Hello,
Thanks for your query at DoctorSpring.com
I understand your concern. Mild alcohol consumption should not interfere with warfarin action. Thanks for providing his vital parameters which are in the normal limit. Is he having symptoms like confusion, difficulty in respiration, severe vomiting/fits/seizures/loss of consciousness or any other severe symptoms? If that is the case, he needs to be admitted to the emergency department to monitor his electrolytes and other parameters. Otherwise, he should be fine with adequate rehydration and good rest. Please avoid alcohol consumption /or keep to minimal in future if on warfarin as it may alter warfarin action and may cause problems.
Hope it helps
Regards
