"Every persons body is different, but I have had a HORRIBLE experience with this medicine. I switched from Lo-Estrin 24 FE to Tri-Sprintec because of the dramatic price difference, but immediately switched back after three days of feeling like I was dying. Horrible headaches, extreme nausea, black outs, and I was even randomly losing my vision. Like I said everyone is different, so you won't know until you try, but if your body is accustomed to lower doses of hormones and you switch to something higher, it isn't a good result."
