From the Guidelines
Treatment for persistent cough and congestion due to mold exposure should prioritize removing the patient from the mold source and providing symptomatic relief, with first-line medications including antihistamines and nasal corticosteroids, as the most recent and highest quality evidence suggests that reducing exposure and alleviating symptoms are crucial for improving morbidity, mortality, and quality of life 1.
Identifying and Eliminating Mold Source
The most critical step in managing persistent cough and congestion due to mold exposure is identifying and eliminating the mold source through professional remediation to prevent ongoing exposure and symptoms. This approach is supported by guidelines that emphasize the importance of reducing mold exposure, especially in highly immunocompromised patients 1.
Symptomatic Relief
For symptomatic relief, medications such as antihistamines (e.g., loratadine 10mg daily or cetirizine 10mg daily) and nasal corticosteroids (e.g., fluticasone 1-2 sprays per nostril daily) can be used to reduce allergic responses and decrease inflammation. Additionally, saline nasal irrigation with devices like a neti pot can help clear mucus and irritants.
Managing Cough and Asthma-like Symptoms
For cough, dextromethorphan (15-30mg every 4-6 hours) may provide relief. Patients with asthma-like symptoms may benefit from bronchodilators such as albuterol (2 puffs every 4-6 hours as needed). These treatments work by reducing the inflammatory response triggered by mold spores in the respiratory system.
Further Evaluation
If symptoms persist despite treatment and mold removal, further evaluation for possible complications like fungal infection or hypersensitivity pneumonitis may be necessary. This is particularly important as the evidence suggests that chronic exposure to mold can lead to more severe respiratory conditions 1.
Key Considerations
- Mold Exposure Reduction: Reducing exposure to mold is crucial, and patients should avoid activities that increase exposure, such as gardening or spreading mulch, especially if they are immunocompromised 1.
- Symptomatic Treatment: Symptomatic treatment should focus on alleviating cough, congestion, and allergic responses.
- Professional Remediation: Professional remediation of the mold source is essential to prevent ongoing exposure and symptoms.
- Monitoring and Follow-Up: Patients should be monitored for the resolution of symptoms and potential complications, with follow-up evaluations as necessary.

From the Research
Treatment Options for Persistent Cough and Congestion due to Mold Exposure
- The treatment for a patient with persistent cough and congestion due to mold exposure involves addressing the underlying allergic response and managing symptoms 2, 3.
- Immunotherapy for mold allergy is a potential treatment option, although most studies focus on Alternaria and Cladosporium, and there is a lack of randomized placebo-controlled trials 2, 4.
- The medical effects of mold exposure can include asthma, allergic rhinitis, and hypersensitivity pneumonitis, which should be considered when evaluating and treating patients 3.
- For patients with post-infectious persistent cough, therapeutic options are limited, but may include addressing underlying conditions such as upper airway cough syndrome, gastroesophageal reflux disease, or asthma 5, 6.
- Evaluation of patients with chronic cough should include clinical assessment, spirometry if indicated, and empiric treatment, with consideration of potential causes such as environmental triggers, tobacco use, or chronic obstructive pulmonary disease 6.
Management of Mold Exposure
- Removing the patient from the mold-exposed environment is essential to prevent further exposure and alleviate symptoms 3.
- Treatment of underlying conditions, such as allergic rhinitis or asthma, can help manage symptoms and improve quality of life 2, 4.
- Patients with refractory chronic cough may require referral to a specialist, such as a pulmonologist or otolaryngologist, for further evaluation and treatment 6.
