Uses for central-acting agents

Doctors prescribe central-acting agents to prevent, treat or improve symptoms in conditions, such as:

  • High blood pressure
  • Attention-deficit/hyperactivity disorder (ADHD)
  • Hot flashes
  • Drug withdrawal
  • Tourette syndrome

Side effects and cautions

These medications can have strong side effects, so they aren't commonly used. Side effects include:

  • Fatigue
  • Drowsiness or sedation
  • Dizziness
  • Impotence
  • Constipation
  • Abnormally slow heart rate
  • Dry mouth
  • Headache
  • Fever

Abruptly stopping use of some central-acting agents can cause a sudden, dangerous increase in blood pressure. Don't stop taking these medications without talking to your doctor.
