Common use

Effexor XR is indicated for the treatment of major depressive disorder (MDD), generalized anxiety disorder (GAD), social anxiety disorder (SAD), and panic disorder (PD) in adults. It is used both in acute-phase treatment and maintenance therapy to prevent relapse. Off-label uses may include management of certain neuropathic pain conditions and vasomotor symptoms associated with menopause, though these should only be pursued under strict medical supervision.

Dosage and direction

The recommended starting dose for most adults is 37.5 mg or 75 mg taken orally once daily, with or without food. Dosage may be adjusted at intervals of no less than 4–7 days, based on tolerability and therapeutic response. The maximum recommended dose is 225 mg per day. Capsules should be swallowed whole; they must not be divided, crushed, chewed, or dissolved. Dosage adjustments are necessary in patients with hepatic or renal impairment.

Precautions

  • Monitor for worsening depression, suicidality, or unusual changes in behavior, especially during initial treatment or dose adjustments.
  • Use with caution in patients with a history of seizures, hypertension, bipolar disorder, or angle-closure glaucoma.
  • May increase the risk of bleeding; use caution when co-administered with NSAIDs, aspirin, or anticoagulants.
  • Discontinuation should be gradual to avoid withdrawal symptoms; do not stop abruptly.
  • Not recommended during pregnancy unless potential benefits justify potential risks to the fetus.

Contraindications

  • Hypersensitivity to venlafaxine or any component of the formulation.
  • Concurrent use with monoamine oxidase inhibitors (MAOIs) or within 14 days of discontinuing MAOI therapy.
  • Use in patients with uncontrolled narrow-angle glaucoma.

Possible side effect

Common side effects may include nausea, headache, drowsiness, dry mouth, dizziness, insomnia, constipation, sweating, and nervousness. Less frequently, patients may experience increased blood pressure, palpitations, blurred vision, weight changes, or sexual dysfunction. Serious side effects, though rare, include serotonin syndrome, hyponatremia, abnormal bleeding, manic episodes, and seizures.

Drug interaction

  • MAOIs: Risk of serotonin syndrome; contraindicated.
  • Other serotonergic drugs (e.g., SSRIs, tramadol, triptans): Increased risk of serotonin syndrome.
  • NSAIDs/aspirin: May increase bleeding risk.
  • Drugs metabolized by CYP2D6 (e.g., certain antipsychotics, beta-blockers): Venlafaxine may inhibit their metabolism.
  • Warfarin: May potentiate anticoagulant effect; monitor INR.

Missed dose

If a dose is missed, take it as soon as remembered unless it is close to the time of the next dose. Do not double the dose to make up for a missed one. Maintaining a consistent dosing schedule is important to ensure stable therapeutic levels.

Overdose

Symptoms of overdose may include dizziness, sedation, tachycardia, changes in ECG intervals, seizures, or serotonin syndrome. Management is supportive and may include gastric lavage, activated charcoal, and symptomatic care. There is no specific antidote. Contact a poison control center or seek emergency medical attention immediately.

Storage

Store at room temperature (20–25°C or 68–77°F), in a tightly closed container, away from light, moisture, and heat. Keep out of reach of children and pets. Do not use after the expiration date printed on the packaging.
