The concurrent proliferation of magnetically sensitive programmable CSF shunt valves and household items that generate substantial magnetic fields has caused concern among patients, parents and providers about the potential consequences of inadvertent valve reprogramming. This growing concern led the FDA to issue a warning to individuals with programmable valves in 2014, which deemed the programmable valves safe for use but vulnerable to IR when household devices such as tablets or cell phones are placed within 2 inches of the valve. The FDA recommended further study, stating that no systematic evaluation had been performed regarding the prevalence of accidental valve adjustments.
