I found out my 90-year-old father has been taking Xanax when he's feeling anxious, which seems to occur more and more lately. The problem is, he's driving after taking it. One day this week, he drove over to pick me up and I noticed he acted like he was in slowwwwwwww motion and he would slur his speech. I warned him that an accident of any kind, his fault or not, was sure to bring scrutiny. Police and potential plaintiffs most times assume that all 90 year olds are on a tons of medications. I told him that he should call me to drive him, or, talk to his doctor about an alternative medication that will help him with anxiety and depression, but still be OK to drive. He is pretty healthy for his age and takes a small dose of blood pressure medication and something for cholesterol. He isn't diabetic, but has tendencies which he controls with a good diet. He has never smoked or used alcohol. Is there a medication we should look into? Thanks all!
