Neostigmine Methylsulfate (neostigmine methylsulfate (neostigmine methylsulfate injection) injection) Injection, USP does not antagonize, and may in fact prolong, the Phase 1 block of depolarizing muscle relaxants such as succinylcholine or decamethonium. Certain antibiotics, especially neomycin, streptomycin and kanamycin, have a mild but definite non-depolarizing blocking action which may accentuate neuromuscular block.These antibiotics should be used in the myasthenic patient only where definitely indicated, and then careful adjustment should be made of the anticholinesterase dosage. Local and some general anesthetics, antiarrhythmic agents and other drugs that interfere with neuromuscular transmission should be used cautiously, if at all, in patients with myasthenia gravis;the dose of Neostigmine Methylsulfate (neostigmine methylsulfate (neostigmine methylsulfate injection) injection) may have to be increased accordingly.
