Losartan Dosing

For those who are treating diabetic nephropathy with losartan, dosing recommendations typically start at 50 mg once a day. Depending on your response to the medication, your healthcare provider may choose to alter your dosage accordingly. The recommended starting dosage for those with high blood pressure is 50 mg once daily, with a final daily dose between 25 mg and 100 mg. Children who are being treated for high blood pressure usually start with 0.7 mg per kilogram of body weight once a day.

 

Losartan Dosing: An Introduction

The dose of losartan potassium (Cozaar®) that your healthcare provider recommends will vary depending on a number of factors, including:
 
  • The medical condition you are being treated for
  • Other medical conditions you may have
  • Other medications you may be currently taking
  • How you respond to losartan.
     
As is always the case, do not adjust your dose unless your healthcare provider specifically instructs you to do so.
