Summary
In patients with myasthenia gravis, corticosteroids can transiently worsen muscle weakness, and this may be more pronounced when anticholinesterase therapy is given at the same time. The risk matters mainly for those with myasthenia gravis, and respiratory weakness is possible.
What this interaction means in plain words
Physostigmine and Triamcinolone can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
Corticosteroids may transiently worsen neuromuscular transmission in myasthenia gravis, opposing anticholinesterase benefit; the mechanism is not fully established.
What to do
In myasthenia gravis, start corticosteroids under close observation, ideally in hospital, and watch for worsening weakness and respiratory function. In patients without myasthenia, no special action is generally needed.
