Asthma: Everyday Pain Relief (cont.)
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.
Other pain relievers are potentially less dangerous. Acetaminophen -- the active ingredient in Tylenol -- works differently. It poses a much lower risk of problems for people with asthma, although like any drug, it does have side effects of its own. You shouldn't take any over-the-counter painkiller for more than 10 days without your health care provider's approval.
Why are people with asthma at special risk from NSAIDs? Experts aren't sure of the exact cause, but it seems that these medicines can trigger a dangerous immune response. People who are older and who have more severe asthma may be more sensitive to these drugs.
Symptoms include a cough, runny nose, shortness of breath, and wheezing. In some people, these medicines can also cause swelling of the face or hives. If you have any reaction, get help right away.
"One problem is that people may not realize the connection between asthma and a painkiller," Korenblat tells WebMD. "It can take up to two hours for the medicine to cause the effect, so you may not see the link."
In general, it's best for people with asthma to avoid NSAIDs. And people with asthma who also have sinus problems or nasal polyps -- swollen tissue that grows from the sinuses into the nasal passages -- should not use any NSAIDs, says Korenblat. "The risks of using these medicines are much higher for them."
Asthma treatments may help. Korenblat says the asthma medicines Singulair and Accolate may partially protect people from bad reactions to NSAIDs. Some doctors "desensitize" people to NSAIDs by giving them small doses and gradually increasing them over time. Eventually, your body may be better able to tolerate the NSAID and won't have such a dangerous reaction. However, this process must be done in a medical setting, since even tiny amounts of these drugs can trigger a dangerous asthma attack.
