Explanation on whether fezolinetant will affect menstruation while taking it

Fezolinetant is a selective neurokinin 3 receptor antagonist, mainly used to relieve moderate to severe vasomotor symptoms in menopausal women, such as hot flashes and night sweats. This drug is not a hormonal drug and does not significantly affect estrogen levels in the body, so it has relatively little interference with women's menstrual cycles. However, in practice, some women may still observe changes in menstruation while taking the drug.

Based on clinical study data, perimenopausal women may experience slight prolongation of their menstrual cycles or changes in menstrual flow when using fezonatant. This is mainly related to the role of neurokinin3 (NK3) receptors in regulating the hypothalamic-pituitary-ovarian axis. Although fizonatant is not a hormonal drug that directly acts on the ovaries or uterus, its effect on the central nervous system may indirectly regulate the secretion of hormones such as luteinizing hormone (LH), thereby having a certain impact on menstruation.

It is worth noting that filazonatant is more commonly used in women who have entered or are close to menopause. These people have already disrupted their menstrual cycles, so it is often difficult to clearly attribute the cycle changes caused by the drug. For women who still have regular menstruation, if they experience delayed or early menstruation or abnormal bleeding while taking it, it is recommended to record the situation and consult a doctor in time to rule out other pathological causes.

Overall, the effects of filazonatant on menstruation are not universal or significant, and most users will not experience significant menstrual irregularities from the drug. If menstrual abnormalities occur during treatment, the patient's age, hormone levels, and past medical history should be considered for evaluation. Medication can be adjusted or further examined if necessary to ensure medication safety and therapeutic effect.
