In dispensing any medicine containing any of the substances mentioned in the following schedule, registered chemists, apothecaries, and medical practitioners in Great Britain do not require to label the medicine 'Poison' (in Ireland medical practitioners must label), but the name and address of the seller must be given in all cases. The ingredients of prescriptions containing any scheduled poison must be entered with 'the name of the person to whom it is sold or delivered in a book kept for that purpose.'The name of the person for whom it is sold (i.e., the patient) or of the person to whom it is delivered (i.e., the patient's agent) may be entered, said Mr. Justice Lush in 'Berry v. Henderson,' a legal case which bears upon the matter. In the Poisons Act (Ireland) these conditions were applied to apothecaries, and the 1875 Act extended them to pharmaceutical chemists and legally qualified medical practitioners. It should be noted that prescriptions containing arsenic are only subject to the dispensing exemption when they are written by a duly qualified medical practitioner.
