People use prescription or over-the-counter (OTC) medications to help treat underlying conditions or temporary illnesses. It’s estimated that more than 131 million people, or 66% of adults, are actively taking prescription drugs. And this doesn’t account for the medications that we can purchase without a prescription, including common pain killers or cold and flu remedies. It’s important to be aware that many medications have side-effects, some of which can interfere with the way our bodies heal themselves. When wounds take longer than normal to heal, then there may be an increased risk for scarring down the road.
