How many days does Ziv-aflibercept have an effect?

Aflibercept (Ziv-aflibercept)Treatment of colorectal cancer combined with FOLFIRI regimen, give aflibercept injection before giving any component of the FLOLFIRI regimen, every two weeks 4mg/kg (calculated based on actual body weight), intravenous injection time 1 When each patient receives aflibercept treatment, the dosage and course of treatment are different, which are mainly determined by the patient's disease stage, drug tolerance, and personal constitution. I believe that patients who receive aflibercept treatment according to the correct usage method will quickly achieve good results. When receiving drug treatment, patients are not allowed to increase or decrease the dosage without authorization to avoid other adverse reactions that may affect their condition.
