Interacting Drug
common examples
Interaction
Recommendation
alcohol, antidipressants, opioids
Possible additive CNS, respiratory
limit maximum dose of LAs,
CNS Depressants
benbenzodiazipines, muscle relaxants,
depression
especially with opioids
antipsychotics, antihistimines
increased affect of vasoconstrictor
Avoid vasoconstrictor with patients
can result in cardiac arrest
under the influence of cocaine
amitriptyline
may enhance systemic actions
Avoid levonordefrin, norepinephrine;
Tricyclic antidepressants
of vasoconstrictors
Use epinephrine cautiously -
imipramine
as low a dose as possible
alcohol, cannibis, benzodiazepines
increased depressant effect
Observe for increased response to
CNS depressants
barbiturates, opioids, etc
of either drug
CNS depression, decrease dose of
Benzodiazipine if necessary
medazolam (Versed),
Increased respiratory depression
titrate dosages and monitor
Benzodiazepines
triazolam (Halcion),
increased recovery time
for excessive sedation
alprazolam (Xanax)
increased risk of hypotension
slows the metabolism of opioids
alcohol, cannibis, benzodiazepines
CNS Depressants
increased CNS depression
monitor for excess sedation
barbiturates, opioids, etc
