Allergies and Hay Fever in France: Treatment Guide for Expats and Visitors
Pollen season in France peaks April–July. If your eyes are streaming and your nose won't stop, here's how to get relief — fast.
Allergy season in France
France has a significant pollen season running from February (trees) through October (grasses, moulds). The main culprits: birch, grass pollen, and ragweed (ambroisie), which has spread significantly across southern France and the Rhône valley. Paris and the Loire Valley see peak grass pollen in May–June.
OTC allergy treatments available without prescription
French pharmacies stock a full range of antihistamines and nasal sprays without prescription:
- Oral antihistamines: cetirizine (Zyrtec), loratadine (Clarityne), desloratadine (Aerius) — all available OTC in France
- Nasal sprays: saline sprays freely available; some corticosteroid nasal sprays (Nasacort, Rhinocort) are now OTC in France
- Eye drops: antihistamine eye drops (Kétotifène) available OTC
When you need to see a doctor
OTC treatments work for most people. See a doctor if:
- OTC antihistamines aren't controlling your symptoms after 2 weeks
- You develop chest tightness, wheezing or shortness of breath (possible asthma — needs assessment)
- You have a fever (allergies don't cause fever — it may be sinusitis or infection)
- You need prescription-strength corticosteroid treatment or allergy testing
- You want to explore immunotherapy (desensitisation) — this requires specialist referral
Allergy testing in France
Allergy testing (bilan allergologique) requires a referral to an allergist (allergologue). Wait times for allergist appointments in France can be 3–6 months in public sector. Private allergists are faster. An online GP consultation can provide the referral letter and in the meantime prescribe effective management.
