Can't find Citric Acid/Sodium Citrate? Learn about real alternatives like Potassium Citrate, Sodium Bicarbonate, and Tricitrates that your doctor may prescribe.
When your pharmacy tells you Citric Acid/Sodium Citrate is out of stock — and you've already tried every trick in the book — it's time to talk to your doctor about alternatives.
The good news is that there are several other medications that work in a similar way. In this article, we'll explain what Citric Acid/Sodium Citrate does, how it works, and which alternatives might be right for you.
Important: Never switch medications on your own. Always talk to your doctor before starting a different treatment. The alternatives below require a prescription and should be chosen based on your specific health needs.
Citric Acid/Sodium Citrate is a urinary alkalinizer — a medication that makes your urine less acidic. It's available as an oral liquid solution under brand names like Bicitra, Cytra-2, Oracit, and Virtrate.
Doctors prescribe it for:
For a complete overview, see our article on what Citric Acid/Sodium Citrate is and how it's used.
Once you swallow Citric Acid/Sodium Citrate, your body converts the sodium citrate into sodium bicarbonate. This acts as a buffer, neutralizing excess acid in your blood and urine.
By raising the pH of your urine (making it less acidic), the medication helps prevent certain types of kidney stones from forming. Uric acid and cystine stones need acidic urine to crystallize — when the urine is more alkaline, these stones are less likely to develop.

Potassium Citrate is the most common alternative to Citric Acid/Sodium Citrate. It works the same way — by alkalinizing the urine — but uses potassium instead of sodium as the base cation.
Key details:
Why your doctor might choose this: If you have high blood pressure, heart failure, or are on a low-sodium diet, Potassium Citrate may actually be a better choice than Citric Acid/Sodium Citrate. The tablet form is also easier to find at most pharmacies than a liquid solution.
Sodium Bicarbonate (baking soda) is one of the simplest and most affordable alkalinizing agents available. It's available over the counter in tablet form and as a powder.
Key details:
Why your doctor might choose this: Sodium Bicarbonate is the most accessible alternative. It's available at virtually every pharmacy and even grocery stores. However, it's harder to dose precisely than Citric Acid/Sodium Citrate, so your doctor will need to guide you carefully.
Tricitrates is a combination of potassium citrate, sodium citrate, and citric acid in a single oral solution. Think of it as a "combination" version that contains both potassium and sodium.
Key details:
Why your doctor might choose this: If your electrolyte needs call for both potassium and sodium, Tricitrates covers both. It's also a liquid solution like Citric Acid/Sodium Citrate, so the switch may feel more familiar.
Cytra-K is an oral solution similar to Cytra-2 (Citric Acid/Sodium Citrate) but uses potassium citrate instead of sodium citrate as the active alkalinizing ingredient.
Key details:
When you call your doctor's office, here's what to say:
Your doctor will consider your overall health, other medications, kidney function, and electrolyte levels before recommending the best alternative.
Not being able to find your prescribed medication is stressful, but Citric Acid/Sodium Citrate is not your only option. Alternatives like Potassium Citrate, Sodium Bicarbonate, Tricitrates, and Cytra-K can all achieve similar results depending on your medical needs.
