Many drugs, especially those with hepatotoxicity, many people don't know how many days after taking them, they can't continue to take them. This often leads to liver damage. How many days and usage can azithromycin for injection be used at most? Next, I'd like to share my views with you.

How many days and usage can azithromycin for injection be used at most?

Azithromycin injection can be used for up to 7 days. Because the half-life of azithromycin is up to 48 hours, that is to say, the drug length is reduced by half after 2 days. If continuous infusion, for example, for 5 days, the drug concentration will continue to increase and increase by half every day. In this way, after 5 days, the drug concentration can be so large that it can damage the liver,

The scientific method is to take azithromycin orally after two days. Because the absorption of azithromycin orally is slower, the concentration of azithromycin increases more slowly. If you take azithromycin for less than 7 days, it will not damage the liver. If you want to continue taking azithromycin, you must stop taking azithromycin for more than two days. Azithromycin injection treatment effect is good.

Azithromycin is an azaendoester antibiotic. Its mechanism of action is to interfere with the synthesis of protein (without affecting the synthesis of nucleic acid) by binding with the subunit of 50s ribosome of sensitive microorganisms.

matters needing attention

In order to ensure the safety of drug use, it is suggested to do a drug sensitivity test before use and treat according to the doctor's advice. If the symptoms have been alleviated, azithromycin can be temporarily stopped or oral medicine can be used instead. The general treatment principle is that if it can be taken orally, it should not be injected. If it can be injected intramuscularly, intravenous injection is not needed.
