Azithromycin is a macrolide antibiotic used for a range of bacterial infections. This page explains key uses, dosing basics, safety, and how to order responsibly.

The treatment concentrates well in tissues and cells. It has a long half-life, which supports short courses and once-daily dosing for many labeled conditions. This medicine does not treat viral illnesses like colds or flu.

Who It’s For

This antibiotic is indicated for adults and eligible children for labeled bacterial infections such as community-acquired pneumonia, acute bacterial sinusitis, and certain skin and soft tissue infections. It also treats uncomplicated urethritis or cervicitis caused by susceptible organisms. For respiratory care topics, see Bacterial Respiratory Infection.

It may be used for acute otitis media in pediatrics when appropriate; review ear symptoms and diagnosis under Ear Infection. Selected sexually transmitted pathogens are covered; learn more at Sexually Transmitted Infection. Some uncomplicated skin infections are eligible; see Skin Infection. A common short course is sometimes referred to as z pak 250.

Do not use if you have a known allergy to macrolides or ketolides. People with a history of cholestatic jaundice or hepatic dysfunction associated with prior macrolide use should avoid re-exposure unless a clinician determines the benefits outweigh risks.

Dosage and Usage

Standard schedules vary by infection and patient age. Many adult respiratory infections are treated with a loading dose on day one followed by once-daily doses for several days, following the official label. A single-dose regimen may be used for certain uncomplicated urogenital infections. Pediatric dosing is typically weight-based using the oral suspension.

The azithromycin 250 mg dose pack is a common presentation for multi-day courses. Swallow tablets whole with water. You can take this medicine with or without food; taking with food may reduce stomach upset. Avoid taking aluminum- or magnesium-containing antacids at the same time; separate them by several hours.

Follow the full prescribed course even if you start to feel better earlier. Stopping too soon may allow the infection to return or foster resistance. If unsure about your schedule, consult the product’s official labeling or your prescriber.

Strengths and Forms

Available forms typically include film-coated tablets, oral suspension, and an intravenous formulation for clinical use. Common tablet strengths include 250 mg and 500 mg. Oral suspension strengths may include 100 mg/5 mL and 200 mg/5 mL after reconstitution. Extended-release oral suspension may be available for specific indications.

Availability can vary by pharmacy, manufacturer, and time. Not all strengths or forms are stocked continuously. Pack sizes, including dose packs, may differ by region and product line.

Missed Dose and Timing

If you miss a dose, take it when you remember unless it is close to the next scheduled dose. If it is nearly time for the next dose, skip the missed one and resume your usual schedule. Do not double doses to make up for a missed dose. Consistent timing once daily can help maintain stable levels.

Storage and Travel Basics

Store tablets at room temperature in a dry place away from excess heat and moisture. Keep the bottle tightly closed and out of reach of children and pets. If using oral suspension, follow the label for shelf life after it is mixed; discard any unused portion when it expires.

For travel, keep this medicine in its original labeled container in your carry-on. Bring your prescription or a copy of the label for security checks. Avoid prolonged exposure to hot cars or freezing temperatures. When shipping or transporting, use temperature-controlled handling when required.

Benefits

This antibiotic offers once-daily dosing for many indications. Short courses can be convenient for eligible infections. Tissue penetration and intracellular activity can support effectiveness against certain pathogens when used as directed by a clinician.

Side Effects and Safety

• Stomach upset: nausea or abdominal pain
• Diarrhea or loose stools
• Vomiting
• Headache
• Changes in taste

Serious but uncommon reactions can include allergic reactions, severe skin reactions, liver problems, and heart rhythm changes such as QT prolongation. Stop the medicine and seek urgent care for symptoms like rash with blistering, yellowing of the skin or eyes, fainting, palpitations, sudden swelling, or trouble breathing. Severe, persistent diarrhea may signal Clostridioides difficile–associated diarrhea and needs evaluation.

People with existing heart rhythm issues, low potassium or magnesium, or those taking other QT-prolonging drugs should discuss risks with a clinician. Patients with myasthenia gravis may experience worsening symptoms. Liver disease or previous liver injury with macrolides warrants caution.

Drug Interactions and Cautions

Separate aluminum- and magnesium-based antacids from doses to avoid reduced absorption. Use caution with warfarin or other anticoagulants, as monitoring may be needed. QT-prolonging agents, such as certain antiarrhythmics, may increase rhythm risks. Digoxin and some statins may interact; clinicians may monitor and adjust therapy as needed.

Avoid ergot derivatives due to potential toxicity. Always provide your clinician and pharmacist with a full medication and supplement list. For gastrointestinal conditions potentially related to infection, see Bacterial Gastrointestinal Infection. For veterinary-specific considerations, formulations and dosing differ; see Azithromycin for Pets or browse category options under Pet Medications.

What to Expect Over Time

Symptoms may begin to improve during the course as bacteria are suppressed. Complete the full regimen, even if you feel better before the last dose. If symptoms persist, worsen, or recur after finishing, contact your prescriber. Adherence, hydration, and rest support recovery for many infections.

Compare With Alternatives

For some conditions, a clinician may consider alternatives from other antibiotic classes. Tetracyclines such as Doxycycline may be selected for community-acquired respiratory infections when appropriate. Beta-lactams like Cephalexin are commonly used for certain skin and soft tissue infections. Some patients may be switched from brand-labeled options such as zithromax 250 mg to a suitable generic.

Availability and Substitutions

Stock may vary by strength and form. If an item is unavailable, your prescriber may recommend a clinically appropriate alternative. Ask about azithromycin 250 mg generic when comparing equivalent options. Do not switch antibiotics without guidance from your clinician.

Patient Suitability and Cost-Saving Tips

This treatment may suit adults and eligible children with labeled infections who can take a macrolide safely. It may not be ideal for people with significant liver disease, known QT prolongation, or a macrolide allergy. Your prescriber will review your history and concurrent medicines.

To lower costs, consider multi-month prescriptions when clinically appropriate, and align refills with follow-up visits. Use one pharmacy to keep records consolidated. Set reminder alerts so you do not miss doses. When traveling, carry a copy of the prescription and keep medicines in original containers for security checks.
