In most cases, nasal steroid sprays are not an effective treatment for glue ear and are not recommended as a primary solution by UK clinical guidelines. While these sprays are highly effective for treating nasal allergies or persistent congestion, clinical evidence from the National Institute for Health and Care Excellence, or NICE, shows that they do not significantly speed up the clearance of fluid trapped behind the eardrum. Because glue ear is caused by fluid in the middle ear rather than inflammation in the nasal passages alone, the steroid medication rarely reaches the area necessary to resolve the condition.

The Evidence Against Nasal Steroids
Extensive clinical trials, including major studies published in the British Medical Journal, have compared nasal steroid sprays to placebos for children with glue ear.
When Steroids Might Be Used
While they do not treat the glue ear directly, a GP or specialist may still prescribe a nasal steroid spray if the child has co existing conditions.
- Allergic Rhinitis: If hay fever or dust allergies are causing significant swelling at the back of the nose where the Eustachian tube opens, treating the allergy may indirectly help the ear ventilate.
- Adenoid Inflammation: Steroids are sometimes used to reduce the size of inflamed adenoids that are physically blocking the ear tubes, though this is often a separate clinical goal from clearing the fluid itself.
- Persistent Congestion: Reducing overall nasal inflammation can make a child more comfortable, even if it does not directly restore their hearing thresholds.
Why the Spray Fails to Reach the Fluid
The fundamental problem with using sprays for glue ear is the physical location of the fluid.

Glue ear fluid is trapped in a sealed chamber behind the eardrum. A nasal spray is designed to coat the lining of the nose. Even when used with the correct technique, the amount of medication that reaches the opening of the Eustachian tube is very small. Furthermore, once the tube is already blocked by thick fluid, the spray cannot travel up the tube to thin the fluid or encourage it to drain.
Recommended Alternatives
Instead of relying on nasal steroids, UK clinicians often recommend other non surgical methods during the watchful waiting phase.
For older children, usually over age four, autoinflation devices like the Otovent balloon are often recommended. Unlike sprays, these devices use physical pressure to force the Eustachian tube open, which has a much stronger evidence base for clearing fluid and improving hearing during the three month observation window.
To Summarise
Nasal steroid sprays are generally not the answer for improving glue ear symptoms. Clinical guidelines advise against their use for this specific condition because they do not effectively clear middle ear fluid or improve hearing outcomes. While they remain useful for treating allergies, the most effective management for glue ear remains a period of watchful waiting to allow for natural resolution, or the use of mechanical aids like autoinflation balloons.
If your child has been prescribed a nasal spray, the next clinical step is to confirm if it is being used to treat a separate nasal allergy or if it was intended specifically for their ears, as a follow up hearing test remains the only way to track actual progress.
Will a steroid spray hurt my child?
When used correctly, nasal steroids are very safe. However, they can sometimes cause minor side effects like nasal dryness, stinging, or occasional nosebleeds
Can I buy these sprays over the counter for glue ear?
While some are available without a prescription, you should not use them to treat glue ear unless specifically advised by a doctor, as they are unlikely to help and can delay more appropriate monitoring.
What if the spray seems to be working?
Glue ear often resolves naturally. If hearing improves while using a spray, it is much more likely that the body cleared the fluid on its own or that the spray simply resolved a temporary nasal cold.
How long should I wait before stopping a spray that is not helping?
You should always complete the course prescribed by your doctor. However, if there is no change in hearing after several weeks, it is worth discussing the lack of progress at your next clinical review.
Are oral steroids different?
Yes. Oral steroids, such as syrups or tablets, are much stronger and have a slightly better short term effect on fluid, but because of their potential side effects, they are also not recommended for routine glue ear treatment in children.
Is saline spray better?
Saline sprays can help clear mucus from the nose, which might make a child feel better, but like steroid sprays, they do not have the power to drain fluid from behind the eardrum.
