Azithromycin
Azitro is an antibiotic belonging to a group called macrolides. It is used to treat infections caused by bacteria.
The medicine is usually prescribed to treat:
infections in the chest, such as chronic bronchitis, pneumonia;
infections of the tonsils, throat, and sinuses;
ear infections (acute otitis media);
skin and soft tissue infections (except for burn wound infections);
infections of the urethra and cervix caused by chlamydia.
azithromycin;
erythromycin;
any other macrolide or ketolide antibiotic;
any of the other ingredients of this medicine (listed in section 6).
Before starting to take Azitro, you should discuss it with your doctor or pharmacist:
sometimes, as a result of taking Azitro, allergic reactions (itching, rash) may occur. However, if a serious allergic reaction occurs, the patient will quickly develop swelling of the face and throat (angioedema), which causes a feeling of shortness of breath, or a sudden very bad feeling (anaphylaxis). High fever, skin rash, blisters on the skin, peeling of the skin, joint pain, and (or) eye inflammation (Stevens-Johnson syndrome, toxic epidermal necrolysis, DRESS syndrome, or acute generalized exanthematous pustulosis) may also be symptoms of severe allergic reactions.
if the patient has liver function disorders, they should inform their doctor before starting to take Azitro. During the use of Azitro, cases of very severe liver inflammation have occurred, which can potentially lead to life-threatening liver dysfunction. The doctor should be informed immediately if the patient experiences such symptoms as rapidly progressing physical weakness (asthenia), accompanied by jaundice, dark urine, tendency to bleed, and decreased level of consciousness (hepatic encephalopathy). The doctor will assess liver function and probably advise the patient to stop taking Azitro.
kidney function disorders: if the patient has severe kidney function disorders, a dose change may be necessary;
neurological or psychiatric disorders;
a specific type of muscle weakness called myasthenia
if the patient has had infections with pathogens resistant to azithromycin, erythromycin, lincosamide, and (or) methicillin-resistant staphylococci (possibility of cross-resistance).
Azithromycin may increase the risk of heart rhythm disturbances, so if the patient has any of the following heart disorders, they should inform their doctor before starting to take the medicine:
heart disorders, such as heart failure, very slow heart rate, irregular heart rate, or abnormal electrocardiogram (ECG) readings, known as "prolonged QT interval";
low potassium or magnesium levels in the blood.
If the patient experiences diarrhea or loose stools during or after treatment, they should immediatelyinform their doctor. No anti-diarrheal medicine should be taken without consulting a doctor first. If the diarrhea persists, the patient should tell their doctor.
The patient should inform their doctor if:
they notice an exacerbation of symptoms during treatment or soon after its completion [possibility of superinfections and (or) resistance].
Azithromycin is not suitable for the treatment of severe infections where rapid achievement of high blood antibiotic levels is necessary.
In case of difficulties with swallowing tablets, for example, in young children, the use of Azitro suspension may be considered. Azitro tablets are not suitable for children with a body weight below 45 kg.
If, after administration of the medicine to a newborn (under 6 weeks of age), vomiting or irritability during feeding occurs, the doctor should be informed immediately.
The patient should tell their doctor or pharmacist about all medicines they are currently taking or have recently taken, as well as those they plan to take, including those available without a prescription. This is especially important before starting treatment with this medicine.
Theophylline(used to treat asthma): the effect of theophylline may be enhanced.
Warfarinor other similar anticoagulant medicines: concurrent use may increase the risk of bleeding.
Ergotamine, dihydroergotamine(used to treat migraines): ergotism (with tingling of the limbs, painful muscle spasms, and gangrene of the hands and feet due to poor blood circulation) is possible. Therefore, combined treatment is not recommended.
Cyclosporin(used to suppress the immune system in the prevention and treatment of organ or bone marrow transplant rejection): if combined treatment is necessary, the doctor will recommend regular blood tests and may adjust the dose of the medicine.
Digoxin(a medicine used in heart failure): the level of digoxin in the blood may increase. The doctor will recommend checking this level.
Colchicine(used to treat gout and familial Mediterranean fever): it is necessary to check the level of colchicine in the blood more frequently and, if necessary, adjust the dose of colchicine.
Antacids (used to neutralize stomach acid): see section 3.
Cisapride(used to treat stomach disorders), terfenadine(used to treat hay fever), pimozide(used to treat certain mental illnesses), citalopram(used to treat depression), fluoroquinolones(antibiotics used to treat bacterial infections, e.g., moxifloxacin and levofloxacin): concurrent use with azithromycin may cause heart rhythm disturbances, so combined treatment is not recommended.
Medicines used to treat irregular heart rhythms (so-called anti-arrhythmic medicines).
Zidovudine(used to treat HIV infections): concurrent use may increase the risk of side effects.
Nelfinavir(used to treat HIV infections): concurrent use may enhance the side effects of azithromycin.
Alfentanil(used for anesthesia) or astemizole(used to treat hay fever): concurrent use with azithromycin may enhance the effect of these medicines.
Rifabutin(used to treat tuberculosis): the doctor may recommend regular blood tests and check the level of the medicine in the blood.
Statins (such as atorvastatin, used to reduce blood lipid levels): concurrent use with azithromycin may cause muscle disorders.
Some medicines (such as hydroxychloroquine) that are known to cause heart rhythm disturbances, e.g., QT interval prolongation detected in an electrocardiogram: concurrent use may increase the risk of arrhythmia.
Anticoagulant medicines from the coumarin group (blood thinners that prevent blood clots); although it seems that Azitro does not affect the blood-thinning effect of coumarin group medicines, it may be necessary to check blood clotting more frequently and adjust the dose of the medicine.
The tablets can be taken independently of meals.
If the patient is pregnant or breastfeeding, thinks they may be pregnant, or plans to have a child, they should consult their doctor or pharmacist before taking this medicine.
Pregnancy
The doctor will decide whether the patient should take this medicine during pregnancy, only after weighing the benefits and potential risks.

It has been reported that azithromycin is excreted into human milk. No serious side effects of azithromycin have been observed in infants.

If the patient has previously been diagnosed with intolerance to some sugars, they should contact their doctor before taking the medicine.
This medicine contains less than 1 mmol (23 mg) of sodium per dose, which means the medicine is considered "sodium-free".

If possible, the patient should take the tablets or the packaging of the medicine with them and show it to the doctor.
