Allegra Nasal Spray is a corticosteroid medicine containing Fluticasone Furoate 27.5mcg. It is primarily used to relieve symptoms of allergic rhinitis, such as a runny nose, sneezing, nasal congestion, and sinus discomfort. This Allegra Nasal Spray works by reducing inflammation (swelling) and allergic reactions in the nose. It does this by blocking the production of certain natural chemical messengers in the body that cause these symptoms.

You should always use Allegra Nasal Spray exactly as advised by your doctor. To get the full benefit, it's important to use it regularly. It may take a few days for the nasal spray to take full effect and provide noticeable relief. If your symptoms do not improve after a week of regular use, please talk to your doctor.

Common side effects of Allegra Nasal Spray may include nasal discomforts such as burning, itching, or irritation. Some individuals may also experience nosebleeds, nasal inflammation, or headaches. If you are concerned about any side effects or if they do not go away, consult your doctor. As this medicine may slightly lower your body's ability to fight off infections, try to avoid close contact with individuals who have chickenpox, measles, or tuberculosis. It is generally advisable to avoid situations that trigger your symptoms (like exposure to pollen and dust mites) and to avoid smoking.

Before starting to use Allegra Nasal Spray, inform your doctor if you are pregnant or breastfeeding to discuss the potential risks and benefits. If you need to use this medicine for a long period, your doctor may recommend certain medical tests to monitor your progress during treatment.
