Nasal corticosteroids, antihistamines, oral decongestants, decongestant nasal sprays and montelukast treat mold allergies, according to Mayo Clinic. Immunotherapy and nasal lavage are also used to treat this condition.
There is no cure for mold allergies, but treatments ease symptoms, explains Mayo Clinic. Nasal corticosteroids such as fluticasone and mometasone treat and prevent inflammation caused by an upper respiratory mold allergy. Nasal corticosteroids can be used for long-term treatment but may have side effects such as nasal dryness and nosebleeds. Antihistamines such as loratadine and cetirizine treat runny nose, itching and sneezing caused by an allergic reaction. Antihistamine side effects include drowsiness, nasal dryness, dry mouth and bitter taste in the mouth.
Oral decongestants treat mold allergies, but people with high blood pressure should avoid this type of medication, warns Mayo Clinic. Decongestant nasal sprays such as oxymetazoline are a short-term treatment for mold allergy symptoms; side effects include insomnia, headache and nervousness. Montelukast is used when mold allergies are coupled with mild asthma or nasal sprays cannot be used, and immunotherapy is effective in treating certain types of mold allergies. Nasal lavage treats mold allergies by irrigating the nasal passages. The water used for nasal lavage should be sterile, distilled, or filtered with a filter that has a pore size of 1 micron or less.
