Influenza (flu) is a contagious viral infection that affects the respiratory system and can cause symptoms such as high fever, chills, body aches, fatigue, cough, sore throat, and nasal congestion. Symptoms often appear suddenly and may be more severe than those of a common cold.

This category includes a range of over-the-counter (OTC) products designed to help manage flu symptoms and improve comfort during recovery. These may include fever and pain relief medicines, cough syrups, throat lozenges, hydration support products, and multi-symptom flu formulations.
