Since he has a family history of allergies, creating an allergen-free bedroom is key. Try washing his bedding weekly in warm water, using a cool-mist humidifier, and elevating his head slightly with an extra pillow to ease breathing. Offering warm fluids before bed can also soothe his throat. Montek LC Kid, which contains montelukast and levocetirizine, is indeed helpful for allergic symptoms. However, please consult his pediatrician before restarting any medication to ensure it is still the right dosage for his current weight.

It is best not to give them a half tablet of adult Montek LC (montelukast/levocetirizine). Splitting combination tablets can result in an uneven dose, meaning your child might get too much or too little of the active ingredients. Children's bodies process medicines differently, and pediatric doses are carefully tailored for safety. I gently recommend consulting your pediatrician, who can prescribe the precise, child-friendly strength of montelukast/levocetirizine suited for an 11-year-old.

Yes, a long-term sinus infection can certainly cause the adenoid gland to swell as it fights off inflammation. I understand how exhausting it must be to still feel unwell after taking medications like Amoxicillin, Azithromycin, Zocef, Combiflam, and Montek LC. Since your throat pain and cold sensitivity persist, the inflammation may need a targeted approach, or the cause might be non-bacterial, such as allergies. Please consult an Ear, Nose, and Throat (ENT) specialist for a proper examination. In the meantime, try warm saline gargles, stay hydrated, and avoid cold air to soothe your throat.

This often happens because the underlying allergy triggers are still present, rather than a dependency on the medication itself. Please don't worry, this is quite common. To stop safely, it is best to consult your doctor. They can evaluate your triggers and may suggest temporarily using a steroid nasal spray or transitioning to a milder, single-ingredient antihistamine to ease the transition. Together, you can create a comfortable, step-by-step plan to manage your symptoms without relying long-term on this combination medication.

Moving to a colder climate can dry your nasal passages, worsening symptoms. For immediate comfort, try daily saline nasal rinses and use a bedroom humidifier. Since past treatments failed, you may benefit from daily prescription-strength generic steroid nasal sprays (like fluticasone) under a doctor's guidance. For a long-term solution, I highly recommend consulting an ENT specialist or allergist to discuss allergen immunotherapy (allergy shots), which can desensitize your body to triggers for lasting relief.

It is very reassuring that you have no fever, and your oxygen level (97%) and pulse (75) are completely normal. At 73, it is wise to be cautious, but a mild viral cold and cough often take 7 to 10 days to resolve, so three days without major improvement is quite common. Since you are already taking paracetamol and Montek LC (montelukast/levocetirizine), continue focusing on rest, warm fluids, and steam inhalation to soothe your throat. Please monitor your symptoms. If you develop any shortness of breath, chest pain, or a new fever, please consult your doctor promptly for a physical evaluation.
