Risk of environmental impact of dimenhydrinate can not be excluded as ecotoxicological data are missing.

"According to the European Medicines Agency guideline on environmental risk assessment of medicinal products (EMA/CHMP/SWP/4447/00), use of dimenhydrinate is unlikely to represent a risk for the environment, because the predicted environmental concentration (PEC) is below the action limit 0,01 μg/L."
