Today cocaine use is very frequently associated with adolescents with maladaptive personality traits and impulse control disorder. It requires a multidisciplinary approach and individualized treatments to improve the clinic and achieve the abandonment of consumption.

1. To assess the efficacy of monthly injectable paliperidone palmitate treatment in controlling impulsivity. 2. Determine the consumption of toxins after treatment.

Sample: Adolescents, 14-17 years old, with a diagnosis of Personality Limit T and cocaine consumption who start treatment with Paliperidone Palmitate LD IM (50-100mg / month) in monotherapy, with Diazepam 5mg if significant anxiety. Retrospective data collection. Plutchik impulsivity scale (IE) before starting treatment and at 3 months. Statistical analysis SPSS 20.0

Twelve adolescents who met the inclusion criteria were included and 12 adolescents, 83% male, 16% female, completed the questionnaires. After its application and correction through non-parametric tests (N <30), scores in the EI questionnaire of a mean of 37.42 points in the pretest were observed, corresponding to a severe level of impulsivity; and a mean of 26.28 points in the post-test, compatible with a mild-moderate degree of impulsive symptoms. A decrease in the consumption of toxins was observed in 65% of the cases.

In our experience, the management of toxic consumption in adolescent population with severe impulsivity symptoms has great limitations due to the scarce resources available. The Palpitate of Paliperidone long-term treatment has been useful in the approach of serious registered cases, being associated with symptomatic improvement and decrease in consumption.
