Yes Its a mild blood pressure medication.

Your detoxing off several drugs at a time right??? If so it’s almost common place to have blood pressure increase. Are you able to check your BP numerous times a day ??
If so please do , if that bottom number stays around 100 or above you need to contact your Pdoc or GP right away and well ... considering it’s the weekend .... because that’s when trouble always hits , right? You might need a walk in clinic at least , they can put you on a safe low dose blood pressure medication to get you through the weekend then you can follow up with Pdoc or GP

It’s very unlikely you became toxic off Indural so maybe take one to bring your pressure down so there won’t be worries of heart attack or stroke.

I’m no medical professional of course, but it’s what I would do to bring it down until I could get with my Doctors.

Stay safe
