FASLODEX side effects

During your treatment with FASLODEX, you may experience side effects. If you are concerned about any symptoms you may be experiencing, you should contact your doctor's office right away.

  • In a clinical trial, commonly reported side effects seen with FASLODEX were injection site pain, nausea, muscle, joint, and bone pain.
    • In this trial, 0.6% of patients receiving FASLODEX 500 mg and 0.8% of patients receiving FASLODEX 250 mg withdrew from treatment due to side effects
  • Because FASLODEX is metabolized, or broken down, primarily in the liver, a monthly dose of 250 mg is recommended for patients with moderate liver problems
    • FASLODEX was not studied in patients with severe liver problems
  • Because FASLODEX is administered directly into the muscle, you should tell your doctor if you have a blood disorder or are on anticoagulants (sometimes called blood thinners)
