Can Benadryl effect an Etg test?

Benadryl (diphenhydramine) is an antihistamine and does not contain alcohol, so it should not directly affect an ETG (ethyl glucuronide) test, which is designed to detect alcohol consumption. However, some products containing alcohol may be used in conjunction with Benadryl, potentially leading to a positive ETG result. It's important to check the specific formulations of any medications to ensure they do not contain alcohol. Always consult with a healthcare professional for personalized advice regarding medications and testing.
