Treatment approach for grass allergies
Environmental & Lifestyle Measures
- • Monitor pollen counts & avoid peak times (typically 10 am–5 pm).
- • Keep windows closed; use HEPA filters.
- • Shower & change clothes after outdoor exposure.
- • Mow lawns only when pollen is low, or wear protective gear.
Medications
- • Over-the-counter antihistamines (cetirizine, loratadine) and nasal corticosteroids (fluticasone).
- • Prescription options: stronger antihistamines, eye drops, decongestants, or a short course of oral steroids for severe cases.
Nasal Saline Rinses
Helps clear pollen from nasal lining. They are safe, gentle, and often effective.
Immunotherapy: Long-Term Relief
- • Allergy shots (SCIT): Gradually desensitize via injections over ~3 years. Benefits often last post-treatment.
- • Sublingual immunotherapy (SLIT): Daily dissolvable grass-pollen tablet taken at home; safer and well-tolerated.
