Important Safety Information about FASLODEX

Prescription FASLODEX is only for postmenopausal women. Do not take FASLODEX if you are pregnant and do not become pregnant while taking FASLODEX because it may harm your unborn child. (See WARNINGS and CONTRAINDICATIONS sections of full Prescribing Information.)

Because FASLODEX is administered intramuscularly, it should not be used in patients with certain blood disorders or in patients receiving anticoagulants (sometimes called blood thinners, for example, warfarin).

In clinical studies, the most commonly reported side effects were nausea, vomiting, constipation, diarrhea, abdominal pain, headache, back pain, hot flashes, sore throat, and injection site reactions with mild, transient pain and inflammation.

Please see full Prescribing Information. For more information, see your doctor.
