If recording is based on substances and products and specifies the type of reaction in "type":

<<105590001 | Substance (substance) | OR <<373873005 | Pharmaceutical / biologic product (product) |

If recording is based on finding concepts precoordinating the type of reaction :

<<418038007 |Propensity to adverse reactions to substance|
