My Dr. is on the formulary panel for his HMO. While very conservative in prescribing medication, he still opines that eventually all of us older fellows will eventually be taking asprin, a bp med and a cholesterol med.
Read the stuff on medication on the DAN site, discuss with your doctor, know what the medications really do.
I started diving at 60 and will get my 100th dive at Coz this month. Lisinopril, Hydrocholorothiazide (drink lots of water and little coffee before diving), and Lovostatin all tolerated with no problem.
Dive on!
