Do Urofruraginum and grapefruit tea affect the effectiveness of contraception?

Good morning, I have inflammation of pecherza so I take urofuraginum 50 mg and take as recommended by the manufacturer in the leaflet, does it not affect the contraception Vibin? At 7 p.m. I take Vibin, and the last pills for today I took at 4-5 p.m. I drink tea, which has in the composition of grapefruit 2.3% but vibin I drink only water, can I drink this tea before vibin and after? Let's assume that she drinks 2-4 glasses a day and eg a few minutes after taking vibin drinks this tea I have to protect myself and does it not affect contraception? Please reply
