Zithromax 250 mg 500 mg Oral Suspension 200 mg per 5 mL

What is Zithromax?

Zithromax is the brand name for azithromycin, a macrolide antibiotic used to treat a wide variety of bacterial infections, including respiratory tract infections, ear infections, certain skin infections, and sexually transmitted infections like chlamydia. It is also used for some types of bacterial diarrhea and other gastrointestinal infections.

It is available in 250 mg and 500 mg tablets, as well as an oral suspension containing 200 mg per 5 mL for people who cannot swallow tablets or require precise dosing. Zithromax will not treat viral infections such as the common cold or flu. Using it unnecessarily increases the risk of antibiotic resistance. Generic azithromycin is widely available, and some patients buy refills online from licensed U.S. pharmacies to save money. Always ensure the product is legitimate, with clear labeling, the correct strength, and a valid expiration date.

How It Works

Azithromycin works by inhibiting bacterial protein synthesis. It binds to the 50S ribosomal subunit in bacteria, preventing them from producing proteins they need to grow and multiply. This action stops the spread of infection and allows the immune system to eliminate the bacteria.

Azithromycin is known for its long half life, which allows for once daily dosing and shorter treatment courses compared to many other antibiotics.

What you may notice

Symptoms such as fever, sore throat, or cough may improve within a few days, but you should continue taking the full course as prescribed to fully clear the infection.

Dosage Information

Dosing varies based on the type of infection, patient age, and kidney or liver function. Always follow your prescription exactly.

• Most infections in adults: 500 mg on day 1, then 250 mg once daily on days 2 through 5.
• Sexually transmitted infections: Single 1 gram dose by mouth.
• Children: Dosing is based on weight, typically 10 mg per kilogram on day 1, then 5 mg per kilogram once daily for days 2 through 5.

How to take it

Take with or without food. Swallow tablets whole with water. Shake oral suspension well before measuring each dose. If you miss a dose, take it when remembered unless it is near your next scheduled dose—then skip it. Do not double up.

Cost and access tips

Generic azithromycin is inexpensive and widely available. Buying from licensed online pharmacies can save money. Cheap pricing is fine when labeling and expiration dates are clear, and a pharmacist is available for questions.

Side Effects

Common side effects include nausea, diarrhea, abdominal pain, and headache. These are generally mild and resolve after treatment ends.

Less common but important

• Allergic reactions: Rash, swelling, or trouble breathing require immediate medical attention.
• Liver changes: Rare cases of hepatitis or liver failure have been reported.
• Heart rhythm changes: Azithromycin can cause QT prolongation in some people, increasing the risk of irregular heartbeat.

Warnings & Interactions

Zithromax should be used with caution in people with liver disease, kidney disease, or certain heart conditions. It may cause QT prolongation, especially in those taking other drugs with the same effect.

Drug interactions

• Antacids with aluminum or magnesium: Can reduce absorption; take Zithromax at least 2 hours before or after these products.
• Other QT prolonging medicines: May increase risk of dangerous heart rhythms.
• Warfarin: Can increase bleeding risk; monitoring is recommended.

Practical safety tips

Complete the full course even if you feel better. Avoid unnecessary antibiotic use to prevent resistance. If buying Zithromax online, choose licensed U.S. pharmacies, verify labeling and expiration dates, and ensure the product is authentic. Cheap pricing is acceptable when those checks are met.
