When to End Treatment

While SUPPRELIN® LA is in place, your child must have regular visits with your pediatric endocrinologist. The doctor will perform regular exams and blood tests to check for signs of puberty: height and weight will be measured, and wrist x-rays may be taken to track bone growth. Your healthcare provider will work with you to determine the appropriate time to end treatment with SUPPRELIN LA.

Important Safety Information

  • SUPPRELIN LA should not be used by women who are or may become pregnant, and in patients who are allergic to gonadotropin releasing hormone (GnRH) or GnRH agonist analogs. Safety and effectiveness in children under 2 years of age has not been determined.

  • SUPPRELIN LA, like other GnRH agonists, may cause a temporary increase in the blood levels of specific hormones associated with the onset of puberty (estrogen in girls and testosterone in both sexes) during the first week of treatment. This increase may temporarily worsen puberty symptoms during the first week, additionally, you may see new symptoms appear during this period. Within the 4 weeks of treatment with SUPPRELIN LA, hormonal suppression generally occurs and the physical signs of puberty should decrease.

  • Your doctor should monitor the levels of specific hormones associated with puberty progression, 1 month after starting SUPPRELIN LA and then every 6 months thereafter. Every 6-12 months, height and bone age should be also monitored by your doctor.

  • During the clinical trial testing of SUPPRELIN LA, the most common side effects involved the implant site and included temporary bruising, pain, soreness, redness of the skin and swelling.

Please talk with your doctor for more information or if you have any questions.
