There are no adequate data from the use of Diclofenac sodium 4% Spray Gel (DicloFlex®) in pregnant and nursing women. Therefore the use is not recommended.
No evidence of a malformative effect was observed with diclofenac. However, additional epidemiological data is necessary to assess safety. During the last trimester of pregnancy, the use of prostaglandin synthetase inhibitors may result in:
Therefore, during the first six months of pregnancy, Diclofenac sodium 4% Spray Gel (DicloFlex®) should not be used unless clearly necessary and must not be applied to a large area of the skin (i.e. more than 600 square centimetres of the body surface). It must not be used for long-term treatment (> three weeks). Diclofenac sodium 4% Spray Gel (DicloFlex®) is contraindicated (see 4.3) during the last trimester of pregnancy.
Studies in animals have shown reproductive toxicity (see 5.3). The potential risk for humans is unknown.
It is not expected that any measurable amount of diclofenac will occur in breast milk following topical application. However, NSAIDs are excreted in human milk. Therefore Diclofenac sodium 4% Spray Gel (DicloFlex®) is not recommended for use in nursing mothers. An application to the breast area of nursing mothers is contraindicated.
