@gratchford Welcome to Mayo Clinic Connect! This is an important question to ask, definitely, about when to take certain medications.

Here is a link to the National Institure on Aging, and what they have to say about it: https://www.nia.nih.gov/health/medicines-and-medication-management/taking-medicines-safely-you-age#:~:text=Some%20medications%20need%20to%20be,two%20hours%20after%20you%20eat.

Do you use the same pharmacy for all your prescription medications? Ask to speak to the pharmacist, and take in your list of both over-the-counter and prescription meds. Explain you need some guidance to make sure you are getting the best benefits of all these, and not suffer unneeded side effects. Perhaps putting it this way will trigger that person to want to help you. A source I have also used is https://www.drugs.com/

Years ago I lived in an area where the pharmacist at a chain drugstore was actually a doctor from South Africa. He was so helpful in counseling us customers! He even caught a few "no-no"s for me! I miss having him to bounce ideas off of.
