What are the recommended first-line treatments for allergies in elderly patients?

From the Guidelines

First-line treatments for allergies in elderly patients typically include second-generation antihistamines such as cetirizine (10mg daily), loratadine (10mg daily), or fexofenadine (180mg daily) due to their reduced side effect profile compared to first-generation options. These medications cause less sedation and have fewer anticholinergic effects, making them safer for older adults. Intranasal corticosteroids like fluticasone (1-2 sprays per nostril daily) or mometasone (1-2 sprays per nostril daily) are also recommended for nasal symptoms, as they effectively reduce inflammation with minimal systemic absorption 1. Some key points to consider when treating elderly patients with allergies include:

• Starting with lower doses and adjusting gradually due to age-related changes in metabolism and potential drug interactions
• Avoiding first-generation antihistamines like diphenhydramine, which can cause confusion, urinary retention, and increased fall risk
• Considering the use of saline nasal irrigation for additional symptom relief without medication-related concerns
• Individualizing treatment based on symptom severity, comorbidities, and concurrent medications, with regular reassessment to minimize polypharmacy and adverse effects 1. It's also important to note that the combination of an intranasal corticosteroid and an intranasal antihistamine may be recommended for initial treatment of moderate to severe seasonal allergic rhinitis in persons aged 12 years or older 1. Overall, the goal of treatment should be to minimize symptoms and improve quality of life while minimizing the risk of adverse effects and drug interactions 1.

The recommended first-line treatment for allergies in elderly patients is not explicitly stated in the provided drug labels. However, cetirizine is indicated for indoor and outdoor allergies, providing 24-hour relief of symptoms such as sneezing, runny nose, itchy, watery eyes, and itchy throat or nose 2. Prednisone is indicated for control of severe or incapacitating allergic conditions, including seasonal or perennial allergic rhinitis, but it is not specified as a first-line treatment 3.

• Key points:
  • Cetirizine is an option for allergy treatment.
  • Prednisone is used for severe or incapacitating allergic conditions. It is essential to consult a healthcare professional for personalized recommendations, as the provided information does not directly address the question of first-line treatments for allergies in elderly patients.

From the Research

Recommended First-Line Treatments for Allergies in Elderly Patients

The recommended first-line treatments for allergies in elderly patients include:

• Second-generation antihistamines, such as cetirizine, fexofenadine, desloratadine, and loratadine, which are considered safer and more effective than first-generation antihistamines 4, 5, 6, 7
• Nasal glucocorticosteroids, which are also considered first-line therapies for allergic rhinitis in elderly patients 4
• Allergen-specific immunotherapy, which has been shown to be effective and safe in patients aged 60 years or older with allergic rhinitis 4

Considerations for Elderly Patients

When treating allergies in elderly patients, it is essential to consider the following:

• Age-related physiological changes, which can enhance or complicate the actions of H1-receptor antagonists 7
• Concomitant medications and potential drug-drug interactions and drug-disease interactions 7
• Renal and/or hepatic disease, which may require adjustments in dosages 7
• The potential for sedating and anticholinergic effects of first-generation antihistamines, which can be more pronounced in elderly patients 8

Safety of Antihistamines in Elderly Patients

The safety of antihistamines in elderly patients is a concern, particularly with regards to:

• First-generation antihistamines, which can cause sedation, impairment, and anticholinergic effects 5, 8
• Second-generation antihistamines, such as astemizole and terfenadine, which can cause serious cardiovascular adverse effects when taken in high doses or coadministered with certain medications 8
• The importance of selecting antihistamines that are safe and effective for elderly patients, such as loratadine and other second-generation antihistamines 5, 6, 7, 8
