A severe wet cough with a runny nose often suggests a respiratory infection or allergy. You can try staying well-hydrated, resting, and using a humidifier to ease symptoms. Over-the-counter antihistamines like fexofenadine (found in Allegra 120 mg) may help if allergies are suspected, but since your cough is severe, it’s important to see a doctor for a proper evaluation and treatment.

What you can do now:

• Drink plenty of fluids and rest.
• Use saline nasal sprays or steam inhalation to relieve nasal congestion.
• Avoid irritants like smoke or strong perfumes.

When to see a doctor urgently:

• If you develop high fever, difficulty breathing, chest pain, or coughing up blood.
• If symptoms worsen or do not improve in a few days.

Please consult a pulmonologist or an ENT (ear, nose, and throat) specialist to get an accurate diagnosis and appropriate treatment. If symptoms become severe or you have trouble breathing, seek emergency care immediately.To narrow down potential causes, we will need some more information.I understand you have a severe wet cough and a runny nose.
