What doses of venlafaxine do doctors use?
Venlafaxine dosing depends on whether you are taking the immediate-release (IR) or extended-release (ER) form and what condition you’re treating. The total daily dose is chosen to balance symptom control with tolerability.
How is venlafaxine started and increased?
Clinicians generally start at a lower dose and increase gradually if symptoms don’t improve and side effects are manageable. The specific starting dose and the pace of titration depend on whether the prescription is IR vs ER and on the target condition.
What’s the usual adult dose range?
Common adult prescribing patterns keep dosing within established ranges for IR and ER formulations, with ER typically given once daily and IR split across multiple doses per day. Your prescription should state the exact mg strength and how often to take it.
What dose is used for venlafaxine ER (extended-release)?
Venlafaxine ER is usually taken once daily. Doses are adjusted based on response and side effects, staying within the labeled dosing range for ER.
What dose is used for venlafaxine IR (immediate-release)?
Venlafaxine IR is typically taken in divided doses across the day. Dosing is adjusted based on symptom response and side effects, staying within the labeled IR dosing range.
What happens if you miss a dose?
If you miss a dose, take it when you remember unless it’s close to the next scheduled dose. Do not double up. The exact “what to do” can depend on whether your dose is IR (multiple daily doses) or ER (once daily).
Can dose be adjusted for older adults or kidney/liver problems?
Yes. Venlafaxine dosing may need reduction in people with kidney impairment or liver impairment, and clinicians may use lower starting doses in older adults to reduce the risk of side effects.
When should you call a clinician urgently?
Seek urgent medical help for severe adverse effects such as fainting, chest pain, severe dizziness, confusion, or signs of serotonin toxicity (for example, agitation, fever, sweating, tremor, or diarrhea), especially if you recently changed the dose or added another serotonergic medication.
Important safety notes
Do not change your dose or stop venlafaxine abruptly without medical guidance. Stopping suddenly can cause withdrawal symptoms; dose changes should be planned with a clinician.

If you tell me the exact formulation (ER vs IR), your age, and what condition you’re treating (for example, depression, anxiety, panic disorder), I can narrow this to the most relevant typical dosing schedule and how it’s usually titrated.
