Muscle fatigue

In myasthenia gravis, the muscles will improve immediately following the Tensilon. The maximum benefit only lasts several minutes.

In myasthenic crisis (worsening of the disease that requires anticholinesterase therapy), there is a brief improvement in the muscle strength.

In cholinergic crisis (overdose of anticholinesterase), Tensilon will exaggerate the muscle weakness.

Additional conditions under which the test may be performed include Lambert-Eaton syndrome.
