Hi, My 70 year old father had a quadruple bypass surgery a little over a week ago. He wants to take Ibuprofin for his body aches. The doctor at the hospital said he can take 3 -200mg every six hours. BUT, all the research I am doing online says he shouldn t take it after bypass and it can interact with blood pressure meds. Is it safe to use now? He thinks it s his only life saver! Thanks, Alison
