Originally designed by Sotiris Antoniou of the pharmacy department at the Barts and The London Heart Centre, the antiplatelet card has been endorsed by the British Cardiovascular Society and British Cardiac Intervention Society. The UKCPA is making the card available to ensure that patients have written information on the reason why an antiplatelet drug has been started, their daily dose, the drug s concurrent use with aspirin and the planned duration of therapy. The card also provides details on possible adverse effects and potential interactions with other medicine, and highlights the need to consult a doctor before any surgical procedures.
