For Healthcare Professionals

Applies to leuprolide: intramuscular kit, intramuscular powder for injection, intramuscular powder for injection extended release, subcutaneous implant, subcutaneous kit, subcutaneous powder for injection extended release, subcutaneous solution

Endocrine

Endocrine side effects of leuprolide (the active ingredient contained in Lupron Depot-Gyn) have included hot flashes (56% to 91%), gynecomastia (7%), breast changes (7%), breast enlargement (7%), breast tenderness (7% to 14%), decrease in testicular size, diabetes, and impotence. In addition, rare cases of pituitary apoplexy have been reported after the use of gonadotropin-releasing hormone agents.

Endocrine side effects occur in the majority of patients treated with leuprolide and are due to drug-induced hypoestrogenism and hypoandrogenism.

Pituitary apoplexy is a clinical syndrome secondary to infarction of the pituitary gland. In a majority of the cases reported, a pituitary adenoma was diagnosed. A majority of pituitary apoplexy cases occurred within two weeks of the first dose, and some occurred within the first hour. In those cases, pituitary apoplexy presented as sudden headache, vomiting, visual changes, ophthalmoplegia, altered mental status, and sometimes cardiovascular collapse. Immediate medical attention has been required.

Psychiatric

Psychiatric side effects have included depression and emotional lability (up to 45%), insomnia (2% to 7%), anxiety, nervousness, decreased libido (both males and females), increased libido (females), and short-term memory loss.

Nervous system

Nervous system side effects have included headache (7% to 39%), dizziness (5%), blurred vision, lethargy, paresthesias, numbness, peripheral neuropathy, spinal fracture, convulsions, transient ischemic attack, and paralysis. A case of atypical absence seizures induced by leuprolide (the active ingredient contained in Lupron Depot-Gyn) acetate has also been reported.

Genitourinary

A number of cases of vaginal hemorrhage are reported in the literature. The presence of submucous leiomyomatas may be responsible for these events. These patients typically required emergency surgery and blood transfusions.

Massive ascites developed in one patient 3 weeks after receiving a 3.75 mg leuprolide (the active ingredient contained in Lupron Depot-Gyn) depot injection for the treatment of leiomyomata uteri. Upon surgical resection, the uterine myomas were noted to be seeping large amounts of serous fluid.

Genitourinary side effects have included vaginal dryness (37%), urinary frequency, hematuria, ovarian hyperstimulation, testicular soreness/pain, breast soreness/tenderness, testicular atrophy, erectile dysfunction, penile disorder, reduced penis size and vaginal hemorrhage.

Cardiovascular

Cardiovascular side effects have included ECG changes (19%), ischemia (19%), peripheral edema (12%), hypertension, hypotension, murmur, phlebitis, venous and arterial thromboembolism, deep vein thrombosis, stroke, sudden cardiac death, arrhythmias, angina, pulmonary edema, pulmonary embolism, and myocardial infarction.

Gastrointestinal

Gastrointestinal side effects have included constipation (7%), anorexia (3% to 6%), nausea and vomiting (5%), weight loss, flatulence, dyspepsia, and weight gain.

An initial increase in testosterone levels may occur during the first 2 weeks of therapy with leuprolide (the active ingredient contained in Lupron Depot-Gyn) An increase in bone pain, as well as worsening of other signs and symptoms of advanced prostate cancer, may be noted during this time period.

Hypoestrogenism induced by leuprolide may result in small losses in bone density. Prolonged use of leuprolide in females may increase the risk of osteoporosis.

Musculoskeletal side effects have included increased bone pain in patients with advanced prostate cancer, myalgias, arthralgias, muscle atrophy, limb pain, lower bone density scores, and tenosynovitis-like symptoms. A case of polymyositis and a case of noninflammatory myopathy have also been reported.

Hypersensitivity

A case of anaphylaxis after a single intramuscular injection of leuprolide (the active ingredient contained in Lupron Depot-Gyn) depot is reported in the literature. On two occasions, 24 hours and 6 weeks after injection, the patient required emergency airway management. The patient continued to require regular doses of antihistamines and intermittent epinephrine injections up to 14 weeks after leuprolide administration.
