Hello Sienna.How are you?
Neuroleptic antipsychotics are known to cause amenorrhea and dysmenorrhea. This is usually the result of the drugs causing an excess in the secretion of prolactin, a hormone responsible for supporting lactation.
I know that the older antipsychotics (Haldol, Thorazine, Prolixin, Loxitane, etc.) have this as a side effect. Of the newer "atypical" antipsychotics, Risperdal most closely resembles the older drugs, and is most liable to cause amenorrhea. My S.O. went seven months without having her periods while taking Risperdal at dosages above 0.5mg. As for Geodon (ziprasidone), the medical literature generally accepts it as having a reduced liability to cause hyperprolactinemia (high prolactin). However, if my recollection is at all accurate, Geodon blocks dopamine receptors to a significant degree relative to the other atypicals, and nearly equal to Risperdal. For this reason, I would guess it possible for Geodon to mess things up a little.
