title: Nonhormonal alternatives for the treatment of hot flashes.
abstract: OBJECTIVE
  To review the literature on clonidine, venlafaxine, selective serotonin reuptake inhibitors, and gabapentin for the treatment of hot flashes.
  
  
  METHODS
  A MEDLINE search (January 1966-July 2003) was conducted to identify English-language literature available on the treatment of hot flashes that focused on clonidine, venlafaxine, selective serotonin reuptake inhibitors, and gabapentin. These articles, relevant abstracts, and additional references listed in articles were used to collect pertinent data.
  
  
  METHODS
  All controlled and uncontrolled trials were reviewed.
  
  
  RESULTS
  In women unable or unwilling to take hormonal therapies, several nonhormonal alternatives have been evaluated in small controlled and uncontrolled trials. Oral and transdermal formulations of clonidine are moderately effective in reducing hot flashes. Results of studies evaluating venlafaxine, paroxetine, and gabapentin suggest greater reductions in hot-flash frequency and severity compared with those of clonidine. Fluoxetine appears to display a modest benefit compared with paroxetine, although no comparative trials have been conducted. Most women studied in these trials had a history of breast cancer, and many were taking concurrent tamoxifen. All of these agents were fairly well tolerated.
  
  
  CONCLUSIONS
  Clonidine, venlafaxine, paroxetine, fluoxetine, and gabapentin are nonhormonal agents that have demonstrated efficacy in small controlled and uncontrolled trials in reducing hot flashes and should be considered in patients unwilling or unable to take hormonal therapies.
