5 Warnings and Precautions

5.3 Drug-Induced Enterocolitis Syndrome (DIES)

Newly added subsection:

Drug-induced enterocolitis syndrome (DIES) has been reported with use of amoxicillin, a component of AUGMENTIN [see Adverse Reactions (6.2)], with most cases occurring in pediatric patients less than or equal to 18 years of age. DIES is a non-IgE mediated hypersensitivity reaction characterized by protracted vomiting occurring 1 to 4 hours after drug ingestion in the absence of skin or respiratory symptoms. DIES may be associated with pallor, lethargy, hypotension, shock, diarrhea within 24 hours of ingesting amoxicillin, and leukocytosis with neutrophilia. If DIES occurs, discontinue AUGMENTIN and institute appropriate therapy.

6 Adverse Reactions

Additions and revisions underlined:

The following are discussed in more detail in other sections of the labeling:

  • Anaphylactic reactions [see Warnings and Precautions (5.1)]

  • Severe Cutaneous Adverse Reactions [see Warnings and Precautions (5.2)]

  • Drug-Induced Enterocolitis Syndrome (DIES) [see Warnings and Precautions (5.3)]

  • Hepatic Dysfunction [see Warnings and Precautions (5.4)]

  • Clostridioides difficile Associated Diarrhea (CDAD) [see Warnings and Precautions (5.5)]

6.2 Postmarketing Experience

Additions and revisions underlined:

. . .

Gastrointestinal: Drug-induced enterocolitis syndrome (DIES), indigestion, gastritis, stomatitis, glossitis, black “hairy” tongue, mucocutaneous candidiasis, enterocolitis, and hemorrhagic/pseudomembranous colitis. Onset of pseudomembranous colitis symptoms may occur during or after antibacterial treatment [see Warnings and Precautions (5.5)].

. . .

Skin and Appendages: Rashes, pruritus, urticaria, erythema multiforme, SJS, TEN, DRESS, AGEP, exfoliative dermatitis, and linear IgA bullous dermatosis.

5 Warnings and Precautions

5.2 Severe Cutaneous Adverse Reactions

 

New subsection added

AUGMENTIN may cause severe cutaneous adverse reactions (SCAR), such as Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), drug reaction with eosinophilia and systemic symptoms (DRESS), and acute generalized exanthematous pustulosis (AGEP). If patients develop a skin rash, they should be monitored closely, and AUGMENTIN discontinued if lesions progress.

5.8 Development of Drug-Resistant Bacteria

Additions and/or revisions underlined

Prescribing AUGMENTIN in the absence of a proven or strongly suspected bacterial infection or a prophylactic indication is unlikely to provide benefit to the patient and increases the risk of the development of drug?resistant bacteria.

6 Adverse Reactions

Addition of the following to the bulleted line listing:

  • Severe Cutaneous Adverse Reactions [see Warnings and Precautions (5.2)]

    6.2 Postmarketing Experience

    Additions and/or revisions underlined

    Immune: Hypersensitivity reactions, anaphylactic/anaphylactoid reactions (including shock), angioedema, serum sickness-like reactions (urticaria or skin rash accompanied by arthritis, arthralgia, myalgia, and frequently fever), hypersensitivity vasculitis [see Warnings and Precautions (5.1)].

    Skin and Appendages: Rashes, pruritus, urticaria, erythema multiforme, SJS, TEN, DRESS, AGEP, exfoliative dermatitis [see Warnings and Precautions (5.2)].

17 PCI/PI/MG (Patient Counseling Information/Patient Information/Medication Guide)

PATIENT COUNSELING INFORMATION

Additions and/or revisions underlined

Severe Cutaneous Adverse Reactions (SCAR)

Advise patients about the signs and symptoms of serious skin manifestations. Instruct patients to stop taking AUGMENTIN immediately and promptly report the first signs or symptoms of skin rash, mucosal lesions, or any other sign of hypersensitivity [see Warnings and Precautions (5.2)].

Diarrhea

Counsel patients that diarrhea is a common problem caused by antibacterials, and it usually ends when the antibacterial is discontinued. Sometimes after starting treatment with antibacterials, patients can develop watery and bloody stools (with or without stomach cramps and fever) even as late as 2 or more months after having taken their last dose of the antibacterial. If diarrhea is severe or lasts more than 2 or 3 days, patients should contact their physician as soon as possible.

Storage Instructions

Advise patients to keep suspension refrigerated. Shake well before using. When dosing a child with the suspension (liquid) of AUGMENTIN, use a calibrated oral syringe. Be sure to rinse the calibrated oral syringe after each use. Bottles of suspension of AUGMENTIN may contain more liquid than required. Follow your doctor’s instructions about the amount to use and the days of treatment your child requires. Discard any unused medicine.
