G Pancuronium Pancuronium Bromide Azathioprine
ModerateAzathioprine can lower the effect of pancuronium, so the muscle relaxation may be weaker than expected. The same drop in effect is seen with neostigmine, edrophonium, high-dose corticosteroids, KCl, calcium chloride, NaCl, heparin (a short-lived decrease), theophylline, pyridostigmine, neurolept analgesia and propanidid.
These medicines are often taken together with some care. Your doctor may change a dose, space them apart or check on you more often. Make sure your doctor and pharmacist know you take both.
