high blood pressure
"The combination of Cozaar with Atenolol has been highly effective in controlling my blood pressure, which had been intractable previously. After using the Cozaar brand name for some generic brand losartan. Over the next few months I developed a severe heartburn problem. I did not associate it with the change to the generic until a year later when certain other reasons I switched back to the brand name. Almost immediately my heartburn problem subsided. Please be aware of this if you are using a generic instead of Cozaar and you develop heartburn."
