Many doctors and pharmacists agree, but caution that like all drugs, there are serious side effects to consider with tofacitinib. “People are often looking for the magic bullet, saying, ‘I hope this is the breakthrough and the drug with no side effects,’ and I would put cold water on that,” says pharmacist Donald Miller, professor and chair of the pharmacy practice department at North Dakota State University in Fargo. “It’s always nice to have different drugs available but it [won’t] necessarily be more effective or safer than the drugs already out there.”
