Yes, the pseudoephedrine contained within Allegra D will show up on a drug test as methamphetamine.

However, if this is the case, then an additional and more comprensive test can be taken that will determine via the metabolites if the trace is actually methamphetamine or Allegra D.

Will Allegra D show up on a drug test?
  • The drug Allegra D contains the active components of fexofenadine and pseudoephedrine.
  • Fexofenadine reduces the levels of the chemical histamine in the body. High levels of histamine cause symptoms of itching, sneezing, watery eyes, and a runny nose.
  • Pseudoephedrine stops the effects of a blocked nose. It restricts the blood vessels in the nasal passage which decreases the amount of nasal congestion.
  • Allegra D is used to treat the effects of a common cold or cough. It is also used to alleviate the irritation caused by a blocked nose, watery eyes and skin rashes.
  • Always inform your doctor before taking a product such as Allegra D, as it can react badly with any other medications that you may be taking.
Before taking a drug test, take the packet of Allegra D to the test and inform the technician that you have been taking this medication.

As stated earlier, the Allegra D will appear on the test as methamphetamine, but a more accurate test can then be carried out to establish that you were not taking any illegal or abusive substances.
