26 May 2020 --- The US Food and Drug Administration (FDA) has approved a mix of lactic acid, citric acid and potassium bitartrate as the first non-hormonal prescription gel for the prevention of pregnancy. Evoferm Biosciences’ Phexxi is touted as being a new class of female-controlled birth control for use in-the-moment and works by maintaining the vaginal pH within the normal range of 3.5 to 4.5 – an acidic environment that is inhospitable to sperm. Phexxi is set to launch in early September in tandem with a telemedicine support system, tapping into the major trend of remote health services.
