History: I have been diagnosed with Eustachian Tube Dysfunction (ETD). It has been 28 days now, and my ear symptoms are feeling better than before. Current Medicine: For this, I have been taking Monticope tablet once daily for the last 14 days. New Symptoms (Side Effects): I am experiencing sleep paralysis (unable to move while waking up/sleeping). Continuous hand muscle twitching starting from last night. Feeling severely depressed or low mood (mood off). Since Monticope contains Montelukast, I am worried about these neuropsychiatric side effects. Since my ETD is improving, please suggest a safe alternative medicine or nasal spray to replace Monticope. Thank you.
