What Is a Controlled Medication?

A controlled medication, also called a controlled substance, is a prescription drug that is regulated by law because it has the potential for misuse, dependence, or abuse. These medications have legitimate medical uses but require careful prescribing, storage, monitoring, and disposal to ensure they are used safely.

Controlled medications are classified into different schedules based on their accepted medical use and potential for misuse.

Why Controlled Medications Matter

When used appropriately, controlled medications can effectively treat pain, anxiety, attention disorders, sleep disorders, and other medical conditions. However, improper use can increase the risk of dependence, overdose, and other serious health complications.

Examples of Controlled Medications

  • Opioid pain medications
  • Certain anxiety medications
  • Some sleep medications
  • Stimulants used to treat attention-deficit/hyperactivity disorder (ADHD)
  • Certain cough medications containing controlled ingredients

Safe Use of Controlled Medications

  • Take the medication exactly as prescribed.
  • Do not share medications with others.
  • Store medications in a secure location.
  • Keep track of doses taken.
  • Dispose of unused medications safely.

How Home Care Can Help

Home care professionals provide medication reminders when appropriate, encourage adherence to the prescribed schedule, monitor for possible side effects, observe for signs of medication misuse, and communicate concerns to the healthcare provider.

Home Care Tip

Never change the dose or stop taking a controlled medication without discussing it with your healthcare provider, as some medications require gradual tapering.
