Keep a supply of your medications in your purse or wallet in case of emergency. You never know when delays happen e.g. a car breaks down or you get stuck etc. A backup supply ensures you don’t have to worry about your next meds!
Also, a good backup is to write out a copy of your daily drug regimen for family members. It is very key that if you were somehow setback in any way that someone should know 'what you take and when you take it'.
