Patients with hypersensitivity to budesonide or any other ingredients in Rhinocort should avoid using it. Discuss with a healthcare provider if you have a history of liver or kidney disease, are pregnant or breastfeeding, or if using other medications that might interact with corticosteroids.

Common Mistakes Patients Make

A common mistake is inconsistent dosing or abrupt cessation of the drug which can reduce effectiveness or increase side effects. Always follow the prescribed regimen and consult with a healthcare provider for any concerns.
