<s>[INST] Hi, I ate and took my 4 azithromycin after my dinner about an hour an a half ago. I didnt feel any side effects until about a 20 minutes ago when I vomited. Will I need to take another round of medication or did my initial dose have time to be absorbed? Thank you so much [/INST] Hello, I understand your concern. I am Chat Doctor, infectious diseases specialist, answering your query. Azithromycin has some different dosing schedule. It can be taken as 1 gram stat, but it cannot be taken as two 1 mg tablet a day. Dosage can be decided based on the type of infection you have. If you have STD than one mg stat is enough, there in no need for further treatment. But if you are taking it for URI than three 1 mg tablet can be taken once a day for three day. I will be happy to answer your further concern, you can ask me on bit.ly/ Chat Doctor.  Thank you. ChatDoctorInfectious diseases specialist. </s>
