Do Nifuroxazide and alcohol weaken the effect of birth control pills?

If at 11.00 I took one tablet of Nifuroxazide Gide Richter, and at 20.00 as usual the Contraceptive pill Daylette, will the effectiveness of protection against pregnancy be preserved? I have one more question about the absorption of Daylette, if for 3 days in a row I consumed beer, but did not drink tablets with it, the beer was drunk at least an hour after taking the tablet. Does this have any impact on their effectiveness?
