<s>[INST] hello sir/mam.... i have an allergy since a year... frequent cold, sneezing ... so i went to ent specialist , he prescibed me tab montek-LC, so after 2-3 days my cold , cough, sneezing is gone.... but after a week, i have having severse stomach pain, digestion problem and even getting more and more sleep day time.... so is it the side effect of tab Montek LC or wat... ?? [/INST] HiT hanks for your queries gastric irritation occurs in case of montelukast after prolonged use and probably that is causing your stomach pain and digestion problem and sleepiness probably is occurring from levocetrizine component of the Monteagle medicine. So if your symptoms are well controlled now you can omit this Chat Doctor. Better to go for local application of elastane fluticasone nasal spray now after consulting your doctor. For stomach pain you need to take local anesthetic gel like machine gel for symptomatic receive and pantoprazole tablets for healing of the erosion if any by Monteagle. Thank you. </s>
