Flerixal, an antiviral medication used primarily for the treatment of influenza, typically lasts in the body for about 24 to 48 hours after administration. However, its effectiveness in alleviating symptoms may vary depending on the individual and the timing of the treatment. For optimal results, it is recommended to take it within the first 48 hours of flu symptoms. Always consult a healthcare professional for specific guidance regarding its use.
