Hydroxyzine (Atarax) Dosage for a 17-Year-Old with Anxiety

For a 17-year-old with anxiety, the recommended dosage of hydroxyzine (Atarax) is 50-100 mg daily in divided doses. 1

Dosing Guidelines

The FDA-approved dosing for hydroxyzine in anxiety is age-specific:

  • Adults: 50-100 mg four times daily
  • Children over 6 years (including adolescents): 50-100 mg daily in divided doses 1

For a 17-year-old patient, who falls into the adolescent category but is approaching adulthood, the following dosing approach is recommended:

  1. Initial dosing: Start with 25 mg three times daily or 50 mg twice daily
  2. Titration: Adjust based on response and tolerability
  3. Maximum daily dose: 100 mg daily in divided doses

Administration Considerations

  • Hydroxyzine can be taken with or without food
  • Divided doses (2-4 times daily) are preferred to maintain consistent anxiolytic effects
  • Evening/bedtime dosing may be emphasized if sedation is a desired effect to help with sleep

Efficacy for Anxiety

Hydroxyzine has demonstrated efficacy for generalized anxiety disorder:

  • Superior to placebo in reducing anxiety symptoms 2, 3
  • Effects typically begin within the first week of treatment 3
  • Maintains efficacy throughout treatment periods without developing tolerance 4

Side Effects and Monitoring

Common side effects to monitor in adolescents:

  • Sedation/drowsiness (most common, reported in 28% vs. 14% with placebo) 3
  • Dry mouth (14% vs. 5% with placebo)
  • Weight changes
  • Concentration difficulties

Important note: Sedation tends to be most prominent during the first week of treatment and often diminishes with continued use 3.

Advantages and Limitations

Advantages:

  • Non-habit forming (unlike benzodiazepines)
  • No withdrawal syndrome upon discontinuation
  • No evidence of dependency development 4
  • Can be used as needed or regularly

Limitations:

  • Sedation may interfere with school performance or driving
  • Limited long-term efficacy data specifically in adolescents
  • May not be sufficient for severe anxiety disorders

Alternative Options

If hydroxyzine is ineffective or poorly tolerated, consider:

  • SSRIs: First-line pharmacological treatment for persistent anxiety disorders in adolescents 5
  • Psychotherapy: Cognitive behavioral therapy (CBT) has strong evidence for anxiety in adolescents 5
  • Combination therapy: CBT plus medication may be more effective than either treatment alone for persistent anxiety 5

Clinical Pearls

  • Avoid combining with other CNS depressants which may increase sedation
  • Counsel the patient about potential drowsiness, especially when initiating treatment
  • Reassess efficacy after 2-4 weeks of consistent use
  • Consider as a short-term solution while implementing longer-term strategies like CBT
  • Monitor for paradoxical reactions (rare but possible in adolescents)

Remember that medication management should be part of a comprehensive treatment approach for adolescent anxiety that includes appropriate psychological interventions.
