Modern nasal steroids such as Beconase™ , Rhinocort® , Flixonase™ and Nasonex® are proven safe for long term treatment. They should not be confused with dangerous anabolic steroids abused by some athletes – you will be perfectly eligible for the Olympics on these treatments. Potential side-effects of being “on steroids” are minimal because the total dose is small, and very little of the small dose taken is absorbed into the body. However, you might get local side-effects, such as nosebleeds. Occasionally, nosebleeds can be bad enough to stop you taking nasal steroids.
