T49: Poisoning by topical agents primarily affecting skin and mucous membrane and by ophthalmological, otorhinolaryngological and dental drugs

T49.2: Poisoning: Local astringents and local detergents

The relevant agent is usually applied topically. Topically applied agents are those that are not taken as tablets or received as injections, but instead usually applied directly to the place where they are intended to have effect. These include, for example, ointments, drops or solutions for gargling.

Astringents can be drying, hemostatic and anti-inflammatory. Detergents reduce the surface tension of water and have a fat-dissolving effect. This kind of agent can cause poisoning if too much of it is taken. The agent may also be administered or taken by mistake. The symptoms can vary greatly depending on which agent has caused the poisoning.
