The Food and Drug Administration has added EpiPens to its list of drug shortages, but says people should still be able to find the emergency treatment for allergic reactions.
The FDA says the shortage doesn't mean people can't get EpiPens, but people may need to turn to a different brand.
Officials say if that's the case, people should learn how to use a different brand because each brand functions a little bit differently.
They say learning a new brand could make a big difference in an emergency situation.
The FDA also recommends that people who need EpiPens should check their supply now, looking at injectors and expiration dates to see if they need to look at alternatives.
The FDA expects the shortage to be short term, and says it's working to understand and control the shortage.
