Hello, I have chronic pharyngitis. Everytime I feel cold the next day I develop sore throat. Usually the irritation is not that much.But sometimes the irritation increases and I am left with no choice but to take antibiotics. The last antibiotic I took was on 1-4 february 2017. This time today on Mar 14 I have severe irritation on my throat and I am thinking of taking antibiotics. My question is "Is it okay to take antibiotics after 1 month?" The antibiotic I am taking here is Azithromycin 500 mg.
