What Is Tegretol?
Carbamazepine (brand name Tegretol) is a anticonvulsant mood stabilizer (Mood Stabilizer) prescribed for bipolar disorder, ptsd, aggression, and other psychiatric conditions. Oldest anticonvulsant mood stabilizer. Autoinduces its own metabolism (blood levels DROP over first month). Requires blood level monitoring. Potent CYP3A4 inducer — reduces levels of many other medications. HLA-B*1502 genetic test recommended before starting (risk of SJS in certain populations).
At Psychiatry Telemed, carbamazepine is prescribed and monitored by board-certified psychiatrists who understand the nuances of Mood Stabilizer pharmacology — selecting the right dose, managing side effects, monitoring drug interactions, and optimizing your treatment through consistent monthly medication management appointments.

How Tegretol Works
