"i have been taking tri-sprintec for 2 1/2 years.  my period is regular and 5-6 days.  i need to switch because i cannot find tri-sprintec or any other triphasic pill in nicaragua right now.  since i&#039;ve been looking into other pills, i have been reading a lot about side effects and have just realized that i have been experiencing several side effects from tri-sprintec.  contact lens tolerance - i have not been able to wear my contacts for more than two hours for the last 2 1/2 years.  low sex drive.  not chronic but 3 yeast infections in the last two years. one urinary tract infection. i did not have any of these issues before i started taking tri-sprintec."
