    • What is this medication and its most common uses?

      Menostar is a medicine that contains an estrogen hormone. Menostar is used after menopause to prevent osteoporosis (thin, weak bones). Menostar is available as a patch.

    • What should I know when beginning and continuing on this medication?

      How does this medication work?

      Menopausal women have lower levels of the hormone estrogen in their bodies, resulting in bone loss. Menostar provides estrogen to prevent further bone breakdown.

      What are the beneficial effects of this medication and when should I begin to have results?

      What: Menostar has been shown to increase bone density, thereby helping to prevent osteoporosis.

      When: Everyone responds differently to treatment, so try to be patient and follow your healthcare provider's directions. It is important that you use Menostar exactly as your healthcare provider has prescribed.

      How do I know it is working?

      Your healthcare provider may order tests regularly and ask you questions from time to time to check how well this medication is working.

    • What are the possible side effects of this medication?

      The following is not a full list of side effects. Side effects cannot be anticipated. If any develop or change in intensity, tell your healthcare provider as soon as possible. Only your healthcare provider can determine if it is safe for you to continue taking this medication.

      Using estrogen-only medicines such as Menostar may increase your chance of developing endometrial cancer (cancer of the uterus).

      Less common side effects may include:

      Vision problems, with symptoms such as double vision, bulging eyes, or sudden new severe headaches.

      Women: Apply 1 patch to your skin once a week.

    • How should I take this medication?

      Use Menostar exactly as prescribed by your healthcare provider. Do not use it more often or stop using it without first talking to your healthcare provider.
