Treatment and prevention of influenza A and B infections
This medicine is used to treat influenza A and B viral infections in infants over 2 weeks of age to adults. It should be started within 48 hours after the onset of initial symptoms for it to be effective. It is also used for the prevention of influenza infection in children over 1 year and adults, but only as an adjunct when vaccination is not feasible. This medication cannot replace vaccination, so remember that vaccination therapy should take precedence. This medication helps alleviate the symptoms of influenza infections and provides prevention.
1. Influenza A and influenza B virus infections: Treatment should be initiated on the first or second day after the onset of influenza symptoms. This medicine may be administered regardless of food intake, and tolerability may improve in some patients when taken with food. Adults and adolescents aged 13 years and older: Administer 75 mg of oseltamivir orally twice daily for 5 days. Adults and adolescents aged 13 years and older who have difficulty swallowing capsules should use this medicine as a powder for oral suspension. Patients with renal impairment: No dose adjustment is required for patients with a creatinine clearance of 60 mL/min or greater. For patients with a creatinine clearance of 30 ~ 60 mL/min, a reduced dose of 30 mg twice daily for 5 days is recommended. For patients with a creatinine clearance of 10 ~ 30 mL/min, a reduced dose of 30 mg once daily for 5 days is recommended. Patients receiving regular hemodialysis should receive a 30 mg dose of this medicine after each dialysis session to maintain plasma concentrations within the therapeutic range; the treatment duration should not exceed 5 days. If influenza symptoms develop during the 48 hours between dialysis sessions, this medicine may be administered before the start of dialysis. For peritoneal dialysis, a single 30 mg dose of this medicine after dialysis is recommended. The pharmacokinetics of oseltamivir have not been studied in patients with end-stage renal disease who are not receiving dialysis (e.g., creatinine clearance less than 10mL/min); therefore, no recommended dose is available for these patients. Patients with hepatic impairment: No dose adjustment is required for treatment in adult patients with mild to moderate hepatic impairment (Child-Pugh score ≤ 9). 2. Prevention of influenza A and influenza B virus infections Adults and adolescents aged 13 years and older: For individuals in close contact with an infected person, administer 75 mg of oseltamivir orally once daily for 10 days. Initiate administration within 2 days of contact with the infected person. The recommended dose for prevention during an influenza outbreak is 75 mg once daily. The safety and efficacy of this medicine have been demonstrated for up to 6 weeks. The preventive effect continues while taking this medicine. Patients with renal impairment: No dose adjustment is required for patients with a creatinine clearance of 60 mL/min or greater. For patients with a creatinine clearance of 30 ~ 60 mL/min, a reduced dose of 30 mg once daily is recommended. For patients with a creatinine clearance of 10 ~ 30 mL/min, a reduced dose of 30 mg every other day is recommended. Patients receiving regular hemodialysis should receive a 30 mg dose of this medicine after every 2 dialysis sessions to maintain plasma concentrations within the therapeutic range. The first dose may also be administered before the start of dialysis. For peritoneal dialysis, administration of 30 mg of this medicine once weekly after dialysis is recommended. The pharmacokinetics of oseltamivir have not been studied in patients with end-stage renal disease who are not receiving dialysis (e.g., creatinine clearance less than 10mL/min); therefore, no recommended dose is available for these patients. Patients with hepatic impairment: No dose adjustment is required for prevention in adult patients with mild to moderate hepatic impairment (Child-Pugh score ≤ 9).

This medication cannot replace influenza vaccination and must be used separately from it. It is effective only against influenza A and B viruses, and its safety and effectiveness against other infections have not been established. Particularly in children and adolescents, neuropsychiatric adverse reactions have been reported, and symptoms such as abnormal behavior or convulsions may occur, so guardians should closely monitor during use. Generally, the use of this medication in children over 10 years of age is not recommended unless under special circumstances. Do not take this medication if you are allergic to it or its components. Patients with renal failure or on dialysis require dosage adjustment, and it is not recommended for end-stage renal failure patients. Caution should be exercised in high-risk patients with asthma, chronic bronchitis, or immunocompromised status. Common side effects include nausea, vomiting, headache, and pain, most of which are transient and mild. Rarely, shock, anaphylaxis, liver dysfunction, skin rash, acute renal failure, or neuropsychiatric issues may occur, so unusual symptoms should be reported to healthcare providers immediately. Pregnant or breastfeeding women should use this medication only when its benefits outweigh the risks, and adequate data on its effects on fetuses or infants are not yet available. Safety and efficacy in children under 1 year have not been established. Elderly patients may have reduced physiological functions, so they should be monitored carefully during use, although dosage adjustment is not necessary. Overdose is generally not reported to cause serious side effects, but the prescribed dosage should be strictly followed. This medication has a low likelihood of drug interactions, but caution may be necessary when combined with certain medications. No special effects have been reported when driving vehicles or operating machinery, but the impairment caused by influenza itself should be noted. Keep this product out of reach of children and do not transfer it to other containers.
