Depo-Provera is typically prescribed to prevent pregnancy; however, it is also used to treat endometriosis and as a palliative treatment of certain cancers. Recent class actions have been launched in Canada on behalf of individuals who experienced serious side effects, including meningioma or bone mineral density loss. These legal actions seek to hold manufacturers accountable and pursue compensation for affected patients.
Depo Provera linked to meningioma
Use of Depo-Provera has been associated with an increased risk of diagnosis, growth, or recurrence of spinal or brain meningioma. Meningiomas are a type of tumour that grows within the tissues that line the central nervous system, also known as meninges.

FAQs
What is a class action?
A class action is a lawsuit that is brought by one or more person(s) on behalf of a larger group of people whose claims share common legal and/or factual issues. Class actions provide a cost-effective way for groups of people with common interests to pursue a legal claim.
What does “certification” mean?
Certification (or Authorization in Quebec) is the motion where the court determines whether the action can properly be pursued as a class action. The court will consider factors such as whether the claims of the class members raise common legal and/or factual issues and whether a class action is the preferable method of pursuing the claims (as opposed to other methods, such as individual actions).
