Triquilar is a combined oral contraceptive pill used to prevent pregnancy. Each pack contains 21 active white tablets, each containing synthetic hormones, and 7 inactive brown tablets. The active tablets contain two types of female hormones: an estrogen (ethinyl estradiol) and a progestin (levonorgestrel). Triquilar works by stopping the release of an egg from the ovary and by thickening the cervical mucus, making it harder for sperm to reach the uterus. It is important to take Triquilar at the same time every day to maintain its effectiveness and reduce the risk of unintended pregnancy. Before starting Triquilar, it is important to consult with a healthcare professional to determine if it is the right contraceptive option for you.
