What Is Bayer Cystopurin?

This review for Cystopurin will help inform and advise customers on whether or not to purchase this product. Cystorpurin is designed as a powder that is meant to be mixed with water. It is meant to help treat cystitis, which is inflammation of the bladder, generally caused by a bacterial infection. Cystopurin is sold in the U.K and Canada, but can also be found on websites such as Amazon.com, as well as through the manufacturer’s website.


The active ingredient in Cystopurin is potassium citrate. Cystitis causes painful urination, as well as feeling the need to urinate frequently. This is because the bacteria in the bladder causes the urine to become acidic. Potassium citrate is used to combat the symptoms of cystitis by reducing the acidity. Cystopurin also contains natural cranberry juice extract, and sweeteners aspartame and mannitol. Cystopurin is low in sodium.


Cystopurin has very simple directions. It is meant to be used as a 48-hour treatment and should be taken right after symptoms appear. The sooner it is taken, the more effective it is. Mix one packet of Cystopurin with water. Do this three times a day for two days.

It is also recommended to drink water throughout the day, as this will help bacteria exit the bladder. Avoid soda, caffeine, and alcohol to increase Cystopurin’s success.

Children under the age of 6 should not take Cystopurin.


One box of Cystopurin, which contains six packets, is £5.35 on the manufacturer’s website. This converts to $7.12.

Possible Side Effects

The only reported side effect is increased potassium levels in the blood. However, this is an important side effect to be aware of, as increased potassium levels can cause heart rhythm changes.

However, there are other concerns and conditions that should be considered before deciding to take Cystopurin. If any of these symptoms are present before taking Cystopurin, consult a doctor:

  • Dark, cloudy, or bloody urine
  • Shivers
  • Fever
  • Severe stomach, groin, or back pain
  • Heavy vaginal discharge

Pregnant or nursing women should consult a doctor before taking Cystopurin. Those with kidney or heart disease should also consult a doctor.

Taking Cystopurin with the following medications can increase potassium levels in the blood:

  • ACE inhibitors, such as captopril and enalapril.
  • Angiotensin II receptor antagonist, such as losartan.
  • Potassium-sparing diuretics such as spironolactone, triamterene, and amiloride.
  • Potassium supplements.
  • Potassium-containing salt substitutes.
  • Ciclosporin.
  • Tacrolimus.

Manufacturer’s Commitments

The manufacturer does not provide any guarantees on their websites. However, they encourage users to report any side effects, or quality issues, to Bayer Pic.

Bottom Line

Cystopurin is an extremely simple medication to take, and it has a short treatment plan. It is also a relatively cheap medication to purchase. However, it is not a doctor prescribed medication and there are no guarantees it with help resolve cystitis. There are also many considerations to keep in mind before deciding to take Cystopurin as an increase in potassium levels could lead to potentially harmful side effects. The manufacturer does not advertise any guarantees, indicating that lesser-quality products may not be refunded.
