My Son Who Is 28 Has Been Taking Lisinopril For

My son who is 28 has been taking lisinopril for high blood pressure and 10 mg of celexa for anxiety .He is out of the lisionpril and he cannot get the doctor to call him back . He has to go out of town for work and i was wanting to give him a weeks worth of my high blood pressure medicine called Tribenzor 40-5 25 .From what i read it is safer than the lisinopril but what do you think ?
