Imo there are more sales catalysts than meets the eye with CVS. The assumption at the moment appears to be that Actipatch demand is simply based on the random occurrence of a pain sufferer that happens to spot Actipatch in the aisle. But let's not forget that CVS Pharmacy is now CVS Health and they now have the ' Minute Clinic ' in many locations where a qualified medical professional i.e. Physicians Assistant will be on duty to diagnose and treat patients. Imo it would be reasonable to assume people coming in for acute injuries like a sprained knee would be recommended an Actipatch for pain relief and healing.
