Platelet-rich plasma, or PRP, has gained popularity among athletes and individuals seeking non-surgical treatments for various conditions such as hair loss, joint pain, and skin rejuvenation. However, despite its popularity, PRP is not yet approved by the Food and Drug Administration (FDA), leaving many people to wonder why.
PRP is a treatment that involves extracting a patient’s blood, spinning it in a centrifuge to separate the platelets and plasma from other blood components, and then injecting the concentrated platelets back into the patient’s body at the site of injury or other areas of concern. While PRP has shown promising results in many cases, the lack of FDA approval has raised questions about its safety and effectiveness.
For years, the FDA has been evaluating PRP to determine whether it should be approved for widespread use. Despite this ongoing evaluation process, PRP has not yet been granted official approval by the FDA. This has led some healthcare professionals to caution against the use of PRP, citing concerns about the lack of regulation, standardization, and potentially harmful side effects. However, despite these concerns, many patients continue to seek out PRP treatments, hoping for a non-surgical solution to their medical or cosmetic needs.
FDA Approval Process Overview
The FDA (Food and Drug Administration) is responsible for regulating the safety and effectiveness of medical treatments and devices in the United States. In order for a treatment or device to receive FDA approval, it must go through a rigorous testing process that can take several years.
- Preclinical Testing: Before human testing can begin, a treatment or device must be tested extensively in a laboratory setting. This includes testing on animals to determine safety and preliminary effectiveness.
- Phase 1 Clinical Trials: If preclinical testing shows promise, the treatment or device moves on to phase 1 clinical trials, which involve a small group of healthy volunteers. The goal of this phase is to determine the treatment’s safety and dosage range.
- Phase 2 Clinical Trials: In this phase, the treatment is tested on a larger group of patients to determine its effectiveness and possible side effects.
- Phase 3 Clinical Trials: This is the final phase of testing before submitting an application to the FDA. The treatment is tested on a larger group of patients to confirm its effectiveness and monitor any potential side effects over a longer period of time.
- New Drug Application (NDA): After successfully completing all three phases of clinical trials, the drug manufacturer submits an NDA to the FDA. The application includes all relevant test results, along with proposed labeling and information about production methods and other details.
- Review: The FDA reviews the NDA and makes a decision about whether or not to approve the treatment. This process can take several months.
- Post-Marketing Surveillance: Once a drug is approved and marketed, the FDA continues to monitor its safety and effectiveness through post-marketing surveillance and reporting mechanisms.
Why is PRP not FDA Approved?
While PRP (platelet-rich plasma) therapy has been gaining popularity in recent years for its potential to treat a variety of conditions, it has not yet received FDA approval. This means that PRP treatments are considered experimental and insurance may not cover them.
The reason for this lack of FDA approval is that PRP therapy is considered a medical procedure, not a drug. As such, it falls into a regulatory gray area that makes it difficult for the FDA to establish clear guidelines for safety and effectiveness. Additionally, the variability of PRP preparations and the lack of standardization in treatment protocols make it difficult to establish consistent results and provide clear data for regulatory approval.
However, many clinics and medical professionals still offer PRP therapy as an option for patients, citing anecdotal evidence of its effectiveness and safety. It is important for patients to carefully consider the risks and benefits of any medical treatment, and to explore all available options before making a decision.
PRP Mechanism of Action
Platelet-rich plasma therapy works on the principle of regeneration and healing. It is based on the ability of platelets, which are tiny blood cells, to stimulate tissue repair and regeneration.
- Platelets are rich in growth factors and cytokines that help in healing injuries, and promoting tissue repair and regeneration.
- During PRP therapy, blood is drawn from the patient and processed to concentrate the platelets and growth factors.
- The concentrated platelets are then injected back into the patient’s body at the site of injury or tissue damage.
This concentration of platelets and growth factors is much higher than what is present in the patient’s blood. By injecting this concentrated mixture directly into the site of injury, the body is able to speed up its natural healing process and regenerate tissues faster.
Clinical Trials of PRP
One of the main reasons why PRP is not FDA approved is due to the lack of sufficient clinical trials. Clinical trials are essential to proving the safety and efficacy of a medical treatment. In the case of PRP, while there have been some clinical trials conducted, many of them are either preliminary or have small sample sizes.
Nevertheless, some clinical trials have yielded positive results. For example, a study published in the Journal of the American Academy of Dermatology found that PRP injections improved hair growth in patients with androgenetic alopecia. Another study published in Dental Traumatology found that PRP helped accelerate healing and reduce pain in patients undergoing root canal treatment.
Challenges of Conducting Clinical Trials with PRP
- Standardization: One of the challenges of conducting clinical trials with PRP is the lack of standardization in the preparation and administration of PRP. Different clinicians may use different protocols, which can make it difficult to compare results.
- Placebo Effect: Another challenge is the placebo effect of PRP. Because PRP involves injecting a person’s own blood into the affected area, it is difficult to conduct double-blind studies, which are essential to eliminating the placebo effect.
- Sample Size: Many clinical trials with PRP have small sample sizes, which can make it difficult to generalize the results to a larger population.
The Future of Clinical Trials of PRP
Despite the challenges, there is a growing interest in conducting more clinical trials with PRP. One approach that some researchers are taking is to use a standardized protocol for the preparation and administration of PRP. This can make it easier to compare results across different studies.
Additionally, some researchers are exploring the use of PRP in combination with other treatments, such as stem cell therapy. This may enhance the effectiveness of PRP and make it more appealing for regulatory approval.
Conclusion
While there is still a need for more clinical trials with PRP, the existing evidence suggests that it may be a promising treatment for a variety of conditions. With continued research and standardization, PRP may eventually receive FDA approval and become a widely accepted medical treatment.
| Clinical Trial | Condition Treated | Results |
|---|---|---|
| Journal of the American Academy of Dermatology | Androgenetic Alopecia | Improved hair growth |
| Dental Traumatology | Root Canal Treatment | Accelerated healing and reduced pain |

Risks and Side Effects
As with any medical procedure, PRP therapy comes with certain risks and potential side effects that patients should be aware of before undergoing the treatment. These risks and side effects can include:
- Pain at the injection site – This is a common side effect that can occur with any injection and typically resolves within a few days after the PRP treatment.
- Infection – While the risk is low, any time the skin is pierced there is a small risk of infection. Patients should make sure they receive PRP therapy from a reputable provider who uses sterile techniques and medical-grade equipment.
- Tissue damage – If the needle used to inject the PRP is not placed correctly, it can damage surrounding tissues, nerves, or blood vessels.
Beyond the immediate risks associated with the PRP injection itself, there are also concerns surrounding the long-term effects of the treatment. Because PRP therapy is a relatively new procedure, there is limited research available to fully understand the long-term risks and side effects of the treatment.
One specific concern when it comes to the long-term effects of PRP therapy is the possibility of increased cancer risk. While there is currently no definitive evidence to suggest that PRP therapy is linked to cancer, some experts have raised concerns that the high levels of growth factors present in PRP injections could potentially stimulate the growth of cancer cells.
It is important for patients to fully understand the potential risks and side effects associated with PRP therapy before considering the treatment. Patients should always consult with a qualified healthcare professional and discuss any concerns or questions they may have before undergoing any medical procedure, including PRP therapy.
| Risk | Description |
|---|---|
| Pain at the injection site | A common side effect that can occur with any injection and typically resolves within a few days after the PRP treatment. |
| Infection | While the risk is low, any time the skin is pierced there is a small risk of infection. Patients should make sure they receive PRP therapy from a reputable provider who uses sterile techniques and medical-grade equipment. |
| Tissue damage | If the needle used to inject the PRP is not placed correctly, it can damage surrounding tissues, nerves, or blood vessels. |
Long-term effects of PRP therapy are not yet fully understood so it is important to weigh the benefits and risks before opting for this treatment.
Comparing PRP to Other Treatments
There are various treatment options available for different medical conditions, and PRP is just one of them. To understand why PRP is not yet FDA approved, it is important to compare it to other treatments. Here are some treatment options that are commonly used:
- Steroid Injections – Steroid injections are often used to relieve pain and inflammation in the affected area. However, they only provide temporary relief and can have side effects such as joint damage and weakened tendons.
- Surgery – Surgery is an invasive procedure that is often considered as a last resort for injuries or chronic conditions. While it can be effective, it is also expensive and carries risks such as infection and prolonged recovery time.
- Physical Therapy – Physical therapy involves exercises and movements designed to improve mobility, strength, and flexibility. It can be effective for certain conditions but may take longer to see results than other treatments.
Comparing PRP to these treatment options, PRP has some advantages and disadvantages:
| Treatment | Advantages | Disadvantages |
|---|---|---|
| PRP | Non-invasive, natural, and safe. Can promote healing and tissue regeneration. | Varies in effectiveness depending on the condition and patient. Can have side effects such as pain, infection, and numbness. |
| Steroid Injections | Provide temporary relief for pain and inflammation. | Can have side effects such as joint damage and weakened tendons. Only provides temporary relief. |
| Surgery | Can be effective for certain conditions. Can provide long-term relief. | Expensive, invasive, and carries risks such as infection and prolonged recovery time. Not always successful. |
| Physical Therapy | Can improve mobility, strength, and flexibility. Can be effective for certain conditions. | May take longer to see results than other treatments. Not always successful. |
Overall, PRP is a promising treatment option for certain medical conditions, but it is important to compare and evaluate it against other treatments to understand its effectiveness and limitations. While PRP is not yet FDA approved, ongoing research and clinical trials may provide more evidence for its safety and effectiveness in the future.
FDA Approval Requirements for Medical Devices
When it comes to medical devices, the US Food and Drug Administration (FDA) has strict requirements to ensure their safety and effectiveness. These requirements include:
- Preclinical testing on animals
- Clinical testing on humans
- Review of the device’s design and manufacturing processes
- Inspection of the manufacturing facility
- Monitoring of adverse events
- Submission of a Premarket Approval (PMA) application
Each of these requirements plays a critical role in ensuring that medical devices meet the FDA’s standards for safety and effectiveness. But why isn’t PRP (Platelet-Rich Plasma) approved by the FDA?
PRP is considered a medical device by the FDA, but it is not subject to the same stringent requirements as other medical devices. This is because PRP is derived from a patient’s own blood, and is therefore considered a “blood product” by the FDA. Blood products are regulated by the FDA under a different set of rules than medical devices.
Why is PRP Not FDA Approved?
PRP is not FDA approved because it has not gone through the PMA process. The PMA process is required for medical devices that pose a high risk to patients, or that are intended to be implanted in the body for a prolonged period of time. PRP is not considered to be a high-risk medical device, and it is not implanted in the body for a prolonged period of time. Therefore, it has not been subject to the PMA process.
However, this does not mean that PRP is unsafe or ineffective. Many doctors and patients have reported positive results from PRP therapy, and it is considered to be a promising treatment option for a variety of conditions.
Conclusion
While PRP is not FDA approved, it is important to remember that this does not necessarily mean it is not safe or effective. The FDA’s approval process is designed to ensure the safety and effectiveness of medical devices, but it is not the only standard by which a treatment should be judged. Patients should always consult with a qualified healthcare provider before undergoing any type of medical treatment, including PRP therapy.
| Pros | Cons |
|---|---|
| Potentially effective treatment for a variety of conditions | Not subject to the same strict requirements as other medical devices |
| Non-invasive procedure with minimal side effects | May not be covered by insurance |
| Uses a patient’s own blood, reducing the risk of adverse reactions | Not backed by extensive clinical trials |
Overall, PRP is a promising treatment option with potential benefits for patients with a variety of medical conditions. While it is not FDA approved, patients should discuss the pros and cons of PRP therapy with their healthcare provider to determine if it is the right treatment option for their individual needs.
