Background: An adverse drug event (ADE) is an injury resulting from medical intervention associated with a drug. This study assesses the incidence of ADEs among participants on second-line drugs for tuberculosis (TB) in Cameroon. Methods: This was a longitudinal observational study including 65 participants and carried out from January 2017 to December 2017. Markers of ADEs were obtained from creatinine, transaminase audiogram, and clinical data. Multivariate analysis was used to determine the association between predictors and ADEs. Results: Forty-eight (73.8%) of the 65 participants developed 72 ADEs. Fifty-four (75%), 11 (15.3%), and 7 (9.7%) of the 72 ADEs were classified as Grades 1, 2, and 3, respectively. Gastrointestinal disorders were most common (35 [46.6%]) followed by auditory injuries (16 [22.2%]), hepatotoxicity (11 [15.3%]), neurological disorders (6 [8.3%]), and kidney disorders (4 [5.6%]). The follow-up duration of this study was 11,250-person day (PDY). The incidence rate for ADEs was 4.3/1000 PDY and that for gastrointestinal disorders, auditory injuries, hepatotoxicity, neurological disorders, and kidney disorders was 3.1, 1.4, 1.0, 0.5, and 0.2 (/1000PDY), respectively. Kanamycin (65 [90.3%]), isoniazid (4 [5.6%]), and ethambutol (3 [4.2%]) were incriminated with ADEs. Most (29 [60.4%]) of the ADEs occurred during the first 2 months of drug initiation. There was an association between poor treatment outcome and ADEs (P = 0.04, odds ratio = 1.20, 95% confidence of interval = 0.21–6.80]. Conclusions: The incidence of ADEs is associated with several factors and most of them occurred during the intensive phase of treatment. Kanamycin was the most associated drug linked to ADEs requiring its replacement with a less toxic one.
