Levonorgestrel + Ethinylestradiol is a combination drug that is made up of levonorgestrel and ethinylestradiol. It is a hormonal contraceptive that represses ovulation by regulating the pituitary secretion of gonadotrophins, luteinizing hormone and follicle-stimulating hormone through a negative feedback loop. This drug diminishes sperm penetration if ovulation occurs by adjusting cervical bodily fluid; then causes changes in the endometrium which lessen the danger of nidation and may change the tubal transport of eggs through the fallopian tubes. Taking this drug can increase the risk of blood clots, stroke, and heart attacks. One may have more risks if she has high blood pressure, diabetes and high cholesterol and if she is overweight. You can be at high risk for stroke or blood clots in the first year of taking the said pill. Smoking can also cause you to have a higher risk of thromboembolism.
