Common Use

Oseltamivir suppresses and decreases the spread of influenza A and B viruses. It blocks the activity of neuraminidase, the enzyme responsible for spreading the flu virus from infected cells to healthy ones. By blocking virus propagation, it stops the production of toxins that cause severe flu symptoms.

Oseltamivir reduces symptom duration by one and a half days if treatment starts within 48 hours of symptom onset. It can also be used preventatively for people exposed to the flu who have not yet developed symptoms.

Dosage and Direction

Take Oseltamivir orally as follows:

• Treatment dose: 75 mg twice daily for 5 days.
• Preventative dose (after exposure): 75 mg daily for 10 days.

Children's dosage should be adjusted based on weight.

Precautions

• Start treatment as soon as flu symptoms appear.
• Do not stop treatment early, even if symptoms improve.
• Consult your doctor before use if you have kidney disease, heart disease, lung disease, brain disorders, or other serious health conditions.
• Approved for children aged 1 year and older and postpartum women with flu.
• Pregnant women should consult a doctor, as flu risks may outweigh vaccine risks.

Contraindications

• Hypersensitivity to any components of Oseltamivir.
• Dose adjustment required for adults with severe kidney impairment.
