Hi,
Fiberglass is a multipurpose material used in the construction of buildings, automobiles, fabric and sporting goods. Fiberglass strands or dust can be easily inhaled. Mucous membranes in air passages are particularly sensitive to foreign particles. The inhaled particles can irritate these membranes, and, might cause "bronchitis-like symptoms" or discolored phlegm.
Health effects from exposure to fiberglass can be different depending on the fiber size and type of exposure. Larger fibers have been found to cause skin, eye and upper
respiratory tract irritation.
Airway irritation related to fiberglass can sometimes trigger
asthma symptoms in those previously diagnosed, potentially worsening his or her condition.
Long-term effects of exposure to fiber glass will also depend on the type of fiber and amount inhaled. As you've moved out of the source, symptoms have to wane off.
I also suggest consulting a pulmonologist who will examine the airway and will be able to decide the medication.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Prabhash Verma,
