I am currently taking Azythromycin for a respiratory infection today was my first dose about 5 and a half hours ago. i am now suffering from a horrible headache, watery diarrhea, my heart rate is high, i have a pain in my side near my stomach, and i feel extremely cold.
HI, thanks for using Chat Doctor Antibiotics, like all medications, can be associated with a possible side effects. Azithromycin can be associated gastrointestinal side effects such as abdominal pain, vomiting, diarrhea. The increased heart rate would be due to the infection and also related to the fluid loss due to the diarrhea. If you are unable to tolerate the effect of the medication, then you may want to consult your doctor. I hope this helps
