Yes, it is generally safe to take Montair LC (which contains montelukast and levocetirizine) and Dolo 650 (paracetamol) together. They work differently and do not have any harmful interactions. The paracetamol in Dolo 650 will help soothe your sore throat and relieve pain, while Montair LC targets allergic irritation or congestion. Please take them as directed by your doctor, ideally after food. Sipping warm water and gargling with salt water can also provide great relief. If your symptoms persist for more than a few days or worsen, please consult your healthcare provider.

A clear chest X-ray is great news because it rules out serious lung infections. However, Montair LC (montelukast and levocetirizine) works by controlling underlying airway inflammation and allergies. When you stop the medication, this underlying sensitivity returns, triggering your cough again. This is common in conditions like cough-variant asthma or allergic bronchitis. Please don't worry, but do consult your doctor. They can help identify the root cause and guide you on how to safely manage or taper the medication.

Your symptoms of left-sided throat pain radiating to your ear and jaw could be related to conditions like temporomandibular joint (TMJ) issues, nerve irritation, or even acid reflux, which standard X-rays and swabs might miss. Montair LC (montelukast/levocetirizine) is primarily used for allergies and is unlikely to relieve this specific pain unless it is driven by allergic inflammation. Since your standard tests were clear, I highly recommend consulting an Ear, Nose, and Throat (ENT) specialist for a more detailed evaluation to help you find the right relief.

Since you are already taking Montair LC (which contains montelukast and levocetirizine), new or worsening generalized itching suggests your allergies might be active right now. While having allergic asthma doesn't automatically prevent you from getting the Covishield vaccine, it is safest to have a doctor evaluate your itching before you get the injection tomorrow. This ensures you aren't having an active, severe allergic reaction that could complicate your vaccination. Consult the medical officer at your vaccination center before getting the shot.

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.

Since your cold and breathing difficulties have lasted ten days despite taking Sero-flow, Montair LC, and doxycycline, it is very important to consult your doctor for a re-evaluation. Doxycycline is an antibiotic and won't treat viral infections, and your breathing issues may need an adjustment in your treatment plan. Please seek immediate medical care if you experience severe shortness of breath, chest pain, or a high fever. Rest up, stay hydrated, and let a healthcare professional take a closer look to help you feel better soon.
