If you have a mold allergy, your immune system overreacts when you breathe in mold spores. A mold allergy can make you cough, make your eyes itch and cause other symptoms that make you miserable. In some people, mold allergy is linked to asthma and exposure causes restricted breathing and other airway symptoms.
If you have a mold allergy, the best defense is to reduce your exposure to the types of mold that cause your reaction. Medications can help keep mold allergy reactions under control.
