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

If a term is not readily visible in the alphabetical listing of poisons, try searching the current web page according to the conventions of your device and browser. | ||
* Inclusion of one poison with another (eg, toluene with benzene) in a single row indicates that the terms are synonymous, that the poisons are chemically related, or that one poison is an ingredient or impurity of the other. Lists of substances containing the poison are examples and are not all-inclusive. Most drugs are included as members of a class (eg, beta blockers) and only the most common and important drugs will have a separate row entry. | ||
