Based on NIH | Can I drink alcohol after taking metoprolol, and how long should I wait before having a drink?

You can drink alcohol while taking metoprolol in some situations, but it’s safer to limit or avoid alcohol especially with extended‑release forms because alcohol can worsen side effects like dizziness, lightheadedness, and low blood pressure. ^{[1] [2]} If you use metoprolol extended‑release capsules (or tablets), you should not drink alcoholic beverages or take products containing alcohol, because alcohol can change how the medicine is released and increase side effects. ^{[3] [2]}

Quick guidance

• If you take metoprolol extended‑release (ER): Avoid alcohol completely while on the ER capsules; products containing alcohol are also not recommended. ^{[3] [2]}
• If you take immediate‑release (IR) metoprolol: Light to moderate drinking may be possible for some people, but it can still increase drowsiness, dizziness, and the risk of low blood pressure; use caution, hydrate, and avoid driving. ^[2]
• There is no universally “safe” wait time because effects can vary, but a cautious approach is to allow several hours after your dose, ensure you feel steady, eat food, and limit alcohol to a small amount if you choose to drink. ^[4]
• Heavy drinking should be avoided with any form of metoprolol due to greater risks of low blood pressure, fainting, and unpredictable alcohol levels. ^[5]

Why alcohol and metoprolol can be a risky mix

• Alcohol and metoprolol both slow parts of the nervous system and can lower blood pressure, so taken together they can cause more pronounced dizziness, lightheadedness, fainting, and drowsiness. ^[2]
• With metoprolol extended‑release capsules, alcohol can interfere with the controlled release, leading to higher peaks of the drug and more side effects; this is why alcohol is specifically advised against. ^{[3] [1]}
• Studies in healthy volunteers suggest that alcohol does not cancel the blood pressure–lowering effect of metoprolol, but combining them can still change how you feel and may worsen blood pressure control in routine life. ^[4]
• Longer‑term metoprolol use may change alcohol blood levels over time (faster rise and slower fall), which is another reason to avoid simultaneous high alcohol intake. ^[5]

How long to wait before drinking

• Extended‑release metoprolol: Because alcohol can alter ER release and raise side effects, the recommendation is to avoid alcohol altogether while taking ER capsules or tablets. ^{[3] [2]}
• Immediate‑release metoprolol: There isn’t an official fixed “wait X hours” rule, but a practical, safer approach is:
  • Take your dose with food, wait at least several hours, and make sure you feel stable (no dizziness). ^[4]
  • If you choose to drink, limit to a small amount (for example, 1 standard drink), sip slowly with food, and reassess how you feel before considering more. ^[4]
  • Avoid drinking near activities that require alertness (driving, climbing, operating machinery), since metoprolol can cause drowsiness on its own. ^[2]

Special situations to be extra cautious

• If you’ve recently started metoprolol or had a dose increase, you may feel stronger side effects; avoid alcohol until you know how you respond. ^[2]
• If you have a history of low blood pressure, dizziness, fainting, or are taking other medicines that lower blood pressure (including some erectile dysfunction drugs), use extra caution or avoid alcohol. ^[2]
• If you are on other medications that contain alcohol (certain cough syrups, elixirs, tinctures), check labels and ask a pharmacist. ^[3]

Practical tips if you choose to drink on IR metoprolol

• Eat a meal before and during drinking to reduce blood pressure dips and dizziness. ^[4]
• Start with half to one standard drink and wait to see how you feel before having more. ^[4]
• Stand up slowly to prevent lightheadedness, hydrate with water, and avoid hot environments (saunas, hot tubs) that can further drop blood pressure. ^[2]
• Stop drinking and sit or lie down if you feel faint, very dizzy, or unusually sleepy, and seek medical help if symptoms are severe. ^[2]

Summary

• Metoprolol ER: Do not drink alcohol or use alcohol‑containing products. ^{[3] [2]}
• Metoprolol IR: Some people may tolerate small amounts, but alcohol can increase side effects; wait several hours after dosing, ensure you feel well, eat, and keep intake low. ^[4]
• Heavy or rapid drinking should be avoided with any metoprolol due to safety concerns and possible changes in alcohol levels. ^[5]

If you’re unsure which formulation you take or how alcohol might affect your specific health conditions and other medications, it’s best to check with your clinician or pharmacist. ^[2]
