<s>[INST] I am 56yrs old female. Height 5ft 4inches ,weight 73 kg. I was suffering from a choking persistent cough.I have a history of asthma but had no problem for the last 5 years this time as the cough continued for three weeks I have been prescribed ondimont-lc for 14 days I stopped on the 14th day but there was a relapse and I have continued it from the 18th day .The excessive drowsiness and the mild trembling of my limbs is making every day work difficult. How long must I continue it?Does it need tapering off? [/INST] hello, thanks for your query, in my opinion u have got allergy induced cough , well tolerated to tab. odenent- lc. it's a prophylactic drug to prevent allergy or asthma. it should be taken 6-8 months, then slowly it should be tapered. if u feel sleepy with it u can go for ebast- m( ebastine+ montelukast one tab at bed time. all the best. take care. </s>
