Pituitary Apoplexy and Tumors
- Very rare cases of pituitary tumors have been reported.
- Reduction in glucose tolerance, manifesting as diabetes or loss of glycemic control in those with preexisting diabetes, has been reported during treatment with GnRH agonists, including Zoladex.

PATIENT COUNSELING INFORMATION
- The use of GnRH agonists may cause a reduction in bone mineral density. In men, data suggest the use of a bisphosphonate in combination with an GnRH agonist may reduce bone mineral loss.
- Patients should be informed that diabetes, or loss of glycemic control in patients with pre-existing diabetes, has been reported during treatment with GnRH agonists, including Zoladex. Consideration should therefore be given to monitoring blood glucose in patients receiving Zoladex.
- The use of GnRH agonists in women may cause a reduction in bone mineral density. In women, current available data suggest that recovery of bone loss occurs on cessation of therapy in the majority of patients.
