About Raloxifene Hcl: Raloxifene is used by women to prevent and treat bone loss (osteoporosis) after menopause. Show more ▾

Raloxifene belongs to a class of drugs known as selective estrogen receptor modulators-SERMs. This medication should not be used before menopause. It should not be used to prevent heart disease.

About this data. The prescription history for DR. MARY ELIZABETH HIENAMAN MD is compiled from the Centers for Medicare & Medicaid Services (CMS) Medicare Part D Prescriber Public Use File for calendar year 2023, the most recent federal release. Figures cover prescriptions filled for Medicare Part D beneficiaries only; prescriptions under private insurance, Medicaid, or self-pay plans are not included. Because prescribing decisions are generally consistent across coverage types, this record offers a useful view of the overall Obstetrics & Gynecology prescribing approach at this Houston, TX practice.

Reading the costs. Drug costs are gross amounts paid to pharmacies under Part D, including both plan and beneficiary payments. They are not the price a patient pays at the pharmacy counter. Medications with fewer than 11 claims are excluded from the federal source data, and state comparisons use the average volume among TX prescribers of the same medication. Always confirm current medications and costs directly with the provider and your plan.
