The Most Addictive Over the Counter Drugs

9. Painkillers

Of course, the more powerful painkillers require a prescription, however, when taken in large enough doses, over the counter painkillers can be just as damaging. One of the most common painkillers is ibuprofen and when taken in doses higher than the recommended amount or at an increased frequency, liver damage can occur.

In terms of addiction, there are over the counter painkillers that contain codeine. These are commonly found in drugs that target menstrual cramps, back pain, and headaches. In many cases, people become addicted accidentally which many are referring to as a 'hidden addiction.' In order to relieve their pain, they need to take more and more, resulting in an addiction.
