This medicine inhibits bacterial protein synthesis by binding to the 50S ribosomal subunit. It may help in respiratory, skin, and certain genitourinary infections caused by susceptible organisms. The azithromycin 250 mg oral tablet is typically taken once daily. Effects can vary by pathogen and site of infection. Always follow the approved label and your prescriber’s instructions.

It is not active against viruses like the common cold or flu. Using antibiotics only when indicated helps reduce resistance.

Who It’s For

Approved indications include acute bacterial sinusitis, community-acquired pneumonia, pharyngitis and tonsillitis, uncomplicated skin infections, and urethritis or cervicitis due to susceptible organisms. It may be used for azithromycin 250 mg for strep throat when appropriate, such as in patients who cannot take first-line options. Selection depends on local resistance patterns and clinical judgment.

People with a history of hypersensitivity to macrolides or ketolides should avoid this therapy. Use caution in those with known QT prolongation, arrhythmias, low potassium or magnesium, significant hepatic disease, or myasthenia gravis. For broader options, see our Bacterial Infections category.

Dosage and Usage

Typical regimens are infection-specific. Adult schedules often include an initial higher dose on day 1 followed by lower daily doses for a short course. In some cases, a single-dose regimen is used for certain sexually transmitted infections. Pediatric use is weight-based. The azithromycin 5 day dose pack 250 mg oral tablet is a commonly prescribed schedule; the exact total dose and duration depend on indication and labeling.

Take with a full glass of water. It can be taken with or without food; a light meal may help stomach upset. Avoid taking aluminum- or magnesium-containing antacids at the same time; separate by several hours. Do not crush or split tablets unless the label and your prescriber say it is acceptable.

Strengths and Forms

Multiple presentations exist; availability can vary by supplier and region.

• azithromycin 250 mg tablets USP
• 500 mg tablets
• Oral suspension (commonly 200 mg per 5 mL; other strengths exist)
• Extended-release oral suspension (single-use bottle; adult indications)

Not all strengths, pack sizes, or manufacturers are always in stock.

Missed Dose and Timing

If a scheduled tablet is missed, take it when remembered unless it is close to the next dose. If it is nearly time for the next dose, skip the missed dose and resume the regular schedule. Do not double up. For best results, complete the full prescribed course even if symptoms improve earlier.

Storage and Travel Basics

Store tablets at room temperature in a dry place, away from excess heat and moisture. Keep medicines in the original container with the label intact and out of reach of children and pets. When traveling, pack your medicine in carry-on baggage, bring a copy of the prescription, and keep doses on a consistent schedule across time zones. Dispose of expired or unused tablets according to local guidance.

Benefits

• Once-daily dosing for most indications
• Short-course therapy for many infections
• Oral formulation suits home treatment
• Option for patients who cannot take beta-lactam antibiotics
• Broad clinical experience across common infections

Side Effects and Safety

• Diarrhea or loose stools
• Nausea or vomiting
• Abdominal pain
• Headache
• Changes in taste

Serious risks are uncommon but can include allergic reactions, severe skin reactions, liver injury, irregular heart rhythm including QT prolongation, and Clostridioides difficile–associated diarrhea. Seek urgent care for symptoms such as swelling of the face or throat, severe rash, yellowing of the skin or eyes, chest pain, fainting, or persistent severe diarrhea. Report side effects to a healthcare professional.

Drug Interactions and Cautions

• Separate from aluminum- or magnesium-containing antacids by several hours
• Monitor with warfarin; interactions may increase anticoagulant effects
• Potential interaction with digoxin and certain immunosuppressants
• Use caution with other QT-prolonging medicines
• Tell a prescriber about liver disease, kidney issues, or myasthenia gravis

Some chronic therapies may interact or overlap in side effect profiles. For background on other common drug classes, see Common Diabetes Medications. Always review a full medication list, including over-the-counter products and supplements, with a healthcare professional.

What to Expect Over Time

Symptoms may change as the infection responds, but the pattern varies by condition and site. Continue the full course as prescribed. Skipping doses can reduce effectiveness and promote resistance. Use reminders if needed. If symptoms worsen or do not improve as expected, contact a clinician. Do not share antibiotics or save them for future illness. Follow-up testing or imaging may be advised for certain diagnoses.

Compare With Alternatives

Other antibiotics may be recommended based on the organism, site of infection, and local resistance patterns. Tetracyclines such as Doxycycline are often used for respiratory and skin infections when appropriate. First-generation cephalosporins like Cephalexin are options for certain skin and soft tissue infections. Selection should follow clinical guidelines and susceptibility data.

Availability and Substitutions

Equivalent generics may vary in manufacturer and packaging. We cannot guarantee substitutions without a matching prescription.

Patient Suitability and Cost-Saving Tips

This therapy may suit adults and children when a macrolide is indicated and tolerated. It may not suit patients with macrolide allergy, significant hepatic disease, or known risk factors for QT prolongation. Ask about multi-month quantities when appropriate, as larger fills can reduce per-tablet costs. Enable refill reminders so treatment courses are not interrupted. Keep medicines organized in a daily pillbox and bring a list of current medications to each appointment.
