Pregnancy: Studies in animals have shown a teratogenic effect in one species and at high doses. There is currently no sufficient data to evaluate the possible malformative or foetotoxic effect of allopurinol when administered during pregnancy. Elevation of uric acid is frequently observed during pregnancy toxemia but does not require specific treatment. As a result, the use of allopurinol is not recommended during pregnancy. This element does not constitute the systematic argument for counseling a termination of pregnancy but leads to an attitude of caution and oriented antenatal surveillance.
