Some women are using antihistamines and acid reflux medications to manage premenstrual symptoms. Histamine levels fluctuate throughout the menstrual cycle, and some research indicates a connection between histamine and hormonal changes.

Anyone considering this approach should consult with a healthcare provider before taking medications not prescribed for this purpose.
