Allergies in spring 2026: this popular drug threatens to be in short supply

Spring 2026 is upon us, and with it comes a whole host of inconveniences for millions of French people. If you’re among those affected by seasonal allergies, there’s some bad news that could complicate your daily life. A much-used medication is likely to run out in pharmacies.

Cetirizine shortage: what you need to know in 2026

Cetirizine is one of the most widely prescribed antihistamines in France. This medication effectively relieves symptoms linked to pollen, dust mites or animal hair. However, stocks have been dwindling for several weeks in many pharmacies.

The French National Agency for the Safety of Medicines (ANSM) is closely monitoring this situation. As a result, it has stepped up its monitoring of supplies. Tensions mainly concern generic forms, which are very much in demand in spring.

This shortage comes at a critical time of year. Grass pollens are reaching record peaks in several regions. As a result, demand is soaring while supply is falling.

“Patients need to anticipate their needs and consult their pharmacist to find suitable solutions.”

Why are we out of stock now?

Several factors explain this tense situation. Firstly, laboratories are facing difficulties in sourcing raw materials. In addition, worldwide production of active ingredients remains concentrated in a few countries.

Climate change also plays an indirect role. Pollen seasons are starting earlier and lasting longer. Production capacity, however, has not kept pace with these changes.

• Cetirizine still unavailable in 30% of French pharmacies
• Generics hardest hit by shortage
• Other antihistamines can be used as alternatives
• Pharmacists can offer therapeutic equivalents
• A prescription allows access to substitution treatments

Spring allergies: what solutions can help?

Faced with this shortage, alternatives exist to calm your symptoms. Loratadine or Desloratadine offer comparable efficacy. Your pharmacist can refer you to these non-prescription options.

Local treatments are also an interesting option. Nasal sprays and antihistamine eye drops act directly on irritated areas. They sometimes complement or replace tablets.

There are some simple steps you can take to reduce your exposure to pollens. Air your home early in the morning or late at night. Also, rinse your hair before going to bed to remove particles.

Wearing sunglasses protects your eyes outdoors. Many allergists now recommend this habit during pollen peaks. It limits frequent eye irritation.

When should I consult a doctor?

If your symptoms persist despite available treatments, make an appointment. A doctor can prescribe more powerful medications. He or she will also adapt the treatment to your profile.

Asthma sufferers need to be extra vigilant. A poorly controlled allergy can trigger respiratory attacks. Regular medical follow-up is therefore essential.

Desensitization remains an option for severe cases. This in-depth treatment reduces the immune system’s reactivity. It takes several years, but offers lasting results.

How do you anticipate and manage this shortage on a day-to-day basis?

Don’t delay in replenishing your stock of medicines. Pharmacists recommend two to three weeks in advance. This will prevent you from going without treatment.

Consult the pollen monitoring applications to adapt your outings. Some days present higher risks than others. So you can limit your exposure at critical times.

Air purifiers filter allergenic particles in your home. This investment brings relief to sensitive people. It improves indoor air quality all year round.

Finally, keep in touch with your local pharmacist. He or she can alert you as soon as a restocking is necessary. This relationship of trust makes it easier to manage your allergy on a daily basis.
