Treatment of Postmenopausal Symptoms
For initiation and continuation of treatment of postmenopausal symptoms, the lowest effective dose for the shortest duration (see section 4.4) should be used.
Treatment to control menopausal symptoms should be initiated with Premarin 0.3mg. If symptoms are not adequately controlled, higher doses of Premarin may be prescribed. Once treatment is established the lowest effective dose necessary for the relief of symptoms should be used. Patients should be re-evaluated periodically to determine if treatment for symptoms is still necessary.
