Is gynera ok to take back to back without stop for endometriosis? i was taking yasmin/yaz but had allergies. thanks.

Yes: Any formulation of contraceptive pills is fine to use 'continuously' for endometriosis treatment. The progestin hormone acts ago help 'shrink' endometriosis lesions, and helps to control the symptoms of endo. The differences in how an individual reacts to(or feels on) any given pill formulation usually reflects effects of the dift progestin components and estrogen content.
