Hi welcome to Health care magic forum, You are using Amtas AT since 2 years , now you are getting
cough, so it might not be due to the side effect of the drug.
Of course cough is the side effect of amlodepine, but it need not be there with everybody, some people only get it as side effect. If you are having cough sinse 2 years, then we can consider as a side effect in your case.
Your cough could be allergic or due to infection. I advise you to consult a physician for diagnosis and treatment. You may need to have blood work,
x ray chest, etc, to find out the diagnosis.
Besides i advise you to follow some diet recommendations as avoid fruits, juices, cooling things, sea foods, and brinjal as these tend to increase the existing
allergy, and they are allergens by themselves.
Wishing for a quick recovery and thanks for calling.
