I've had hypertension for years, and have been on meds with no problems. I take Lisinopril and HCTZ. I am a Type 2 Diabetic, and it is imperative that I keep my BP in a normal range.

I'm also on Lipitor for cholesterol. No problems with that med, either.

You could try it on your own for awhile - exercise, no salt, lose weight. Do you have a BP monitor at home? They're not terribly expensive and you can keep track of your numbers on your own.
