Understanding EDDP and its Implications

EDDP on a drug screen refers to ethyl-diphenhydramine, a metabolite of diphenhydramine. Diphenhydramine, better known by brand names like Benadryl, is a common over-the-counter antihistamine used to treat allergies and insomnia. When your body processes diphenhydramine, it breaks it down into EDDP. This means a positive EDDP result doesn't necessarily indicate recent diphenhydramine use; it can linger in the system for some time.

Why is EDDP Detected?

Drug tests, especially those used in workplaces or legal contexts, often screen for metabolites like EDDP in addition to the parent drug (diphenhydramine itself). This is because metabolites can remain detectable in urine, blood, or hair for longer periods than the original drug. The presence of EDDP can help confirm diphenhydramine use, even if the diphenhydramine itself has been fully metabolized.

How Long Does EDDP Stay in Your System?

The detection window for EDDP, like many other drug metabolites, varies depending on several factors:

• Dosage: Higher doses will generally result in a longer detection period.
• Metabolism: Individual metabolic rates differ, affecting how quickly the body processes and eliminates EDDP.
• Frequency of Use: Regular diphenhydramine use will likely result in a longer detection window compared to a single dose.
• Testing Method: Different testing methods (urine, blood, hair) have varying detection windows. Urine tests generally have shorter detection windows than hair tests.

While precise timelines are difficult to provide, EDDP can be detectable in urine for several days after the last diphenhydramine dose, potentially even up to a week or more in some cases.

What Does a Positive EDDP Result Mean?

A positive EDDP result on a drug screen primarily indicates exposure to diphenhydramine. However, it's crucial to consider the context:

• Legitimate Use: A positive result might simply reflect the legitimate use of over-the-counter Benadryl for allergies or insomnia. Always be honest and provide any relevant information regarding your medication use to the testing entity.
• Misuse: While less common, diphenhydramine can be misused for recreational purposes, leading to a positive EDDP result. This could have legal or employment consequences.
• Contamination: Although unlikely, cross-contamination during testing could theoretically lead to a false positive. This is rare but possible, and proper laboratory protocols should minimize this risk.

Addressing a Positive EDDP Result

If you receive a positive EDDP result, it's essential to:

• Be Honest: Disclose any legitimate diphenhydramine use to the testing authority. Provide information about dosage, frequency, and the reason for use.
• Seek Clarification: If you believe the result is a false positive or need further explanation, consult with the testing facility or a healthcare professional. They can discuss the test's limitations and potential sources of error.
• Consider Retesting: If the situation necessitates it, and if allowed, you may be able to request a retest to confirm the initial findings.
