Worried mothers and fathers sit on social media sites searching for a treatment to reduce fever for their young children with the start of the cold and flu season, as pediatricians and pharmacists try to reassure them that there are alternatives even if certain drug names are missing. For six months, some retail sellers' shelves containing acetaminophen for children have been emptied, and later, ibuprofen products such as Tylenol liquid and Advil. Canada also promised to speak with suppliers earlier this summer regarding the shortage across the country. However, doctors say there is no need to panic because there are options, as Dr. Sarah Reid, an emergency and pediatric physician in Ottawa, sees a "large number" of patients with viral illnesses accompanied by symptoms such as fever, cough, vomiting, and diarrhea, adding: "I think we must always keep in mind that the vast majority of fevers in younger vaccinated children who were previously healthy are caused by viruses and usually resolve on their own." Reid mentioned that it is essential for people to know that fever is an indicator that the immune system is working. She also said the cornerstone is to ensure that the child is consuming well and using fever-reducing treatment to keep warm, as differences can be found in formulations that pharmacists can prepare for children. In the same regard, Mina Tadros, an assistant professor at the Leslie Dan School of Pharmacy at the University of Toronto, said the issue of providing an overview of over-the-counter fever treatments has not subsided.
