No, yellow mucus alone does not necessarily require antibiotics. Most of the time, yellow mucus is a sign that your body is fighting off a viral infection, such as the common cold. Antibiotics are not effective against viruses. However, if your symptoms persist for more than 10 days, worsen, or are accompanied by a high fever, it's important to see a healthcare provider as it may indicate a bacterial infection, where antibiotics might be necessary.
