Medication details


Cystopurin 3g Granules is a non-prescription medication used to alleviate the discomfort and symptoms associated with cystitis, a common urinary tract infection (UTI) that affects many people, primarily women. The active ingredient in Cystopurin is potassium citrate, which helps relieve the burning sensation and frequent urination that often accompany cystitis.

Cystitis is typically caused by the inflammation of the bladder lining due to bacterial infection. Cystopurin works by reducing the acidity of the urine, which can help alleviate the burning sensation and pain during urination.


Using Cystopurin 3g Granules is straightforward, but it's essential to follow the instructions carefully:
Dosage: Empty the contents of one sachet (3g) into a glass of cold water and stir until the granules dissolve completely. It's important to note that the granules should be dissolved in a glass of water, not swallowed directly.
Frequency: Adults and children over 6 years old can take one sachet three times a day until symptoms improve.
Duration: Continue using Cystopurin as directed until your symptoms are relieved. This typically takes a few days.
Hydration: Drinking plenty of water is recommended during treatment to help flush out the infection and support the effectiveness of Cystopurin.
Consult a Healthcare Professional: If your symptoms persist or worsen despite taking Cystopurin, consult a healthcare professional for further evaluation.


Cystopurin 3g Granules contain the following active ingredient:
Potassium Citrate (3g): Potassium citrate is an alkalinizing agent that helps reduce the acidity of the urine. By doing so, it can alleviate the discomfort associated with cystitis.
The product also includes inactive ingredients such as flavorings, sweeteners, and fillers. These additives may vary depending on the specific formulation, so always refer to the product packaging or consult a healthcare professional for precise ingredient information.

Side Effects

Cystopurin 3g Granules are generally well-tolerated, but, like all medications, it can cause side effects in some individuals. Common side effects may include:
Nausea: Some people may experience mild nausea when taking Cystopurin.
Vomiting: In rare cases, individuals may experience vomiting as a side effect.
Upset Stomach: Gastrointestinal discomfort, such as an upset stomach, can occur.
Allergic Reactions: Although uncommon, some people may have allergic reactions to the ingredients. If you experience symptoms such as rash, swelling, or difficulty breathing, seek immediate medical attention.
Diarrhea: Diarrhea is another potential side effect, although it is rare.
It's important to note that the above list is not exhaustive, and individual responses to the medication may vary. If you experience any side effects or reactions that concern you, consult a healthcare professional.


Before using Cystopurin 3g Granules, consider the following important warnings:
Consult a Healthcare Professional: Always consult with a healthcare professional before using this medication, especially if you are pregnant, nursing, or have underlying medical conditions. They can provide personalized guidance and ensure the product is safe and appropriate for your situation.
Children Under 6: Cystopurin is not recommended for children under 6 years of age.
Hydration: Ensure you maintain adequate hydration during treatment by drinking plenty of water. This supports the flushing of bacteria from the urinary tract.
Avoid in Severe Kidney Disease: If you have severe kidney disease, consult a healthcare professional before using Cystopurin, as it may affect potassium levels in your body.
Interactions: Inform your healthcare provider of any other medications, supplements, or medical conditions you have to avoid potential interactions with Cystopurin.
