Your constant cough, blocked nose, and throat infections suggest underlying allergic rhinitis or sinusitis, where post-nasal drip continually irritates your throat. For long-term relief, we need to address the root cause, potentially through allergy testing to identify specific triggers. While continuing your mometasone nasal spray and montelukast/fexofenadine helps manage symptoms, a specialist like an ENT doctor or allergist can help design a personalized, long-term plan, which might include allergen immunotherapy. Please consult a doctor for a comprehensive evaluation.

Sneezing, itching, and watery eyes can be lessened by antihistamine eye drops and oral antihistamines such as cetirizine or loratadine. Keep windows closed, stay away from allergens, and use a saline nasal spray to help clear your nose.

Eltroxin (levothyroxine) is managing your hormone levels, persistent fatigue and weight gain can sometimes be linked to vitamin deficiencies or metabolic changes. Regarding Febutaz 40 (febuxostat), starting this medication can occasionally cause temporary drowsiness or fatigue. Your burning eyes might be related to dry eyes, which is common in thyroid conditions, or a mild reaction to the new medication. I gently reassure you that these are manageable; please discuss these symptoms with your doctor to explore vitamin checks or adjust your treatment safely.

Since medications like Sopramez, Montair FX, and Zyrcold haven't brought relief, it is important to consult a pulmonologist or an ENT specialist for a detailed evaluation. A chronic cough can sometimes stem from underlying issues like cough-variant asthma, persistent post-nasal drip, or acid reflux that may require different targeted treatments. For now, please stay well-hydrated with warm fluids, consider using a cool-mist humidifier in your bedroom, and elevate your head slightly while sleeping. Please avoid starting any new medications without a doctor's guidance.

But please do not start this combination of medications without a doctor's evaluation. Taking Azithromycin (an antibiotic) and Ivermectin without a confirmed diagnosis is not recommended and won't help if it is a viral illness. Montair FX (montelukast and fexofenadine) and Alex SF syrup manage allergies and cough, while Pantodac DSR (pantoprazole and domperidone) is for acidity. Since your fever and chills have lasted 5 to 6 days, it is safest to see a doctor for a proper diagnosis and a tailored treatment plan.

Since you have not found relief with medications like Montair Fx (montelukast/fexofenadine), antibiotics like doxycycline and azithromycin, or Zerodol S, consulting an Ear, Nose, and Throat (ENT) specialist is indeed your best next step. They can examine your nasal passages to rule out conditions like nasal polyps, a deviated septum, or chronic allergies, and help tailor a safe, effective treatment plan for you. Please rest assured, you are taking the right steps toward feeling better.
