Pentobarbital sodium injection is topic to manage with the Federal managed Substances Act less than DEA program II. Barbiturates could possibly be practice forming. Tolerance, psychological dependence, and Actual physical dependence may come about Particularly subsequent prolonged use of superior doses of barbiturates. everyday administration in excessive of 400 milligrams (mg) of pentobarbital or secobarbital for approximately ninety times is likely to produce some degree of physical dependence.

routine maintenance of an sufficient airway, with assisted respiration and oxygen administration as needed.
