Important: How To Use This Information
This is a summary and does NOT have all possible information about this product. This information does not assure that this product is safe, effective, or appropriate for you. This information is not individual medical advice and does not substitute for the advice of your health care professional. Always ask your health care professional for complete information about this product and your specific health needs.
This medication is used with other treatments for certain problems with the intestines (ulcerative colitis). Using this medication as an enema allows it to work directly on the affected area as well as throughout the body. It does not cure this problem, but it may relieve pain and decrease the amount of diarrhea and bloody stools caused by swelling (inflammation). Betamethasone is an anti-inflammatory drug (corticosteroid hormone). It works by decreasing the body's natural defense response and decreasing inflammation.
How To Use
Use this drug in the rectum, usually once daily in the evening or as directed by your doctor. Dosage is based on your medical condition and response to treatment.
For best results, use after a bowel movement. Lie on your left side with the left knee bent toward the chest. Gently insert the opening of the enema bag into the rectum. Gently but firmly squeeze the bag so that all of the drug flows into the rectum. Continue lying on your left side for at least 30 minutes. Keep the medicine in your rectum for at least 1 hour and overnight if possible.
Use this medication regularly to get the most benefit from it. To help you remember, use it at the same time each day.
Do not use more of this product, use it more often, or keep using it for longer than prescribed by your doctor. If you have been using this medication for a long time, do not suddenly stop it without your doctor's approval. Some conditions may become worse when this drug is suddenly stopped. Your dose may need to be gradually decreased to reduce symptoms such as extreme tiredness, weakness, weight loss, or nausea.
Tell your doctor if your condition persists or worsens.
