What is a one-sentence summary of the following article?
Since Flonase is a corticosteroid and may decrease your body's ability to fight infections, you need to take extra precautions while using it. If you get sick, let your doctor know immediately. You should always give healthcare providers a complete list of medications you're taking. Remember to include fluticasone inhalation/spray on your list. Stay away from people who are sick and wash your hands often. Be especially careful to stay away from people who have chickenpox or measles. Tell your doctor right away if you find out that you have been around someone who has one of these viruses. In rare cases, prolonged use of corticosteroids decreases your body's ability to respond to physical stress. As such, it's very important that your doctors know you're using Flonase before you undergo any surgery (including dental surgery) or emergency treatment.
Report illness immediately. Avoid infectious germs and diseases. Report Flonase use before surgeries or emergency treatment.
