Common side effects of anastrozole include hot flushes, altered mood, joint pain, and nausea.[1][6] Severe side effects include an increased risk of heart disease and osteoporosis.[1] Use during pregnancy may harm the baby.[1] Anastrozole is in the aromatase-inhibiting family of medications.[1] It works by blocking the production of estrogens in the body, and hence has antiestrogenic effects.[1]
