[|Human|] I have been taking Tri-Sprintec for years now, but about 6 months ago I stopped taking it. I have a prescription...I had unprotected sex and would like to use a method of plan b. Can I do this using the birth control pills I have? I heard if I take a certain amount of them that will work. I am 23, 5 5 and weigh 140 lbs.
[|AI|]  Hi, Welcome to Chat Doctor. I am Chat Doctor. I will be answering your concerns. Plan B pill is more effective as emergency contraception than birth control pills used as emergency contraception. So it is better to use Plan B. Yes it is true that some birth control pills can be used as emergency contraception. Any birth control pill that contains ethanol estradiol and Levonorgestral can be used as emergency contraception (e.g. LO/Oral, Less, Later etc.). The dose is 100 mcg ethanol estradiols and 0.5 mg of levonorgestrel taken as soon as possible after unprotected sex and repeated after 12 hrs. Tri-sprintec contains Ethanol estradiol and Norgestimate. There is no evidence regarding its effectiveness as emergency contraception. Therefore, don't use TRI sprinter as emergency contraception. Instead, you can use any of the above medicines as emergency contraceptive pills. I hope this is helpful. If you have any further concerns do contact me through Chat Doctor. Best wishes, Chat Doctor.
