Pennsylvania State officials say some reported shortages of Children’s Motrin and Tylenol are likely due to a spike in respiratory infections. Viruses like the flu and RSV have surged this fall and a few areas are already reporting more severe cases than previous years. Health experts say if parents can’t get Tylenol or Motrin, they should call their doctor to see if it can be prescribed. Also, doctors can recommend an adjusted dose if you have one product but not the other.
