I think this is one of the most overlooked factors in medication treatments for ADHD and related disorders. We often think of drug-drug, drug-food, or drug-environment interactions, but often neglect to consider important drug-hormonal interactions. Unfortunately, there isn't a whole lot of research on these effects, at least at the moment.
Estrogen and progesterone fluctuations seem to have a big impact on medications, especially amphetamine or amphetamine-like stimulants.
In general, higher estrogen levels seem to increase the effects of amphetamines, while high progesterone levels seem to counteract this effect and decrease the effects of these stimulants.
During the follicular phase (pre-ovulation), a higher estrogen to progesterone ratio often results in more pronounced effects of stimulants such as amphetamines (a more pronounced effect or "high" can typically be seen during this stage), while during the luteal (post-ovulation) phase of the menstrual cycle, where progesterone levels are typically higher, these "euphoric" feelings associated with amphetamine-based ADHD treatments typically subside.
This could indicate that for women with ADHD who are taking stimulant meds (especially of the Adderall, Dexedrine and Vyvanse varieties of amphetamine-based treatments) may benefit from slightly higher doses of drugs during the luteal phase of the menstrual cycle (when progesterone is higher relative to estrogen), while requiring slightly lower levels of medication to get the same effects during the relatively high estrogen boosts of the follicular phase.
