Pharmacy store chains like CVS and Rite Aid said purchase limits will be placed on emergency contraceptives like Plan B.

The puchase limits come as demand for the product has gone up after Roe v. Wade was overturned on Friday.

"Due to increased demand, at this time we are limiting purchases of Plan B contraceptive pills to three per customer," Alicja Wojczyk, senior manager of external communications for Rite Aid, told CNN News in an email on Tuesday.

CVS Pharmacy’s senior manager, Matt Blanchette, also said that supplies are being limited “to ensure equitable access and consistent supply on store shelves.” CVS added that it has a “ample supply” of emergency contraceptives.

A spokesperson for Walgreens said on Monday that it will not be placing limits on its purchases of emergency conceptive in stores but that it will currently stop home delivery services.

“Walgreens is still able to meet demand in-store. We are working to restock online inventory for ship-to-home,” the spokesperson said.

Wendy Parmet, the director of the Center for Health Policy and Law at Northeastern University, told NBC News on Friday that restrictions on these types of products including birth control could also be challenged.

"The states that are trying to limit abortion from the moment of conception — not even from the moment of pregnancy, as the medical profession would define it — could well try to challenge Plan B, emergency contraception, potentially even IUDs,” Parmet said.
