Fifteen Years of Injections — Starting at Sixteen
Ashley was prescribed Depo-Provera at 16 to manage severe endometriosis pain. Her mother was relieved — four injections per year, no daily pill, no hormonal mood swings from the alternatives they'd tried. The gynecologist called it "one of the most reliable options." No one called it a risk.
By her late twenties, the headaches started. Persistent, pressure-like, nothing that ibuprofen could touch. Her GP attributed it to stress. Her optometrist noticed a subtle change in her peripheral vision. An MRI, ordered almost as an afterthought, revealed a meningioma — a slow-growing tumor at the base of her skull that required surgery.
She is 31 now, recovered from surgery, and part of a growing cohort of young women who researchers believe face disproportionate risk from Depo-Provera — precisely because they started young.
"Nobody told my mom or me that there was any connection between this shot and brain tumors. I was sixteen. They just said it would help my periods. I kept taking it for fifteen years because I had no reason not to. Now I feel like the decision was made for me — without all the information."

Why Younger First Use Means Higher Lifetime Risk
The biology here is straightforward, and the research is consistent: meningioma risk from Depo-Provera is tied to cumulative MPA exposure — the total dose of medroxyprogesterone acetate absorbed over time. A woman who starts at 16 and uses Depo-Provera for 12 years accumulates nearly three times the total hormonal exposure of a woman who starts at 30 and uses it for the same period relative to her reproductive timeline.
If continued to age 30: 14 years of exposure — approximately 56 injections, highest cumulative hormonal dose of any user cohort
If continued to age 30: 8 years of exposure — still significant, but 43% lower total dose than someone who started at 16
If continued to age 38: 8 years of exposure — same duration, but starting later means fewer total years of hormonal influence during formative adult brain development
The 2021 French epidemiological study that underpins much of the current litigation found that the meningioma risk was particularly concentrated in users with the highest cumulative progestin dose — a category that disproportionately includes women who began in their teens.
Why So Many Teenage Girls Were Prescribed Depo-Provera
Depo-Provera was not prescribed to teenage girls despite its convenience — it was prescribed because of it. Four injections per year, administered by a physician, with no daily compliance requirement, made it an attractive recommendation for young patients. The uses were wide-ranging:
The most common reason. Marketed as over 99% effective with no daily pill to forget. Widely prescribed to sexually active teenagers as a "set it and forget it" contraceptive option.
Girls diagnosed with endometriosis as young as 14 were routinely prescribed Depo-Provera to suppress menstruation and reduce pelvic pain — often continuing for many years.
Polycystic ovary syndrome often presents in adolescence. Depo-Provera was frequently used off-label to regulate hormonal symptoms, suppress ovulation, and reduce androgen levels.
Girls with menorrhagia (abnormally heavy periods) were prescribed Depo-Provera to suppress periods entirely — sometimes during middle and high school years, well before the full brain tumor risk was publicly disclosed.
The FDA did not require Pfizer to add a meningioma brain tumor warning to Depo-Provera's label until February 2024. The girls prescribed this medication in the 1990s, 2000s, and 2010s had no access to that warning — and neither did their parents or doctors.
Symptoms Young Women Should Watch For
Meningiomas often grow slowly and can be present for years before causing noticeable symptoms. Young women who used Depo-Provera for extended periods should be aware of the following warning signs — especially if symptoms are persistent or progressively worsening:
If you or your daughter used Depo-Provera for more than one year — especially starting in the teenage years — and are experiencing any of these symptoms, speak with your physician about an MRI evaluation. Early detection of meningioma is associated with significantly better outcomes.
Legal Options for Young Women Affected by Depo-Provera
If you or your daughter used Depo-Provera — particularly starting in your teenage years — and were diagnosed with a meningioma, here is what you should know about your legal options:
Product liability claims against Pfizer focus on the company's failure to adequately warn about the meningioma risk — not on what your individual doctor did or said. You do not need to prove your physician acted wrongly to pursue a claim against the manufacturer.
Plaintiffs who started Depo-Provera in their teens can demonstrate unusually high cumulative exposure — which directly corresponds to elevated meningioma risk. This can support both causation arguments and damages claims related to the length and severity of harm.
If you were under 18 when first prescribed Depo-Provera, additional legal considerations apply — including enhanced informed consent requirements for minors and, in some states, extended statutes of limitations that run from the age of majority rather than the date of injury.
