What was recalled?
This recall covers Tirzepatide/Niacinamide 2mL vial (40 MG per Vial) Inj 20mg/2mg/mL, with approximately 64 vials affected. The company behind the recall is Houston Rx LLC, based in Houston, TX. The FDA describes the product as: “Tirzepatide/Niacinamide 2mL vial (40 MG per Vial) Inj 20mg/2mg/mL, RX Only, Houston RX LLC, 15430 Vantage Parkway E STE 220, Houston, TX 77032.”
Why was Tirzepatide/Niacinamide 2mL vial (40 MG per Vial) Inj 20mg/2mg/mL recalled?
According to the FDA, the stated reason for the recall is: “Lack of assurance of sterility.” In plain terms, this recall relates to a sterility or contamination concern.
Sterile medicines, such as injectables and eye drops, must be completely free of microorganisms and stray particles. This recall means that sterility could not be assured or that contamination was found or suspected. Using a non-sterile product of this kind can cause infections, which is why these recalls are treated seriously.
What should you do?
If you think you may have bought Tirzepatide/Niacinamide 2mL vial (40 MG per Vial) Inj 20mg/2mg/mL, compare it against the product description and identifying codes (Lot# TZN-080326-20/2-2, Beyond Use Date: 12/01/2026.) before using it. This recall is currently listed as ongoing.
The general guidance for a matching product is to stop using it and follow the instructions in the official FDA recall notice, which may include a repair, replacement, refund, or safe disposal. When in doubt, contact Houston Rx LLC or your local health authority.
