Discharge Instructions for Hypermagnesemia

You have been diagnosed with hypermagnesemia. This means you have too much magnesium in your blood. This can occur in people with kidney failure. It can also occur if you are given magnesium salts. And it can occur if you take a medication that contains magnesium. These include some antacids and laxatives. Below is what you need to know about home care.

Diet Changes

You will need to limit all foods that have magnesium. These include:

  • Dark green, leafy vegetables, including salad greens, collards, kale, and chard

Other Home Care

  • Tell your doctor about all the medications you take. Some may increase magnesium levels.

  • Take all medications as directed.

  • Do not drink alcohol. If you need help in stopping, ask your doctor about programs in your area.
