Potassium citrate
Also known as: Cystopurin, Potassium citrate BP
Administer with food to minimize gastrointestinal upset. Ensure your pet has access to plenty of fresh water at all times. Do not change the dose without consulting your veterinarian, as too much can cause dangerous changes in blood potassium levels or urine pH. Contact your vet if you notice vomiting, diarrhea, weakness, or changes in urination.
Dosage must be set by your veterinarian for your specific pet. Never give human medication or another pet’s prescription without veterinary guidance.
What it is used for
How it is given
Possible side effects
- Gastrointestinal upset (nausea, vomiting, diarrhea)
- Hyperkalemia (rare if renal function is normal)
Cautions & contraindications
- Renal failure or severe renal impairment
- Hyperkalemia
- Metabolic alkalosis
- Struvite urolithiasis (requires acidic urine)
- > **Monitor serum potassium** levels, especially in patients with compromised renal function or those on concurrent medications that increase potassium. > **Monitor urine pH** to ensure target alkalinity (typically pH 7.0-7.5) is achieved without over-alkalinizing, which could predispose the patient to calcium phosphate or struvite crystal formation.
Drug interactions
- Spironolactone: Increased risk of hyperkalemia due to potassium-sparing effects
- ACE inhibitors (e.g., Benazepril, Enalapril): Increased risk of hyperkalemia
- NSAIDs: May increase the risk of hyperkalemia in compromised patients
