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.

I understand you are very concerned about your grandfather. While atorvastatin and Olmy D (olmesartan) can sometimes cause side effects like mild fatigue or dizziness from low blood pressure, his sudden extreme weakness, sweating, and shortness of breath after walking just a few steps are serious symptoms. These could indicate an underlying heart issue rather than just medication side effects. Please do not alter or stop his medications on your own. Because these symptoms require urgent evaluation, please seek immediate emergency medical care for him so a physician can evaluate his heart and safely adjust his treatment.

His symptoms of sudden weakness, shaking, and sweating could indeed be linked to his medications. Asthalin (salbutamol) can sometimes cause temporary shaking, sweating, or a fast heartbeat, especially after physical exertion. Montair (montelukast) is less likely to cause these specific symptoms. However, because these signs occur after walking just a few steps, they could also be related to an underlying heart condition or a drop in blood pressure. Since he is 80, it is best to have his doctor evaluate him promptly to ensure his safety and adjust his treatments if necessary.

It is generally not recommended to take Montair LC and Alex syrup together. Montair LC contains an antihistamine (levocetirizine), and Alex syrup also contains an antihistamine. Combining them can lead to duplicate therapy, which significantly increases the risk of side effects like excessive drowsiness, dizziness, and severe dry mouth. For your safety, it is best to use only one of these medications or consult your healthcare provider to find a safer, more targeted combination to relieve your throat symptoms. Staying well-hydrated can also help soothe your throat naturally.

Since your nasal endoscopy was normal?which is very reassuring?your ongoing ear pressure, crawling sensation, and jaw pain may not be sinus-related. Instead, they could stem from Eustachian tube dysfunction or Temporomandibular Joint (TMJ) issues, where jaw tension affects the ear nerves. Since medications like Montair LC and Avamys haven't fully resolved this, I gently recommend consulting your ENT specialist to evaluate your Eustachian tube directly, or a dental specialist to check for TMJ dysfunction. In the meantime, applying warm compresses to your jaw may offer some comforting relief.

Yes, taking Montair LC (which contains montelukast and levocetirizine) 12 hours before your Pulmonary Function Test (PFT) can affect the results. This medication helps relax your airways, which might make your lung function appear better than it typically is without treatment. To get the most accurate baseline assessment of your lungs, doctors usually recommend holding this medication for at least 24 hours before the test. Please don't worry, but do let your testing technician or doctor know that you took a dose 12 hours prior, so they can interpret your results accurately or safely reschedule if needed.
