Active ingredient: Fluphenazine

Fluphenazine, like other typical antipsychotics, can lead to hyperprolactinemia by blocking dopamine receptors in the hypothalamus, which reduces the inhibitory effect of dopamine on prolactin secretion. Elevated prolactin levels can disrupt the normal regulation of reproductive hormones, leading to menstrual irregularities, such as amenorrhea (absence of periods) or oligomenorrhea (infrequent periods) which may be reflected on fertility tracking charts. These charts could show prolonged cycles, an absence of ovulation (indicated by a lack of typical cervical mucus patterns or temperature shifts), or irregular bleeding. Such disruptions can make it difficult to track fertile days, highlighting the importance of monitoring reproductive health when using antipsychotics.
