Antiflu, commonly known by its brand name Oseltamivir, is an antiviral medication used to treat and prevent influenza (the flu). It is most effective when administered within 48 hours of the onset of flu symptoms, which may include fever, cough, sore throat, and body aches. Oseltamivir works by inhibiting the neuraminidase enzyme, which is essential for the replication and spread of the influenza virus in the body.
Dosage Guidelines: For adults and adolescents aged 13 years and older, the recommended dosage of Antiflu 75 mg for treating influenza taken twice daily for five days. For pediatric patients, dosing varies based on weight. For example, children weighing less than 15 kg should receive 30 mg twice daily, while those over 40 kg should take 75 mg twice daily. For prophylaxis after exposure to the virus, adults should take 75 mg once daily for at least 10 days.
Precautions: While oseltamivir is generally well-tolerated, some patients may experience side effects such as nausea, vomiting, headache, or diarrhea. It is crucial to complete the full course of treatment even if symptoms improve early to ensure complete viral clearance. Patients with renal impairment may require dosage adjustments based on their creatinine clearance levels. Additionally, oseltamivir should be used cautiously in individuals with a history of severe allergies or hypersensitivity reactions.
Pregnant or breastfeeding women should consult healthcare providers before using oseltamivir to weigh potential risks and benefits. Overall, oseltamivir remains a vital tool in managing influenza outbreaks and reducing the severity of symptoms when administered promptly.
