Active ingredient: See product packaging and patient information leaflet for the exact active antihistamine and dosage used in the market you are purchasing from. Different markets may supply Duolerg with antihistamine actives commonly used for allergy relief (dosage strengths vary by region).

Inactive ingredients (excipients): Tablet excipients vary by manufacturer and region. Check the printed label for a full list of inactive ingredients and potential allergens (for example lactose, gluten, dyes, or preservatives) if you have specific ingredient sensitivities.

Always read the included leaflet for the confirmed active ingredient, strength and a complete ingredient list before use.

Follow the directions on the packaging or the advice of your healthcare professional. Typical guidance for oral antihistamine tablets includes:

• Adults and adolescents: take as directed on the label—often one tablet once daily (do not exceed the recommended daily dose).
• Take with a full glass of water. Tablets are usually taken with or without food.
• If symptoms persist despite use, consult your pharmacist or doctor for advice.
• Do not combine with other antihistamine products unless advised by a healthcare professional.

Duolerg is intended for people seeking relief from seasonal allergy symptoms and hay fever, including adults and eligible adolescents. It can be used for allergic rhinitis triggered by pollen, grasses, dust, pet dander and other common allergens. Not all formulations are suitable for young children—refer to packaging or speak with your pharmacist for child-appropriate options.
