What Is Augmentin (Amoxicillin/Clavulanate)?
Augmentin, a combination of amoxicillin and clavulanate, is a prescription broad-spectrum antibiotic used to treat a wide range of bacterial infections. It combines a penicillin-class antibiotic (amoxicillin) with clavulanate, a beta-lactamase inhibitor that extends the drug’s effectiveness against bacteria that develop resistance. Because of this enhanced action, Augmentin is often chosen when a standard amoxicillin clavulanate antibiotic is needed to treat more persistent or complex infections.
In the United States, Augmentin is FDA-approved and available only with a prescription. It comes in various formulations, including tablets, chewables, and oral suspension. Many patients look for ways to buy Augmentin online or seek information about proper clinical use, particularly when treating common infections such as sinusitis or respiratory conditions. As with all antibiotics, Augmentin should be taken exactly as directed to ensure safe and effective treatment.
What Is Augmentin Used For?
Augmentin is prescribed for a variety of bacterial infections in both adults and children. Its expanded coverage makes it especially useful when clinicians suspect bacteria that produce beta-lactamase enzymes or when first-line antibiotics are not sufficient.
Common clinical uses include:
- Sinus infections (sinusitis) – one of the most frequent reasons patients receive Augmentin for sinus infection
- Ear infections (otitis media)
- Lower respiratory infections, including pneumonia and acute bronchitis
- Skin and soft tissue infections, such as cellulitis and wound infections
- Bite wound infections, including dog and human bites
- Urinary tract infections (UTIs) in select cases
Augmentin is also used in several guideline-supported off-label situations where broader coverage is needed. Because bacterial resistance patterns vary, only a qualified healthcare provider can determine whether Augmentin is the appropriate antibiotic for a specific condition.

Buy Augmentin Without a Prescription – Is It Legal in the USA?
Augmentin is a prescription-only antibiotic in the United States, meaning it cannot be legally obtained without a valid prescription. Any website offering Augmentin without prescription poses significant safety risks, as these sources often bypass FDA regulations and may sell counterfeit or improperly stored medication.
Because Augmentin contains two active ingredients amoxicillin and clavulanate its use requires medical evaluation to ensure the infection is appropriate for this combination therapy. Incorrect use can lead to treatment failure or contribute to antibiotic resistance. Patients who need Augmentin but cannot visit a doctor in person can legally obtain a prescription through licensed U.S. telehealth services, where a clinician reviews symptoms and determines whether the medication is suitable.
Can I Buy Augmentin Over the Counter?
Augmentin is not available over the counter (OTC) in the United States. There is no OTC version of amoxicillin/clavulanate, because this combination antibiotic requires medical oversight to ensure safe and effective treatment. Some symptoms associated with bacterial infections can be temporarily managed with OTC pain relievers or fever reducers, but these products do not treat the infection itself.
A healthcare provider must confirm whether Augmentin is appropriate, especially for conditions such as sinusitis, ear infections, pneumonia, or bite wounds. Because clavulanate increases the medication’s potency, misuse without prescription can result in stomach upset, allergic reactions, or complications. For these reasons, Augmentin OTC options do not exist in the U.S.
Augmentin Price in the USA
The price of Augmentin varies depending on the dosage strength, formulation, pharmacy, and whether the patient is purchasing the brand-name version or a generic equivalent such as amoxicillin clavulanate 875 mg or 500 mg tablets. Many patients compare prices online to find the best deals, especially when purchasing through verified U.S. pharmacies. Generic versions are significantly more affordable and offer the same therapeutic effect as the brand-name drug.

Augmentin Dosage Guide
Augmentin dosing depends on the infection type, patient age, weight, and severity. Because misuse of antibiotics can lead to resistance or side effects, amoxicillin/clavulanate should be taken only under the supervision of a healthcare provider. The provider will determine whether to use standard or high-dose formulations, such as 875/125 mg, based on clinical needs.
Typical Augmentin Dosage Examples
- Sinusitis: 875/125 mg every 12 hours for 5–10 days
- Skin and soft tissue infections: 500/125 mg every 12 hours or 250/125 mg every 8 hours
- Ear infections (otitis media): dosing varies by age and severity
- Pneumonia: 875/125 mg every 12 hours, depending on clinical judgement
- Bite wound infections: 875/125 mg every 12 hours for 7–14 days
Patients should take Augmentin with food to reduce stomach upset and ensure optimal absorption. If a dose is missed, it should be taken promptly unless the next scheduled dose is close. Completing the full treatment course is essential, even if symptoms improve early.
