Summary Background Interferon‐free regimens are associated with high sustained virological response; however, associated adverse effects have yet to be fully reported. Aim To evaluate the adverse effects associated with the different direct‐acting antiviral drug ( DAA ) regimens in Egyptian patients. Methods This multicenter retrospective study included all adverse effects during and after treatment with DAA regimens of 149 816 chronic hepatitis C treated Egyptian patients. Patients received sofosbuvir ( SOF )/ribavirin ( RBV ) (n = 21 835), SOF /simeprevir (n = 24 215) SOF /daclatasvir ( DCV ) (n = 58 477), SOF / DCV / RBV (n = 45 188) and paritaprevir/ombitasvir/ritonavir/ RBV (n = 101). The duration of treatment varied between 12 and 24 weeks. All changes in the treatment regimens, discontinuation, mortality, and serious side effects were reported. Results Adverse effects developed in 2475 (1.7%) (mean age [54 ± 9], male gender [53%]) patients. Serious side effects developed in 68% of these patients, and SOF / RBV was the most common causing regimen (73%, P < 0.001). Anaemia and hyperbilirubinemia were the most common side effects (731/149816, 0.5% and 463/149816, 0.3%, respectively) and SOF/RBV (588/21835, 3% and 353/21835, 1.6%, respectively) showed the highest incidence in the treated patients. Hepatocellular carcinoma and mortality were reported in 0.02% and 0.06% of all treated patients, respectively. Patients with liver cirrhosis showed higher incidence of serious side effects (Log rank P = 0.045) and mortality (Log rank P = 0.025) than patients without liver cirrhosis. Male gender ( P = 0.012), lower haemoglobin ( P < 0.001), platelets ( P < 0.001) and albumin ( P = 0.001), higher bilirubin ( P = 0.002) and cirrhosis ( P < 0.001) were factors associated with serious side effects development. Conclusion Adverse effects associated with DAA s are few, anaemia being the most common. SOF / RBV regimen showed the highest rate of side effects while SOF / DCV showed the least.
