Since you are still experiencing a cold, cough, and congestion in your Eustachian tube, it is best to consult your prescribing doctor before stopping or extending your medications. They can safely evaluate your progress and decide if you need to continue the Augmentin (amoxicillin/clavulanate), LCZ-Mont (levocetirizine/montelukast), and ear drops, or if a different approach is needed to clear the remaining mucus. In the meantime, staying hydrated and using steam inhalation can help soothe your airways and ease the pressure in your ears.

LCZ Mont treats allergies, not viral infections. Your current cold is likely viral, explaining why the medicine isn't working. You can stop it and switch to symptomatic relief. Use paracetamol for fever or aches, and steam inhalation or saline drops for congestion. Routine tests aren't needed yet, but if symptoms persist beyond a week or worsen, consult a doctor locally for a physical exam and possibly a CBC test. Ensure you get plenty of rest, drink warm fluids, and practice good hygiene.
