What else can i do for hypertension than a beta blocker?

Other meds: To start with is lifestyle modifications, that you have most likely been instructed on but it never hurts to repeat - less than 2 grams of salt daily, less fluid intake (preferably less than 1/2 gallon/day), moderate exercise (~30 minutes/day). Labs are important, as some medications may be contraindicated. Diuretics are first line, ace inhibitoris, calcium channel blockers, arbs are other options.

Many: Depends on your individual profile, there are many other medications you can take such as ace inhibitor, angiotension receptor blockers, diuretics, calcium channel blockers, renin-inhibitor...They all work differently and most of the time, can be used together. Have a conversation with your doctor about this. Good luck.
