T48: Poisoning by agents primarily acting on smooth and skeletal muscles and the respiratory system

T48.6: Poisoning: Antiasthmatics, not elsewhere classified

Asthma medications are typically used to treat asthma. But they can also be used for certain other disorders that involve the airways becoming inflamed or constricted. Air enters the lungs through the airways. The lower airways begin with the trachea (windpipe) and continue into the lungs. The airways branch out further into the lungs, becoming smaller and smaller. Many asthma medications can expand the lower airways, for instance. Some asthma medications can primarily counter allergic reactions.

A drug can cause poisoning if, for example, too much of it is taken. The drug may also be administered or taken by mistake.

Depending on exactly which medication has caused the poisoning, there can be a variety of symptoms. There can be nausea or vomiting, for example. Some asthma medications can make the heart beat faster. Restlessness may also occur. Seizures may also occur.
