What are TriNessa Birth Control Pills?
TriNessa birth control is a combination birth control that is taken once a day to prevent pregnancy. The medication is an oral contraceptive that contains two types of hormones: estrogen and progestin.
Like other combination pills, the hormones in TriNessa are effective at preventing ovulation (the release of an egg from the ovaries). These hormones also reduce the chance of fertilization from occurring from causing changes to the uterus lining and increasing the thickness of the vaginal fluid. Both changes make it difficult for sperm to reach the uterus and attach to the uterus wall. If a fertilized egg cannot attach to the lining of the uterus, it passes out of the body during a woman’s menstrual cycle.
