• Advanced breast cancer
• Hypersensitivity to drug or its components
• Cerebrovascular or thromboembolic disease
• Hepatic dysfunction or disease
• Breast or genital cancer
• Undiagnosed vaginal bleeding
• Known or suspected pregnancy
Use cautiously in:
• seizure disorder, renal or cardiovascular disease, asthma, diabetes mellitus, depression, migraine
• history of hepatic disease.
• Before starting therapy, obtain thorough history and physical examination, with emphasis on breast and pelvic organs. Also obtain Pap smear, and repeat annually during therapy.
• With contraceptive use, rule out pregnancy before first dose and when more than 14 weeks have passed since previous dose.
• For I.M. injection, inject deep into gluteal, deltoid, or anterior thigh muscle. Rotate injection sites.
• Be aware that when drug is used to prevent estrogen-related endometrial changes in postmenopausal women, lowest dosage should be used for shortest time, because treatment exceeding 1 year correlates with cancer. (Some combination products have 0.3 mg estrogen/1.5 mg progesterone or 0.45 mg estrogen/1.5 mg progesterone.)

Acne, dysmenorrhoea, birth defects if taken during pregnancy, headache, breast tenderness, increased facial hair, decreased scalp hair, insomnia, abdominal pain/discomfort, dizziness, asthenia (weakness or fatigue), and weight changes.
