ABSTRACT
This study examined the potential effects of INH side effects and non-specific somatic complaints on medication adherence in 96 Latino adolescents participating in a controlled trial designed to increase isoniazid (INH) adherence. These participants (who received usual medical care) were interviewed monthly over 9 months. Participants were questioned regarding medication taking, the frequency of 15 INH-related side effects from the Physician's Desk Reference (PDR) [1], and 21 non-specific somatic complaints. Participants were aged 12-19 years, 53.1% were male, 66.7% were born in Mexico, 73% had no health insurance, and 52.5% were classified as bicultural. Approximately 70% of participants experienced at least one side effect during the trial. Side effects that occurred while taking INH were not significantly related to total number of pills taken; somatic complaints that occurred during 9 months of INH were significantly negatively related to cumulative adherence. Females reported significantly more somatic complaints at baseline than males.
