In this session, we will be discussing the consumer medication information for losartan, trade name CozaarTM.
What it’s for & How to take
Losartan relaxes pressure on your blood vessels. This medication is used to treat high blood pressure. Losartan is also used to protect our kidneys from the damaging effects of diabetes and to decrease the risk of stroke in certain people.
Losartan is in a category of medications called ARB’s. ARB stands for angiotensin receptor blocker.
If high blood pressure is not treated, your blood vessels will harden, and this will eventually lead to a heart attack or a stroke. High blood pressure may also cause vision problems, kidney failure and eventually heart failure.
Losartan is usually taken once or twice daily. You may take this medication with or without food. Take losartan at the same time each day with a full glass of water.
If you forget to take a dose, take it as soon as you remember. If it is near the time of your next dose, skip it and continue with your normal dose time. Do not take a double dose to make up the missed dose.
Keep using this medication, even if you don’t feel sick. You may need to treat your high blood pressure for many years.
Your blood pressure should be checked often to make sure the medication is working correctly.
You may need to have regular blood tests done at the lab while taking this medication. These are done to see if you tolerate this medication.
