Symptoms and treatment of specific poisons vary (see table Symptoms and Treatment of Specific Poisons ). Including all the specific complexities and details is impossible, although cross-references are made to other entries in the table where appropriate. Consultation with a poison control center is recommended for any poisonings except the mildest and most routine.
