<p>Methyldopa should be used with caution in patients with a history of previous liver disease or dysfunction. Some patients taking Methyldopa experience clinical edema or weight gain, which may be controlled by use of a diuretic. Methyldopa should not be continued if edema progresses or signs of heart failure appear. Hypertension has recurred occasionally after dialysis in patients given Methyldopa because the drug is removed by this procedure. Rarely involuntary choreoathetotic movements have been observed during therapy with Methyldopa in patients with severe bilateral cerebrovascular disease. If these movements occur, stop therapy.</p>
