About budesonide nasal spray

Type of medicine


Used for

Nasal symptoms caused by allergies; nasal polyps

Also called


Available as

Nasal spray

Budesonide nasal spray is used to prevent or ease rhinitis. This is a condition where the inside of your nose becomes inflamed and irritated. Common symptoms include sneezing, a blocked or congested nose, a runny nose (watery discharge), and an itchy nose. It is commonly caused by allergies, such as hay fever. Budesonide belongs to a group of medicines called corticosteroids. It reduces inflammation and swelling and so relieves the congestion, itching, sneezing, irritation and discomfort of rhinitis. Budesonide nasal spray is prescribable by a doctor. You can also buy smaller packs at a pharmacy, without a prescription, for the treatment of hay fever.

Budesonide nasal spray is also prescribed as a treatment for nasal polyps. Polyps are small growths inside the nose that can cause symptoms similar to allergic rhinitis.

Before using budesonide nasal spray

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start using budesonide, it is important that your doctor or pharmacist knows:

  • 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 are taking or using other medicines. This includes any medicines you are taking which are available to buy without a prescription, as well as herbal and complementary medicines.

  • If you have ever had an allergic reaction to a medicine.

How to use budesonide nasal spray

  1. Read the manufacturer's instructions to make sure you know how to work the spray.

  2. 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.)

  3. Blow your nose gently to clear it.

  4. 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.

  5. Activate the spray by pushing down on the collar around the bottle. Repeat if you are using two sprays for each dose.

  6. Repeat the step above in your other nostril.

  7. 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

  • Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. This will give you a step-by-step guide of how to use the spray, and will also provide you with a full list of the side-effects which you may experience from using it.

  • When you first start using budesonide, it is usual to use either two sprays into each nostril each morning, or one spray into each nostril twice a day. Your doctor or pharmacist will tell you which is right for you. Once your symptoms are controlled, you may be advised to reduce this to just one spray into both nostrils once a day. Treatment with budesonide may be continued for up to three months, but your doctor will advise you how long is right for you.

  • If you are using the spray for hay fever, your doctor may recommend that you start using it 2-3 weeks before the hay fever season starts. This is because it takes a few days of treatment before you feel the full effect, so starting before the pollen count rises will help to prevent symptoms from developing.

  • Try to remember to use budesonide spray regularly, even if your symptoms are controlled. If you forget a dose at your usual time, take it as soon as you remember unless your next dose is due. If your next dose is due then have the dose which is due and leave out the forgotten one. Do not 'double up' to make up for a missed dose.

  • Do not use the spray more often, or for a longer period of time, than is recommended by your doctor or pharmacist. This could increase the risk of side-effects.
