Steroid sprays are medications that contain corticosteroids, which are anti-inflammatory substances. They are commonly used to treat conditions like allergic rhinitis and asthma by reducing inflammation in the nasal passages or airways. These sprays help relieve symptoms such as congestion, sneezing, and difficulty breathing. When using steroid sprays, it's important to follow the prescribed dosage to minimize potential side effects. Regular use can lead to improved control of symptoms, making daily activities more comfortable. Always consult a healthcare professional before starting or stopping any medication, including steroid sprays.
