What is the most important thing I should know about LOKELMA?

LOKELMA can cause swelling (edema) caused by fluid retention in your body (such as hands, ankles, feet).

  • LOKELMA contains 400 mg of sodium in each 5 g dose. Watch for signs of swelling in your body especially if you limit sodium in your diet or are likely to have fluid retention in your body due to heart or kidney problems. Your doctor may tell you to reduce the sodium in your diet.
  • If you are not on dialysis, your doctor may also tell you to increase the dose of your diuretic.

If you are a hemodialysis patient:

  • Do not take LOKELMA on dialysis days.
  • Tell your doctor if you suddenly feel sick such as decreased oral intake of food or fluids or diarrhea, as you may be at risk of developing low levels of potassium in your blood while on LOKELMA; therefore, your dose of LOKELMA may need to be adjusted.

What should I tell my doctor before taking LOKELMA?

Before taking LOKELMA, tell your doctor about all your medical conditions, including

  • problems having a bowel movement, including severe constipation, a blockage (obstruction) in your bowel, or dry hard stool that will not pass out of your rectum (impaction).
  • problems with your bowels after surgery.
