About potassium citrate
Tipo de medicamento | An alkalinising agent |
Usado para | Mild urinary tract infections such as cystitis |
También llamado | Cystopurin®, Effercitrate® |
Disponible como | Sachets of powder, effervescent tablets, and oral mixture |
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.
Potassium citrate is a product that is sometimes recommended for the treatment of mild cystitis. It may help to relieve the discomfort, although there is no strong evidence of its benefit. It works by making the urine less acidic. It 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 consult a doctor if you think you have cystitis because you may need to be treated with antibiotics. Men are advised to drink at least one litre of water and seek medical attention if symptoms last longer than three hours

Obteniendo el máximo de tu tratamiento
Volver al contenidoIf your symptoms do not improve within two days of taking potassium 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 your potassium citrate preparation with water; however, other than this, drinking normal amounts of fluid is often sufficient.
If your symptoms recur within two weeks, you should make an appointment with your doctor for further advice.
