What is budesonide nasal spray used for?
Back to contentsBudesonide nasal spray is a type of corticosteroid used to prevent or ease rhinitis. This is a condition where the inside of your nose becomes inflamed and irritated. It is commonly caused by allergies, such as hay fever.

If you have an infection in your nose.
If you have recently had any surgery on your nose.
If you have tuberculosis (TB).
If you are pregnant. This is because, while you are expecting a baby, you should only take medicines on the recommendation of a doctor.
If it is intended for a child. Budesonide is suitable for children over the age of 12, but only if it has been prescribed by a doctor.

If you have ever had an allergic reaction to a medicine.
How to use budesonide nasal spray
Back to contentsRead the manufacturer's instructions to make sure you know how to work the spray.
Shake the bottle and remove the protective cap. (Before you use the spray for the first time, activate the spray a few times until you can see a fine mist in the air.)
Blow your nose gently to clear it.
Close one nostril by placing a finger against one side of your nose. Then, using your other hand, put one finger on each side of the nozzle of the bottle and insert the nozzle into your open nostril. Try to keep the bottle upright as you do this.
Activate the spray by pushing down on the collar around the bottle. Repeat if you are using two sprays for each dose.
Repeat the step above in your other nostril.
Wipe the nozzle with a clean tissue and replace the cap. (If the nozzle becomes blocked, you can remove it from the bottle and rinse it under warm water.)
Getting the most from your treatment
Back to contentsRead the patient leaflet before use. It explains how to use the spray and lists possible side effects.
Use as directed by your doctor or pharmacist. The usual starting dose is two sprays in each nostril once daily, or one spray in each nostril twice daily. Once symptoms are controlled, the dose may be reduced. Treatment may continue for up to three months.
For hay fever, start early if advised. Using the spray 2–3 weeks before the pollen season can help prevent symptoms from developing.
Use the spray regularly. If you miss a dose, take it when you remember unless your next dose is due. Do not take two doses to make up for a missed dose.
Do not exceed the recommended dose or treatment duration. This may increase the risk of side effects.
