I have read so many reviews of women switching to different brands of birth control and experiencing hormonal changes and awful side effects. If the 'active' ingredients are the same, then why are the supposed 'inactive' ingredients allowed to cause hormonal changes? Doesn't that by definition make them active ingredients? This seems so unacceptable to me. I finally experienced this for the first time myself and it kind of blows my mind. Weight gain, breast tenderness, depression, joint pain. I'm half way through my 3rd month on Blisovi, trying to tough it out after being side-effect-free on Gildess. I mean this is seriously unacceptable. These kind of hormonal changes can initiate a flare in people with RA. How is this allowed???
