Precautions and Warnings
This product can cause damage to latex condoms and diaphragms.
Patients using spermicidal contraceptives should consult their clinician as vaginal treatment may inactivate the spermicidal contraceptive.
Econazole pessaries should be discontinued if hypersensitivity reactions occur.
Pregnancy (see Pregnancy ).
Male sexual partners should also be treated with econazole cream to prevent re-infection with Candida.
One course of therapy is usually sufficient to treat the infection, however a second course may be necessary.
Pregnancy and Lactation
Econazole pessaries should only be used during pregnancy if a physician considers it necessary.
As with other agents, the pessaries should not be used in the first trimester of pregnancy unless the physician deems it essential for the welfare of the patients (Briggs, 2011).
It is not know whether econazole nitrate crosses the placenta although the molecular weight (about 445) is low enough for this to be expected. In animal studies, econazole has shown no teratogenic effects but is foetotoxic at high doses. It is not known how significant this is in relation to humans and there is no evidence of increased risk when administered during human pregnancy.
During pregnancy, extra care should be taken in using a vaginal applicator to prevent the possibility of mechanical trauma.
The use of all medication in pregnancy should be avoided whenever possible; particularly in the first trimester. Non-drug treatments should also be considered. When essential, a medication with the best safety record over time should be chosen, employing the lowest effective dose for the shortest possible time. Polypharmacy should be avoided. Teratogens taken in the pre-embryonic period, often quoted as lasting until 14-17 days post-conception, are believed to have an all-or-nothing effect. Where drugs have a short half-life, and when the date of conception is certain, this may allow women to be reassured where drug exposure has occurred within this time frame.

No specific information on the effects of vaginal econazole on lactation are available. However low systemic bioavailability after topical use suggests that the quantities of econazole excreted in breast milk would be low. The risk of exposure to nursing infants is therefore considered to be low.
Neonates, infants born prematurely, those with low birth weight, those with an unstable gastrointestinal function or who have serious illnesses may require special consideration. For any infant, if a drug is prescribed to the nursing mother, it should be at the lowest practical dose and for the shortest time. When drug administration is unavoidable and breastfeeding is to continue, minimisation of exposure of the infant to the drug may sometimes be achieved by timing the maternal doses to just after a feeding episode. Infants exposed to drugs via breast milk should be monitored for unusual signs or symptoms. Interactions between the drug received by the infant from the mother's milk and medication prescribed for the infant should also be considered, for example, when the drug given to the infant may prevent metabolism of the drug received via breast milk.

Advise patients that the preparation damages latex condoms and diaphragms.
Advise patients that using econazole cream to treat sexual partners at the same time lessens the risk of re-infection.
Advise patients not to use spermicidal contraceptives unless under the guidance of a clinician as they may be inactivated by this preparation.
