<p>Nelfinavir should not be administered concurrently with Terfenadine, Astemizole, Cisapride, Triazolam, Midazolam, Ergot derivatives, Amiodarone or Quinidine because Nelfinavir may affect the hepatic metabolism of these drugs and create potential for serious and/or life-threatening adverse events. New onset diabetes mellitus, exacerbation of pre-existing diabetes mellitus and hyperglycaemia have been reported during post-marketing surveillance in HIV-infected patients receiving protease inhibitor therapy. Some patients required either initiation or dose adjustments of insulin or oral hypoglycaemic agents for treatment of these events. In some cases diabetic ketoacidosis has occurred. In those patients who discontinued protease inhibitor therapy, hyperglycaemia persisted in some cases.<br />
<br />
<strong>General:</strong>&nbsp;Nelfinavir is principally metabolised by the liver. Therefore, caution should be exercised when administering this drug to patients with hepatic impairment.<br />
<br />
<strong>Haemophilia:</strong>&nbsp;There have been reports of increased bleeding, including spontaneous skin haematomas and haemarthrosis, in patients with haemophilia type A and B treated with protease inhibitors. In some patients, additional factor VIII was given. In more than half of the reported cases, treatment with protease inhibitors was continued or reintroduced. A causal relationship has not been established.</p>
