Sino Nasal Spray is a steroid. It relieves the symptoms of allergic rhinitis such as runny nose, sneezing and sinus discomfort. It works by blocking the production of certain chemical messengers that cause inlammation (swelling) and allergies, thus relieving the discomfort and irritation in your nose. You should always use Sino Nasal Spray as advised by your doctor. To get the full benefit of the medicine you should use it regularly. Normally, you should blow your nose gently before using it, keep one nostril closed while applying the medicine into the other, and then sniff hard to make sure it reaches deep into the nose. Then repeat for the other nostril. Nasal irritation is a very common side effect of this medicine. It may also cause nosebleed and headaches in some patients. Talk to your doctor if you are worried about side effects or they do not go away. Using corticosteroids like this medicine makes you more susceptible to viral infections, so you should stay away from people who have these infections. In general, you should try to avoid situations which make your symptoms worse (things like pollen and dust mites) and it’s best not to smoke. Before using this medicine, you should let your doctor know if you are pregnant or breastfeeding. It is important to discuss the risks and benefits with your doctor. If you use this medicine for a long time, your doctor may want to carry out certain medical tests to check your progress.
