Augmentin 375 mg is one of the most widely prescribed antibiotics worldwide. It combines amoxicillin and clavulanic acid, making it highly effective against bacterial infections that may not respond to standard antibiotics. In this complete guide, we’ll cover uses, dosage, side effects, precautions, interactions, and tips to use Augmentin safely.
Whether you’re a patient prescribed this antibiotic or someone researching it, this guide provides everything you need to know.
What is Augmentin 375 mg?
Augmentin 375 mg is a prescription-only antibiotic that contains two active ingredients:
- Amoxicillin (250 mg): A penicillin-type antibiotic that kills bacteria by interfering with their cell walls. Learn more at Mayo Clinic
- Clavulanic acid (125 mg): A beta-lactamase inhibitor that prevents bacteria from breaking down amoxicillin, increasing its effectiveness.
This combination makes Augmentin effective against bacteria that are resistant to amoxicillin alone, allowing doctors to treat a wide range of infections.
Uses of Augmentin 375 mg
Augmentin 375 mg is prescribed for multiple bacterial infections:
1. Respiratory Tract Infections
- Sinusitis – inflammation of the sinuses caused by bacterial infection.
- Bronchitis – infection of the bronchial tubes leading to cough and mucus production.
- Pneumonia – serious lung infection caused by bacteria.
2. Ear, Nose, and Throat Infections
- Otitis media – middle ear infection, common in children.
- Tonsillitis – bacterial infection of the tonsils.
- Pharyngitis – bacterial throat infections causing pain and swelling.
3. Skin and Soft Tissue Infections
- Cellulitis – bacterial infection of the skin and tissues.

5. Dental Infections
Systemic antibiotics like Augmentin can prevent the spread of severe dental infections.
Important: Augmentin does not treat viral infections like the cold or flu. Misuse can lead to antibiotic resistance.
How Augmentin Works
The antibiotic works through a two-step mechanism:
- Amoxicillin targets bacterial cell walls, causing the bacteria to die.
- Clavulanic acid protects amoxicillin from beta-lactamase enzymes that some bacteria produce to resist treatment.
This combination makes Augmentin 375 mg a broad-spectrum antibiotic that can treat resistant infections.

The correct dosage depends on age, weight, and infection severity:
Adults
