Having said that, concentrations with the drug required to produce this effect in humans are certainly not arrived at with sedative-hypnotic doses. Phenobarbital does not impair normal hepatic function but is demonstrated to induce liver microsomal enzymes, Hence expanding and/or altering the metabolism of barbiturates and other drugs. (See DRUG INTERACTIONS.)

In children and infants, phenobarbital at loading dose of fifteen to 20 mg/kg generates blood levels of about 20 µg/mL shortly immediately after administration. In status epilepticus, it truly is vital to realize therapeutic blood levels of phenobarbital as quickly as feasible. For the reason that a barbiturate-induced depression may well manifest along with a postictal depression when the seizures are controlled, it is vital, consequently, to make use of the minimal amount required, and to wait for the anticonvulsant effect to build before administering a second dose.
