Augmentin is a penicillin antibiotic.

Augmentin contains a combination of amoxicillin and clavulanate potassium. Amoxicillin is an antibiotic in a group of drugs called penicillins. Clavulanate potassium is a form of clavulanic acid, which is similar to penicillin.  Together these two drugs are effective against a broad range of bacteria.

Do not use Augmentin if you are allergic to:

  • other penicillin antibiotic, such as amoxicillin (Amoxil, Augmentin, Dispermox, Moxatag)
  • ampicillin (Principen, Unasyn)
  •  dicloxacillin (Dycill, Dynapen)
  •  oxacillin (Bactocill)
  • penicillin (Bicillin L-A, PC Pen VK, Pfizerpen)

Supplied:  250, 500 or 875 mg tablets and 200 mg / 5 ml oral suspension

How we use it:  Typically, we use Augmentin to treat bacterial infections of the eyelids.


Adults: The usual adult dose is 1 Augmentin 500 mg tablet every 12 hours or 1 Augmentin 250 mg tablet every 8 hours.

Since both the Augmentin 250 mg and 500 mg tablets contain the same amount of clavulanic acid), 2 Augmentin 250 mg tablets are not equivalent to 1 Augmentin 500 mg tablet. Therefore, 2 Augmentin 250 mg tablets should not be substituted for 1 Augmentin 500 mg tablet.

Pediatric: Pediatric patients weighing 40 kg or more should be dosed according to the adult recommendations. Due to the different amoxicillin to clavulanic acid ratios in the Augmentin 250 mg tablet (250/ 125) versus the Augmentin 250 mg chewable tablet (250/ 62.5), the Augmentin 250 mg tablet should not be used until the pediatric patient weighs at least 40 kg or more.

Administration:   Augmentin may be taken without regard to meals; however, absorption of clavulanate potassium is enhanced when Augmentin is administered at the start of a meal. To minimize the potential for gastrointestinal intolerance, Augmentin should be taken at the start of a meal.

 Children: Augmentin should be used with extreme caution in CHILDREN who weigh less than 88 lbs (40 kg); safety and effectiveness in these children have not been confirmed.

Pregnancy:  Augmentin is not expected to be harmful to an unborn baby. (FDA pregnancy category B)

  • Amoxicillin and clavulanate potassium can pass into breast milk and may harm a nursing baby. Do not use Augmentin without telling your doctor if you are breast-feeding a baby.
  • Antibiotic medicines can cause diarrhea, which may be a sign of a new infection. If you have diarrhea that is watery or has blood in it, stop taking Augmentin and call your doctor.
  • Augmentin may cause dizziness. This effect may be worse if you take it with alcohol or certain medicines. Use Augmentin with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.
