Adults and children 12 years and over: One tablet daily. Avoid use in pregnancy and breast feeding. Please carefully read all product packaging and label information prior to use. Please note that as this product is marketed as a 12 month supply, the expiry dates on the product are only required to have at least 12 months on them. For example, ordering 5 x 12 month supplies does not constitute as a five year supply as we are unable to guarantee expiry dates longer than about 2 - 3 years. Please note that this product may come as Cetirizine Hydrochloride / Dihydrochloride. The two work in the same manner and whilst they are structurally different this does not effect the relief provided by the drug. We cannot accept any wrong item returns from complaints regarding the above.
