Dear Friend.Dry cough
can have many reasons. Most commonly allergy
but for that montek LC would have helped you.
Sometimes, GERD (Gastro-Esophageal Reflux Disease) causes dry cough especially during the morning time.
Are you a smoker?
I would suggest you to take a combination of Pantoprazole
If it helps, its GERD.
you should get a chest x ray and haemogram with ESR.
