About sodium citrate for cystitis
Tipo de medicamento | An alkalinising agent |
Usado para | Mild urinary tract infections such as cystitis |
Também chamado de | CanesOasis®; Cystitis Relief®; Cystocalm® |
Disponível como | Sachês de pó |
Cistite 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.

Voltar ao conteúdoIf 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.
