Perineural Injection Therapy Training for Nurses & NPs

Perineural injection therapy (PIT) involves the subcutaneous injection of a low-concentration buffered dextrose solution (typically 5% dextrose) along the course of superficial peripheral nerves that have become chronically irritated and inflamed. The dextrose interacts with TRPV1 receptors on sensory nerve fibers, reducing neurogenic inflammation and restoring normal nerve function. This mechanism addresses the underlying neural dysfunction rather than simply masking pain.

PIT has demonstrated clinical efficacy for chronic neuropathic pain conditions including headaches and migraines, chronic neck and back pain, lateral epicondylitis, Achilles tendinopathy, knee pain, post-surgical pain syndromes, and various other chronic musculoskeletal pain conditions that have a significant neuropathic component. It is particularly valuable for patients who have not responded adequately to conventional pain treatments.

Most patients require a series of four to eight treatment sessions spaced one to two weeks apart, though significant pain reduction is often noticed after the first two to three treatments. Some chronic conditions may require additional maintenance sessions. The course teaches you how to structure multi-session treatment protocols and track clinical outcomes to guide treatment duration.

PIT has an excellent safety profile because the injections are performed subcutaneously (not deep) using a very low-concentration dextrose solution rather than corticosteroids or other medications with systemic side effects. The most common side effect is mild, temporary discomfort at injection sites. The superficial injection depth and benign injectate make PIT one of the safest interventional pain procedures available.

Traditional prolotherapy (regenerative injection therapy) uses higher-concentration dextrose solutions (typically 15-25%) injected into ligament and tendon attachments to stimulate a healing inflammatory response. Perineural injection therapy uses much lower concentrations (5%) injected subcutaneously along superficial nerve pathways to reduce neurogenic inflammation. The targets, mechanisms, and concentrations are distinctly different despite both using dextrose.

Yes, PIT integrates well with other pain management modalities including joint injections, trigger point injections, physical therapy, regenerative medicine treatments, and chiropractic care. Many practitioners use PIT as part of a comprehensive, multi-modal pain management approach that addresses both neuropathic and nociceptive pain components simultaneously.

PIT requires minimal equipment — small gauge needles (typically 27-30 gauge), sterile buffered dextrose solution, syringes, and standard injection supplies. The low equipment cost and absence of expensive imaging or specialized devices make PIT one of the most accessible interventional pain procedures to add to a practice, with virtually no barrier to entry beyond proper training.

Yes, Empire Medical Training's Perineural Injection Therapy Training is fully CME/CE accredited. You receive certification documenting your training in PIT techniques along with earned CME/CE credits applicable to license renewal and professional development requirements for your specific healthcare profession.

Perineural injection therapy involves subcutaneous injections of buffered dextrose, making it one of the lowest-risk interventional procedures available. NPs in most states can perform PIT independently or under collaborative agreements. RNs may perform PIT under physician supervision. The benign injectate and superficial injection depth place PIT among the most accessible pain procedures for nursing professionals.

Unlike corticosteroid injections that suppress inflammation or nerve blocks that temporarily interrupt nerve signaling, PIT addresses the underlying neurogenic inflammation through TRPV1 receptor modulation with low-concentration dextrose. The subcutaneous injection technique, benign injectate, and mechanism of action are fundamentally different from traditional pain management injections, making PIT a unique addition to your toolkit.

PIT is particularly valuable for patients with chronic neuropathic pain who have not responded to conventional treatments — a large and underserved patient population. Chronic headaches, neck pain, extremity pain with neuropathic features, and post-surgical pain syndromes are among the conditions that respond well. These patients are often desperate for effective treatment and become highly loyal when PIT provides relief.

Scope of practice varies by state. Nurse Practitioners (NPs) in many states have full independent practice authority including prescribing and administering injectables. Registered Nurses (RNs) typically require a collaborative or supervisory agreement with a physician. Empire's training provides the clinical certification; your ability to practice independently depends on your state nursing board regulations. Our team can help you understand the requirements in your state.

Nurses who complete procedural training can pursue roles in medical spas, dermatology practices, plastic surgery offices, pain management clinics, and regenerative medicine centers. Many NPs go on to open their own aesthetic practices. The combination of nursing clinical skills with procedural certification creates one of the most in-demand professional profiles in healthcare today.

Empire Medical Training's courses are CME/CE accredited through the ACCME, and the credits are recognized by state nursing boards nationwide for continuing education and license renewal purposes. The certification documents your hands-on training competency and can be presented to employers, credentialing committees, and malpractice insurance providers.
