@kbm1967 hi and thanks for taking care of your mom. I see my post was last February and I’m trying to remember how long I’ve been on Losartin. Well it’s been at least a year right? And yes I am struggling with brain fog and total forgetfulness to where I’m concerned I’m getting dementia! Maybe this is normal mental stuff for a 72 year old woman but I think not. I’m also on other meds that could easily produce these symptoms so I’m afraid I’m not much help here. I do think the med can cause what your mom is experiencing. I’m definitely going to look into it for myself since your situation got me thinking about it again. One thing to consider: a lot of docs don’t really know all the pharmacologic details on the drugs they use. It’s annoying, but they tend to dismiss us because they simply don’t know. So why don’t they just say that?! Our best bet for finding accurate information might be to ask a pharmacist. I think even some pharmacists might also dismiss the question out of simply not working in a position where they need to know such detailed drug information. I’d suggest contacting a compounding pharmacist and talking to them in person. I think they have a stronger commitment to learning about drug side effects and they have a healthy curiosity that drives their motivation. If you don’t get a satisfactory response try 1 or 2 more. I’m going to do that too. Check back with your update. I’ll try to do the same.
