Fluoroestradiol f 18 drug interactions

Quoted from the “Drug Interactions” section of the FDA-approved label. Tell your pharmacist about every medicine, vitamin and herbal product you take.

Drugs that bind to the estrogen receptor (ER) may compete with the binding of fluoroestradiol F 18 and may reduce the detection of ER-positive lesions with CERIANNA. Before administering CERIANNA, discontinue drugs that bind to the ER, such as SERMs and SERDs, for at least 5 biological half-lives (e.g., elacestrant for 11 days, tamoxifen for 8 weeks, and fulvestrant for 28 weeks) [see Dosage and Administration (2.3)].

Only authorized persons qualified by training and experience should receive, use, and administer CERIANNA. Handle CERIANNA with appropriate safety measures to minimize radiation exposure during administration [see Warnings and Precautions (5.2)]. Use waterproof gloves and effective radiation shielding, including syringe shields, when preparing and handling CERIANNA. 2.2 Recommended Dosage and Administration Instructions Recommended Dosage The recommended amount of radioactivity to be administered for PET imaging is 222 MBq (6 mCi), with a range of 111 MBq to 222 MBq (3 mCi to 6 mCi), administered as a single intravenous injection of 10 mL or less over 1 to 2 minutes. Preparation and Administration For patient preparation instructions, see Dosage and Administration 2.3. Use aseptic technique and radiation shielding when withdrawing and administering CERIANNA. Visually inspect the radiopharmaceutical solution. Do not use if it contains particulate matter or if it is cloudy or discolored (CERIANNA is a clear, colorless solution). CERIANNA may be diluted with 0.9% Sodium Chloride Injection, USP. Assay the dose in a suitable dose calibrator prior to administration. Post-Administration Instructions Follow the CERIANNA injection with an intravenous flush of 0.9% Sodium Chloride injection, USP. Dispose of any unused CERIANNA in compliance with applicable regulations. 2.3 Patient Preparation Assessment for Drug Interactions Before administering CERIANNA, discontinue drugs that bind to ER (e.g., selective estrogen receptor modulators (SERMs) and selective estrogen receptor down-regulators (SERDs)) [see Drug Interactions (7)]. Patient Hydration and Voiding Instruct patients to drink water to ensure adequate hydration prior to administration of CERIANNA and to continue drinking and voiding frequently during the first hours following administration to reduce radiation exposure. Pregnancy Status Assessment of pregnancy status is recommended in females of reproductive potential before administering CERIANNA. 2.4 Image Acquisition Position the patient supine with arms above the head, if possible. The recommended start time for image acquisition is 80 minutes after the intravenous administration of CERIANNA. Scan duration adapted from the range of 20 minutes to 30 minutes and imaging start times adapted within the range of 20 minutes to 80 minutes may be customized according to the equipment used and patient and tumor characteristics for optimal image quality. 2.5 Image Interpretation Uptake of fluoroestradiol F 18 depends on ER density and function in tumors and physiologic tissue, including in liver, ovary, and uterus.

No animal reproduction studies using fluoroestradiol F 18 have been conducted to evaluate its effect on female reproduction and embryo-fetal development. The estimated background risk of major birth defects and miscarriage for the indicated populations is unknown. All pregnancies have a background risk of birth defects, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.
