Patients receiving concomitant Slandom 8 and selective Serotonin reuptake inhibitors or Serotonin and Norepinephrine reuptake inhibitors should be carefully monitored; Only use Slandom 8 for prophylactic purposes, not for therapeutic purposes because the use of Ondansetron is to prevent vomiting and nausea and not to treat vomiting; Only use Slandom 8 for the first 24 to 48 hours after chemotherapy. Research shows that Slandom 8 does not increase effectiveness in cases of late onset nausea and vomiting; The clearance of Ondansetron is decreased and the half-life of Slandom 8 is increased in patients with hepatic dysfunction, therefore dose reduction is required in cases of severe hepatic impairment (Child-Pugh C); Hypersensitivity reactions to Slandom 8 have been reported in cases of hypersensitivity to other selective 5HT3 receptor antagonists; Do not use Slandom 8 for pregnant women and nursing mothers; Slandom 8 may cause adverse effects such as dizziness, fatigue...
