Prescription Drug Misuse

Reading this article

Topic pages summarize public health information in plain language. They may describe common causes and treatments in general terms; your own plan of care depends on your clinician’s exam, history, and tests. Use what you read here to prepare questions—not to start, stop, or change medications or to self-diagnose.

If you take a medicine in a way that is different from what the doctor prescribed, it is called prescription drug misuse. It could be:

  • Taking a medicine that was prescribed for someone else
  • Taking a larger dose than you are supposed to
  • Taking the medicine in a different way than you are supposed to. This might be crushing tablets and then snorting or injecting them.
  • Using the medicine for another purpose, such as getting high

Misusing some prescription drugs can lead to addiction. These include opioids, sedatives, tranquilizers, and stimulants.

Every medicine has some risk of side effects. Doctors take this into account when prescribing medicines. People who misuse these drugs may not understand the risks. The medicines may not be safe for them, especially at higher doses or when taken with other medicines.
