Levest is a combined oral contraceptive pill, commonly used for the prevention of pregnancy. It contains two active ingredients, ethinylestradiol and levonorgestrel, which are synthetic versions of the naturally occurring female sex hormones, estrogen and progesterone, respectively. Levest works by preventing ovulation, making it harder for sperm to reach an egg, and thinning the lining of the uterus to reduce the likelihood of egg implantation. In addition to contraceptive use, Levest may also be prescribed to help manage menstrual cycle irregularities, reduce menstrual pain, and treat acne in some cases. Like all medications, it may have side effects and is not suitable for everyone, so it's important to consult a healthcare provider before starting Levest.
