Cozaar, also known by its generic name Losartan potassium, is a medication used to treat two main conditions:

  • High blood pressure (hypertension): Cozaar helps relax blood vessels, allowing blood to flow more easily and lowering your blood pressure. This can help reduce the risk of strokes, heart attacks, and kidney problems.
  • Kidney disease in people with type 2 diabetes: In individuals with type 2 diabetes, Cozaar can help slow the progression of kidney disease by reducing protein leakage in the urine.


  • Take Cozaar as prescribed by your healthcare provider, typically starting with one 50 mg tablet taken once a day. 
  • Do consider starting with a lower dose for some patients, with adjustments based on blood pressure readings. Most patients take between 25 to 100 mg each day, either as a single dose or in divided doses. For type 2 diabetes mellitus with protein in the urine, the usual starting dose is one 50 mg tablet taken once a day, which may be increased to 100 mg once a day based on blood pressure.  
  • Use Cozaar regularly at the same time each day to get the most benefit from it. 
  • Take Cozaar by mouth with or without food as directed by your healthcare provider. 
  • Shake the bottle well before each dose if using the liquid form. 
  • Measure the dose carefully using a special measuring device/spoon. 
  • Keep taking Cozaar even if you feel well, as high blood pressure often has no symptoms.



  • Do not adjust the dosage of Cozaar without consulting your healthcare provider. 


Common Side Effects of Cozaar:

  • Dizziness or lightheadedness, especially when you first start taking the medication or when the dose is increased

  • Low blood pressure, which can make you feel dizzy, lightheaded, or faint
  • Kidney problems, including swelling of the hands and feet
  • Allergic reaction, which can cause symptoms such as rash, itching, and swelling of the face, lips, or tongue
