Depends why Rx'ed?
Whether and for how long you should take these (and any) medications depends on why they were prescribed in the first place.
Your BP may be normal on meds, but is it high if you don't take the meds? (that's hypertension.) talk to the dr. Who prescribed them in the first place, so you can understand why they wanted you to take them and whether you need to stay on them long-term or not.
