Fulvenat 250 mg/5 mL Fulvenat 250 mg/5 mL contains Fulvestrant, a hormonal anti-cancer medicine used to treat hormone receptor-positive breast cancer in postmenopausal women. It helps reduce the influence of estrogen on cancer cells by blocking and lowering the number of estrogen receptors, making it harder for hormone-sensitive tumors to grow. Fulvenat is commonly prescribed for advanced or metastatic breast cancer and may be used alone or in combination with other targeted therapies as part of a long-term treatment plan. The injection should be administered only by a qualified healthcare professional.
