Health Canada Endorsed Important Safety Information on TERAZOL 7 (terconazole) Vaginal Cream and TERAZOL 3 Dual-Pak (terconazole) Vaginal Cream/Vaginal Ovules

June 9, 2014

Dear Healthcare Professional:

Subject: New safety information regarding the risk of anaphylaxis and Toxic Epidermal Necrolysis (TEN) associated with TERAZOL® 7 Vaginal Cream 0.4% (terconazole); TERAZOL® 3 Dual-Pak®- Vaginal Cream 0.8%/Vaginal Ovules 80 mg (terconazole)

Janssen Inc., in consultation with Health Canada, would like to provide you with important new safety information regarding the risk of anaphylaxis and Toxic Epidermal Necrolysis associated with the use of TERAZOL®. A Public Communication (PC) to inform patients of this new safety information has also been posted on Janssen Inc. and Health Canada websites.

TERAZOL® 7 Vaginal Cream and TERAZOL® 3 Dual-Pak® Vaginal Cream/Vaginal Ovules are authorized for the local treatment of vulvovaginal candidiasis (moniliasis). The diagnosis of monilial infection should be confirmed by microscopic examination of a KOH smear and/or by culture.

  • Very rare cases of serious or even life-threatening adverse reactions of anaphylaxis or Toxic Epidermal Necrolysis (TEN) have been reported during treatment with TERAZOL®.
  • The Canadian Product Monograph for TERAZOL® has been updated to include this new safety information.
  • Patients should be counseled about the risks of anaphylaxis and TEN with TERAZOL® and instructed to discontinue use of the product if signs or symptoms of serious allergic reactions occur.

The WARNING section of the Product Monograph for TERAZOL® has been updated to include this new safety information. The text of the WARNING reads as follows:


Anaphylaxis and Toxic Epidermal Necrolysis have been reported during terconazole therapy. TERAZOL® therapy should be discontinued if anaphylaxis or Toxic Epidermal Necrolysis develops (see ADVERSE REACTIONS).

In addition, the Post-Market Adverse Drug Reactions and the Consumer Information Sections of the Product Monograph have been modified to include anaphylaxis and TEN.

Please refer to the TERAZOL® Product Monograph for full prescribing information.

The current TERAZOL® Product Monograph can be found at the Janssen Canada Web site and Health Canada’s Web page.

Managing marketed health product-related adverse reactions depends on health care professionals and consumers reporting them. Reporting rates determined on the basis of spontaneously reported post-marketing adverse reactions are generally presumed to underestimate the risks associated with health product treatments. Any case of anaphylaxis, TEN, or other serious or unexpected adverse reactions in patients receiving TERAZOL® 7 or TERAZOL® 3 Dual-Pak® should be reported to Janssen Inc. or Health Canada.
