Renal Impairment:
No dose adjustment is necessary for patients with creatinine clearance above 60 mL/min. Dosage adjustments for adult patients with creatinine clearance ≤ 60 mL/min are as indicated below. Note that the dosage adjustments are based primarily on population pharmacokinetic modeling data.
Clinical safety and efficacy studies at these doses have not been performed.
Treatment of Influenza:
In adult patients with a creatinine clearance of > 30-60 mL/min, it is recommended that the dose be reduced to 30 mg of TAMIFLU twice daily for 5 days.

There is no evidence for efficacy of TAMIFLU in any illness caused by agents other than influenza viruses Types A and B. Data on treatment of influenza B are limited. Efficacy of TAMIFLU in patients who begin treatment after 48 hours of symptoms has not been established.
Efficacy of TAMIFLU in the treatment of subjects with chronic cardiac disease and/or respiratory disease has not been established. No difference in the incidence of complications was observed between the treatment and placebo groups in this population.
No information is available regarding treatment of influenza in patients with any medical condition sufficiently severe or unstable to be considered at imminent risk of requiring hospitalization. Safety and efficacy of repeated treatment or prevention courses have not been studied.
Efficacy of TAMIFLU for treatment or prevention of influenza in immunocompromised patients has not been established. 142 g of sorbitol. 6 g of sorbitol, which is unsuitable for subjects with hereditary fructose intolerance. Hepatic/Biliary/Pancreatic There have been post-marketing reports of elevated liver enzymes and hepatotoxicity including fulminant hepatitis/hepatic failure, in some cases with fatal outcome, where a causal relationship with PrTAMIFLU® (oseltamivir phosphate) Page 14 of 46 oseltamivir could not be excluded, especially in patients with pre-existing liver disease.
2 Recommended Dose and Dosage Adjustment, Dosage Adjustment, Hepatic Impairment). Neuropsychiatric There have been post-marketing reports of delirium and self-injury, in some cases resulting in fatal outcomes, in patients with influenza who were receiving TAMIFLU.
Because these events were reported voluntarily during clinical practice, estimate of frequency cannot be made but they appear to be uncommon based on TAMIFLU usage data. These events were reported primarily among pediatric patients.
The contribution of TAMIFLU to these events has not been established. Patients with influenza should be closely monitored for signs of abnormal behaviour. 5 Post-Market Adverse Drug Reactions, Neurologic, and Psychiatric). Influenza can be associated with a variety of neurologic and behavioural symptoms, which can include events such as hallucinations, delirium, and abnormal behaviour, in some cases resulting in fatal outcomes.
These events may occur in the setting of encephalitis or encephalopathy, but can occur without obvious severe disease.
