  • Phenytoin, barbiturate, carbamazepin, isoniazid may increase the hepatotoxicity of Acetaminophen.
  • Concomitant use of phenylephrine with other sympathomimetic amines can increase the risk of cardiovascular side effects.
  • Phenylephrine may reduce the efficacy of beta-blocking drugs and antihypertensive drugs (including debrisoquine, guanethidine, reserpine, methyldopa). The risk of hypertension and other cardiovascular side effects may be increased.
  • Tricyclic antidepressants (e.g. amitriptyline, imipramine): May increase the risk of cardiovascular side effects with phenylephrine.
  • Concomitant use of phenylephrine with ergot alkaloids (ergotamine and methylsergide): Increase the risk of ergotism.
  • Concomitant use of phenylephrine with digoxin: Increase the risk of irregular heartbeat or heart attack.
  • Concomitant use of phenylephrine with atropine will block the reflex bradycardia that phenylephrine causes.
  • Ethanol or hypnotics may increase the CNS inhibition effect of chlorpheniramine
  • Chlorpheniramine inhibits phenytoin metabolism and can lead to phenytoin toxicity.
  • Concomitant use of dextromethorphan and CNS inhibitors may increase the CNS inhibition of these drugs.
  • Quinidine inhibits cytochrome P450 2D6 and markedly increases the plasma levels of dextromethorphan which causes increased side effects of dextromethorphan.
