What if I am taking other drugs?

  • salbutamol, amphetamines, ephedrine, epinephrine, norepinephrine, phenylephrine, phenylpropanolamine, terbutaline, theophylline, caffeine – these drugs may increase the risk of side effects from pseudoephedrine
  • herbs including ephedra, ma huang, yohimbe – may increase risks of side effects from pseudoephedrine
