When you first start taking losartan potassium, do so as soon as possible after your doctor recommends it. As with other diuretics, however, don’t take it on an empty stomach. Wait at least 2 hours after eating before your dose is due to begin. If you’ve been using a diuretic for a long time and have developed high blood pressure or heart failure, discuss any possible risks or side effects with your doctor before starting this medication – especially if the doctor prescribes the drug without first doing some tests to determine whether you’re an appropriate candidate.
Losartan potassium may also be used for purposes not listed in this medication guide.
