Approved indications
Fexofenadine is a non-drowsy antihistamine used to relieve hay fever and allergic rhinitis symptoms — including sneezing, runny nose, and itchy or watery eyes — and to help manage hives when needed.
Contraindications (do not use if…)
Do not take fexofenadine if you have had a serious allergic reaction to any ingredient in the product. Age restrictions apply — follow the formulation-specific guidance.
Important precautions
Some fruit juices (apple, orange, grapefruit) can reduce how much fexofenadine your body absorbs. Follow the product instructions about food, juice, and timing alongside antacids.
Common side effects
Common side effects include headache, nausea, dizziness, and tiredness. Drowsiness is less likely than with older antihistamines but can still happen.
Serious side effects — seek urgent medical care
Severe allergic reactions are rare but require emergency help. Get advice for any unexpectedly severe symptoms or a marked change in alertness.
Important interactions
Aluminium- or magnesium-based antacids and some fruit juices can reduce absorption. Check the leaflet for timing instructions and ask your pharmacist about other medicines.
Allergy considerations
Avoid fexofenadine if you have had a serious reaction to it or any ingredient in the product.
