Methods: a descriptive longitudinal study conducted at the Day Hospital of the Hospital Central del Instituto de Previsión Social of Paraguay, between April and May 2021. Those patients who underwent at least three chemotherapy sessions during the period studied were recruited and followed up. Sociodemographic and clinical data were recorded, as well as those relative to their cancer diagnosis, chemotherapy treatment, and adverse drug reactions (ADRs). Data were collected through interviews and medical records. Descriptive analysis. Results: the average age of patients was 50 years; 73% were female. The most prevalent type of tumour was breast cancer (42.6%), followed by colorectal cancer (19.1%). With 551 ADRs detected, the most prevalent events recorded were gastrointestinal (34.1%), dermatological (22.7%) and neurological (16.3%). Paclitaxel was the drug most prescribed; and 100% of patients presented ADRs. Conclusions: all patients experienced ADRs secondary to treatment with intravenous chemotherapy, and the most common were gastrointestinal and dermatological events.
