Can you drink alcohol with Venlafaxine (Effexor)?
Here is what the FDA-approved label for Venlafaxine (Effexor) actually says about alcohol — transcribed, not a secondhand guess.
Venlafaxine and alcohol, from the label
The label addresses alcohol directly. Under Information for Patients it states that although venlafaxine has not been shown to increase the mental and motor impairment caused by alcohol, patients should be advised to avoid alcohol while taking it; the Medication Guide likewise says do not drink alcohol while using venlafaxine. This is a precautionary avoid instruction, not a disulfiram-like reaction. Separately, a pharmacokinetic study cited under Drug Interactions found a single dose of ethanol had no effect on venlafaxine levels and venlafaxine did not exaggerate alcohol's psychomotor effects.
Frequently asked questions
Can you drink alcohol while taking Venlafaxine?
The FDA label advises against it. Venlafaxine and alcohol interact (summarized above), and the label directs avoiding or minimizing alcohol while taking it. Confirm with your prescriber or pharmacist for your situation.
How long after Venlafaxine can you drink alcohol?
There is no single number that fits every drug, and the safe gap depends on why the two interact — a drug that adds to alcohol's sedation is a concern while it is still in your system, while a disulfiram-type reaction (like metronidazole's) is avoided during treatment and for a labeled period after the last dose. Follow the specific guidance above and ask the prescriber who wrote the prescription; do not guess a window.
What happens if you drink on Venlafaxine?
The specific effect is described above, from the label. In most cases it means additive drowsiness and impaired coordination, or added strain on an organ the drug already affects — worse with more alcohol and in older adults. If you feel unwell after mixing the two, stop drinking and seek advice; call 911 for trouble breathing, fainting, or a rapid irregular heartbeat.
