There's no problem with vitamin B.
Drugs that may decrease the effectiveness of the pill include penicillin-class antibiotics (those generic names ending in -cillin), tetracyclines (those generic names ending in -cycline), barbiturates such as butabarbital and phenobarbital, rifampin, Dilantin, Tegretol, and griseofulvin.
