Can you drink alcohol with Propranolol (Inderal)?
Here is what the FDA-approved label for Propranolol (Inderal) actually says about alcohol — transcribed, not a secondhand guess.
Propranolol and alcohol, from the label
The label's Drug Interactions section addresses alcohol directly: "Alcohol, when used concomitantly with propranolol, may increase plasma levels of propranolol." The concern the label names is pharmacokinetic — drinking can raise the amount of propranolol in the blood — not a disulfiram-type reaction and not additive CNS/respiratory depression. The label does not otherwise tell patients to avoid alcohol; it simply notes this interaction.
Frequently asked questions
Can you drink alcohol while taking Propranolol?
The label flags caution rather than an outright ban. Propranolol and alcohol can add up (summarized above), so if you drink, do so carefully and know your own tolerance — and ask a pharmacist if you take other medicines.
How long after Propranolol 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 Propranolol?
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.
