"I was previously on Tri-Sprintec for years, when my pharmacy started carrying Tri-Previfem. I switched thinking it would affect me the same. However, I started getting headaches often, feeling weak, my face broke out, and I had spotting. I know that these effects may come when switching brands, but when I switched from Ortho TriCyclen Lo to its generic, then back to brand, then to Tri-Sprintec I have never had any problems. I am a pharmacy technician and I have had several customers that have had trouble when switching to Previfem or Tri-Previfem. I will be switching back to Tri-Sprintec once the pharmacy special orders it."
