I have been suffering from cough and wheezing since 2 years . I have been suggested by a doctor to take allegra M tablets. It gives me relief if i take tablet everyday. Otherwise i start coughing and wheezing starts which results in sleepless nights and breathing becomes tough. Now i am
pregnant. I am still using the tablets and worried if it would effect my pregnancy. I need a permanent cure to this as soon as possible. Please advise.
