Help Please! My Son's Doctor Suspects He's Got Pneumonia And

Help please!

My son's doctor suspects he's got pneumonia and he was prescribed Salbutamol Guaifenesin which is an expectorant and an antibiotic Co-Amoxiclav. Today is the third day he's been feeling sick with asthma and wheezing.

The fever comes and goes. When we got home from the clinic, I noticed he's become very sleepy. He complained of neck pain and a headache.

I'm very worried. Do you think the prescription is correct? I'm afraid the doctor is missing something.

Help please,
Jenny
