Prescription Medications

What Medications Disqualify a CMV Driver?

A driver cannot take a controlled substance or prescription medication without a prescription from a licensed practitioner.

If a driver uses a drug identified in 21 CFR 1308.11 (391) or any other substance such as amphetamine, a narcotic, or any other habit-forming drug, The driver is medically unqualified.

There is an exception: the prescribing doctor can write that the driver is safe to be a commercial driver while taking the medication. In this case, the Medical Examiner may, but does not have to certify the driver.

Any anti-seizure medication used for the prevention of seizures is disqualifying.
The Medical Examiner has 2 ways to determine if any medication a driver uses will adversely affect the safe operation of a CMV:

  • 1 Review each medication - prescription, non-prescription, and supplement
  • 2 Request a letter from the prescribing doctor
