A Clinical Study of Toxication Caused by Carbamazepine Abuse in Adolescents

Abstract EN

Carbamazepine is known to produce the side effect of euphoria.

As such, it lends itself to being a drug of abuse, particularly in the adolescent population.

This retrospective study evaluated carbamazepine abuse, treatment course, and associated morbidity in Chinese adolescents.

The median dose of carbamazepine resulting in overdose was 2,000 mg (800–5,000).

Patients were largely from urban-rural fringe areas (76.47%, 52.94%) with school performance within the last 1/3 range and (52.94%) unsupervised by parents.

35.29% experienced an obvious sense of euphoria.

All patients had nervous system symptoms, 6 (35.29%) cases developed coma (GCS < 8), and 5 (29.41%) cases experienced convulsion.

Four cases were treated with hemodialysis.

The incidence rate in young patients with repeat carbamazepine use and without the supervision of parents was higher than that in first-time users (5/7 versus 4/10), but the difference was not significant.

The toxic dose of repeat users was 3428 ± 1035 mg, significantly higher than that of 1470 ± 646 mg in first-time users (P=0.001).

Carbamazepine can produce a sense of euphoria, which is more likely to lead to its abuse and overdose in adolescents.

To prevent carbamazepine abuse and overdose will be critical in educating at-risk adolescents and preventing associated morbidities in the future.
