  • Is clinically proven. In a number of important measurements of a drug's effectiveness in treating metastatic ER+ breast cancer in postmenopausal women, Fareston worked just as well as tamoxifen1-4
  • May provide the continued benefits of endocrine therapy. Fareston may offer you the continued benefits of endocrine therapy if you cannot tolerate or are otherwise unable to take other endocrine therapies1-6
  • Fareston may be an effective alternative for patients who have stopped taking other endocrine therapies because of joint pain1-4,6
  • Is available and accessible. Fareston is widely available on commercial and Medicare Part D formularies and is covered by most commercial and Medicare insurance plans.7 In addition, comprehensive support for patients who have been prescribed Fareston can be found through Patient Rx Solutions, including copay savings of up to $150 a month (after paying the first $20) on your out-of-pocket prescription costs**

Important Safety Information and Boxed Warning

 

Indication

Fareston® (toremifene citrate) 60 mg Tablets is an estrogen agonist/antagonist indicated for the treatment of metastatic breast cancer in postmenopausal women with estrogen-receptor-positive or unknown tumors.

WARNING: QT PROLONGATION

Fareston has been shown to prolong the QTc interval in a dose- and concentration-related manner. Prolongation of the QT interval can result in a type of ventricular tachycardia called Torsade de pointes, which may result in syncope, seizure, and/or death. Toremifene should not be prescribed to patients with congenital/acquired QT prolongation, uncorrected hypokalemia, or uncorrected hypomagnesemia. Drugs known to prolong the QT interval and strong CYP3A4 inhibitors should be avoided.

Contraindications
  • Fareston is contraindicated in patients with known hypersensitivity to the drug, and in patients with congenital/acquired QT prolongation (long QT syndrome), uncorrected hypokalemia, or uncorrected hypomagnesemia.
Warnings and Precautions
  • Fareston has been shown to prolong the QT interval. Caution should be exercised in patients with congestive heart failure, hepatic impairment and electrolyte abnormalities. In patients at increased risk, ECGs should be obtained at baseline and as clinically indicated.
  • Hypercalcemia and tumor flare have been reported during the first weeks of treatment with Fareston in some breast cancer patients with bone metastases. If hypercalcemia is severe, Fareston treatment should be discontinued.
  • Patients with preexisting endometrial hyperplasia should not be given long-term Fareston treatment, and patients at high risk for endometrial cancer should be closely monitored.
  • Patients with a history of thromboembolic diseases should not be treated with Fareston.
  • Leukocyte and platelet counts should be monitored when using Fareston in patients with leukopenia and thrombocytopenia.
  • Fareston can cause fetal harm when administered to a pregnant woman.
  • Fareston is only indicated for postmenopausal women. However, premenopausal women prescribed Fareston should use effective nonhormonal contraception and should be apprised of the potential hazard to the fetus should pregnancy occur.
Adverse Reactions
  • The most common adverse reactions are hot flashes, sweating, nausea, and vaginal discharge.
