From the Guidelines
Yes, Kenalog (triamcinolone) is effective for treating seasonal allergies, particularly when administered as a nasal spray or injection. For nasal allergies, triamcinolone acetonide nasal spray (Nasacort) is typically used at a dosage of 1-2 sprays in each nostril once daily. For more severe seasonal allergies, a Kenalog injection (typically 40-80 mg) may be given, with effects lasting approximately 3-4 weeks. The nasal spray works locally to reduce inflammation in the nasal passages, while injections provide systemic relief throughout the body. Triamcinolone is a corticosteroid that works by suppressing the immune system's overreaction to allergens, reducing inflammation, and decreasing symptoms like sneezing, itching, runny nose, and congestion. Side effects may include nasal irritation with the spray or, with injections, potential temporary blood sugar elevation, mood changes, and reduced immune function. Kenalog injections are generally reserved for severe cases that don't respond to other treatments due to their systemic effects and should not be administered more than 3-4 times per year 1.
Key Points

Recommendations
- Use Kenalog (triamcinolone) for treating seasonal allergies, particularly when administered as a nasal spray or injection
- Follow the recommended dosage for triamcinolone acetonide nasal spray and Kenalog injections
- Monitor for side effects and adjust treatment as needed
- Reserve Kenalog injections for severe cases that don't respond to other treatments due to their systemic effects.
From the Research
Effectiveness of Kenalog for Seasonal Allergies
- Kenalog, also known as triamcinolone, is a synthetic glucocorticoid used to treat allergic rhinitis, including seasonal allergies 2, 3, 4.
- Studies have shown that intranasal triamcinolone acetonide is effective in reducing symptoms of seasonal allergic rhinitis, such as sneezing, rhinorrhoea, and nasal congestion 2, 3, 4.
- Triamcinolone acetonide has been found to be as effective as other intranasal corticosteroids, such as beclomethasone and fluticasone, in reducing symptoms of seasonal allergic rhinitis 2, 3.
- The use of intranasal triamcinolone acetonide has been recommended as a first-line therapy option for adults with moderately severe seasonal allergic rhinitis with predominantly nasal symptoms 2, 3.
Mechanism of Action
- Triamcinolone acetonide works by decreasing membrane permeability and inhibiting both early and late phase reactions to allergens, which helps to reduce the nasal secretory response and alleviate symptoms of seasonal allergic rhinitis 3.
- The topical application of triamcinolone acetonide also has a flushing action on the nasal mucosa, which may help to reduce allergens and secretions 3.
Safety and Tolerability
- Triamcinolone acetonide has been found to be well-tolerated in clinical trials, with common adverse effects including sneezing, dry mucosa, nasal irritation, and headache 2, 3, 4.
- The use of intranasal triamcinolone acetonide has not been associated with significant systemic absorption or suppression of the hypothalamic-pituitary-adrenal (HPA) axis function 2, 3.
- However, long-term use of intranasal corticosteroids, including triamcinolone acetonide, may be associated with rare complications such as bleeding, septal perforation, and nasal candidiasis 3.
