Zithromax is an organic substance from the group of macrolides, a subclass of azalides. The antibiotic blocks the production of certain vital proteins by bacteria, which allows them to stop their growth and reproduction. Thus, this drug has a bacteriostatic rather than bactericidal effect. However, this does not mean that this drug is weaker than bactericidal antibiotics because stopping the growth of bacteria in most cases leads to the death of the stamm. By the way, in large doses, Zithromax provides a bactericidal effect.

  • streptococci;
  • staphylococci;

There are no data on cases of taking doses in larger quantities than recommended at a consultation with a specialist or in recommendations for use. Symptoms are similar to common side effects: dyspeptic disorders in the form of nausea, vomiting, pain in the stomach and intestines, as well as temporary reversible hearing loss. The treatment is symptomatic. A medication of a specific action that stops or decreases the effect of large doses taken (antidote) has not been developed. Dialysis is not used.

Drug interactions

  • Antacids (containing aluminum, magnesium) significantly reduce the absorption of azithromycin, so the drug should be taken at least 1 hour before or 2 hours after taking these drugs.
  • It does not bind to enzymes of the cytochrome P450 complex and, unlike macrolide antibiotics, no interaction with theophylline, terfenadine, carbamazepine, triazolam, digoxin has been observed.
  • Macrolides with concomitant use with cycloserine, indirect anticoagulants, methylprednisolone, felodipine and microsomal oxidation preparations (cyclosporine, hexobarbital, ergot alkaloids, valproic acid, disopyramide, bromocriptine, phenytoin inhibitor, peroxidation) while when using azalides, such an interaction has not been noted.
  • If co-administration with warfarin is necessary, it is recommended to carefully monitor the prothrombin time.
  • With the simultaneous administration of macrolides with ergotamine and dihydroergotamine, their toxic effects (vasospasm, dysesthesia) are possible.
  • Lincosamides weaken, and tetracycline and chloramphenicol enhance azithromycin effectiveness.
  • Pharmaceutically incompatible with heparin.
