Demand for morning after pills have led to retailers having to limit purchases

Amazon has limited sales of morning after pills as demand spikes following the U.S. Supreme Court ruling overturning Roe v. Wade.

There is now a limit of three Plan B units per week on emergency contraceptive pills sold through its website.

Other U.S. retailers are also capping purchases of emergency contraceptive pills like chain pharmacy, CVS and Walmart.

Plan B is an emergency contraceptive that can be taken within 72 hours after sex. It is a synthetic form of the hormone progestin which delays ovulation briefly and prevents pregnancy.

Demand has surged following last week’s U.S. Supreme Court ruling overturning Roe vs Wade, ending the constitutional right to have an abortion.

Since the reversal of Roe v Wade, women have tried to find ways to control their reproductive health, by stocking up on emergency contraception.

Social media is flooding with calls to stock up on Plan B in anticipation of possible restrictions on contraceptive pills.

Meanwhile, some US companies have committed to paying staff travel expenses for those wanting an abortion.
