Before Using This Medicine
It is essential to inform your doctor about the following:
Any allergies you have, including allergies to this medication, its components, or other substances. Be sure to describe the allergic reaction and its symptoms.
If you have previously experienced liver problems or jaundice (yellowing of the skin or eyes) while taking this medication.
Certain health conditions, such as:
+ Abnormal heart rhythms, including a prolonged QTc interval on an electrocardiogram (ECG) or other irregular heartbeats.
+ Slow heartbeat or low levels of potassium or magnesium in your blood.
+ Heart failure, also known as a weak heart.
+ A history of torsades de pointes, a specific type of abnormal heartbeat.
If you are taking any medications that can cause abnormal heart rhythms, particularly those that prolong the QT interval. There are many medications that can have this effect, so it is crucial to consult with your doctor or pharmacist if you are unsure.
This is not an exhaustive list of all potential interactions or health problems that may be relevant to this medication. Therefore, it is vital to:
Inform your doctor and pharmacist about all the medications you are taking, including prescription and over-the-counter drugs, natural products, and vitamins.
Discuss all your health problems with your doctor to ensure it is safe to take this medication.
* Never start, stop, or change the dose of any medication without first consulting your doctor.
Precautions & Cautions
It is essential to inform all your healthcare providers, including doctors, nurses, pharmacists, and dentists, that you are taking this medication. Adhere to the prescribed duration of treatment, as prolonged use may increase the risk of a second infection.
Severe Heart Rhythm Changes
This medication can cause severe heart rhythm changes, including prolonged QT interval, which can be life-threatening or fatal. If you have any questions or concerns, consult your doctor.
Myasthenia Gravis
If you have myasthenia gravis, discuss your treatment with your doctor. Monitor your symptoms closely, and contact your doctor if they worsen. Additionally, be aware that signs of myasthenia gravis, such as new or worsening muscle weakness, difficulty chewing or swallowing, breathing problems, droopy eyelids, or changes in vision (e.g., blurred vision or double vision), can occur in people with or without a history of the condition. Seek immediate medical attention if you experience any of these symptoms.
Special Considerations for Older Adults
If you are 65 years or older, use this medication with caution, as you may be more susceptible to side effects.
Pregnancy and Breast-Feeding
If you are pregnant, plan to become pregnant, or are breast-feeding, consult your doctor to discuss the potential benefits and risks to you and your baby.
Newborns
In newborns taking this medication, a severe stomach problem can occur. If your child vomits or becomes irritable during feeding, contact your doctor immediately.
Overdose Information
Overdose Symptoms:
- Severe nausea
- Vomiting
- Diarrhea
- Hearing loss (reversible)
- Severe abdominal pain
What to Do:
Seek immediate medical attention or call a poison control center (1-800-222-1222). Treatment is symptomatic and supportive.
Drug Interactions
Major Interactions
- QT-prolonging drugs (e.g., Class IA and III antiarrhythmics, cisapride, pimozide, some antipsychotics, tricyclic antidepressants, fluoroquinolones): Increased risk of QT prolongation and Torsades de Pointes.
- Warfarin: Increased anticoagulant effect (monitor INR).
- Nelfinavir: Significantly increases azithromycin serum concentrations (no dose adjustment needed for azithromycin, but monitor for adverse effects).
- Antacids containing aluminum or magnesium: Decreased peak serum levels of azithromycin (administer azithromycin at least 2 hours before or after antacids).
Moderate Interactions
- Digoxin: Increased digoxin levels (monitor digoxin levels).
- Cyclosporine: Increased cyclosporine levels (monitor cyclosporine levels).
- Ergot alkaloids (e.g., ergotamine, dihydroergotamine): Potential for acute ergotism (vasospasm and dysesthesia). Avoid concomitant use.
- Statins (e.g., simvastatin, lovastatin): Increased risk of myopathy/rhabdomyolysis (though less pronounced than with other macrolides like erythromycin).
Minor Interactions
- Zidovudine: Increased zidovudine phosphorylation to its active metabolite in peripheral blood mononuclear cells (clinical significance uncertain).
Monitoring
Baseline Monitoring
Rationale: To confirm susceptibility of the causative pathogen, especially for severe infections or treatment failures.
Timing: Prior to initiation of therapy, if clinically indicated.
Rationale: Consider for patients with known QT prolongation, risk factors for QT prolongation (e.g., uncorrected hypokalemia/hypomagnesemia, bradycardia, concomitant QT-prolonging drugs, significant heart disease).
Timing: Prior to initiation of therapy.
Routine Monitoring
Frequency: Daily during therapy, then as needed
Target: Resolution of signs and symptoms of infection
Action Threshold: Lack of improvement or worsening symptoms may indicate treatment failure, resistance, or alternative diagnosis.
Frequency: Daily during and after therapy
Target: Absence of new or worsening symptoms
Action Threshold: Onset of severe diarrhea, abdominal pain, fever, or oral/vaginal candidiasis requires investigation and appropriate management.
Frequency: Not routinely required for short courses; consider for prolonged use or in patients with pre-existing hepatic impairment.
Target: Within normal limits or stable baseline
Action Threshold: Significant elevation may warrant discontinuation.
Symptom Monitoring
- Diarrhea (especially severe or bloody)
- Abdominal pain
- Nausea/Vomiting
- Rash or itching
- Signs of allergic reaction (e.g., swelling of face/throat, difficulty breathing)
- Yellowing of skin or eyes (jaundice)
- Dark urine
- Light-colored stools
- Unusual tiredness or weakness
- Palpitations or irregular heartbeat
- Dizziness or fainting
Special Patient Groups
Pregnancy
Category B. Studies in animals have shown no evidence of harm to the fetus. Adequate and well-controlled studies in pregnant women are lacking, but human experience suggests no increased risk of congenital anomalies. Generally considered safe when clearly needed.
Trimester-Specific Risks:
Lactation
L3 (Moderately Safe). Azithromycin is excreted into breast milk in small amounts. While generally considered compatible with breastfeeding, monitor breastfed infants for potential adverse effects such as diarrhea, vomiting, or rash. Consider alternative if infant is premature or has underlying conditions.
Pediatric Use
Widely used in pediatric populations. Dosing is weight-based and varies by indication. Safety and efficacy established for children 6 months and older for specific indications. Neonatal use is generally off-label and requires specific clinical justification.
Geriatric Use
No specific dosage adjustment is necessary based on age alone. However, elderly patients may be more susceptible to QT prolongation and should be monitored for this risk, especially if they have underlying cardiac conditions or are on concomitant QT-prolonging medications. Monitor renal and hepatic function.
Clinical Information
Clinical Pearls
- Azithromycin's long half-life allows for shorter treatment courses (e.g., 1-5 days) and once-daily dosing, which can improve patient adherence.
- It achieves high and sustained concentrations in tissues, often exceeding plasma concentrations, which contributes to its efficacy.
- Less prone to drug interactions via CYP450 inhibition compared to erythromycin or clarithromycin.
- Risk of C. difficile-associated diarrhea (CDAD) is a concern with all antibiotics, including azithromycin, and can occur even weeks after therapy.
- Taste masking is important for oral suspensions; ensure patients are aware of proper administration to minimize taste issues.
Alternative Therapies
- Other macrolides (e.g., clarithromycin, erythromycin)
- Penicillins (e.g., amoxicillin, amoxicillin/clavulanate)
- Cephalosporins (e.g., cefdinir, cefpodoxime)
- Tetracyclines (e.g., doxycycline, minocycline)
- Fluoroquinolones (e.g., levofloxacin, moxifloxacin) - generally reserved for specific indications due to broader spectrum and safety concerns.
