Signs and symptoms of prescription drug abuse depend on the particular drug. Because of their mind-altering properties, the most commonly abused prescription drugs are:

  • Opioids, such as oxycodone (Oxycontin) and those containing hydrocodone (Vicodin), used to treat pain
  • Anti-anxiety medications and sedatives, such as alprazolam (Xanax) and diazepam (Valium), and hypnotics, such as zolpidem (Ambien), used to treat anxiety and sleep disorders
  • Stimulants, such as methylphenidate (Ritalin), used to treat ADHD and certain sleep disorders

When to see a doctor

Talk to your doctor if you think you may have a problem with prescription drug use. You may feel embarrassed to talk to your doctor about it — but remember that medical professionals are trained to help you, not judge you. Identifying prescription drug abuse as soon as possible is important. It's easier to tackle the problem early before it becomes an addiction and leads to more serious problems.
