Occupational asthma is asthma caused by, or worsened by, exposure to substances in the workplace. These substances may cause asthma in one of 3 ways:
An allergic reaction (like people with allergies who develop allergic asthma)
An irritant reaction (like a person that reacts to smoking with asthma)
A reaction which results in chemicals that occur naturally in the body, building up in the lung and resulting in an asthma attack

The culprit is aspirin, that trusted wonder drug, along with other common over-the-counter (OTC) painkillers. These are medicines we use without thinking twice. But in about one in five people with asthma, these drugs can make symptoms worsen. They can even cause dangerous or even fatal reactions.
"It happens a lot more than people realize," says Phillip E. Korenblat, MD, spokesman for the American Academy of Allergy, Asthma, and Immunology. "If you went to any ER right now, you'd be likely to see people with asthma who were there because of a bad reaction to these drugs."
The problem doesn't end with OTC painkillers. In fact, many remedies for colds, sinus problems, and even indigestion contain the same potentially dangerous ingredients.
So before you grab a bottle of pain reliever for that headache, you need to learn some dos and don'ts.
How Do Pain-Relief Drugs Work?
In a certain way, all pain is in your head. When we feel pain, it's the result of an electrical signal being sent from the nerves in a part of your body to your brain.
But the whole process isn't electrical. When tissue is injured (by a sprained ankle, for instance), the cells release certain chemicals. These chemicals cause inflammation and amplify the electrical signal coming from the nerves. As a result, they increase the pain you feel.
Painkillers work by blocking the effects of these pain chemicals. The problem is that you can't focus most pain relievers specifically on your headache or bad back. Instead, it travels through your whole body. This can cause some unexpected side effects.
What Are the Risks for People with Asthma?
If you have asthma, painkillers called nonsteroidal anti-inflammatory drugs (NSAIDs) can be risky. They include aspirin, ibuprofen, naproxen, and ketoprofen, the active ingredients in medicines like Bufferin, Advil, and Aleve.
