Grandpa-Kopfschmerzpulver und Menstruation: Kein wissenschaftlicher Zusammenhang

There is no scientific evidence that “Grandpa Headache Powders” (or any analgesic powder containing aspirin, acetaminophen, caffeine) can stop menstrual periods.

Menstruation is controlled by the hypothalamic-pituitary-ovarian axis. Analgesics may temporarily reduce prostaglandin-mediated cramps and flow heaviness, but they do not halt the cycle. Claims otherwise are anecdotal or confused with hormonal contraception.

If periods stop unexpectedly, consider pregnancy, stress, weight change, PCOS, thyroid, or perimenopause—see a clinician.
