    Where drugs having similar physiological actions occur in combination, the dosage of each shall be proportionately reduced.

    Accurate dosagesmay be expressed in either metric units or imperial units. If the dosage is expressed in both systems, then an approximation may be used for one expression, but such approximation must precede or follow the accurate statement by which the product will be judged and must be in brackets.
