Anastrozole | Compounded Oral Medication
Important Safety Information: Anastrozole | Compounded Oral Medication
Anastrozole is a prescription aromatase inhibitor that helps reduce estrogen levels by blocking the enzyme that converts androgens into estrogen. In men, elevated estrogen can result from testosterone therapy or natural hormone imbalances. By supporting healthy estrogen control, Anastrozole may help reduce unwanted symptoms like water retention, mood changes, and gynecomastia (development of breast tissue). This product is commonly prescribed alongside hormone therapy and should only be taken under medical supervision based on lab results and your provider’s discretion.
This product may be dispensed as either an FDA-approved commercial medication or a compounded formulation prepared by a licensed compounding pharmacy. Compounded medications have not been reviewed by the FDA for safety or efficacy. Review important medication safety information.
