Taking lots of medicine - side effects?

I am 65 & retired. I never had any Heart disease. My Gall- Bladder(1996) & Prostate(2011) are operated. Now my BP, Uric Acid, Lipid Profile, USG reports are all well within normal. Presently I am taking Deplatt A75, Pantodac 40, FBX 40, Lipikind 10, Calchek T40, CTD 6.25, Revelol XL 12.5. My BP remains 120/82 with medicine. In the last week my BP goes down to 110/70 & the present Dr. withdrawn CTD 6.25 & Revelol XL12.5. My job was transferable. The first doctor prescribed Aspicot 20, Pantodac, FBX 40, Amlopress 5 about 17 years back. After that all other doctors continued Aspirin, Antacid, Uric Acid, Lipid Profile related medicines. Although the related reports were normal. Now I understand that I have been addicted with the medicines. Please advise whether the medicines should be continued or are there any side effect(s)? May be suffering now a days. Please advise.
