No longer-term studies have been performed to assess the long-term effects on infants of levonorgestrel in breast milk. There are conflicting recommendations about use of Mirena while breastfeeding. The U.S. CDC does not recommend any hormonal method as a first choice of contraceptive for nursing mothers, although progestin-only methods, such as Mirena, may be used with close follow-up or when the benefits outweigh the risks. The World Health Organization recommends against immediate postpartum insertion, citing increased expulsion rates. It also reports concerns about potential effects on the infants liver and brain development in the first six weeks postpartum. However, it recommends offering Mirena as a contraceptive option beginning at six weeks postpartum even to nursing women. Planned Parenthood offers Mirena as a contraceptive option for breastfeeding women beginning at four weeks postpartum. Contraindications

Estazolam, sold under the brand name Prosom among others, is a tranquilizer medication of the triazolobenzodiazepine (TBZD) class, which are benzodiazepines (BZDs) fused with a triazole ring . It possesses anxiolytic, anticonvulsant, hypnotic, sedative and skeletal muscle relaxant properties. Estazolam is an intermediate-acting oral benzodiazepine. It is used for short-term treatment of insomnia. It was patented in 1968 and came into medical use in 1975. Medical uses
Estazolam is prescribed for the short-term treatment of certain sleep disorders. It is an effective hypnotic drug showing efficacy in increasing the time spent asleep as well as reducing awakenings during the night. Combination with non-pharmacological options for sleep management results in long-term improvements in sleep quality after discontinuation of short-term estazolam therapy. Estazolam is also sometimes used as a preoperative sleep aid. It was found to be superior to triazolam in side effect profile in preoperative patients in a trial. Estazolam also has anxiolytic properties and due to its long half life can be an effective short-term treatment for insomnia associated with anxiety. Side effects
A hang-over effect commonly occurs with next day impairments of mental and physical performance. Other side effects of estazolam include somnolence, dizziness, hypokinesia, and abnormal coordination.In September 2020, the U.S. Food and Drug Administration (FDA) required the boxed warning be updated for all benzodiazepine medicines to describe the risks of abuse, misuse, addiction, physical dependence, and withdrawal reactions consistently across all the medicines in the class.
