The allergy to a drug that can cause a drug reaction is so severe it can kill.

The allergy is the same as a severe allergic reaction to a common cold, but can also be deadly.

Now, a team of researchers is looking into how to prevent the reaction.

That includes finding a way to help people avoid the reaction by keeping a record of the drugs they take.

The new research is published online May 25 in the journal Science Translational Medicine.
