Budesonide: Uses, How It Works, Medicines
Budesonide is an inhaled steroid used as a preventer in asthma. It reduces swelling in the airways when used regularly, so that symptoms occur less often. It does not relieve a sudden attack, so a separate reliever inhaler is usually also needed. It is a prescription medicine and should not be stopped suddenly without speaking to a doctor.
Also known as: Budesonide inhaler, Budesonide steroid inhaler, Pulmicort, Budecort

How does Budesonide work?
Budesonide is a corticosteroid that acts directly in the lungs. It calms the swelling in the airway lining, so the airways are less sensitive and less likely to tighten.
How to take Budesonide
Follow the label or your doctor's advice. It is used regularly, even when you feel well. Follow the pack leaflet and your doctor's instructions for the inhaler technique and any spacer.
Side effects of Budesonide

When the label says not to use it

Medicines and things that interact with Budesonide
Budesonide can be used with many medicines, but a few change its effect. Tell your doctor or pharmacist about everything you take, including other steroids and herbal remedies.
- Other steroid medicines (tablets, injections, creams): the total steroid effect may be higher
- Some antifungal medicines such as ketoconazole and itraconazole, and some HIV medicines: they can raise the level of budesonide in the body
- Other breathing medicines: ask your doctor before changing how you use them
If someone takes too much
Using too much budesonide at one time is unlikely to cause harm. Using much more than advised over a long time can cause steroid side effects. If you are worried, talk to your doctor or pharmacist, or go to the nearest hospital and take the inhaler with you.

Common questions
What is budesonide used for?
Inhaled budesonide is a steroid preventer used regularly to reduce airway swelling and lower the chance of asthma symptoms. A doctor decides whether it suits you and how it should be used.
Is budesonide a reliever?
No. It works over days and weeks and does not stop a sudden attack. Keep your reliever inhaler for sudden symptoms, as your doctor advised, and get emergency help if breathing is very difficult.
Why should I rinse my mouth after using it?
Some medicine stays in the mouth and throat and can cause thrush, soreness or a hoarse voice. Rinsing with water or brushing your teeth after each use may help. Tell your doctor if you see white patches in your mouth.
Can I stop budesonide when my asthma is better?
Do not stop on your own. Feeling better usually means it is working, and stopping suddenly can bring symptoms back. Talk to your doctor or nurse, who decides whether any change is suitable.
Is Budecort the same as budesonide?
Budecort is a brand name for inhalers containing budesonide. Check the strength and device on the pack. Some inhalers contain budesonide together with another medicine, so check the ingredient list before switching.
