明确警告 meaning in Chinese

definite warning

As pharmaceutical products on the poisons list could cause harm to the users if they are not used in accordance with the dosage instructions , it is a statutory requirement for the containers of such products to be labelled with the word " poison " , or with a prescribed cautionary statement if the product carries specific risks or side effects which their users should be specifically cautioned against . such labelling arrangement has been in place since 1970
由于毒药表上的药剂制品在不按照剂量指示使用的情况下，可能会对使用者构成伤害，所以法例规定这些制品的容器上须附有标签标明毒药一词，或如果有关药物会引起某些特定的危险或副作用而须向使用者提出明确警告时，则须在标签上标明有关的警告说明。
