Health Canada has issued new restrictions concerning the use of Terazol (terconazole). To read the full Health Canada Advisory, visit Health Canada's web site at

Condition does not improve: Check with your doctor if your condition does not improve after treatment. Failure to improve may also mean that the infection may not be fungal, or that another infection may have developed.

Condoms and diaphragms: Some of the ingredients in the ovule formulation may interact with certain natural rubber products, such as those used in condoms or vaginal contraceptive diaphragms. The use of the ovules with these is not recommended. The cream may be considered for use under these conditions.

Sensitivities: If sensitivity, vaginal irritation, fever, chills, or flu-like symptoms occur during use of terconazole, stop using the medication and call your doctor.

Pregnancy: This medication should not be used during the first trimester of pregnancy unless the benefits outweigh the risks. Pregnant women should exercise caution in using the vaginal applicator. If you become pregnant while taking this medication, contact your doctor.

Breast-feeding: It is not known if terconazole passes into breast milk. If you are a breast-feeding mother and are using this medication, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.

Children: The safety and effectiveness of this medication have not been established for children.

What other drugs could interact with this medication?

There may be an interaction between terconazole and any of the following:

If you are using any of these medications, speak with your doctor or pharmacist. Depending on your specific circumstances, your doctor may want you to:

  • stop using one of the medications,
  • change one of the medications to another,
  • change how you are using one or both of the medications, or

An interaction between two medications does not always mean that you must stop taking one of them. In many cases, interactions are intended or are managed by close monitoring. Speak to your doctor about how any drug interactions are being managed or should be managed.
