Budesonide Nasal Spray Guide To Use, Side Effects, And FAQs
Relief from hay fever and nasal polyps: Comprehensive guide to using budesonide nasal spray safely and effectively.

Budesonide nasal spray, such as Benacort, is a corticosteroid medication designed to alleviate symptoms of allergic rhinitis (hay fever) and nasal polyps. It reduces inflammation in the nasal passages, easing congestion, sneezing, itching, and runny nose.
About budesonide nasal spray
Budesonide belongs to the corticosteroid group, which works by decreasing swelling and irritation in the nose. This provides relief from rhinitis symptoms including stuffy, runny, or itchy nose. Available by prescription or over-the-counter in smaller packs for hay fever, it is also used for nasal polyps—small growths in the nose causing similar symptoms.
The spray is for nasal use only and requires regular application for full effectiveness, often taking a few days to weeks to show optimal results. For hay fever, start before allergen exposure; for polyps, improvement may take 1-2 months.
Before using budesonide nasal spray
Consult a healthcare professional before starting, especially if you have certain conditions or take other medications.
- Recent nasal surgery or injury: Avoid until fully healed, as it may interfere with recovery.
- Infections: Not recommended for epistaxis, nasal ulcers, herpetic infections in nasal/oral/ophthalmic areas, or active/quiescent tuberculosis. Use only with concurrent antibacterial/antifungal treatment for bacterial/fungal nasal infections.
- Eye conditions: Inform your doctor if you have glaucoma, cataracts, or herpes eye infection.
- Pregnancy or breastfeeding: Use only on doctor’s advice.
- Children: Suitable for ages 12+ if prescribed; efficacy shown in studies for 6-16 years.
- Other medications: Check for interactions, especially other steroids, antifungals, or HIV treatments. High doses may require a steroid card.
- Allergies: Disclose any prior reactions to medicines.
