Facebook said on Monday it had removed some ads that contained misleading information about HIV prevention drugs following an outcry from activists, health experts and U.S. lawmakers.

The ads linked the drugs, which are known as PrEP and designed to prevent HIV, to severe bone and kidney damage and were placed by personal-injury attorneys.

LGBT+ advocacy groups have for months been pressuring the U.S. company to remove the ads, pointing to a multitude of research showing that the medication is safe.
