Hi ,welcome to healthcare magic
Formonide inhalor contains the active ingredient budesonide
.It is a commonly used inhalor. The most common side effects are:oral candidiasis
(washing the mouth out with water after the use of the inhalor reduces the chances of the thrush or hoarseness), allergic reactions, extremely high doses can potentially weaken the bones.
You are more likely to have problems related to uncontrolled asthma than to the use of the inhalors.
You can consider speaking to your doctor regarding any concerns that you may have.
I hope this helps
