The overall incidence of adverse reactions has been established from clinical studies in which 316 patients (132 patients suffering from NSCLC and 184 patients suffering from breast cancer) received the recommended protocol for vinorelbine soft-gelatin capsule (first three administrations at a dose of 60 mg/m
2/week followed by administrations at a dose of 80 mg/m
2/week).
The adverse reactions reported have been listed as follows by system organ class and incidence. The additional adverse reactions pooled from post-marketing experience and clinical trials have been added with unknown incidence consistent with the MedDRA classification.
The reactions are defined as follows using the NCI CTC severity grades. (See Table 3.)

The reactions are described using the WHO classification (grade 1=G1; grade 2=G2; grade 3=G3; grade 4=G4; grade 1-4=G1-4; grade 1-2=G1-2; grade 3-4=G3-4).
Adverse reactions reported with vinorelbine soft-gelatin capsule: Pre-marketing experience: The most commonly reported adverse effects are bone marrow depression with neutropenia, anaemia and thrombocytopenia together with gastrointestinal toxicity, with nausea, vomiting, diarrhoea, stomatitis and constipation. Fatigue and fever have also been reported commonly.
Post-marketing experience: Vinorelbine soft-gelatin capsule is used as monotherapy or in combination with other chemotherapeutic agents such as cisplatin or capecitabin.
The system organ classes most affected in post-marketing experience are the "Haematological and lymphatic system disorders", the "Gastrointestinal disorders" and the "general disorders and administration site abnormalities". This information is consistent with the pre-marketing experience.
