From the Guidelines

I strongly advise against a 15-year-old taking 40 mg of Kenalog for seasonal allergies without medical supervision. According to the 2017 joint task force on practice parameters, for initial treatment of seasonal allergic rhinitis in persons aged 15 years or older, an intranasal corticosteroid is recommended over other treatments 1. This approach prioritizes minimizing potential side effects and maximizing efficacy. For a 15-year-old, first-line treatments typically include over-the-counter antihistamines like cetirizine, loratadine, or fexofenadine, along with nasal steroid sprays like fluticasone.

Key Considerations

  • Kenalog is a potent corticosteroid that requires a prescription and proper dosing from a healthcare provider based on the individual's specific condition, weight, and medical history.
  • Kenalog injections can cause serious side effects in adolescents, including growth suppression, adrenal gland problems, increased risk of infections, and bone density issues, as noted in general medical knowledge.
  • The guideline developed using the GRADE method addresses specific recommendations regarding initial pharmacotherapy approaches for patients aged 12 years or older with seasonal allergic rhinitis, emphasizing the importance of evidence-based treatment decisions 1.

Recommended Approach

  • For initial treatment, consider over-the-counter antihistamines and nasal steroid sprays.
  • If symptoms persist, consult a pediatrician or allergist for personalized guidance on prescription treatments.
  • Intranasal corticosteroids are preferred for initial treatment in individuals aged 15 years or older 1.

From the FDA Drug Label

Allergic states: Control of severe or incapacitating allergic conditions intractable to adequate trials of conventional treatment in asthma, atopic dermatitis, contact dermatitis, drug hypersensitivity reactions, perennial or seasonal allergic rhinitis, serum sickness, transfusion reactions. The answer to whether a 15-year-old can take 40 mg Kenalog for seasonal allergies is:

  • Yes, Kenalog-40 Injection is indicated for the control of severe or incapacitating allergic conditions, including seasonal allergic rhinitis. However, the decision to administer Kenalog should be made by a healthcare professional, considering the individual patient's needs and medical history 2.
