Aspirin will take care of a headache, but it may have a secondary benefit of protecting the heart, too. Beta blockers treat hypertension and are also prescribed to reduce anxiety, such as stage fright. And while the antipsychotic drug aripiprazole (Abilify) is approved for the treatment of schizophrenia, it's also prescribed for substance abuse, obsessive-compulsive disorder and dementia.

Off-label prescription medications are meds that are repurposed to treat a medical condition different from the one approved by the U.S. Food and Drug Administration. Off-label could also mean a drug is being used in an unusual or atypical way, such as orally instead of intravenously. Treatments prescribed for longer than the recommended duration or at a lower or higher dosage, for example, are also considered off-label.
While it's not legal for pharmaceutical companies to promote or market a drug for a use not approved by the FDA, it is legal for pharmaceutical reps to inform health care workers about studies showing promise in off-label applications.

Let's take a look at what we're hoping to cure with antidepressants, aside from our depression.
