<s>[INST] I have had a chesty barking cough for about 6 weeks now, 3 weeks in i went to my doctor and he prescribed Amoxycillin antibiotics and a ventolin to help with breathing (i dont have athsma but he thought my throat was constricting due to al the coughing). i thought i was getting better for a while but then the cougChatDoctore back pretty much straight away. what should i do? [/INST] Hi, Welcome to Chat Doctor. If your cough has returned then most probably you are not responding to the antibiotic treatment as expected. You will need to change the antibiotics prescribed. I suggest you undergo a culture sensitivity of sputum and get appropriate antibiotics based on that test. You might have to take a bucolic which will soften the phlegm and help in reduction of cough. If your cough does not reduce even after 5 days of antibiotics, then you need to get a chest X-ray to rule out tubercular focus. Thanks. </s>
