are they safe to take together,

been on cit for four weeks

i took 800mg of ibuprofen today and 1600mg yesterday

was given some of the 1600mg when i was taken to hospital for bad pain, turns out to be costochondritis potentially with a gastric problem they think. they gave me 5mg of diazepam so i coils sleep and prescribed a further 3 x 5mg which i havent taken yet.
up until 2 nights ago i was taking 5mg of zopiclone.

however the hopspital would have known i was taking citalopram, so why give me ibuprofen.i am worried please help

i took lansoprazole for two months with a weeks break inbetween and my doctor has asked me to come off it now.

many thanks janine
