I have suffered a miscarriage and was prescribed

Customer Question

Hi, I have suffered a miscarriage and was prescribed promethazine for nausea and sleeping problems and 800mg aspirin alternating with 800mg ibuprofen every 4 h for pain. Could this combination increase my blood alcohol level or rate of alcohol metabolism? I have also not been eating most of the day, and my BAC was way above from what an online calculator indicated.

Thank you for your question. Unfortunately, formulas used to calculate estimated blood alcohol (such as the online calculator you used) are notoriously inaccurate. There are so many variables including the rate at which alcohol is consumed, food intake before, during or after drinking (which can slow influence the rate of absorption), degree of hydration to name a few.

Expert:  Family Physician replied 2 years ago.

Medications can impact the rate of alcohol metabolism, as can medical conditions such as liver disease.

There are also significant genetic variations in the metabolism (rate) between different individuals. Here is a scientific paper that goes into lots of details about the genetics of alcohol metabolism
