Will you pass a drug test for robitussin or Sudafed?

Robitussin and Sudafed are generally not included in standard drug tests, which typically screen for illegal substances such as marijuana, cocaine, and opioids. However, certain formulations of these medications can contain ingredients that may affect a drug test, particularly if they contain pseudoephedrine or dextromethorphan in high doses. It's always best to inform the testing administrator about any medications you are taking to avoid potential complications.
