Research table: Antidepressants and other non-hormone medications for relief of menopausal symptoms

This summary table contains detailed information about research studies. Summary tables are a useful way to look at the science behind many breast cancer guidelines and recommendations. However, to get the most out of the tables, it’s important to understand some key concepts. Learn how to read a research table.

Introduction: Selective serotonin reuptake inhibitors (SSRIs) antidepressants and non-SSRI antidepressants have been shown to decrease the frequency and strength of hot flashes, with few side effects.

SSRI antidepressants include:

  • Citalopram (Celexa)
  • Escitalopram (Lexapro)
  • Fluoxetine (Prozac)
  • Paroxetine (Paxil)
  • Sertraline (Zoloft)

Some SSRIs may interfere with tamoxifen. However, it’s not known if this impacts the effectiveness of tamoxifen treatment for breast cancer [1]. If you’re taking tamoxifen, talk with your health care provider before taking an SSRI.

Non-SSRI antidepressants include:

  • Venlafaxine (Effexor)
  • Desvenlafaxine (Pristiq)

Other non-hormone medications 

Gabapentin (Neurontin), and pregabalin (Lyrica) and clonidine are under study for the relief of hot flashes.

Learn about the strengths and weaknesses of different types of studies.

Study selection criteria: Randomized controlled trials that compared a non-hormone medication to a placebo with at least 100 participants, pooled analyses and meta-analyses. A placebo is an inactive substance sometimes used to have a comparison to a drug in a clinical trial.

Table note: Relative risk above 1 indicates increased risk. Relative risk below 1 indicates decreased risk.
