This medication is used to treat a certain bladder condition (interstitial cystitis). Dimethyl sulfoxide is also known as DMSO. It is believed to reduce swelling and pain due to interstitial cystitis and may improve blood supply to the treated area.
This medication is placed into the bladder, usually through a tube (catheter device). The medication is kept in the bladder for at least 15 minutes or as directed by your doctor. After this time, urinate to remove the drug from the bladder.
This treatment is usually repeated every two weeks until relief of symptoms occurs. Follow your doctor's instructions carefully.
This medication is not meant to be given in any other way such as injection into a vein, muscle, or joint. Also, DMSO should not be placed into the bladder at the same time as any other medications.
Inform your doctor if your condition persists or worsens.
