If symptoms do not improve within two days, or if they return within two weeks, see your doctor.
About sodium citrate for cystitis
Tipo de medicamento | An alkalinising agent |
Usado para | Mild urinary tract infections such as cystitis |
También llamado | CanesOasis®; Cystitis Relief®; Cystocalm® |
Disponible como | Sachets of powder |
Cystitis means inflammation of the bladder. It is usually caused by a urine infection. Typical symptoms are pain when you pass urine and passing urine more frequently. Your urine may also become cloudy and smelly. It is particularly common in women. A short course of antibiotics may be prescribed for you, although mild cases often improve on their own without the need for any treatment as your own immune system can often clear the infection.
Preparations containing sodium citrate are sometimes recommended for the treatment of mild cystitis. They can help to relieve the discomfort, although there is no strong evidence of benefit. They work by making the urine less acidic. They can be bought without a prescription at pharmacies and other retail outlets.
Nota: if you are pregnant, male or have a medical condition, you should always see a doctor if you think you have cystitis because you may need to be treated with antibiotics.
Before taking sodium citrate for cystitis
To make sure that this is the right treatment for you, before you start taking sodium citrate it is important that you speak with a doctor or pharmacist:
Si estás embarazada.
Si tienes un problema con el funcionamiento de tus riñones.
If you have a heart condition, high blood pressure, diabetes or any other serious medical condition.
If you are on a low sodium diet.
Si está tomando o usando otros medicamentos. Esto incluye cualquier medicamento que esté tomando y que esté disponible para comprar sin receta, así como medicamentos herbales y complementarios.
Si alguna vez has tenido una reacción alérgica a un medicamento.
How to take sodium citrate
Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about the sachets you have been given and how to take them.
Follow the dosage instructions on the label. It is usually recommended to take one sachet, three times a day for two days. Empty the contents of the sachet into a glassful of water and stir it well before drinking.
Obteniendo el máximo de tu tratamiento
If your symptoms do not improve within two days of taking sodium citrate, or if you develop a high temperature, you should contact your doctor.
You might find it helpful to ask your pharmacist to recommend a suitable painkiller. Paracetamol or ibuprofen can also help to ease the pain and discomfort of cystitis.
Although it has been said that drinking lots of water may be helpful, there is little evidence for this. Some doctors feel that it does not help and drinking lots may just cause more painful toilet trips. You should follow the directions on the label for taking the sachets mixed into water but other than this, drinking normal amounts of fluid is often sufficient.
If your symptoms recur within two weeks, you should make an appointment to see your doctor for further advice.
Can this preparation cause problems?
Recommended doses of sodium citrate are unlikely to cause any side-effects other than making you want to pass a little more urine than normal. If you experience any other symptoms which you think may be due to the medicine, speak with your doctor or pharmacist for further advice.

Preguntas frecuentes
Can men take sodium citrate for cystitis?
If you are male and think you have cystitis, you should always see a doctor. This is because men may need antibiotics, and therefore preparations like sodium citrate sachets aren't suitable without prior medical assessment.
Does sodium citrate treat or cure a UTI?
Sodium citrate is used to relieve the discomfort associated with mild cystitis by making the urine less acidic. There is no strong evidence that it treats or cures the underlying infection itself. Mild cases of cystitis can sometimes improve on their own as your immune system clears the infection.
How long does it take for sodium citrate to work?
The article does not specify an exact timeframe for when sodium citrate starts to work. However, it recommends contacting your doctor if your symptoms do not improve within two days of taking it, which suggests relief should be experienced within this period for it to be effective.
Can I take other medicines with sodium citrate?
You should speak with a doctor or pharmacist if you are taking any other medicines, including those bought without a prescription, as well as herbal and complementary medicines. This is important to ensure sodium citrate is the right treatment for you and to avoid potential interactions.
What should I do if my cystitis symptoms come back after taking sodium citrate?
If your symptoms recur within two weeks after finishing a course of sodium citrate, you should make an appointment to see your doctor for further advice. This indicates that a medical assessment would be necessary.
