Can Althea Pills Be Used As Emergency Contraception?

Hello! I had unprotected sex with my partner last night and I would like to as if the Althea pills are safe to use as emergency contraception? I twice do that with Diane 35 but I am thinking to shift on other kind of pill because I do not like the side effects of taking it. So, is it okay to use Althea pills as emergency contraception and if yes, how to take it? Thank you so much.
