  • Pediatric patients: The safety and efficacy of Oseltamivir for prophylaxis of influenza in pediatric patients younger than 13 years of age have not been established.

Recommended oral dose for the treatment of influenza:

  • For prophylaxis of influenza in adults and adolescents 13 years and older following close contact with an infected individual: 75 mg once daily for at least 7 days. Therapy should begin within 2 days of exposure.

Side Effects

The most frequently reported adverse events are nausea and vomiting. These events generally of mild to moderate degree and usually are occurred on the first 2 days of administration. Additional adverse events occurring in <1% of patients receiving Oseltamivir for treatment include unstable angina, anemia, pseudomembranous colitis, humerus fracture, pneumonia, pyrexia, and peritonsillar abscess.


Oseltamivir is a prodrug of oseltamivir carboxylate. Oseltamivir carboxylate inhibits neuraminidase (sialidase), a viral surface enzyme which is responsible for the replication and infectivity of influenza virus A and B, thereby preventing the release of viruses from infected cells.

Antiflu Precaution

There is no evidence for efficacy of Oseltamivir Phosphate in any illness caused by agents other than influenza viruses Types A and B. Efficacy of Oseltamivir Phosphate in patients who begin treatment after 40 hours of symptoms has not been established.


Information derived from pharmacology and pharmacokinetic studies of Oseltamivir suggests that clinically significant drug interactions are unlikely. Co-administration with amoxicillin does not alter plasma levels of either compound.

Pregnancy Lactation use

Pregnancy Category C: There are insufficient human data upon which to base an evaluation of risk of Oseltamivir Phosphate to the pregnant woman or developing fetus.

Nursing Mothers: It is not known whether oseltamivir or oseltamivir carboxylate is excreted in human milk. Oseltamivir Phosphate should, therefore, be used only if the potential benefit for the lactating mother justifies the potential risk to the breast-fed infant.


Oseltamivir is contraindicated in patients with known hypersensitivity to any of the components of the product.

Special Warning

Hepatic Impairment: The safety and pharmacokinetics in patients with hepatic impairment have not been evaluated.

Renal Impairment: Dose adjustment is recommended for patients with a serum creatinine clearance <30 mL/min.

Geriatric Use: The safety of Oseltamivir Phosphate has been established in clinical studies.

Pediatric Use: The safety and efficacy of Oseltamivir Phosphate in pediatric patients younger than 1 year of age have not been studied. Oseltamivir Phosphate is not indicated for either treatment or prophylaxis of influenza in pediatric patients younger than 1 year of age.

Acute Overdose

At present there has been no experience of over dose. Single dose of up to 1000 mg of Oseltamivir have been associated with nausea and/or vomiting.
