Cats with breathing problems often need corticosteroids to control inflammation. Budesonide and prednisolone are two of the most common options.
Most vets pick budesonide for long-term use because cats inhale it, so there are fewer side effects than with oral prednisolone.
Prednisolone goes by mouth and usually works fast, but it brings a bigger risk of side effects, especially with long-term use.
Budesonide targets the lungs directly when inhaled, which makes it a softer choice for cats with ongoing asthma or bronchitis.
Here’s a look at how budesonide and prednisolone work, how they’re different, and which one might help your cat breathe easier.
Comparing Budesonide and Prednisolone for Cats
Both budesonide and prednisolone are steroids that reduce inflammation in cats.
They work in different ways and bring their own set of benefits and risks.
Knowing how each one is given and how it affects your cat can really help you and your vet decide on the right treatment.
Mechanisms of Action
Budesonide and prednisolone both fight inflammation, but they act in different places.
Budesonide mostly stays local in the gut, where it reduces inflammation with less effect on the rest of the body.
That’s handy because it keeps side effects down.
Prednisolone takes a broader approach.
It goes everywhere through the bloodstream and calms inflammation all over.
That makes it useful for lots of conditions, but also brings more side effects.
Vets often use budesonide for issues like inflammatory bowel disease in cats.
They reach for prednisolone when a cat needs help with asthma or strong allergic reactions.
Common Uses in Feline Medicine
Budesonide is a solid choice for cats dealing with stubborn gut inflammation, like inflammatory bowel disease.
It calms things down but doesn’t hit the whole body as hard as some other steroids.
Prednisolone is more of a go-to for different problems.
It handles asthma, skin allergies, and autoimmune stuff pretty well.
It works fast, but you need to keep a close eye on your cat for side effects.
For cats with asthma or chronic bronchitis, inhaled budesonide is often the favorite.
It goes straight to the lungs and avoids some of the bigger risks, like diabetes or adrenal issues, that come from pills.
Differences in Side Effects
Prednisolone can cause more serious side effects because it affects the whole body.
Cats taking oral prednisolone may drink and pee more, gain weight, or even develop diabetes if they’re on it for a long time.
Budesonide usually brings fewer and milder side effects since it mostly stays where it’s needed.
Still, if you give a high dose or use it for a long stretch, some side effects can pop up.
Both drugs can mess with the adrenal system.
Prednisolone is more likely to cause adrenal suppression, so vets need to keep an eye on things no matter which steroid is used.
Dosing and Administration
Prednisolone usually comes as a tablet or liquid.
Your vet will set the dose based on your cat’s weight and what’s going on.
Pharmacies can compound it to make dosing easier.
Budesonide can be given as a pill or through an inhaler.
The inhaler needs a special device to get the medicine into the lungs, which works well for asthma.
Pharmacies can also make budesonide tablets in the right strength.
The idea with budesonide is to get enough medicine to the problem area without flooding the whole body.
With prednisolone, you have to balance the benefits and side effects pretty carefully.
