Oral steroid treatment is used for nasal polyps when topical treatments like sprays or drops are no longer sufficient to control symptoms. While nasal steroids are the first line of defence, they can sometimes struggle to reach the polyps if the nasal passages are completely blocked. In the UK, a short course of oral steroids, typically prednisolone, is prescribed to provide a powerful, systemic anti inflammatory effect that targets the polyps from the inside out. This is often referred to by specialists as a medical polypectomy because it can shrink polyps so significantly that surgery may be delayed or even avoided.
Because oral steroids affect the entire body rather than just the nasal lining, they are reserved for specific clinical situations. In the UK, they are used sparingly and for short durations to minimise the risk of systemic side effects. Understanding the timing and purpose of this treatment is essential for patients managing chronic sinus disease.

Targeted use of oral steroids in the UK
In a UK ENT clinic, oral steroids are primarily used to treat severe cases of nasal polyps. The most common indication is a total loss of smell or a complete inability to breathe through the nose. When polyps are this large, they physically block the airway, preventing medicated sprays from reaching the deep tissue.
A short course of oral steroids allows the medication to circulate through the bloodstream and reach the core of every polyp. This results in rapid shrinkage, often restoring the sense of smell and opening the airway within just a few days. This window of improved airflow is then used to restart intensive topical treatments, which can now reach the newly opened nasal passages more effectively.
Pre-operative and emergency use
Oral steroids are also frequently used in the lead up to sinus surgery. By taking a course of prednisolone before a procedure, the inflammation in the nasal lining is reduced, and the polyps themselves become smaller and less vascular. This makes the surgery safer for the patient and easier for the surgeon, as there is less bleeding and a clearer view of the sinus anatomy.
In some cases, oral steroids are used as an emergency intervention when a patient experiences a severe flare up of symptoms, often following a viral infection. This rescue therapy helps to quickly resolve intense facial pain and pressure that has not responded to other treatments.
Managing side effects and duration
Common side effects of a short course may include:
- Increased appetite: Feeling hungrier than usual.
- Insomnia: Difficulty falling or staying asleep.
- Mood shifts: Feeling more irritable or anxious.
- Stomach irritation: Occasionally causing indigestion.
To reduce these risks, UK doctors advise taking the medication in the morning with food. If you are diabetic, you must monitor your blood sugar closely, as steroids can cause levels to rise significantly.
Comparison: Topical vs Oral Steroids
| Feature | Topical Steroids (Sprays/Drops) | Oral Steroids (Tablets) |
| Primary Action | Localised to nasal lining | Systemic throughout the body |
| Potency | Mild to moderate | Very high |
| Speed of Relief | Days to weeks | 24 to 48 hours |
| Duration of Use | Long term maintenance | Short term 1 to 2 weeks |
| Side Effects | Minimal e.g. dryness | Potential for systemic effects |
| Access in UK | Pharmacy or GP | Prescription only |
To Summarise
Oral steroid treatment is a powerful tool used by UK clinicians to manage severe nasal polyps that have become resistant to topical sprays. By providing a systemic anti inflammatory boost, medications like prednisolone can rapidly shrink large polyps, restore the sense of smell, and prepare the nose for more effective long term maintenance or surgery. While highly effective, their use is strictly limited to short courses to protect the patient from systemic side effects. This targeted approach ensures that the benefits of rapid relief are balanced with the need for long term safety.
If you find that your nasal polyps are causing a complete blockage or you have lost your sense of smell entirely, book an appointment with your GP to discuss whether a short course of oral steroids is appropriate for you.
How many times a year can I take oral steroids for polyps?
In the UK, most specialists prefer to limit oral steroid courses to no more than two per year. If you find you need them more frequently, it usually indicates that your maintenance treatment needs to be adjusted or that surgery should be considered.
Will my polyps come back after the tablets are finished?
Oral steroids are not a permanent cure. They provide temporary shrinkage. To prevent the polyps from growing back to their original size, you must continue using your nasal steroid sprays or drops exactly as prescribed once the course of tablets ends.
Can I stop taking the tablets early if I feel better?
You should always complete the course as directed by your doctor. If you have been on a high dose or a longer course, your GP may provide a reducing schedule to gradually taper the medication, which allows your body to adjust safely.
Can oral steroids help my asthma as well?
Yes. Since many people with nasal polyps also have asthma, a course of oral steroids will often significantly improve lung function and reduce wheezing at the same time it treats the nose.
Are there people who should not take oral steroids?
People with certain conditions, such as active infections, uncontrolled diabetes, or severe stomach ulcers, may need to avoid oral steroids. Your GP will check your medical history before prescribing them.
Do oral steroids cause permanent weight gain?
A short one to two week course for nasal polyps rarely causes permanent weight gain. Any slight increase in weight is usually due to temporary water retention or a temporary increase in appetite, which resolves once the medication is finished.
