Total Parenteral Nutrition (TPN)
Complete IV Nutrition When the Digestive System Can't Be Used
Total Parenteral Nutrition (TPN) delivers complete nutrition directly into the bloodstream, bypassing the digestive system entirely. It's prescribed when the gastrointestinal tract can't absorb adequate nutrients, or needs complete rest to heal. Every formula contains the full range of nutrients the body requires, calculated for the individual patient.
What Is Total Parenteral Nutrition?
Pharmko provides customized Total Parenteral Nutrition (TPN) therapy delivered safely to your home. Our clinical pharmacists work directly with your care team to compound sterile, personalized nutrient formulations tailored to your unique medical needs.
TPN provides all essential nutrients your body needs:
Proteins
Amino acids for building and repairing tissue
Carbohydrates
Glucose for energy
Fats
Lipid emulsions for essential fatty acids and calories
Vitamins & Minerals
Complete micronutrients for metabolic function
Electrolytes
Sodium, potassium, calcium, and other essential minerals
Water
Hydration customized to your fluid needs
How It Works:
TPN is administered through a central venous catheter (CVC)—a thin, flexible tube placed in a large vein near your collarbone that leads directly to your heart. This allows high concentrations of nutrients to be safely delivered to your bloodstream.
Most patients receive TPN overnight for 10-14 hours while they sleep, allowing normal daily activities during the day.

Frequently Asked Questions
How Long Will I Be on TPN?
The duration of TPN therapy varies widely depending on your condition:
• Short-term (weeks to months): Post-surgical recovery, temporary bowel rest, acute illness
• Long-term (months to years): Chronic conditions like short bowel syndrome, severe Crohn's disease
• Lifelong: Permanent intestinal failure requiring ongoing nutritional support
Your physician will discuss the expected duration based on your diagnosis and treatment goals.
Can I Eat Food While on TPN?
It depends on your condition:
• Some patients can eat small amounts of food for pleasure or partial nutrition, even while on full TPN.
• Others must avoid all oral intake to allow the GI tract to heal completely.
Your care team will provide specific dietary guidelines for your situation.
What Does TPN Administration Involve?
You (or your caregiver) will be trained to:
✓ Prepare your workspace: Clean, sanitized surface away from pets and distractions
✓ Inspect the TPN bag: Check for cloudiness, particles, leaks, expiration date
✓ Warm to room temperature: Remove from refrigerator 2 hours before use (never microwave)
✓ Connect to IV pump: Follow supplier's instructions for tubing setup
✓ Start infusion: Typically runs 10-14 hours overnight
✓ Store supplies properly: Refrigerate TPN, keep supplies clean and organized
Training: A home health nurse will teach you step-by-step before your first home infusion.
Are There Side Effects or Risks?
Like any medical therapy, TPN has potential risks, which is why clinical monitoring is essential:
Common manageable issues:
• Catheter site irritation (proper care reduces risk)
• Blood sugar changes (monitored via labs, insulin may be added to TPN)
• Electrolyte imbalances (adjusted based on regular lab work)
Serious risks (rare with proper monitoring):
• Catheter-related infections (prevented through sterile technique)
• Liver complications (long-term TPN; monitored via liver function tests)
• Blood clots (managed with medications if needed)
Pharmko's clinical team monitors your labs closely and adjusts formulations to minimize risks.
Will Insurance Cover TPN?
Most insurance plans, including Medicare and Medicaid, cover TPN when medically necessary. Requirements typically include:
✓ Physician documentation of medical necessity
✓ Proof that oral/enteral nutrition is not possible
✓ Regular lab monitoring to justify ongoing therapy
Pharmko handles all prior authorizations and insurance verification for you.

Living with TPN: Your Questions Answered
What is the cost of parenteral nutrition?
TPN costs vary based on formulation complexity and duration of therapy. Most insurance plans cover TPN when medically necessary. Pharmko handles all insurance verification and prior authorization processes to maximize coverage. Out-of-pocket costs depend on your specific plan. Contact our team for a personalized insurance benefit review.
What are the different types of parenteral nutrition?
• Total Parenteral Nutrition (TPN): Complete nutrition via IV when no oral/enteral intake is possible
• Peripheral Parenteral Nutrition (PPN): Partial nutrition via smaller peripheral vein for short-term use
• Partial Parenteral Nutrition: Supplemental IV nutrition combined with some oral or enteral feeding
Pharmko specializes in TPN for home administration.
What are the benefits of parenteral nutrition?
✓ Provides complete nutrition when the GI tract cannot be used
✓ Allows the bowel to rest and heal from disease or surgery
✓ Prevents malnutrition in patients who cannot eat
✓ Can be administered safely at home, improving quality of life
✓ Customized to each patient's unique nutritional needs
What conditions require parenteral nutrition?
TPN is indicated for patients with:
• Intestinal failure or severe malabsorption
• Bowel obstruction or fistulas
• Short bowel syndrome
• Severe inflammatory bowel disease (Crohn's, ulcerative colitis)
• Post-surgical complications requiring prolonged bowel rest
• Cancer treatment side effects preventing oral intake
• Any condition where the GI tract is non-functional for >7 days
How is parenteral nutrition administered?
TPN is delivered through a central venous catheter (CVC) placed by a physician in a large vein near the collarbone. The catheter remains in place throughout therapy. At home, you connect your TPN bag to the catheter using sterile tubing and an IV pump, which controls the infusion rate. Most patients infuse overnight (10-14 hours) while sleeping.
Understanding Parenteral Nutrition
Common questions about cost, types, and how therapy is administered.
Can people on TPN still eat?
It depends on your medical condition. Some patients can eat small amounts for pleasure or to maintain some GI function, while others must completely avoid oral intake to allow bowel healing. Your physician will provide specific dietary guidelines. Even if you can eat, TPN provides the majority of your nutritional needs.
Why would a patient need TPN?
A patient needs TPN when their gastrointestinal tract is not functioning adequately to absorb nutrition, or when the GI tract needs complete rest to heal. This can result from intestinal disease, surgery complications, severe malabsorption, or conditions that prevent eating or digestion.
What is the life expectancy of a person on TPN?
Life expectancy on TPN depends entirely on the underlying medical condition, not the TPN itself. Many patients on TPN for short bowel syndrome or other chronic conditions live full, active lives for decades. Modern TPN formulations and home therapy have greatly improved long-term outcomes. Your prognosis is determined by your primary diagnosis and overall health.
How many hours does TPN last?
A typical TPN infusion runs for 10-14 hours, usually overnight while you sleep. This is called "cyclic TPN." The slower infusion rate allows your body to properly utilize nutrients and reduces the risk of metabolic complications. Some patients may require 24-hour continuous TPN depending on their condition.
For Patients and Families
Starting TPN at Home, Step by Step
From the day your physician writes the order to the rhythm you will settle into.
Your referral arrives
Your physician sends us the order, and we take it from there. We verify your insurance, confirm the details of your prescription with your care team, and call you to introduce ourselves. You will speak with a person, not a portal.
Your first delivery
Your nutrition formula arrives at your home, compounded specifically for you, along with everything you need to administer it. We coordinate the delivery around your day, not ours.
Your first infusion
A home health nurse walks you through it in person, start to finish, at your own pace. You will practice the steps together until you feel steady with them. Most people are surprised by how quickly it becomes manageable.
Your first week
The first few nights are the ones people worry about. You will have our number, and someone answers it, including at night and on weekends. We check in with you rather than waiting for you to call.
The rhythm you settle into
Deliveries arrive on a predictable schedule. Your pharmacist reviews your labs alongside your physician and adjusts your formula as your needs change. After a few weeks, most patients describe it as part of the day rather than an event in it.
For Patients and Families
Questions Patients Ask Us
The practical ones, about ordinary life on therapy. For clinical questions about duration, diet and coverage, see the sections above.
Will I be able to sleep while my infusion runs?
Most patients infuse overnight, and yes, people sleep. The pump is quiet and designed to run while you rest. It takes a few nights to get used to, and nearly everyone does.
Can I shower?
Yes. Your nurse will show you how to protect your catheter site, and you will have the supplies for it. Showering is part of a normal week on TPN.
Can I travel?
Many patients do. It takes planning around supplies, refrigeration and your schedule, and we help arrange it. Give us as much notice as you can and we will work it out with you.
Does connecting hurt?
The infusion itself does not. Once your catheter site has healed, connecting and disconnecting is not painful. Discomfort at the site is something to tell us about, not something to tolerate.
What if the pump alarms in the middle of the night?
You call us. Our line is answered around the clock by someone who can walk you through it. Most alarms have simple causes and are resolved on the phone.
Will I be able to keep working?
Many patients do, particularly with an overnight schedule that leaves the day free. Talk with your physician about what your specific situation allows.
Who answers when I call?
Someone from our team, at any hour. You will not be routed through a call center or asked to leave a message. For anything urgent or medical, call your physician or 911.
A Morning on TPN
What an ordinary Tuesday looks like
Marcus finishes his infusion around six, disconnects, and makes coffee. His pump ran while he slept, the way it has for the past eight months. He checks his phone at the kitchen table before the house wakes up. It is a Tuesday, and it looks like a Tuesday.
If You Are Caring for Someone
You're Part of This Too
Most of our calls come from patients. A good number come from the person sitting next to them. Both are welcome, and neither needs to apologize for calling.
You do not have to become a nurse
Training is designed so that the patient can manage their own therapy. You are welcome to learn alongside them, but the goal is their independence, not your second job.
Call us instead of guessing
If something looks off and you are not sure whether it matters, that is exactly the call to make. There is no such thing as bothering us, and there is no wrong hour.
Watch for your own limits
Caregiving is steady, invisible work, and it wears people down quietly. Ask your care team about respite options and support in your area. Looking after yourself is part of looking after them.
