Carol,
I understand your concern over the use of Aricept and Namenda. My husband is on both of these. He was going down hill fast with moderate AD. After taking these, he came back to almost normal. They have been so successful with no side effects. It is my understanding that all medicines will stop working at some point, so while they are working--keep going with it.
A Pharmacist at a government facility decided to take my husband off Aricept and replace it with something else, just because that facility was not carrying that brand. After much reasoning with them, which failed, we decided to continue the Aricept and pay for it ourselves. With RX plan, we just paid a co-pay. 3 months later the Doctor decided to reinstate the Aricept with a small copay. This medicine slows the progression of the disease. Another medicine might not work or it would take 2-3 months to see if a new medicine would work.
When my husband was in the 'donut hole' of his insurance, we did a lot of research of how to get the medicine. If you do not qualify for VA, or DHS, you have a good chance of getting the medicine free or at a discounted price from the manufacturer. Just type in 'Arcept' in the address bar, and the manufacturer will come up. You can get applications from your MD. or maybe from the web. While waiting for our answer, the doctor supplied the medicine with samples at no cost.
Now there is an Aricept 23 that may give some benefit after the Aricept quits working. From what I have read, Doctors don't agree on using this '23' because of such possible serious side effects.....but all of the meds. have that possibility.
I asked the doctor how to tell when the medicine has quit working. He said , "when he doesn't know when he needs to go to the bathroom." or "when he doesn't recognize his house.
I believe that no director of any facility has the right to tell you when to stop the medicine. Only your doctor should advise you.
