What Is Amoxicillin Clavulanate 400mg/57mg /5mL?

Amoxicillin clavulanate, sold under the brand name Augmentin, is an oral antibiotic suspension. It combines amoxicillin, a penicillin-class antibiotic that kills susceptible bacteria, with clavulanate, which blocks bacterial enzymes that would otherwise inactivate amoxicillin. This combination allows it to treat certain infections that amoxicillin alone cannot. Because it is a prescription-only medication, amoxicillin clavulanate is not available over the counter in the United States.

Frequently Asked Questions

Is amoxicillin clavulanate over the counter?

No. Amoxicillin clavulanate is a prescription-only antibiotic in the United States and is not available over the counter. A licensed healthcare provider must evaluate your condition and issue a valid prescription before a pharmacy can dispense it.

How much does amoxicillin clavulanate cost?

The cost varies by strength, quantity, insurance coverage, and pharmacy. As a generic medication, amoxicillin clavulanate suspension is generally affordable, and discount programs may lower the price further. Contact our pharmacy team for current pricing for your prescription.

Where to buy amoxicillin clavulanate?

You can fill a valid prescription for amoxicillin clavulanate at any licensed U.S. pharmacy, including ours. After a licensed provider reviews and approves your prescription, we dispense and ship the medication directly to you.

Do I need a prescription for amoxicillin clavulanate?

Yes. Federal law requires a valid prescription from a licensed healthcare provider for amoxicillin clavulanate. This ensures the antibiotic is appropriate for your infection and helps prevent antibiotic resistance from unnecessary use.

How does ordering and shipping work?

Submit your prescription or have your provider send it to our pharmacy. A licensed pharmacist reviews the order, and once approved, your medication ships from our licensed U.S. pharmacy in discreet packaging. Note that reconstituted suspension has a limited shelf life and should be refrigerated.

What is the difference between amoxicillin and amoxicillin clavulanate?

Amoxicillin clavulanate contains amoxicillin plus clavulanate, which blocks bacterial enzymes that can inactivate amoxicillin. This makes it effective against some bacteria that resist amoxicillin alone. Your provider will choose the appropriate antibiotic based on your infection.

How should I give the suspension to my child?

Shake the bottle well before each dose and measure with the provided dosing device, not a household spoon. Give doses at the start of a meal to reduce stomach upset, and complete the full prescribed course even if your child feels better.
