DH was at the doctors yesterday and I asked the Dr. if he could substitute aspirin for his blood thinner. About a year ago he really needed something stronger to thin his blood. Now that his blood counts were better, the Dr. said we could switch back to aspirin. Dr's don't always review your meds..face it , they are busy and the 20$ a month saved isn't much to them.
Keep track of all your meds and the reason you are taking them. Things change and new generics become available.
