| How it works | Gabapentin binds to the alpha-2-delta subunit of voltage-gated calcium channels in the central nervous system, which may calm overactive temperature regulation and reduce hot flash frequency. Pregabalin binds the same target but NAMS 2023 does not recommend it for hot flashes. | Excess body fat may contribute to vasomotor symptoms by altering thermoregulation and hormone metabolism. Losing weight through behavioral changes (diet and exercise) may reduce the frequency and severity of hot flashes, particularly for women who are overweight or obese and earlier in the menopause transition. |
