Your mother should have an expectation of what results she should see from using a medication. Understanding of side effects is also important. Questions like: How will this med improve my blood work? Why is this med a good choice for me? What type of results should I look for in the long term to determine if this med is working well?
The site www.drugs.com is a good place to read up on meds and side effects.

Best wishes on medication choices.
Best of luck.
