How Texas PI Firms Get LOP Prescriptions Filled for Clients Anywhere in the State

LoneStar Injury Rx fills Letter of Protection prescriptions from a Texas State Board of Pharmacy licensed pharmacy in Houston and ships medication directly to the client's door in all 254 Texas counties, typically within 24 hours of receiving the LOP and prescription. The firm sends one referral; the client does not need to find a local pharmacy that will accept an LOP.

Why delivery matters more than location for LOP clients

An injured client in a Texas metro can usually find a pharmacy. Finding one that will accept a Letter of Protection is a different problem, and outside the major cities it is often impossible. The result is a client who goes without medication the treating provider ordered, a treatment record with gaps, and a damages model with pharmacy specials missing.

Direct delivery from a single LOP pharmacy solves that for every client at once. The firm sends one referral, the pharmacy verifies the prescription with the treating provider, and the medication arrives at the client's door with the same documentation whether the client is in Katy or Kermit.

How statewide LOP delivery works

LOP pharmacy service by region

Houston

Harris, Fort Bend, Montgomery, Brazoria, and Galveston counties. Our home base at 2051 Greenhouse Road: same-day processing and next-day delivery across the metro.

Dallas–Fort Worth

Dallas, Tarrant, Collin, Denton, and surrounding counties. LOP prescriptions for DFW firms ship overnight with the same documentation Houston firms receive.

Austin

Travis, Williamson, and Hays counties. Direct delivery to clients across Central Texas, including the growing corridor between Austin and San Antonio.

San Antonio

Bexar and surrounding counties. Fast LOP processing for South Texas firms with delivery to clients throughout the region.

El Paso and West Texas

El Paso, Midland, Odessa, Lubbock, and Amarillo. Distance from a metro pharmacy is not a barrier when medication ships to the client's door.

Rio Grande Valley and Coastal Bend

McAllen, Brownsville, Harlingen, Laredo, and Corpus Christi. Reliable delivery for clients who may be far from a pharmacy that will accept an LOP.

Every region receives the same attorney-ready documentation on every fill. What that documentation includes. New to Letters of Protection at the pharmacy? How an LOP pharmacy works in Texas.

Statewide Delivery Questions

Yes. Medication ships directly to the client anywhere in Texas, from Dallas–Fort Worth to the Rio Grande Valley to El Paso. There is no county we do not serve.

Prescriptions are typically dispensed within 24 hours of receiving the LOP and prescription, then shipped with tracking. Most Texas metro deliveries arrive the next business day; rural addresses may take an additional day.

Delivery requirements depend on the medication. Non-controlled prescriptions are shipped with tracking to the address the client confirms. Controlled substances follow Texas and federal shipping requirements, which your liaison will explain before the first fill.

Yes. The LOP stays on file and refills ship to the client's new address anywhere in Texas. Your firm does not need to find a new pharmacy or restart the referral.

No. Every firm in Texas uses the same referral, the same liaison model, and receives the same documentation. Only the shipping distance changes.

Yes. Rural clients are often the ones with the least access to a pharmacy that will accept a Letter of Protection. Direct delivery closes that gap.
