Can I stop taking fezolinetant once I take it?

Fezolinetant, as an NK3 receptor antagonist, works by regulating the signaling pathway of the hypothalamic temperature control center to relieve vasomotor symptoms in menopausal women, such as hot flashes and night sweats. Unlike traditional hormonal therapy, filazonatant does not relieve symptoms by directly changing sex hormone levels, so its efficacy mainly relies on sustained receptor antagonism.

In clinical application, if the patient stops taking the drug, the drug's inhibitory effect onNK3 receptors will gradually disappear, and vasomotor symptoms may reappear within days to weeks. Therefore, Fezonatant is not a "one-time cure", but a maintenance treatment. Doctors will decide whether to continue taking the medication, adjust the dose, or use it intermittently based on the severity of symptoms and the patient's life needs. For patients with mild symptoms and little impact on their lives, they can try to stop taking the drug for a short period of time under the guidance of a physician. For patients whose symptoms significantly affect their sleep or daily life, it is recommended to continue using it to maintain the efficacy.

In addition, stopping the drug will not cause dependence or withdrawal reactions, but symptoms may rebound, which is closely related to the mechanism of action of the drug. Clinical experience has shown that the frequency of hot flashes and night sweats returns to pre-discontinuation levels in some patients after discontinuation of fezonatant, so long-term maintenance strategies often need to be considered in treatment plans. Doctors will provide individualized medication plans based on factors such as the patient's age, hormone levels, cardiovascular risk, and lifestyle habits to ensure sustained efficacy and controllable safety.

Overall, filazonatant is a highly selective targeted drug for the relief of moderate to severe vasomotor symptoms. Although its efficacy depends on continued medication, it is not impossible to discontinue the medication. It is a common phenomenon that symptoms may recur after discontinuing medication. Patients should evaluate medication strategies under the guidance of a doctor to achieve safe and long-term symptom management.
