2 days ago, an elder sister came to the doctor for gynecological diseases and told me that I have been taking azithromycin tablets for a month, but the infection has not completely improved, and asked to continue taking azithromycin tablets prescribed for one month , so that the disease can be completely cured.

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.
So, how to take medicine correctly?
Taking medicines is not something we can take every day like our daily meals. We all know that medicines are used to treat diseases. Scientific medicine can treat diseases, but if it is abused, it will be counterproductive. Azithromycin dosage:
● For the treatment of sexually transmitted diseases caused by Chlamydia trachomatis or sensitive Neisseria gonorrhoeae, only a single oral dose of 1 gram is required. That is, you only need to take it once, 1 gram at a time. For example, if the content is 0.25 grams, then you need to take 4 capsules to achieve the therapeutic effect.
The treatment of other infections: Take 0.5 grams of medicine on the first day, (that is, 2 capsules), and take it every day on the 2nd to 5th day 0.25g or 0.5g, taken once a day for 3 consecutive days.
The dosage for children needs to be calculated according to the weight of the child, because the growth of children is not yet perfect, and they are still in the growth and development stage, and the resistance of various organs to some drugs will cause some damage .
◆ Treatment of otitis media and pneumonia: Day 1, calculated by body weight, per day The required dose per kilogram is 10 mg (the maximum amount cannot exceed 0.5 grams per day), Day 2~Day 5, the daily dosage is 5 per kg In milligrams, it only needs to be taken once a day. (The maximum amount per day should not exceed 0.25 grams.)
● Treatment of infantile pharyngitis and tonsillitis, calculated per kilogram 12 mg per kg (the daily amount should not exceed 0.5 g), it is enough to take it only once a day for 5 consecutive days, or follow the doctor’s advice.
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.
