Zithromax: Antibiotic to Treat Bacterial Infections
Zithromax (azithromycin) is an antibiotic that fights bacteria. It is used to treat many different types of infections caused by bacteria.
What is it used to treat?
The medicine is used for infectious processes provoked by microbes sensitive to this antibiotic:
- infections of the skin, soft tissues (erysipelas, infected dermatosis, acne, impetigo);
- borreliosis (Lyme disease) at the initial stage – erythema migrans;
- infections of the ENT organs (laryngitis, pharyngitis, sinusitis, tonsillitis, otitis media, rhinitis, tracheitis);
- urinary tract infections, incl. chlamydial.
How does it work?
Azithromycin is an antibiotic of the macrolide group with a bacteriostatic effect (inhibits the growth of pathogenic microorganisms). It is active against a wide variety of microbes. The mechanism of action is associated with the suppression of protein production in the cells of the microbe. In high concentrations, it can have a bactericidal (killing microbes) effect.
Microorganisms susceptible to this antibiotic: gram-negative aerobes (Neisseria gonorrhoeae, Moraxella catarrhalis, Haemophilus parainfluenzae, Legionella pneumophila, Haemophilus influenzae, Pasteurella multocida), gram-positive aerobes (Staphylococcus aureus, S. pneumococcus aureus) spp., Clostridium perfringens, Porphyriomonas spp.), others (Chlamydia phneumoniae, Chlamydia trachomatis, Chlamydia psittaci, Mycoplasma hominis, Mycoplasma pneumoniae, Borrelia burgdorferi).
Microbes capable of developing resistance to this antibiotic: gram-positive aerobes (penicillin-resistant Streptococcus pneumoniae).
Azithromycin-resistant microorganisms: gram-positive aerobes (Staphylococci, Enterococcus faecalis), Bacteroides fragilis.
Is Zithromax a strong antibiotic?
Azithromycin is an antibiotic in the macrolides class. The antibiotic is quite strong, so you’d better take probiotics after a course of this medicine. In such a tandem, no viruses and bacteria can live in your body for a long time.
Why azithromycin is given for 3 days?
Because of the pharmacokinetic profile, it is possible to administer azithromycin in a once-daily dose for 3 days. Azithromycin 3-day dose pack is used to treat many different types of infections caused by bacteria, including infections of the lungs, sinus, throat, tonsils, skin, urinary tract, cervix, or genitals.

How long does this antibiotic stay in your system?
The medicine will be in your system for around 15.5 days, after the last dose. It has an elimination half-life of 68 hours. The prolonged terminal half-life is thought to be due to extensive uptake and subsequent release of drug from tissues.

This antibiotic is excreted in milk, and therefore it is not used during breastfeeding.
Can you drink alcohol with Zithromax?
You cannot combine it with alcoholic products. Alcohol has a detrimental effect on the pharmacological properties of the drug. It slows down metabolism, changes the drug concentration and helps infectious diseases develop due to a decrease in the bioavailability of the active substance. In addition, alcohol provokes side effects.
What drugs interact with azithromycin?
Azithromycin is metabolized in the liver. It can interact with other drugs that also enter the liver. Scientists have not yet explored all possible interactions. Azithromycin likely interacts with some blood-thinning medications, heart medications, asthma medications, and other antibiotics. Make sure your doctor is informed about all medications and supplements you are taking.
Your doctor will likely need to monitor you closely if you are taking azithromycin and the protease inhibitor ritonavir.
Acid neutralizers (antacids) with aluminum or magnesium can reduce blood levels of azithromycin. Do not take antacids at the same time as azithromycin.
