INSTYLAN is a colorless, transparent, sterile solution based on hyaluronic acid of non-animal origin with physiological pH.

INSTYLAN is a viscoelastic protective agent of the intercellular substance of vesical and urethral urothelium.

Mode of action

Hyaluronic acid is contained in all tissues and is the most significant component of the intercellular matrix and thus constitutes a significant part of the glycosaminoglycans of the urothelium of the bladder and urethra (urinary tract).

INSTYLAN is indicated for restoration of the protective layer of the bladder mucosa after invasive interventions (such as cystoscopy, transurethral resection of the prostate, ureteroscopy, etc.) and in deficiency of a layer of glycosaminoglycans to reduce the clinical manifestations of cystitis of various etiologies, painful urinary bladder syndrome.


  • Recurrent bacterial cystitis.
  • Interstitial cystitis.
  • Painful urinary bladder syndrome.
  • Hemorrhagic cystitis.
  • Radiation cystitis.
  • Chemotherapy-induced cystitis.


  • Hypersensitivity to any of the medical device constituents.
  • Pregnancy and breastfeeding.
  • Age under 18 years.

Target group (population)

Patients over the age of 18 who require relief of clinical manifestations of cystitis of various etiologies and painful urinary bladder syndrome.

Method of use

Prior to use, the bag with the solution should be warmed to body temperature. The solution warmed to body temperature reduces the patient’s discomfort. This procedure should only be carried out using dry heat (for example, heating pad or hot plate). The solution should not be heated in water due to increased risk of contamination. To avoid potential damage to the polymer bag and damage or discomfort to the patient, the solution should not be heated in the microwave.

Before administration of INSTYLAN, the bladder should be emptied.

Strict aseptic rules should be followed during the entire procedure.

INSTYLAN is injected into the bladder cavity by means of a urinary catheter. After administration of the solution, the catheter is removed. The recommended retention time of the solution in the bladder lumen is 30 minutes to 2 hours. Then the bladder should be emptied physiologically.

INSTYLAN is intended for intravesical administration, once weekly. The course is 4 to 12 instillations.
