What does “limited distribution” mean for Lonsurf?
Lonsurf (trifluridine/tipiracil) is described as having limited distribution because it is not stocked through typical retail channels everywhere. Instead, it’s commonly supplied through a restricted network (such as specialized pharmacies and/or designated dispensing providers) to manage fulfillment and ensure patients and prescribers can access the product consistently.
Why are some oncology drugs like Lonsurf limited to certain pharmacies?
Limited distribution usually happens for operational or compliance reasons, such as:
- controlling inventory and reducing diversion or incorrect handling
- ensuring only approved sites dispense the product
- supporting patient assistance, insurance navigation, and required documentation workflows
How can patients or clinics get Lonsurf if it’s not widely distributed?
In practice, access typically works like this:
- prescribers send the prescription to a specialty/distribution-designated pharmacy
- the pharmacy verifies insurance/prior authorization needs (where required)
- the medication is dispensed directly to the patient or clinic per the pharmacy’s workflow
If you’re trying to get it now, the fastest route is usually to ask the prescriber’s office or your insurer which “limited distribution” pharmacy you must use for Lonsurf.

What should you do if your local pharmacy says it can’t order Lonsurf?
Ask for one of the following:
- the name of the limited/distribution-designated specialty pharmacy that supplies it in your area
- an alternate dispensing pathway your clinic uses (often via a specialty pharmacy partnership)
- whether your insurer requires a specific in-network pharmacy for Lonsurf
If you tell me your country/state (and whether you mean availability at a retail pharmacy vs. insurance network rules), I can narrow down what “limited distribution” likely means in your specific situation.
