Non-steroidal anti-inflammatory drugs beyond 20 weeks of pregnancy, risk of kidney damage to unborn babies
This can lead to low levels of amniotic fluid and possible complications, such as impaired lung maturation and loss of joint movement (limb contractures) in the newborn baby.
As a result of its findings, Health Canada is advising that pregnant women not use NSAIDs from approximately 20 to 28 weeks of pregnancy, unless advised to do so by their healthcare professional. Prescription and non-prescription NSAID product labels will be updated with this new information.
If a healthcare professional decides that the use of NSAIDs between 20 and 28 weeks of pregnancy is necessary, Health Canada recommends that they use the lowest effective dose for the shortest duration possible, and that they consider monitoring amniotic fluid levels via ultrasound if treatment extends beyond 48 hours. These recommendations do not apply to the use of low-dose (81 mg) aspirin, pediatric-only formulations (i.e., those only indicated for children less than 12 years of age) or NSAIDs administered directly to the eye.
Health Canada continues to monitor the situation closely and will take further action to help protect the health and safety of Canadians, if necessary. This includes continuing to work with Canadian manufacturers of NSAID products to take appropriate action in Canada in light of this new evidence. ■
