What is Tri-Sprintec?
Tri-Sprintec is a type of birth control pill. It’s a “combined pill” and contains two hormones that work in the body like progesterone and estrogen. When you take Tri-Sprintec tablets correctly, your chances of getting pregnant are very small — less than 1%.
It’s a 28-day pill, which means you take it every day unlike some other birth control pills which have a seven-day break between packs. There’s a lower dose version too, called Tri-Lo-Sprintec (aka Tri-Sprintec Lo).
How does Tri-Sprintec birth control work?
The two hormones in Tri-Sprintec trick the body into not making the necessary preparations to become pregnant. They stop the ovaries from releasing an egg, and try to block sperm from reaching and fertilizing the egg by thickening the fluid in the womb.
Taking the combined pill also stops your uterine wall from becoming thicker every month. When it stays thin, it’s not as easy for a fertilized egg to attach to the wall and grow. This effect can also mean you’ll get lighter or more regular periods.
There are 28 Tri-Sprintec tablets in each pack: 7 gray pills, 7 light blue pills, 7 blue pills and 7 white (inactive) pills. All you need to do is take the pills at the same time every day, in this order, and repeat every 28 days (so on the plus side, there are no breaks to remember).
What’s the difference between Sprintec and Tri-Sprintec?
They contain the same hormones, but Tri-Sprintec is a multiphasic pill. Sprintec is a monophasic pill. In monophasic pills, the amount of hormones delivered into the body stays the same through the four-week cycle. In multiphasic pills, it changes throughout the course of the cycle. Tri-Sprintec has three phases that last for seven days each: gray pills, light blue pills and blue pills.
The gray pills contain 0.18mg norgestimate and 350mcg ethinyl estradiol; the light blue pills contain 0.215mg norgestimate and 350mcg ethinyl estradiol; and the blue pills carry 0.25mg norgestimate and 350mcg ethinyl estradiol. The white pills don’t contain any hormones.
All 21 active pills in a Sprintec pack are blue (and contain the same level of hormones listed in the blue pills above).
Whether you choose a multiphasic or monophasic pill depends on how your body reacts to hormonal birth control. Some women find that they get better control of menstrual symptoms when using a particular kind. Let the doctor know if you’re unsure which type of pill is best for you.
