You should not use this medication if you have kidney failure, a urinary tract infection, uncontrolled diabetes, a peptic ulcer in your stomach, Addison's disease, severe burns or other tissue injury, if you are dehydrated, if you take certain diuretics (water pills), or if you have high levels of potassium in your blood (hyperkalemia).

You should not take potassium citrate tablets if you have problems with your esophagus, stomach, or intestines that make it difficult for you to swallow or digest pills.

Do not crush, chew, break, or suck on an extended-release tablet. Swallow the pill whole. Breaking or crushing the pill may cause too much of the drug to be released at one time. Sucking on a potassium tablet can irritate your mouth or throat.

Avoid lying down for at least 30 minutes after you take this medication.

Take this medication with a meal or bedtime snack, or within 30 minutes after a meal.

To be sure this medication is helping your condition, your blood may need to be tested often. Your heart rate may also be checked using an electrocardiograph or ECG (sometimes called an EKG) to measure electrical activity of the heart. This test will help your doctor determine how long to treat you with potassium. Do not miss any scheduled appointments.

Serious side effects of potassium citrate include uneven heartbeat, muscle weakness or limp feeling, severe stomach pain, and numbness or tingling in your hands, feet, or mouth.

Do not stop taking this medication without first talking to your doctor. If you stop taking potassium suddenly, your condition may become worse.
