What prescription drugs can interfere with the Five-Screen test and how is this dealt with?
April 11, 2010 in Employee Drug Testing Information
Certain over the counter medications can interfere with accurate results. These include ibuprofen and ephedrine-based products. Most drug testing companies will ask the applicant in advance what medications they have recently taken. The applicant should list these carefully. If the medication has compromised the result of the drug test the sample is automatically retested using a methodology that will identify the drug type. The applicant can present a doctor’s prescription for the medication that can be reviewed by the medical officer. Some medications will preliminarily test non-negative, but the confirmatory tests will rule out any non-illegal substances
Employers cannot discriminate in their hiring practices based on an applicant’s use of prescription medication for legitimate medical purposes. Such discrimination could be a violation of the Americans with Disabilities Act. Click on the link for:
