What Is Flunisolide Nasal Solution?

Flunisolide nasal solution (Nasarel™, Nasalide®) is a prescription nasal spray licensed to treat sneezing, runny or stuffy nose, and nasal itching due to allergies (known medically as allergic rhinitis). Flunisolide nasal solution can be used to treat allergies that occur all year long (known as perennial allergies) as well as seasonal allergies, and can be used in children as young as six years old.

Who Makes Flunisolide Nasal Solution?

How Does Flunisolide Nasal Solution Work?

Allergies occur when a person's immune system reacts to normally harmless substances that do not bother most people. This immune system reaction is known as inflammation and involves several different types of cells and several different chemicals in the body.
Flunisolide nasal solution is a corticosteroid, or simply "steroid" for short. Steroids can have many different effects in the body, including anti-inflammatory effects. Steroids decrease inflammation by limiting the body's ability to produce an immune system reaction. They can be effective for treating conditions such as allergies. However, long-term use can cause bothersome and sometimes serious side effects, and this limits the usefulness of many steroids. Because flunisolide nasal solution is a nasal spray, its effects are generally limited to the nose. This helps prevent many of the long-term side effects of steroids.
