What is Omnaris and How Does It Work?
Omnaris is the brand name for a nasal spray containing the active ingredient ciclesonide. It belongs to a class of drugs known as corticosteroids, which work by decreasing inflammation. A key feature of Omnaris is that ciclesonide is a prodrug. This means the medication is administered in an inactive form. Once sprayed into the nose, enzymes in the nasal passages convert ciclesonide into its active metabolite, des-ciclesonide.
This active form has a high affinity for glucocorticoid receptors, which are involved in the body's inflammatory response. By binding to these receptors, des-ciclesonide helps to reduce the release of inflammatory substances like histamines and cytokines. This action directly targets and reduces the swelling, irritation, and mucus production in the nasal passages that cause uncomfortable allergy symptoms. This on-site activation is designed to concentrate the drug's effect in the nose, and Omnaris has very low systemic absorption, meaning less than 1% of the dose becomes bioavailable in the rest of the body.
What Conditions Does Omnaris Treat?
Omnaris is a prescription medication specifically approved by the FDA for treating nasal symptoms associated with:
- Seasonal Allergic Rhinitis: For adults and children 6 years of age and older. This type of allergy, often called hay fever, occurs during specific seasons when allergens like pollen are high.
- Perennial Allergic Rhinitis: For adults and adolescents 12 years of age and older. This refers to year-round allergies triggered by indoor allergens like dust mites, pet dander, and mold.
The medication effectively reduces symptoms such as nasal congestion, runny nose, sneezing, and itching. The onset of effect can sometimes be seen within 24-48 hours, though it may take up to two weeks to feel the full benefit for seasonal allergies and up to five weeks for perennial allergies.
How to Use Omnaris Correctly
Proper administration is crucial for the effectiveness of Omnaris. Always follow the specific directions provided by your healthcare provider, including the prescribed amount and frequency.
- Preparation: Shake the bottle gently before each use. Before the first use, you must prime the pump by pressing it a specific number of times until a fine mist appears, as indicated in the instructions. If the spray has not been used for a certain number of days, it needs to be reprimed.
- Administration: Gently blow your nose to clear the nostrils. Tilt your head slightly forward and insert the tip into one nostril, aiming it toward the outside wall, away from the nasal septum (the wall between your nostrils).
- Actuation: Close the other nostril with a finger. As you begin to breathe in gently through your nose, press the pump firmly to release a spray. Repeat the spraying process as directed for each nostril.
- Cleaning: After use, wipe the applicator tip with a clean, dry tissue and replace the dust cap.
Potential Side Effects and Precautions
Like all medications, Omnaris can cause side effects. Many people use it without experiencing serious issues.
Common Side Effects:
- Headache
- Nosebleed (epistaxis)
- Sore throat (nasopharyngitis)
- Nasal irritation or discomfort
- Ear pain
Serious Side Effects: While rare, some side effects require immediate medical attention. These can include signs of a fungal infection in the nose or throat (white patches), vision changes like glaucoma or cataracts, or impaired wound healing. Patients should be monitored for these effects, especially with long-term use. Because corticosteroids can suppress the immune system, you should be careful to avoid exposure to infections like chickenpox or measles.
Individuals with recent nasal ulcers, surgery, or trauma should not use Omnaris until healing has occurred.

Conclusion
So, what does Omnaris do? It serves as a targeted, prescription-strength treatment for the nasal symptoms of allergic rhinitis. Its unique quality as a prodrug means it becomes active primarily in the nasal passages, where it reduces the inflammation that leads to congestion, sneezing, and a runny nose. While other options, including over-the-counter sprays like Flonase and Nasonex, are available, Omnaris offers a specific formulation that is scent-free and has low systemic bioavailability. A discussion with a healthcare provider is the best way to determine if Omnaris is the right choice for managing your allergy symptoms.
