The same thing has happened to me. I've been off birth control nearly three months now and my underarm sweating has gotten way worse. Which is disappointing, considering it was a concern BEFORE going off the pill.
Does Birth Control Pills Help Prevent Armpit Sweating? I Recently Stopped Taking And Started Sweating Under My Arms Very Badly! I Have Also Gained Some Weight.
Birth control pills don't prevent armpit sweating. However, the hormonal changes when starting or stopping the pill could cause some differences in your body, especially weight gain. Give it a while to see if it stops until then try a prescription strength deodorant. If it continues, speak with a doctor... There is help out there.
Now the weight gain is truthful due to using birth control pills but not the armpit sweating try switching deodorant good luck not trying to be funny if your side effects say causes armpit sweating then you need to switch pills lol good luck
