CVS will become the first pharmacy to limit painkiller prescriptions to seven days for certain conditions in an effort to combat the wave of opioid addiction.
New customers with acute short-term pain will only be able to fill a week's worth of opioid pills with one prescription.
Pills like OxyContin and Vicodin will be limited. The CDC says the average pill supply given by doctors increased from 13 in 2006 to 18 in 2015.
The chief medical officer of CVS Health said there are "certain physicians who are prescribing way too high of doses and way too strong of medications. We've got an epidemic on our hands." CVS hopes that limiting the amount of pills will reduce addiction and "the amount of human suffering."
