Lawsuits involving Depo-Provera (medroxyprogesterone acetate), an injectable contraceptive, allege that long-term use may be associated with an increased risk of certain brain tumors. These claims generally focus on risk communication—whether patients received adequate warnings and counseling about duration of use and potential long-term complications.
This page provides general educational information about the allegations, symptoms that should be evaluated by a clinician, and practical steps for patients who have concerns. It is not medical advice. Do not stop or change contraception without discussing options with a licensed healthcare provider.

What is Depo-Provera?
Depo-Provera is a prescription injectable form of progestin used to prevent pregnancy. It is administered on a schedule (commonly every three months). Some patients may also use it for other gynecologic reasons under a clinician’s direction. As with any medication, benefits and risks vary by individual health history, and risk discussions often include how long the medication is used.
What do the lawsuits allege?
The lawsuits generally allege that Depo-Provera use—particularly prolonged use—may be linked to a higher risk of certain brain tumors and that patients were not adequately warned. Claims often focus on:
- Whether labeling or risk communication adequately reflected potential long-term risks
- Whether patients were counseled appropriately about duration of use
- Whether safer alternatives should have been discussed for long-term contraception needs
An allegation does not automatically mean every user is at high risk, and individual risk varies. A healthcare provider is best positioned to help interpret symptoms, risk factors, and whether any evaluation is warranted.
Brain tumors: general context
“Brain tumor” is a broad term. Tumors can be benign (non-cancerous) or malignant (cancerous), and symptoms depend on tumor type, size, and location. Many common symptoms can be caused by non-tumor conditions, but persistent or worsening neurological symptoms should be evaluated.
Symptoms that should be evaluated
If you have used Depo-Provera and develop new or worsening neurological symptoms, consider seeking medical evaluation. Symptoms that merit prompt attention may include:
- Persistent or worsening headaches, especially new patterns or headaches that wake you from sleep
- Vision changes (blurred vision, double vision, loss of peripheral vision)
- New seizures or episodes of loss of awareness
- Weakness, numbness, tingling, or coordination problems
- Balance issues, dizziness, or difficulty walking
- Speech difficulty, confusion, memory changes, or personality changes
- Nausea/vomiting that is unexplained or persistent
If you experience sudden severe symptoms (seizure, sudden weakness, severe confusion, sudden vision loss), seek emergency care immediately.
What to discuss with your clinician
If you are concerned about potential risk, a focused conversation with your clinician can help. Consider discussing:
- Your duration of Depo-Provera use (approximate start/end dates, number of injections)
- Any neurological symptoms (what, when started, how often, severity, whether worsening)
- Relevant medical history (migraine, seizure history, clotting disorders, prior tumors, hormonal conditions)
- Whether imaging or referral is appropriate based on your symptoms and risk profile
- Contraception alternatives and a safe transition plan if you want to switch methods
If you are currently using Depo-Provera and want to stop, ask about timing and backup contraception to avoid unintended pregnancy.
Practical steps if you are concerned
These steps can help you prepare for a medical visit:
- Create a timeline: Write down injection dates (or approximate months/years of use).
- Track symptoms: Keep notes on headaches, vision changes, dizziness, or other symptoms.
- Gather records: Bring prior imaging, ER notes, or neurology visit summaries if available.
- List medications: Include all hormones, supplements, and migraine/neurology meds.
- Write questions: Ask what evaluation makes sense given your symptoms.
Frequently asked questions
Should I stop Depo-Provera immediately?
Do not stop or change prescription contraception without medical guidance. If you want to switch, discuss a safe transition plan with your clinician.
Do headaches mean I have a tumor?
No. Headaches are common and have many causes. However, new or worsening headaches—especially with other neurological symptoms—should be evaluated by a clinician.
What tests are used to evaluate tumor concerns?
Depending on symptoms and history, clinicians may recommend imaging such as MRI or CT and other testing as appropriate. Your provider will determine what is needed.
