Approximately 93.5 hours (4 days). It takes 5.5 x elimination half-lifes for a medicine to be cleared from ones system. The elimination half-life of Tegretol varies depending on whether it is initial dose or repeated dosing. Initial half-life values range from 25-65 hours, decreasing to 12-17 hours on repeated doses. Tegretol is metabolized in the liver. If you had been taking Tegretol for a while then the expected time for Tegretol to clear from your system would be approximately 93.5 hours (5.5 x 17 hours).

Tegretol (carbamazepine) is an anticonvulsant. It works by decreasing nerve impulses that cause seizures and pain.

Tegretol is used to treat certain types of seizures (partial, tonic-clonic, mixed). It is also used to treat nerve pain such as trigeminal neuralgia and glossopharyngeal neuralgia.
