The most common side effect of corten nasal spray is local irritation and burning sensation in the nasal mucosa.
Approximately 5 to 10% of patients who use this type of medication for more than two weeks develop some degree of nosebleeds with severe fining.
This complication resolves itself after 3 to 5 days of stopping the drug.
It is better to use the spray with a smaller amount after using it again and before that apply a moisturizing cream or nasal oil inside the nose.
Side effects of these drugs are very rare. Extensive research has been done in terms of adrenal gland suppression after the use of cortin nasal spray, which has not shown a connection.
It seems that in children, the use of these drugs is associated with a decrease in height growth.
A study for one year investigated the effect of mometasone, fluticasone and budesonide on children aged 3 to 11 years, which was not associated with any reduction in height growth.
Also, research has shown that these drugs are not associated with eye complications such as glaucoma and cataracts.
Therefore, corten nasal spray is a drug with few complications, safe and has a good therapeutic effect.
Corten spray should not be used in the middle part, close to the cartilaginous wall between the two noses (septum), because this area has poor blood supply and its vessels are narrowed due to contact with the steroid, which itself causes dryness and eventually nosebleeds.
