Folic acid is one of the B vitamins that when absorbed into its active form is converted to tetrahydrofolate. Folate is an essential cofactor for the biosynthesis of norepinephrine and serotonin. Studies have also noted that folate, with a mechanism like hormone replacement therapy (HRT), can improve hot flashes by interfering with monoamine neurotransmitters called norepinephrine and serotonin .The purpose of the current study is to investigate the role of folic acid administration at two different doses (1 mg/day and 5 mg/day) in the management of hot flashes associated with adjuvant endocrine therapy in patients with breast cancer.
