Prescription drug costs are increasing, using an app like Good Rx to check the prices of your medications can help you save money. Many over the counter medications have a generic or store brand available which can be much cheaper than a brand name medication. Some over the counter medications are offered as stock bottles behind the pharmacy counter. I mention getting a popular allergy medicine for $3 for 50 pills by just asking the pharmacist.
However, the best way to save money on medications is to not need them in the first place. Many chronic diseases like heart disease and diabetes can be prevented with lifestyle.
