The Most Addictive Over the Counter Drugs
Although many drugs require a prescription, there are plenty over the counter medications that increase one's risk of side effects — including addiction. If a drug is not taken as prescribed, the user may find that they end up in a cycle of addictive thoughts and behaviors. Once a dependence develops, withdrawal symptoms often set in.
Without realizing it, users need to take higher and higher doses in order to feel normal. There have been numerous tragic accidents regarding over the counter drugs and millions more abuse them each year, increasing their risk of liver, heart, and brain damage. Based on their accessibility, the following ten drugs are being abused and addiction is an unfortunate side effect.
10. Cough Syrups

The active ingredient in dozens of cough syrups is dextromethorphan. When consumed in large doses, users experience distortions and euphoria. Cough medications have been a great concern amongst the teenage population, as many parents are unaware that these products can lead to these dangerous effects.
Since a large dose of cough medicine mixed with alcohol can be fatal, it's critical that you follow the recommended dose at all times. Once a dependence occurs, withdrawal symptoms will surface after discontinuing use — including severe depression. Although not much is known about the long-term complications, brain and heart damage may occur.
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.
