How much potassium is in losartan? Is there a lot of potassium in the 25mg, 50mg or 100mg tablets?
There is not enough potassium in any strength of losartan to have any effect on potassium levels in the body. “losartan potassium” is just the full name of losartan.
Losartan is a blood pressure medication known as an ARB. ARBs help the blood vessels in the body relax which then decreases blood pressure.
However, the medication can cause the body to retain potassium. This increase in potassium could cause serious side effects. That is the reason your health care provider will check labs from time to time. It is not potassium from the tablets, but the action of the medicine that can cause the build up in the body. High potassium [hyperkalemia] is rare with losartan.
If you are concerned about your potassium be sure to talk to your prescriber. It is a common question at the pharmacy and I’m glad you are educating yourself about your medication.
