Short answer: Yes, you can drink alcohol after taking Plan B, but with caveats. What to consider

• Plan B (levonorgestrel) does not have a proven, direct interaction with alcohol. Drinking alcohol is unlikely to reduce Plan B’s effectiveness in a typical scenario.

• Avoid heavy or binge drinking right after taking Plan B. Excessive alcohol can cause nausea or vomiting, which might interfere with the pill’s absorption if vomiting occurs within a couple of hours after ingestion.

• If vomiting occurs within about two hours of taking Plan B, the pill may not be absorbed properly and its effectiveness could be reduced. In that case, a repeat dose may be needed, and you should contact a healthcare professional promptly.

• Alcohol can increase feelings of nausea or dizziness in some people taking Plan B, so moderating intake and ensuring you tolerate the medication well is advisable.

Practical tips

• If you choose to drink, do so in moderation and avoid taking Plan B with alcohol in the same immediate moment. Give the pill time to be absorbed.
• Monitor for side effects like nausea, vomiting, or abdominal cramps. If vomiting occurs within 2 hours of taking Plan B, seek medical guidance about whether a repeat dose is necessary.

• If you have any concerns about interactions with other medications, medical conditions, or pregnancy risks, consult a healthcare provider for personalized advice.

Bottom line: Moderate alcohol use after taking Plan B is generally considered safe and not known to undermine the pill’s efficacy, but avoid vomiting and be mindful of nausea or other side effects that could affect absorption. If vomiting occurs soon after ingestion, seek medical guidance.
