Urelle® is a combination of five medicines: hyoscyamine, methenamine, methylene blue, phenyl salicylate, and sodium phosphate. It is used to relieve discomfort, swelling, pain, frequent urge to urinate, and cramps or spasms of the urinary tract caused by an infection or a diagnostic procedure.

Hyoscyamine is an antispasmodic drug, which relieves muscle cramps or spasms. Methenamine and methylene blue are antiseptic drugs, which help clear a urinary tract infection. Phenyl salicylate is a pain reliever. Sodium phosphate makes the urine more acidic, which helps methenamine work better.

Hyoscyamine, methenamine, methylene blue, phenyl salicylate, and sodium phosphate is available only with your doctor's prescription.

Skyla contains levonorgestrel, a female hormone that can cause changes in your cervical mucus and uterine lining, making it harder for sperm to reach the uterus and harder for a fertilized egg to attach to the uterus.

Skyla intrauterine device (IUD) is a small, flexible plastic T-shaped device. This device is placed in the uterus where it slowly releases the hormone to prevent pregnancy for 3 years. (Other types of levonorgestrel intrauterine systems release different amounts of hormone and are used for different lengths of time.)

Skyla can be used whether you have had children or not. It should not be used during pregnancy.

Levonorgestrel is a progestin hormone and does not contain estrogen. The Skyla IUD releases levonorgestrel in the uterus, but only small amounts of the hormone reach the bloodstream. Skyla should not be used as emergency birth control.
