What psych meds (psychiatric medications) are used to treat racing thoughts?

Psychiatric Medications for Racing Thoughts

SSRIs (Selective Serotonin Reuptake Inhibitors) are the first-line medication treatment for racing thoughts, particularly when these symptoms are associated with anxiety disorders. 1, 2

First-Line Medications

SSRIs

SSRIs work by inhibiting presynaptic reuptake of serotonin, increasing serotonin availability at the synaptic cleft. This helps modulate fear, worry, and stress while facilitating cognitive processing of emotions 1.

• Recommended options:

  • Fluoxetine: Start 10mg daily, increase to 20-40mg daily
  • Sertraline: Start 25-50mg daily, target dose 50-200mg daily
  • Fluvoxamine: Start 50mg twice daily, maximum 150mg twice daily
  • Citalopram: Start 10mg daily, increase to 40mg daily
  • Paroxetine: Start 10mg daily, increase to 40mg daily 2

• Dosing considerations:

  • Begin with lower doses and titrate slowly using increments of initial dose every 5-7 days
  • Full therapeutic trial requires 4-8 weeks
  • Significant improvement may be observed within 2 weeks 1, 2

• Common side effects:

  • Dry mouth, nausea, diarrhea, headache, sexual dysfunction
  • Initial activation symptoms (nervousness, insomnia) may predict good response 3, 4

Second-Line Medications

SNRIs (Serotonin-Norepinephrine Reuptake Inhibitors)

SNRIs inhibit reuptake of both serotonin and norepinephrine, which can be particularly helpful when racing thoughts are accompanied by significant anxiety 1, 5.

• Options:

  • Venlafaxine: Start low (37.5mg daily), increase gradually to 75-225mg daily
  • Duloxetine: Start 30mg daily, increase to 60-120mg daily
  • Desvenlafaxine: 50-100mg daily 5

• Considerations:

  • SNRIs have an ascending dose-response curve (unlike SSRIs' flat curve)
  • Higher doses activate noradrenergic effects
  • Monitor for blood pressure elevation at higher doses 5

Mood Stabilizers

When racing thoughts are associated with bipolar disorder or severe agitation:

• Options:

  • Lithium: First-line for bipolar disorder (approved down to age 12) 1
  • Valproate (Depakote): Initial dose 125mg twice daily, titrate to therapeutic blood level (40-90 mcg/mL) 1
  • Carbamazepine: Initial dose 100mg twice daily, titrate to therapeutic blood level (4-8 mcg/mL) 1

• Monitoring:

  • Regular blood level monitoring
  • Liver function tests and complete blood count as indicated 1

Third-Line/Adjunctive Medications

Atypical Antipsychotics

For severe racing thoughts with psychotic features or treatment-resistant cases:

• Options:

  • Risperidone: Initial dose 0.25mg daily at bedtime, maximum 2-3mg daily
  • Olanzapine: Initial dose 2.5mg daily at bedtime, maximum 10mg daily
  • Quetiapine: Initial dose 12.5mg twice daily, maximum 200mg twice daily 1

• Cautions:

  • Use low doses to minimize side effects
  • Monitor for metabolic effects (weight gain, lipid abnormalities)
  • Extrapyramidal symptoms may occur, particularly at higher doses 1

Anxiolytics

For short-term management of severe racing thoughts with anxiety:

• Benzodiazepines:

  • Lorazepam: 0.5-1mg up to four times daily as needed (maximum 4mg/24 hours)
  • Use with caution due to risk of tolerance, dependence, and cognitive impairment 1, 2

• Non-benzodiazepine options:

  • Buspirone: Initial dose 5mg twice daily, maximum 20mg three times daily
  • Takes 2-4 weeks to become effective, useful for mild to moderate symptoms 1, 2

Treatment Algorithm

1. Initial assessment:

   • Determine if racing thoughts are associated with anxiety, bipolar disorder, or other conditions
   • Rule out medical causes and substance use

2. First-line treatment:

   • For anxiety-related racing thoughts: Start with an SSRI (sertraline or fluoxetine preferred)
   • For bipolar-related racing thoughts: Start with lithium or valproate

3. Monitoring:

   • Weekly assessment for first 4 weeks
   • Evaluate response at 4-6 weeks
   • Monitor for side effects, particularly activation symptoms and suicidal ideation

4. If inadequate response after 6-8 weeks:

   • Switch to a different SSRI
   • Consider adding buspirone
   • Consider an SNRI

5. For treatment-resistant cases:

   • Consider augmentation with atypical antipsychotic
   • Consider combination therapy (SSRI + mood stabilizer)

6. Maintenance:

   • Continue effective medication for at least 9-12 months
   • Taper gradually when discontinuing (over 10-14 days) to avoid withdrawal symptoms 2

Important Considerations

• Medication selection should be guided by:

  • Symptom profile (anxiety vs. bipolar features)
  • Previous treatment response
  • Side effect profile
  • Comorbid conditions

• Common pitfalls to avoid:

  • Inadequate dosing or duration of treatment
  • Abrupt discontinuation
  • Failure to recognize bipolar disorder (can worsen with antidepressant monotherapy)
  • Excessive polypharmacy

• Special populations:

  • Elderly: Start with lower doses (half the standard starting dose)
  • Patients with substance use history: Avoid benzodiazepines
  • Young adults: Monitor closely for suicidality with SSRIs 2, 4

Racing thoughts often respond well to medication treatment, with most patients experiencing significant improvement within 4-8 weeks of starting appropriate therapy.
