About this medicine
What it is used for
INDICATIONS AND USAGE Pyridostigmine Bromide Tablets USP are useful in the treatment of myasthenia gravis.
How it is taken
DOSAGE AND ADMINISTRATION Each Pyridostigmine Bromide Tablet contains 60 mg pyridostigmine bromide. Dosage The size and frequency of the dosage must be adjusted to the needs of the individual patient. The average dose is ten 60 mg tablets daily, spaced to provide maximum relief when maximum strength is needed. In severe cases as many as twenty-five tablets a day may be required, while in mild cases one to six tablets a day may suffice. NOTE: For information on a diagnostic test for myasthenia gravis, and for the evaluation and stabilization of therapy, please see product literature on Tensilon (edrophonium chloride).

Myasthenic crisis due to an increase in the severity of the disease is also accompanied by extreme muscle weakness, and thus may be difficult to distinguish from cholinergic crisis on a symptomatic basis. Such differentiation is extremely important, since increases in doses of pyridostigmine bromide or other drugs of this class in the presence of cholinergic crisis or of a refractory or "insensitive" state could have grave consequences. Osserman and Genkins 1 indicate that the differential diagnosis of the two types of crisis may require the use of Tensilon TM (edrophonium chloride) as well as clinical judgment. The treatment of the two conditions obviously differs radically. Whereas the presence of myasthenic crisis suggests the need for more intensive anticholinesterase therapy, the diagnosis of cholinergic crisis, a
