The side effects of oophorectomy may be alleviated by medicines other than hormonal replacement. Non-hormonal biphosphonates (such as Fosamax and Actonel) increase bone strength and are available as once-a-week pills. Low-dose selective serotonin reuptake inhibitors (such as Paxil and Prozac) alleviate vasomotor menopausal symptoms, i.e. "hot flashes".[41]
