Change (lower) in BP after changing pharmacy?

I'm afraid, and am aghast, that you may be right on the money. And if you still have some of the old prescription, even one representative tablet, you may wish to take it to a university chemist and ask them to assay that/those pills for their relevant content per gram weight or volume. With a formal report, you might present that to the state board and see what happens. If you were being ripped off..............................mind you, they may have received no feedback from customers and not have been the wiser. It's not as if they test each batch they purchase. But the FDA should be aware of the problems with your supply. And from whom it was purchased.

Have you called your doctor that blood pressure in my opinion is too low. And if the new pharmacy isn’t using a different brand that could be the difference
And please talk with the pharmacy as well.
Good luck

I had the same issue. My GP cut the dosage in half. I don’t take any if my morning BP is less than 130. It seems to working for me. I test BP as soon as I get up in

Yes, I always test before taking AM or PM doses. And in between if feeling off. I have no such "parameters" as MD and NP more concerned about their liability than my well-being.

Yes. I have called MD who is more concerned about liability than my well- being. How times have changed!

I was afraid of that particularly since the first pharmacy closed due to bankruptcy. They may have been obtaining medications from an unreliable source to save money. New pharmacy has different manufacturers for both medications. Unfortunately, I did not have any of the old ones left. These types of issues are what makes us all so untrusting of the medical fields.

Hi @jkb2, and welcome to Mayo Clinic Connect! Changes in blood pressure can be scary and I am glad to see you are addressing your recent sudden drop.

I experienced the opposite, a pretty drastic increase in blood pressure that totally caught me off guard. I made a trip into my doctor’s office to confirm my at-home device was still working well. In addition to pharmacy mistakes you suspect, I found out monitors can lose their accuracy over time. I was having symptoms when the episodes were happening so my log of readings/symptoms became helpful.

I found information about symptoms that can happen with a sudden drop in blood pressure: Confusion, Blurred vision, Lightheadedness, Nausea, Fainting, Neck or back pain, Headache, Heart palpitations

You no doubt have a consistent routine and lifestyle, but here’s a list you could review then use to assure your doctor nothing has changed when you take your blood pressure: https://www.wellahealth.com/blog/10-causes-of-inaccurate-blood-pressure-readings/

You mention contacting your doctor’s office. What did you find out from them? Have you had symptoms that your blood pressure drop may be causing?

Im sorry to hear this. For the past ten years i have dealt with what was best for the bottom line. Im a 79 year old female. Value to some, non existent. To others. Wrong, i am of value, i do carry responsibility that i dont mind carrying. I dont give a flying xxxx if my supposed medical experts feel they have to put up with my concerns. I have to care. If something is wrong, i have to fix it. If a med is wrong, and i know it, change it. It’s my right. And yours.

Change doctor. Something not right.
I hope you live in an area where you can get a second opinion.
