Depo-Provera Contraceptive Jab Linked To Increased Meningioma Risk: Urgent Health Alert
The Widely-Used Contraceptive Injection, Depo-Provera, has come under scrutiny following the release of a study linking its long-term use to an elevated risk of developing meningioma, a type of brain tumor. The Findings have prompted concerns among women and calls for enhanced patient information and monitoring.
Alarming Link Between contraceptive Jab and Brain Tumors
A Recent Analysis Published in a prominent medical journal revealed that women who used Depo-Provera,also known as medroxyprogesterone acetate,for more than one year were five times more likely to develop meningioma compared to those who did not use the injection.The Study, conducted by the French National Agency for Medicines and Health Products Safety, examined data from over 18,000 women who underwent surgery for meningioma between 2009 and 2018.
The Results Indicated a significantly higher incidence of meningioma among women using the Depo-Provera jab. Depo-Provera is administered every three months and prevents pregnancy by stopping the release of eggs. In England alone, doctors issue approximately 10,000 prescriptions for it each month as it helps women avoid taking a daily pill.
Experts Weigh In On Meningioma Risk
Dr. Simon Newman, Chief Scientific Officer at The Brain Tumor Charity, illuminated the statistical impact of Depo-Provera on meningioma incidence. “Normally, out of every 1,000 women aged 30, you would expect to see four cases of meningioma by the time they reach 80,” Dr. Newman explained. “With Depo-Provera, that increases to 20 cases per 1,000 women – so even though its still small, the risk is greater.”
Following the Study’s Publication, the UK drug safety watchdog, the Medicines and Healthcare Products Regulatory agency (MHRA), urged pfizer, the jab’s manufacturer, to include a warning about this potential risk in patient information leaflets. Pfizer also contacted NHS doctors, advising them to promptly discontinue Depo-Provera use in women diagnosed with meningioma.
Understanding The Potential Mechanism
The Exact Mechanism through which Depo-Provera may trigger tumor growth remains unclear, but researchers suspect it involves synthetic forms of progesterone (progestogens).Approximately 70% of meningioma cells possess progesterone receptors, suggesting that synthetic hormones may bind to these receptors and stimulate tumor growth.
Additional Research by the French Team has also indicated an elevated risk with certain, but not all, oral contraceptives containing progestogens. As a notable example, women who used pills containing levonorgestrel (a type of progestogen) for five years or more faced a 50% higher risk of meningioma, even though the overall numbers affected remained small. This underscores the need for further investigation into hormonal contraceptives and their potential effects on brain tumor growth.
Real-Life Impact: Women Share Their Stories
While the precise number of UK women who have developed tumors after using Depo-Provera is unkown, numerous accounts have emerged. One law firm reported contact from at least 200 women in the UK over the past year, seeking information and potential legal recourse. Several women shared similar sentiments: they were not informed of the possible risks and only discovered the connection after developing severe headaches and being diagnosed with meningioma.
Chaya Hanoomanjee,Managing Director at London law firm Austen Hays,specializing in class actions,confirmed that her firm is investigating the grounds for a potential UK case against pfizer. “The Big Question is whether the manufacturer was aware of the risks before the study but failed to alert women,” Hanoomanjee stated.
Manufacturer’s Response
Pfizer UK Declined To comment on whether it had prior knowledge of the increased meningioma risk before the study was published.
The Role Of Hormones In Meningioma Growth
Dr. Newman emphasized that natural hormonal fluctuations, notably progesterone spikes during pregnancy, can also influence meningioma growth. “Pregnancy does appear to increase the rate of growth of meningioma cells,” he noted, “and that means women do seem to be twice as likely to get it as men.” This highlights the complex interplay between hormones and meningioma development.
| Hormonal Factor | impact on Meningioma Risk |
|---|---|
| Depo-Provera Use (Long-Term) | 5x Increased risk |
| Oral contraceptives (Levonorgestrel) | 50% Higher Risk (after 5+ years) |
| Pregnancy | Increased Rate of Growth |
Beyond the Headlines: Understanding meningioma
Meningiomas are tumors that arise from the meninges,the membranes surrounding the brain and spinal cord. While most meningiomas are benign (non-cancerous), they can cause significant health problems depending on their size and location.
Symptoms of meningioma can vary widely, but common signs include persistent headaches, vision changes, seizures, weakness in the arms or legs, and changes in personality or behavior. It’s crucial to consult a healthcare professional if you experience any of these symptoms, especially if you have a history of hormonal contraceptive use.

Factors Influencing Meningioma Risk
- Hormone Exposure: as highlighted by recent studies, prolonged exposure to synthetic progestogens can elevate the risk of meningioma.
- radiation Exposure: Previous radiation therapy to the head can increase the likelihood of developing meningioma later in life.
- Genetic Conditions: Certain genetic disorders, such as neurofibromatosis type 2, are associated with a higher risk of meningioma.
- Age and Gender: Meningiomas are more common in older adults and are more frequently diagnosed in women than in men.
Pro tip: If you have concerns about meningioma risk, discuss your medical history and any potential risk factors with your doctor.Regular check-ups and screenings can help detect tumors early, when treatment is often more effective.
Frequently Asked Questions
-
What is Depo-Provera and what is it used for?
Depo-Provera is an injectable contraceptive that contains medroxyprogesterone acetate, a synthetic form of progesterone. It is used to prevent pregnancy by preventing the release of eggs from the ovaries.
-
What are the potential risks associated with Depo-Provera?
Recent studies suggest that using Depo-Provera for more than a year may increase the risk of developing a meningioma, a type of brain tumor. This risk is still considered small but is significantly greater compared to women who do not use the jab.
-
How significant is the increased risk of meningioma with Depo-Provera usage?
According to research, the risk increases from approximately four cases of meningioma per 1,000 women by age 80 to about 20 cases per 1,000 women who use Depo-Provera.
-
What have regulatory agencies and manufacturers done in response to these findings?
The Medicines And Healthcare Products Regulatory Agency (MHRA) has called on Pfizer, the manufacturer of Depo-Provera, to include a warning about the meningioma risk in patient information leaflets. Additionally, Pfizer has advised NHS doctors to stop prescribing Depo-Provera to women diagnosed with a meningioma.
-
Are there any legal actions related to Depo-Provera and meningioma?
Yes, there is a class action lawsuit in the United States against Pfizer on behalf of women who believe the Depo-Provera injection caused their meningioma tumors. Law firms in the UK are also investigating potential cases against Pfizer.
-
What should I do if I am currently using Depo-Provera?
If you are using Depo-Provera and are concerned about the risk of meningioma, consult with your healthcare provider.Discuss alternative contraceptive options and monitor for any unusual symptoms.
