Hi Dr. O,
My 11 yr old Hanoverian was diagnosed with Inflammatory Airway Disease most likely due to allergies, according to my vet. He has been on a nebulizer for about 15 days. The solution is 20cc of cromolyn sodium, salmeterol and budesonide. The first 10 days he got nebulized twice a day and he has been on once a day for the past 6 days. This is the first week that I have worked him on consecutive days, the last few weeks being light, intermittent work. I am still keeping his work light, but did trot him out a little longer than normal yesterday. When we got back to the barn, he had a slight nosebleed that lasted about a half hour and then stopped. Do you think the nosebleed is from the medication he is inhaling or from the exercise itself. I don't know whether to continue his treatments (we have about 7 days left) or stop riding him or both. My vet is away until Monday and I don't want to overlook something that could potentially be very serious. Any thoughts?

Hello Dana,
While we don't know the source / cause of the nosebleed, I think discontinuing riding, at least till he can be examined, is sensible. IAD can cause significant disease and I do not see a clear reason to stop them but this is not my judgement to make. To read more about the possible causes and their significance see HorseAdvice.com » Diseases of Horses » Respiratory System » Nose Bleeds: Epistaxis.

Dr. O,
Can those medications thin out his nasal passages, causing them to bleed? Have your heard any cases of the nebulizer causing nosebleeds? I did read the articles on nosebleeds, but I didn't see any information on nebulizers and their effects on the nasal passages.

Hello Dana,
I do not have personal experience with these medications and there is not a lot of information about this combination. Looking at the individual components they can be irritating in some individuals and the steroid component, budesonide, might overtime cause a thinning of the tissues. While nosebleeds are listed side effect it is used to treat conditions that cause nose bleeds also so I wonder if it is causal.
