Thanks for writing to health care magic.
I can understand your concern.
Yes you should consult your doctor. This is because even after 7 days of antibiotic treatment there is no improvement. Other diagnosis should be considered. There are several causes for cough
Monitor for the following in a child with cough.
1. Rapid breathing.
2. Chest indrawing while breathing.
3. Abnormal noise while breathing.
4. Nasal flaring
5. Bluish discoloration of fingers (cyanosis
6. Irritability or lethargy
If your child has any of these you should consult your doctor immediately
Continue to ask further queries as required.
Hope this helps.
