Augmentin Oral

Generic Name: AMOXICILLIN/CLAVULANIC ACID CHEWABLE TABLET - ORAL
Pronounced: (a-MOX-i-SIL-in/KLAV-you-lan-ik)

Augmentin Oral Side Effects

Diarrhea, nausea, or vomiting may occur during the first few days as your body adjusts to the medication. Take with food to minimize stomach upset. If any of these effects persist or worsen, contact the doctor or pharmacist promptly.

This medicine may cause temporary staining of the teeth. Proper brushing will usually remove any staining and may prevent it from occurring.

Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Tell the doctor immediately if any of these highly unlikely but very serious side effects occur:

  • easy bruising or bleeding
  • persistent sore throat or fever
  • dark urine
  • persistent nausea or vomiting
  • severe stomach/abdominal pain
  • yellowing eyes or skin


This medication may rarely cause a severe intestinal condition (pseudomembranous colitis) due to a type of resistant bacteria. This condition may occur during treatment or weeks to months after treatment has stopped. Do not use anti-diarrhea products or narcotic pain medications if you have any of the following symptoms because these products may make them worse. Tell the doctor immediately if you develop: persistent diarrhea, abdominal or stomach pain/cramping, or blood/mucus in your stool.

Use of this medication for prolonged or repeated periods may result in oral thrush or a new vaginal yeast infection (oral or vaginal fungal infection). Contact the doctor if you notice white patches in your mouth, a change in vaginal discharge or other new symptoms.

A very serious allergic reaction to this drug is unlikely, but seek immediate medical attention if it occurs. Symptoms of a serious allergic reaction may include:

  • rash
  • itching/swelling (especially of the face/tongue/throat)
  • severe dizziness
  • trouble breathing


The amoxicillin in this combination medication can commonly cause a mild rash that is usually not serious. However, you may not be able to tell it apart from a rare rash that could be a sign of a severe allergic reaction. Therefore, seek immediate medical attention if you develop any rash.

This is not a complete list of possible side effects. If you notice other effects not listed above, contact the doctor or pharmacist.

Call your doctor for medical advice about side effects. In the US, you may report side effects to the Food and Drug Administration (FDA) at 1-800-FDA-1088.

In Canada, you may report side effects to Health Canada at 1-866-234-2345.
