Antihistamines such as cetirizine or loratadine can help reduce swelling and sneezing associated with cold allergies, and nasal saline sprays can assist remove congestion. To naturally lessen symptoms, stay away from irritants, keep your living space dust-free, and drink enough of water.

Since your lung function tests and IgE levels are normal, and medications like Montair FX, benzonatate, and levocloperastine haven't helped, we can look beyond typical asthma or allergies. A very common trigger for nocturnal coughs is gastroesophageal reflux (GERD) or 'silent reflux,' where stomach acid irritates your throat when lying flat. Another possibility is non-allergic post-nasal drip. I highly recommend discussing these potential causes with your doctor, who may suggest a trial of acid-reducing medication or a nasal spray. Raising your pillow slightly might also offer some comfort.

Developing a worsening fever, blocked nose, and one-sided headache after starting Montair FX and Azilide suggests your symptoms might be progressing, possibly into a sinus infection. It is very important to contact your prescribing doctor for a re-evaluation, as your treatment plan may need to be adjusted. In the meantime, please rest, stay well-hydrated, and try steam inhalation to help ease the nasal congestion. If you experience high fever, stiff neck, or severe, worsening pain, please seek medical attention right away.

Typically, once you start your prescribed antibiotic, along with Montair FX (montelukast/fexofenadine) and Deriphyllin (theophylline/etofylline) to ease your breathing, you should begin to feel better. A low-grade fever usually starts to subside within 48 to 72 hours of starting effective antibiotic treatment. Please ensure you rest, stay well-hydrated, and take the medications exactly as prescribed. If your fever does not improve after three days, or if you experience shortness of breath, please contact your doctor promptly to ensure you are on the right path to recovery.

Headaches can sometimes occur with nasal sprays, often due to the spraying technique. When using your spray, try pointing the nozzle slightly outward toward your ears rather than straight up or toward the middle wall of your nose, as this reduces local irritation. Also, make sure to stay well-hydrated. Since this was prescribed alongside Montair FX, please consult your doctor before stopping. They can easily review your technique or adjust your treatment to a more comfortable option.

Montair FX (montelukast and fexofenadine), Doxy 100 (doxycycline), Brozedex syrup, or azithromycin?contain sulfa. They are safe to take regarding a sulfa allergy. However, combining two antibiotics like doxycycline and azithromycin is unusual for a COVID-19 cough and can cause stomach discomfort. I highly recommend consulting their doctor to confirm if both antibiotics are necessary. Please ensure they stay well-hydrated and get plenty of rest.
