Prescription drugs are medications that can only be obtained with the written order of a physician or other health care professional and are usually regulated by an authoritative or legislative body. “Rx” is an abbreviation often used for the word prescription.
Though consumers were once left in the dark as to the possible side effects of their medications, this is no longer the case. Thanks to the Prescription Drug Marketing Act of 1987 (PDMA) prescription medications by law, must carry warnings that provide consumers with information about side effects and other pertinent information. The PDMA was later modified by the Prescription Drug Amendments of 1992. The FDA—or Food and Drug Administration—is tasked with implementing and administering these laws and carefully reviews applications for new prescription medications, as well as all of the clinical trials associated with them.
