I get 200 by prescription for like $40
It's much cheaper to pay cash. Maybe 7 dollars for that same amount of pills. You are losing money. If you are in the USA, buy at Costco and buy OTC bottles. Another pro tip is check Costco for cash price on any medication you take chronically. Ask for 350 pills without insurance. It's often much much cheaper to pay cash and not use insurance at all. Buy a years supply. In the case of imodium the pricing I found was higher at the pharmacy (cash) than OTC in the Kirkland bottles but most of my medications are cheaper bought without insurance. If you have a useful doctor they will write the script for the whole year. If not, maybe find a new doc. I want my doctors to be as smart or smarter than me.
Update on the imodium crisis. The FDA/DEA are discussing putting it behind the counter like Sudafed (used to make Crystal Meth) because a few people US-wide in the last 10 years have died from imodium milkshakes to stop heroin withdrawals. It's sad but an obvious failure of ethics and use of the utilitarian dilemma. Our politicians deserve to be hung from a tree.
