- -Paresthesia,
peripheral

Med
Interactions
Decrease
effectiveness of
oral
contraceptives
Aspirin
increases PCN
concentration
Increases
metformin
level.
Nephrotoxicity
if taken with
aminoglycoside
Erthythromycin
and
clarithromycin
can increase
PT/INR if on
Warfarin
Meds that
prolong QT or
bradycardia
Cipro->
metformin
Levo ->
warfarin
Potentiates
sulfonylureas,
phenytoin and
anticoagulants.
Decrease
effectiveness of
oral
contraceptives
Can potentiate
oral
anticoagulants
With contrast
agents can cause
renal toxicity.
With loop
diuretics can cause
ototoxicity
Precautions
Hypersensitivity
to
Cephalosporins
Hypersensitivity
to PCNs
Previous
arrhythmias
Require peak and
trough levels
