Points to note when using azithromycin
Many people know that some medicines need to be taken before or after meals or on an empty stomach. Such requirements are mainly based on the nature of the medicine to determine the time of taking the medicine.
● Azithromycin is generally taken 1 hour before or 2 hours after meals, because if you choose to take it with food, it will affect the absorption of azithromycin.
● Azithromycin should be used with caution in patients with hepatobiliary system diseases, because the excretion of azithromycin is mainly excreted through the hepatobiliary system, so it may cause damage to the liver and gallbladder.
● If you have allergic angioedema or skin reaction disease while taking it, you should stop taking the medicine immediately and go to the hospital in time.
According to literature, in 2013 the US FDA issued a warning, Azithromycin can cause abnormal electrical activity in the heart, causing fatal arrhythmias. Higher risk of QT prolongation, hypokalemia or hypomagnesemia, tachycardia, and addition of antiarrhythmic drugs.

How should azithromycin be used in the treatment of mycoplasma disease?
The treatment of mycoplasma infection with azithromycin depends on the type of mycoplasma and the site of infection. The course of treatment ranges from 1 to 3 weeks. For upper respiratory tract infection caused by Mycoplasma pneumoniae, the course of treatment is generally about 7 days. For lower respiratory tract infection caused by Mycoplasma pneumoniae, Such as bronchopneumonia and tracheitis, generally need to take about 2 weeks. Urinary tract infection caused by Ureaplasma urealyticum, Mycoplasma genitalium, Mycoplasma hominis, that is, mycoplasma infection transmitted through sex, generally requires more than 2 weeks of treatment. It is best to take it for about 3 weeks so that it can be effectively treated, and the recurrence rate will be relatively reduced. However, azithromycin has high drug resistance. If it is to treat mycoplasma infection in the genitourinary system, it is best not to choose azithromycin as the first choice. Antibiotic treatment.
