Levosert® is a levonorgestrel intrauterine system (LNG-IUS) newly launched in the UK for contraception and management of heavy menstrual bleeding. It contains 52mg levonorgestrel (identical to Mirena®) in a
reservoir mounted on a T-shaped polyethylene frame.
Injectable progestogen-only contraception is a popular and effective method of contraception and until now, in the UK has largely been administered as Depo-Provera®, an intramuscular (IM) injection of 150mg medroxyprogesterone acetate (DMPA).
How effective is 20mcgEE/3mgDRSP as contraception?
20mcgEE/3mg DRSP is of comparable effectiveness to other combined oral contraceptives. [1,2,3] A large US observational study reports lower failure rates amongst users of a 24/4 EE/DRSP regimen than a 21/7 EE/DRSP regimen. The study also suggests greater contraceptive effectiveness of a 24/4 EE/DRSP regimen than with a 24/4 regimen containing EE in combination with norethisterone.
The combined oral contraceptive Zoely® (Merck, Sharp, and Dohme Limited) has been licensed in Europe since 2011 and will be available in the UK from May 2013. Zoely will be the second UK combined oral contraceptive (COC) to contain estradiol and to be formulated as an extended regimen since the introduction of Qlaira® (Bayer plc.)
Diaphragms are non-hormonal barrier methods of contraception that protect women against pregnancy by preventing sperm reaching the cervix. A single size contraceptive cap, FemCap, has been available since 2004, but until recently diaphragm products have been made in a range of sizes and designs. As a result
women may have been required to try several types of diaphragm during the fitting process.
