About

The goal of this study is to further evaluate the effect of magnesium on the symptoms of menopause, specifically vasomotor symptoms (VMS) in breast cancer patients and/or women at an elevated risk of breast cancer.

Full description

Hot flashes are one of the most common symptoms that are experienced in women during perimenopause, menopause, and as a result of treatment of cancer such as breast cancer. Hot flashes, also known as vasomotor symptoms (VMS) may decrease a woman's quality of life due to discomfort, disruption of daily life, interruption of sleep, and worsening of depression. Previously, estrogen-based therapy was the primary treatment choice for VMS. However, in recent years, this has been considered less favorable due to the increased risk of breast cancer associated with estrogen-based therapy.

While medications such as certain antidepressants, gabapentin and clonidine are available as non-hormonal treatment options, they appear to be less effective in comparison to estrogen therapy with reported adverse effects.

Magnesium supplementation has been found to have very promising results in alleviating VMS in patients with a history of breast cancer. The goal of this study is to further investigate the effects of administering magnesium supplementation in reducing the effects of hot flashes in this targeted population. Our aim is to create a controlled trial using different dosages of magnesium glycinate in the management of hot flashes. Participants will be asked to complete surveys for data collection and analysis.

40 participants in 2 patient groups, including a placebo group

400mg Magnesium Glycinate BID Arm
Experimental group
Description:
Prescription for an 8 week supply (+/- 4 days) of Magnesium Glycinate will be sent to the pharmacy for patient pick up. Study Coordinator will then dispense study diaries (Supplementation Diary and Hot Flash Diary) with instructions on how to complete for the eight week study duration. Study Coordinator will discuss upcoming phone calls on Weeks 2-8 to complete the MDASI by phone and the best times to do so with the patient. Coordinator will schedule a return visit with the Patient approximately 9 weeks after the start of the study for follow-up. At follow-up, Coordinator will retrieve Patient Diaries (Hot Flash Diary and Medication Diary), perform supplement reconciliation, and exit Patient from the study.
