Carbamazepine is one of the classical antiepileptic drugs, chemically related to the Tricyclic Antidepressants. There are different methods to detect Carbamazepine in plasma i.e. Therapeutic Drug monitoring (TDM). Various studies claim the usefulness of TDM of Carbamazepine but clear-cut guidelines for TDM are still lacking. This article is authors’ endeavour to summarize facts in different publications on TDM of Carbamazepine. Electronic databases MEDLINE/PubMed, Google Scholar, IMSEAR (Index Medicus for South-East Asia Region) and Scopemed were extensively searched with Mesh (Medical Subject Headings) terms “Carbamazepine” AND “drug monitoring” from earliest possible date (1966) to December, 2016. Articles in any language especially those published in recent years were given preference. For non-English articles, Google translation was used and only abstracts were included. Review is mostly centred on toxic effects, poorly adjusted therapies and poor seizure control. Individualization of drug dose with the help of plasma level detection is a must in case of Carbamazepine therapy. TDM helps better outcome by minimizing the risk of under or overdosing due to drug/food interaction or genetic polymorphism of enzymes and transporters involved in the metabolism of Carbamazepine.
