My grandson has abad cough what do i need to do.?

More Info needed: Is your grandson an infant, child, teenager, or an adults. What other symptoms does he have? Is there a history of asthma? How is his breathing? If he is an infant and you feel nervous about it, consider taking him to an urgent care for immediate check by a physician.

Identify trigger: The way to approach a cough is to determine the trigger or cause of the cough. There are multiple potential reasons ranging from infections to allergies to asthma to a foreign body in the lungs or esophagus (food tube). A cough suppressant is not recommended except for an irritant cough when the primary reason has already been treated. It's best not to guess, but see a doctor.

Depends : Not enough info to answer. How old is your grandson. How long has he had this cough? Is he sick? When does it bother him. There are different ways of treating cough for different age groups, also depending on the cause. Feel free to write back giving more details then maybe we can offer some help to you.
