Symptomatic Control of Myasthenia Gravis
Symptomatic Control of Myasthenia Gravis One mL of the1:2000 solution (0.5 mg) IM or SC. Subsequent doses should be based on the individual patient’s response.
Prevention of Postoperative Distention and Urinary Retention
One mL of the 1:4000 solution (0.25 mg) IM or SC as soon as possible after operation; repeat every four to six hours for two or three days.
Treatment of Postoperative Distention
One mL of the 1:2000 solution (0.5 mg) IM or SC, as required.
Treatment of Urinary Retention
One mL of the 1:2000 solution (0.5 mg) IM or SC. If urination does not occur within an hour, the patient should be catheterized. After the patient has voided, or the bladder has been emptied, continue the 0.5 mg injections every three hours for at least five injections.
Reversal of Effects of Nondepolarizing Neuromuscular Blocking Agents
When neostigmine methylsulfate is administered IV, it is recommended that atropine sulfate (0.6 to 1.2 mg) also be given IV using separate syringes. Some authorities have recommended that the atropine be injected several minutes before the neostigmine methylsulfate rather than concomitantly. The usual dose is 0.5 to 2 mg neostigmine methylsulfate given by slow IV injection, repeated as required. Only in exceptional cases should the total dose of neostigmine methylsulfate exceed 5 mg. It is recommended that the patient be well ventilated and a patent airway maintained until complete recovery of normal respiration is assured. The optimum time for administration of the drug is during hyperventilation when the carbon dioxide level of the blood is low. It should never be administered in the presence of high concentrations of halothane or cyclopropane. In cardiac cases and severely ill patients, it is advisable to titrate the exact dose of neostigmine methylsulfate required, using a peripheral nerve stimulator device. In the presence of bradycardia, the pulse rate should be increased to about 80/min with atropine before administering neostigmine methylsulfate.
Parenteral drug products should beinspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.
