Dextranomer and sodium hyaluronate are natural materials formed into a gel that is similar to certain substances that occur naturally in your body. dextranomer and sodium hyaluronate works by thickening the tissues in your anal canal.

Dextranomer and sodium hyaluronate is injected as an implant into your anal canal to treat fecal incontinence (loss of bowel control) in adults.

Dextranomer and sodium hyaluronate may also be used for purposes not listed in this medication guide.

You should not receive dextranomer and sodium hyaluronate if you have: rectal infection or bleeding, rectal fissure, rectal tumor, rectal malformation, rectal prolapse, an abnormal passageway between the rectum and vagina, stenosis (narrowing) of your anal canal, a rectal or anal implant (other than Solesta), congested blood vessels in the anus or rectum, inflammatory bowel disease, a history of radiation to your pelvic area, or a weak immune system.

A healthcare provider will give you dextranomer and sodium hyaluronate in an outpatient clinic setting. Dextranomer and sodium hyaluronate is given as a set of 4 injections directly into the tissues of your anal canal.

You will be given an enema to clean out your rectum just before dextranomer and sodium hyaluronate is injected.

You will receive the injections while lying on your side. A small tube called an anoscope will be gently inserted just a few inches into your rectum. This will help the doctor determine where to properly place the needle when injecting dextranomer and sodium hyaluronate. You will be made to feel as comfortable as possible while the medicine is injected.

Tell your caregivers if you feel severe pain during the injections.

You will be able to get up after your injections are completed. However, you should remain resting for about 60 minutes before leaving the clinic. Your caregivers will check you for any immediate side effects the injections may cause.

Do not take a hot bath or engage in physical activity during the first 24 hours after your injection procedure.

You may use a stool softener to make your first bowel movement more comfortable after treatment. Do not continue using the stool softener unless your doctor tells you to.
