My Daughter Has Taken Cymbalta 60mg For 31/2 Yrs, Is

My daughter has taken cymbalta 60mg for 31/2 yrs, is taking atenolol and flecanide. Her Dr just prescribed paxil 10mg to address stress related issues; she's in last phase of Paramedic school. Can paxil be safely taken with cymbalta and flecanide. The RX printouts from pharmacy have me wondering if something may have been overlooked, but Dr isn't in today.
