your kidneys.
- Oral contraceptives and rifampin, an antibiotic, can cause contraceptives to be less effective when taken at the same time.
What Goes Into A Prescription?
A standard medical prescription usually includes a few key pieces of information like the name of the drug, the strength and the recommended dosage. It will also include specific directions for how you should use it, the total quantity of the medication that is being prescribed and the number of authorized refills that you have before the prescription will need to be renewed.
What Do Those Prescription Abbreviations Mean?
The pharmaceutical abbreviations that physicians use are often based on a combination of Latin and prescription shorthand, to get important information across as quickly as possible, to save space and to make it more difficult for a patient to alter a prescription on their own. These medication abbreviations are broken down into a few different categories:

What About Generic Drugs?
According to the Food and Drug Administration, a generic drug is one that is comparable to a brand name medication in form, strength, route of administration, quality and more. Generic drugs are often 80 to 85% less expensive than their brand name counterparts. As a result, 80% of all prescriptions filled in the United States are for these generic medications.
