This volume contains recommended quantities, indications and dosing for 55 medicines listed in the<i>International Medical Guide for Ships</i> Third Edition. The quantities are based on three types of ships:<br><br>-ocean-going ships with crews of 25-40 and no doctor (Category A); <br>-coastal ships with crews of up to 25 that travel no more than 24 hours from a port of call (Category B);<br>-small boats and private craft with crews of 15 or less, and usually travelling no more than a few hours from a port of call (Category C).<br><br>These quantities have been updated to reflect the decrease of crew numbers on most ships and calculated for voyages of one month. This companion volume to the<i>International Medical Guide for Ships</i> provides essential guidance to all those who involved in the procurement, purchasing, stock maintenance and use of medicines to promote and protect the health of seafarers worldwide.
