Target Dose of Venlafaxine for Adults with Depression or Anxiety Disorders

Pharmacokinetics and Dosing

• The therapeutic plasma concentration range for venlafaxine plus O-desmethylvenlafaxine (its active metabolite) is 195-400 ng/mL, according to the American Academy of Child and Adolescent Psychiatry 1

Formulation and Administration Considerations

• Venlafaxine extended-release (ER) formulation allows for once-daily dosing due to its longer elimination half-life, as recommended by the American Academy of Child and Adolescent Psychiatry 2, 3
• Immediate-release venlafaxine may require twice or thrice-daily dosing due to its shorter elimination half-life, as noted by the American Academy of Child and Adolescent Psychiatry 2, 3

Safety Considerations

• Blood pressure monitoring is important, as venlafaxine can cause modest increases in blood pressure, particularly at higher doses, according to Praxis Medical Insights 4
• Abrupt discontinuation should be avoided; tapering over 10-14 days is recommended to prevent withdrawal symptoms, as advised by Praxis Medical Insights 4
• Monitor for blood pressure changes, particularly when exceeding 150 mg/day, as recommended by Praxis Medical Insights 4
