Instructions from the labels

  • Duloxetine: swallow the capsule whole, with or without meals. If a dose is missed, take it when remembered unless the next one is nearly due; never take two at once.[1]
  • Venlafaxine XR: once a day with food at about the same time, swallowed whole with fluid, not divided, crushed or chewed.[2]
  • Stopping duloxetine can bring dizziness, headache, nausea, diarrhea, tingling, irritability, vomiting, insomnia, anxiety, heavy sweating and fatigue; the label recommends a gradual reduction.[1]
  • With venlafaxine, discontinuation symptoms became more frequent at higher doses and after longer treatment.[2]
  • Zepbound slows stomach emptying and may change how pills taken with it are absorbed.[3]

Do not wait for the next appointment

  • Agitation, confusion, fast heartbeat, sweating, fever, tremor, stiffness or muscle jerks, especially after a new medicine was added: contact your healthcare provider or go to the emergency room.[2]
  • Nausea, vomiting or diarrhea that does not go away: tell your healthcare provider right away.[3]
  • Severe stomach pain that will not go away, with or without vomiting: stop Zepbound and call your healthcare provider right away.[3]

  3. Should one of these doses stay the same while the other one changes?
  4. What should I do if vomiting makes me miss more than one SNRI dose?
  5. Which of you should I call first if new symptoms start?
