While mild body aches and a low-grade fever can be typical side effects of Covaxin, a high fever of 102?F accompanied by a runny nose, cough, and itchy throat strongly points toward a viral infection like COVID-19 or the flu, rather than a vaccine reaction or smoke allergy alone. Your medications, Montair LC (levocetirizine/montelukast) and Dolo 650 (paracetamol), are helpful for managing these allergy symptoms, fever, and body aches. Please rest, stay well-hydrated, isolate as a precaution, and consult a doctor or get tested for COVID-19 to ensure you receive the right care.

It is reassuring that your husband is feeling better after taking Dolo 650, Montair LC, and Azithromycin 500. A lingering dry cough is very common after respiratory infections as the airways remain sensitive and take time to heal. Taking a simple COVID-19 test is a safe and reasonable step to rule it out. However, a chest CT scan is unnecessary right now unless he develops severe symptoms like shortness of breath, chest pain, or a recurring fever. For now, keep him hydrated with warm fluids and try steam inhalation. Please consult his doctor if the cough worsens or does not improve soon.

Since Calosoft (calamine), Montair (montelukast), and Ascorbic D (vitamin C and D) have not fully resolved the issue, it is highly recommended to consult a pediatrician or pediatric dermatologist for a re-evaluation. Persistent rashes in a toddler can stem from various causes like eczema or specific allergies that need targeted treatment. Please be reassured; a specialist can safely examine his skin, find the exact cause, and guide you toward the right, effective therapy to help his skin heal comfortably.

Since your symptoms started with a cold and cough and your COVID-19 test is negative, this is likely a viral infection. Antibiotics only treat bacterial infections and will not help a virus. Because some antibiotics can interact with your antidepressants, it is very important not to self-medicate. You can continue taking Montair LC to help with your cold and cough symptoms. For your sore throat, try warm salt-water gargles and staying hydrated. Please consult your doctor to safely evaluate your symptoms before starting any new medication.

Calpol (paracetamol) is generally considered safe during pregnancy to help relieve pain and fever, but please use the lowest dose for the shortest time needed. However, Montair LC (levocetirizine and montelukast) should be avoided during your first trimester unless specifically prescribed by your obstetrician. I highly recommend consulting your doctor before taking Montair LC or if your symptoms worsen. For now, please prioritize resting and staying well-hydrated.

Montair LC (Montelukast + Levocetirizine) is generally safe for daily use under medical supervision for allergic conditions. However, your symptoms returning suggest that the root cause of your cough, such as cough-variant asthma, post-nasal drip, or acid reflux, is not fully controlled. Relying on this medication long-term without a definitive diagnosis is not recommended. I advise consulting a pulmonologist for evaluation, possibly including a spirometry test. Depending on the diagnosis, safer long-term alternative medications, such as inhaled corticosteroids, may be prescribed to target the inflammation directly. Please do not change your treatment plan without medical advice.
