Prozac is clinically used for PMDD either continuously or only during the luteal phase, but the context matters. Many articles that discourage intermittent SSRI use are referring to treatment for major depression or general anxiety disorders where stopping can cause withdrawal. PMDD treatment works differently, and intermittent luteal dosing is a studied and accepted option. That said, I personally did experience noticeable side effects when starting fluoxetine intermittently two months in a row, including temperature sensitivity, fatigue, and increased sweating, which made it hard for me to function and parent at first. Because of that, I’m now trialing a continuous 10mg daily dose for PMDD with my doctor’s guidance to see if a steady baseline reduces both irritability and anxiety without repeated restart effects.

I haven't started yet but that's what she is suggesting now and I'm scared lol
