Learn all about the flu
At first, a flu can seem like a cold. However, the flu can only be caused by 3 main viruses that result in a much more severe infection.1 Flu symptoms also appear quickly and will usually peak after 2 to 3 days; within about 8 days you should finally start to feel better.2 Symptoms of the flu include fever, a sore throat, a headache, muscle aches, fatigue, congestion and coughs.3
If you want fast relief from nasal congestion, then a medicated nasal spray like Otrivin Nasal Sprays can help clear your nose.
Speak to your doctor or healthcare professional if symptoms persist, or concern you.
