The most common signs of a believed allergic reaction to carpet are headache, skin rash and upper respiratory discomfort. Individuals also have reported problems such as cough, fatigue and breathing problems. There has been no evidence that specifically supports an allergy to carpet, but some people believe that it is possible. With new carpet, this is thought to be the result of breathing 4-phenylcyclohexene (4-PC), a chemical that is often used in the production of floor coverings. A reaction to an older carpet usually develops because of things such as mold, mites or dust trapped in its fibers, not because of the carpet itself.
An allergic reaction to carpet that has recently been installed typically does not last long. The low emission 4-PC chemical fumes usually dissipate within a few days. Some people are sensitive to the smell of the fumes, but others might not notice it at all. The severity of the reaction can vary depending on the materials used as well. Often, the padding and other accessories for installation will also emit fumes.
One of the best ways for a person who has a believed allergic reaction to carpet to avoid symptoms is to stay away from the newly carpeted area for a few days. The fumes can be cleared from the area more quickly with thorough ventilation, such as using fans and keeping windows and doors open. If a carpet is unrolled and aired out before installation, it can help avoid bringing some of the fumes inside. There also are low-emission carpets, padding and other accessories available for people who think that they have an allergy.
Some people are sensitive to things such as dust, mold and mites that can become trapped in old carpets, which can seem like an allergic reaction to carpet. Frequent vacuuming and proper room ventilation can reduce the symptoms by removing irritants from the atmosphere. There have been differing opinions about whether removing carpet can also help with symptoms. Some people believe that the carpet will increase the amount of irritants in a room. Others claim that carpet helps ease allergy suffering by removing irritants from the air and trapping them in its fibers.
If symptoms do not subside with avoidance or cleaning, traditional methods of treating environmental allergies can be used. This can include administration of antihistamines and itch cream. If breathing problems are severe, such as with asthma sufferers, an inhaler or other form of respiratory medication might be prescribed.
