Since Montair LC (which contains levocetirizine and montelukast) and steam inhalation aren't helping, your symptoms might be due to a different type of nasal sensitivity or persistent inflammation rather than a simple allergy. I recommend consulting an ENT specialist or allergist. They can help identify specific triggers and might suggest alternative options, such as prescription nasal sprays, to target the inflammation directly.

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.

Please be reassured that a TSH of 7.5 is mildly elevated, but it is not dangerously high. It suggests your thyroid is slightly underactive. While thyroid issues can sometimes cause dry skin, your recurring rashes for three months warrant a closer look. Your medications, Montair LC (montelukast and levocetirizine) and cetirizine, are excellent for managing allergy symptoms, but they treat the symptoms rather than the root cause. I highly recommend consulting your doctor to evaluate both your thyroid levels and the exact cause of your skin rashes to find a tailored, long-term solution.

You may take an antihistamine, such as cetirizine or loratadine, to help reduce sneezing, a runny nose, and watery eyes. If these do not provide relief, your doctor may prescribe a stronger antihistamine, a nasal steroid spray, or a combination treatment. Please see your doctor if symptoms persist for more than a week or worsen.

It is crucial not to share medications, especially since your mother has diabetes. While Dolopar 650 (paracetamol), Montair LC (montelukast and levocetirizine), and Zincovit are generally safe, Voveran SR 100 (diclofenac) should be avoided as it can adversely affect kidney function, a key concern in diabetes. Azithromycin, an antibiotic, is not helpful for viral COVID-19 unless a secondary bacterial infection is confirmed. Since infections can cause blood sugar levels to fluctuate, please monitor her glucose and oxygen levels closely. Please consult a doctor immediately for a personalized prescription tailored to her specific health needs.

For these symptoms, Cheston Cold (containing cetirizine, phenylephrine, and paracetamol) is generally more suitable as it helps relieve congestion and common cold symptoms. Montair LC (containing levocetirizine and montelukast) is typically prescribed for allergic rhinitis and asthma, rather than a standard cold. Since you also have a cough, it is important to identify its cause to treat it effectively. Please rest well and stay hydrated. I highly recommend consulting a healthcare professional for a personalized evaluation to ensure you get the safest and most effective treatment.
