What Is a PICC Line? How It's Placed, Cared For, and Used in Home Infusion

June 15, 2026

If you are starting home infusion therapy, there is a good chance your physician has mentioned a PICC line, or you already have one placed. PICC lines are the most commonly used IV access device for home infusion because they are reliable, relatively easy to insert, and appropriate for most therapy durations from a few days to several months.


This guide explains what a PICC line is, how it gets placed, how to care for it at home, and what warning signs to watch for throughout your therapy.


What Is a PICC Line?


PICC stands for Peripherally Inserted Central Catheter. It is a long, thin, flexible tube inserted into a vein in the upper arm, typically the basilic or brachial vein, and advanced through the venous system until the tip rests in the superior vena cava, just above the heart. This central position allows medications that would damage smaller peripheral veins (such as certain antibiotics, TPN, and chemotherapy) to be diluted by the high-volume blood flow near the heart.


Despite the word 'peripheral' in its name (referring to its insertion site in the arm), a PICC is classified as a central line because its tip is in the central venous system. Pharmko trains every home infusion patient on PICC line care before their first dose.


How Is a PICC Line Inserted?


PICC insertion is a sterile, bedside procedure typically performed by a specially trained nurse or interventional radiologist. It does not require general anesthesia or an operating room. The procedure involves:


  • Cleaning and draping the insertion site on the upper arm
  • Using ultrasound guidance to identify the target vein
  • Inserting a thin introducer needle, then threading the PICC catheter through it
  • Advancing the catheter to the correct tip position, confirmed by X-ray before use
  • Securing the catheter with a stabilization device and applying a sterile dressing


The procedure takes approximately 30 to 60 minutes and is usually performed in a hospital, infusion suite, or by a home health nurse at your residence.


Types of PICC Lines


Single-lumen PICC


Has one opening (lumen) at the tip, appropriate for single-drug infusions such as IV antibiotic therapy. Most home infusion patients use a single-lumen PICC.


Double or triple-lumen PICC


Has two or three lumens, allowing multiple medications or fluids to be infused simultaneously without mixing. Used when patients require concurrent IV therapies or frequent blood draws.


Power-injectable PICC


Rated for high-pressure injection (e.g., CT contrast). If you may need imaging studies during your therapy, your physician may specify a power-injectable PICC.


How to Care for Your PICC Line at Home


PICC line care at home centers on three daily practices:


1. Dressing changes


The transparent dressing covering the insertion site must be changed when it becomes wet, loose, or visibly soiled — typically every 5 to 7 days under normal conditions. Your Pharmko nurse performs scheduled dressing changes and teaches you or your caregiver the sterile technique. Our full guide on central line care at home covers the complete dressing change process step by step.


2. Flushing


The catheter must be flushed with saline (and sometimes heparin) before and after each infusion, and on days when no infusion occurs, to prevent clotting and maintain patency. Your nurse will specify the flush schedule and demonstrate the correct technique during your training.


3. Protecting the line


Avoid submerging the arm in water (baths, swimming pools, hot tubs). Showering is permitted with a waterproof cover over the insertion site. Avoid heavy lifting or forceful arm movements that could dislodge the catheter.


Warning Signs That Require a Call


Contact your Pharmko care team immediately if you notice any of the following:


  • Redness, warmth, swelling, or drainage at the insertion site
  • Fever or chills, especially during or after an infusion
  • Pain, numbness, or swelling in the arm above the PICC
  • The catheter appears to have moved (more of the external segment is visible)
  • Resistance when flushing, or inability to flush the catheter

Compounded medications are a routine part of modern care, but unlike mass-manufactured drugs, each one is prepared individually, which means the standards behind its preparation carry real weight. For providers who order or refer for compounded therapies, a working understanding of those standards is the clearest way to judge whether a pharmacy is safe to trust. This overview covers the standards that govern sterile compounding and what they mean for the medications your patients receive. Why Standards Matter More in Compounding A commercially manufactured drug is produced under FDA oversight in large, validated batches. A compounded medication is prepared for an individual patient, often in small quantities, sometimes because no commercial equivalent exists. That flexibility is exactly why it's clinically valuable — and why the standards around preparation exist. Without rigorous controls, the same customization that helps patients could introduce contamination or error. Our guide to our sterile compounding pharmacy describes how those controls come together in practice. The Regulatory Landscape Sterile compounding sits within a layered framework: The United States Pharmacopeia (USP) publishes the general chapters, most importantly <797> and <800>, that define how compounded preparations should be made and handled. State boards of pharmacy license and inspect pharmacies, including where they're permitted to ship. Multi-state operations must maintain licensure in each state they serve. Accreditation bodies (ACHC, NABP, PCAB) provide independent verification that a pharmacy meets recognized standards. Together, these create the accountability structure behind every compounded dose. USP <797>: Sterile Preparations USP <797> is the cornerstone standard for compounded sterile preparations. It governs the conditions and practices required to keep a preparation free of contamination, including personnel training and garbing, ISO-classified air quality and engineering controls, environmental monitoring, and beyond-use dating. For any medication infused directly into the body, <797> compliance is the baseline expectation, not a premium feature. USP <800>: Hazardous Drugs USP <800> adds a containment layer for hazardous drugs, protecting personnel, patients, and the environment from unintended exposure. It specifies containment engineering controls, PPE, and validated handling procedures for drugs identified as hazardous. When a preparation is both sterile and hazardous, it must satisfy <797> and <800> together. For the details, see our breakdown of USP <800> requirements . Accreditation: Independent Verification Standards are only meaningful if someone checks that they're being met. Accreditation from ACHC, NABP, and PCAB means a pharmacy has been inspected against national benchmarks by an outside authority. For a provider, accreditation is a shortcut to confidence: it signals that the pharmacy's claims about its processes have been independently validated. The Quality-Control Process Behind the standards is a repeatable process that governs each preparation: Pharmacist review of the prescription for appropriateness, compatibility, and dosing Preparation by trained technicians under aseptic conditions In-process and final verification by a licensed pharmacist Sterility testing or filtration validation where required This chain is what turns a standard on paper into a safe medication in a patient's hands. What This Means When You Order When you refer a patient for a compounded therapy, you're effectively extending your own standard of care into another facility. Knowing that a pharmacy is USP-compliant, accredited, and pharmacist-led lets you refer with confidence that the medication will meet the same expectations you'd hold for anything you administer yourself. If you're weighing options, our guide on how to choose a compounding partner walks through the criteria. The Pharmko Standard Pharmko compounds every TPN, IDPN, and IPN preparation in a USP <797>-compliant, ISO Class 5 cleanroom, under ACHC, NABP, and PCAB accreditation, with a licensed pharmacist reviewing and releasing each formula. For the patients who receive our preparations, many of them managing End Stage Renal Disease (ESRD), that standard is the point. Refer a Patient → · [1 (877) 540-2003]
