What is Tri-Estarylla?
Tri-Estarylla is a combination hormone medication that’s used to prevent pregnancy. It contains two different hormones that work to stop you from getting pregnant: norgestimate and ethinyl estradiol. When used correctly it’s over 99% effective at preventing pregnancy.
It releases varying levels of hormones in the active birth control pills, making it follow your natural cycle more closely. This is known as tri-phasic birth control. This phased dose can be better to control PMS symptoms that are usually associated with your period. Tri-Estarylla comes in packs of 28 pills.
How does Tri-Estarylla work?
The hormones in Tri-Estarylla work in three different ways to prevent pregnancy. First, it stops your body from releasing an egg during ovulation. It also stops your womb lining from thickening so an egg can’t implant itself. Finally, it makes your cervical fluid thicker so that sperm can’t get through.
So it all works together to make pregnancy less likely. Tri-Estarylla can also help to regulate your period and make it lighter. It can even help with PMS symptoms that many women experience during their menstrual cycle.
What doses of Tri-Estarylla are there?
Every package of Tri-Estarylla has 21 active birth control pills and 7 inactive pills. The ‘inactive’ pills don’t have any hormones. Taking a break from the hormones means you can have your period, while still taking the inactive pills helps you remember to take it everyday.
The active birth control pills contain norgestimate and ethinyl estradiol (0.18mg - 0.215mg - 0.25 mg/0.035mg) to phase the delivery of hormones throughout the month. These hormones change through the month on a 7/7/7 basis, which means 7 days at each phase of hormones.
The pills are color-coded to make it simple to identify which dose of hormones they have. You’ll start off taking the white pills for seven days, which have 0.18 mg of norgestimate and 0.035 mg of ethinyl estradiol.
On days 8-15 of each pack of Tri-Estarylla, you’ll take the light blue pills which have the same dose of estrogen and 0.215mg of norgestimate. Then you’ll take the blue pills for seven days, which have 0.25mg of norgestimate. Finally, you take the inactive pills, which are green and don’t contain any hormones.
There’s a low hormone dose version available Tri-Lo-Estarylla which may be better for people who have side effects from birth control with a higher dose of hormones. There’s also a version that gives you the same dose of hormones each month (known as mono-phasic) called Previfem.
