Hello Ms. Hartmann, the official label warning states that Streptokill is not suitable for children under 3 years of age. However, after consulting a doctor, Streptokill can also be used in younger children. Many of our customers successfully use Streptokill for children from one year. It is a 100% natural product containing, among other things, 58.6% alcohol, which is still the best natural preservative that will keep Streptokill for more than 2 years in excellent quality. Even in the case when small children with angina are sprayed with 20 doses every half hour per day, which is more than enough, it is only 2 ml of Streptokill per day (0.1 ml/1 dose), which represents only a negligible amount of alcohol. Best regards, Pavel Soukup
