My mother is 83 years old and has COPD, High blood pressure, High cholesterol, and prednisone induced diabetes 2.  She also had a mild heart attack almost 1 yr ago. She weighs 94lbs. 

My sisters wanted to stop giving her most of her pills and wanted to try a holistic approach (vitamins, etc.).  They asked her Pulmonary Doctor if they could and he said yes.  He told them to continue the metropol and her COPD medicines.

I insisted that we consult with her heart Doctor who said to continue her medicines especially since some could have a rebound effect.  I scheduled an appt and afterwhich he said to continue with all meds.  He did say that her EKG was good -- better than her last visit.

HOWEVER, I just recently found out that my sisters went ahead and stopped giving her all of her meds.

I had noticed that her oxygen levels had been very low as well as her BP was very low every two days.

So with that said, we have been playing with her health -- some days giving her meds (when I am there) and sometimes not (when my sisters are there).

My question to you is:  What are the serious ramifications of this yo-yo type of care?  Should I be concerned about this and if so need to know what to tell my sisters in order for them to stop.  Or maybe I am the one who needs to accept it.

Here are her meds: 

Prednisone 2.5 1 a day
glipizide 1/2 pill a day
Welchol 3 pills twice a day
Isosorbide 1 in the morning
Spiriva 1 inhale a day
Advair inhale twice a day
Metropol 1/2 pill twice a day
Ramiphril 1 a day
albuterol and ipratropium treatments 4 times a day

Oxygen 3.5 - 4
