Running out of supplies mid-therapy isn't just inconvenient, it can interrupt treatment, create pressure to improvise, and put patients in situations where they feel forced to make decisions without clinical guidance. At Pharmko, one of the most common issues we help patients proactively avoid is the "I'm almost out" call the night before a dose.
This guide gives you a practical system for tracking what you use, planning refills before you feel the pressure, and understanding how insurance timing can affect deliveries so you're never caught off guard.
Key Takeaways
- Tracking per-dose usage is the foundation of any good refill plan. You can't order the right amounts if you don't know what you're using.
- A weekly inventory check on a fixed day beats reactive reordering every time.
- Insurance prior authorizations and processing time can add days to a delivery. Planning early is the only reliable buffer.
- If a shipment arrives incomplete or damaged, don't improvise. Call before you use anything you're unsure about.
The Refill System That Works for Most Patients
Step 1: Build Your Per-Dose Inventory List
Write down every item you open and use during a single complete infusion. That becomes your baseline. From that list, you can calculate exactly how many of each item you need per week, per month, and per refill cycle.
Don't rely on memory or approximation. If you're not sure what's included in your supply shipment versus what you need to track separately,
reviewing your pump and supply setup is the right starting point.
Step 2: Pick a Weekly Inventory Day and Keep It
Choose one day per week, same day, same time, to do a 5-minute check of your supplies. Go through your list and note anything that's getting low.
The rule of thumb: when you have enough for roughly two weeks of doses, it's time to reorder. That window accounts for processing time, shipping, and any insurance-related delays without creating unnecessary stockpiling.
Step 3: Reorder Before You Feel "Low"
The moment patients feel low on supplies is almost always too late to reorder comfortably. Anticipate, don't react. Your weekly inventory check is what makes proactive reordering possible.
If you're just starting out on home infusion, ask your Pharmko coordinator during your first contact to walk you through the expected delivery cadence for your specific therapy and supplies. Our first-dose checklist is also a good reference for what to confirm before your first shipment arrives.
What to Do If a Shipment Arrives Incomplete or Damaged
Document Before You Do Anything Else
When a package arrives, open it and compare the contents against your expected list before putting anything away. If something is missing or damaged, write it down specifically, item name, quantity, what the damage looks like, and call Pharmko before using anything you're uncertain about.
Do Not Substitute
This is the most important rule. Home infusion supplies are therapy-specific. A "similar" item from a retail pharmacy is not a safe substitute. If you're missing a supply item and your dose is due, call your Pharmko care team to determine the right next step for your specific situation.
How Insurance Timing Affects Your Deliveries
Prior Authorizations Are Common, and Time-Consuming
Many specialty pharmacy medications and supplies require prior authorization from insurance before each fill or refill cycle. These approvals can take several days, and they're not always predictable. If you're managing insurance documentation and want to understand
how home infusion coverage typically works, that guide explains what to expect from authorization timelines and what information your insurer usually needs from your physician.
Build Insurance Lag Into Your Reorder Timeline
Don't assume that placing a refill request today means it ships today. Build at least 5 to 7 business days of buffer into your reorder timing when insurance authorization is required. Your Pharmko coordinator can tell you what to expect for your specific coverage.
What You Can Do Today
- Build your per-dose supply list from your most recent infusion. Write it down.
- Set a recurring weekly reminder to check inventory, same day every week.
- Ask your Pharmko coordinator what the expected delivery window is for your therapy so you can plan accordingly.
- Know what to do if your delivery is disrupted. For weather events, power outages, or situations that affect delivery timing,
your home infusion support plan should include a note on how to handle a delayed shipment.

Where should I keep refill notes, contacts, and delivery records?
