What Are Progestin Side Effects?
Many types of oral birth control or implanted birth control devices are a combination of estrogen and progesterone, or progestin. Others come in progestin-only formulations and it’s possible to derive information about progestin side effects from these. Like all medications, progestin, which is a synthetic substitute for the hormone progesterone, does have side effects and these may affect people to greater or lesser degree. A few people will notice no change, some will have changes for a while that will gradually lessen or become tolerable, and others may find there are too many side effects to continue taking the medication.
