What Is Potassium Citrate For?
(Potassium Citrate Tablets (www.drugs.com))

Potassium Citrate is used for the treatment and management of various medical disorders, such as uric acid or cystine kidney stones, renal tubular acidosis, gout and Hypokalemia (a condition where the blood has a low amount of potassium concentration). Potassium citrate is part of the urinary alkalinizer drug class, and is often administered to patients who must limit their potassium and sodium intake. It may also be administered to boost the effectiveness of a number of antibiotics.


As an alkalinizing agent, potassium citrate operates as a urinary pH modifier, making the urine less acidic by neutralising some of its acid. The urine pH is utilised to categorise urine as being a base solution or a dilute acid. A lower pH level signifies the higher acidity of a solution, whereas a higher pH level indicates a greater alkalinity. On the pH scale, seven is considered to be neutral; contingent upon a person's acid-base rank, the pH level of their urine tends to span anywhere from 4.5 to 8.


Kidneys are responsible in making sure that the body maintains a healthy acid to base ratio. Their ability to discharge acid and alkaline via the urine is critical when it comes to the overall ability to uphold a stable body pH. Urine can turn more and more acidic as the quantity of sodium and surplus acid kept by the body increases. This is where potassium citrate demonstrates its effectiveness—helping the kidneys to neutralise and eliminate uric acid, thus preventing a number of conditions that can result from kidney disease and related problems.


Potassium citrate is quickly absorbed when taken orally and gets excreted from the urine as a salt of carbonic acid. This makes it effective in lowering the pain and frequency of urination that’s caused by high acidic levels. Potassium citrate also acts as a diuretic by forcing the body to excrete urination in a timely manner. Since it makes the urine alkaline, it can also be employed to decrease the risk of crystals in the urine.

Usage & Dosage

Potassium citrate comes in the form of tablets, which are generally taken three to four times a day with a full glass of water and food to coat the stomach. Individual dosages may vary according to a person’s specific condition and their overall response to the treatment. Doctor’s usually require patients on potassium citrate to undergo periodic blood work and an electrocardiograph (ECG) to test their heart function. Such tests also help the doctor to determine how long a patient needs to take potassium citrate.


As with any medication, potassium citrate can cause side effects, which may include nausea, vomiting, a tingling sensation in the hands and feet, stomach upset and diarrhoea. Adverse reactions to the medication include increased confusion or agitation, irregular heartbeat, continuous vomiting, trouble breathing, numbness of the mouth, stomach pain and muscle weakness. Potassium citrate may adversely affect or interfere with other prescription medications and over-the-counter remedies. Prior to starting any medication, it’s important to notify your doctor of any medications you’re taking, pre-existing medical conditions you have and allergies.
