More Details

A syrup containing potassium citrate, magnesium citrate, and vitamin B6 is a medication primarily used to treat and prevent kidney stones. It is available under several brand names and works by altering the urine's pH to create an environment less favorable for stone formation. This medication requires a prescription in most regions and should only be taken under a doctor's supervision. 

How it works

The three active ingredients work together to prevent the formation and aggregation of crystals in the kidneys. 

  • Potassium citrate and magnesium citrate: These are urinary alkalinizing agents. They raise the pH level of the urine, making it less acidic. This helps prevent the formation of calcium oxalate and uric acid stones.

  • Vitamin B6 (Pyridoxine): A deficiency of this vitamin is associated with an increased production of oxalate, a key component of certain kidney stones. Adding vitamin B6 to the formula helps reduce oxalate levels. 

Uses and benefits

In addition to preventing kidney stones, this medication is also used for other conditions: 

  • Renal tubular acidosis (RTA): It helps correct the body's acid-base balance in patients with RTA, a condition where the kidneys fail to properly excrete acids.

  • Urinary discomfort: It can provide relief from a burning sensation during urination, which is often caused by acidic urine.

  • Electrolyte balance: It helps regulate potassium and magnesium levels in the body.

  • Gout: It can be used as part of the treatment for gout. 

Potential side effects

While most people tolerate the medication well, some may experience side effects. Common side effects include: 

  • Abdominal discomfort

  • Diarrhea

  • Nausea and vomiting

  • Stomach pain 

More serious, but less common, side effects should be reported to your doctor immediately: 

  • Symptoms of high potassium levels (hyperkalemia), such as muscle weakness, confusion, or an irregular heartbeat.

  • Gastrointestinal bleeding, indicated by bloody or black, tar-like stools. 

Precautions and warnings

Before taking this medication, discuss your medical history with your doctor. This syrup is not suitable for everyone and has several contraindications: 

  • Kidney problems: It is not recommended for people with severe kidney impairment due to the risk of dangerously high potassium levels and soft tissue calcification.

  • High potassium levels (hyperkalemia): Patients with pre-existing high potassium levels should not take this medication.

  • Gastrointestinal issues: Those with a history of peptic ulcers or conditions affecting gastric emptying or bowel function should avoid this medication.

  • Pregnancy and breastfeeding: The safety of this medication during pregnancy is not fully established, and pregnant women should only use it if specifically advised by a doctor. 

  • Dosage and administration

    • Always take this medication exactly as directed by your doctor.

    • The recommended dose should always be diluted with a full glass of water before consumption.

    • It is generally advised to take the syrup after meals to reduce the risk of stomach upset.

    • Avoid consuming foods high in potassium and oxalates while on this medication, as directed by your doctor.
