Dear Sir:

The blood alcohol test detects the amount of alcohol is a patient's blood at the time of testing. The blood alcohol test (BAC) is one of the most accurate methods to diagnose blood alcohol levels.

However, there are some medicines that can alter the blood alcohol test results. Some over the counter medications contain a certain content of alcohol, including cold and cough medications, mouthwashes, and certain prescription medications such as Dilantin, Theophylline, Furosemide, Lomotil, and CImetidine elixirs.

You need to ask your doctor to review your medications to see which ones might cause false positive elevated blood alcohol tests due to interactions with alcohol, or alcohol content within the medication itself. I hope this helps you. Good luck!
