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.
