What happened

Pharmacies and clinics serving the Mueller neighborhood are reviewing stock and notifying patients after Teva Pharmaceuticals initiated a voluntary recall of prazosin hydrochloride capsules, a medicine commonly used to treat high blood pressure and certain prostate symptoms. Nearly 581,000 bottles are affected nationwide after testing found elevated levels of an N-nitroso prazosin impurity, according to FDA.

The agency classified the action as a Class II recall on Oct. 24, a designation that indicates use of or exposure to the product may cause temporary or medically reversible health effects, and that the chance of serious harm is remote, data from FDA shows. Prazosin is sometimes prescribed off-label to help with symptoms associated with post-traumatic stress disorder, which broadens the group of patients who may be checking their medicine cabinets in and around Mueller.

A statement from Teva said the company has notified customers by letter and that the recall remains ongoing.

Who is affected

The recall spans three strengths of prazosin hydrochloride capsules distributed nationwide. Bottles can be identified by National Drug Code (NDC), lot number, and expiration date listed on the label. The affected products are:

  • 1 mg: 181,659 bottles, NDC 0093-4067-01 and 0093-4067-10; lots 3010544A and 3010545A; expiration October 2025.
  • 2 mg: 291,512 bottles, NDC 0093-4068-01 and 0093-4068-10; multiple lots; expirations October 2025 through July 2026.
  • 5 mg: 107,673 bottles, NDC 0093-4069-01, 0093-4069-52, and 0093-4069-05; multiple lots; expirations extending into 2026.

Local pharmacies in the Mueller Market District and nearby clinics that dispense generic prazosin say they are checking inventory and contacting patients where records show a match to affected lots. “We’re asking patients to bring in their bottles so we can check the NDC and lot numbers on the spot,” a pharmacist at a Mueller pharmacy said. “If a bottle is part of the recall, we’ll coordinate with the prescriber on a safe substitution.”

Local impact

It was not immediately clear how many bottles from the recalled lots were dispensed in Mueller. Neighborhood clinicians said the priority is maintaining blood pressure control and continuity of care. “No one should stop this medication abruptly without a clinician’s guidance,” a manager at a community clinic serving Mueller patients said. “We can verify bottles, plan alternatives if needed, and set up monitoring.”

Patients in Mueller who use prazosin—whether for hypertension, urinary symptoms tied to prostate enlargement, or off-label for PTSD-related nightmares—may receive outreach calls from their pharmacy or clinic. Providers said they are triaging patients with recent blood pressure instability or multiple conditions for faster callbacks.

What to do next

According to FDA, a Class II recall warrants prompt verification and coordination, but not sudden discontinuation. Patients can take these steps:

  • Check the bottle’s NDC, lot number, and expiration date against the recall details above.
  • Do not stop prazosin on your own; abrupt changes can raise blood pressure and cause symptoms.
  • Call your pharmacist or prescribing clinician to confirm whether your bottle is affected.
  • If a switch is recommended, ask about timing, dose, and home blood-pressure monitoring.
  • Follow pharmacy instructions for returns or safe disposal; many pharmacies will accept recalled bottles for return to the distributor.

Clinics and pharmacies typically quarantine remaining stock, document patient outreach, and report any adverse events tied to recalled product, consistent with FDA recall guidance.

Why regulators acted

N-nitroso compounds, the class that includes the N-nitroso prazosin impurity found here, have been linked to cancer risk at certain exposure levels in laboratory studies. Over the past few years, regulators increased scrutiny after nitrosamine impurities were found in some blood pressure medications and other products, according to FDA. The agency’s goal is to limit exposure while maintaining treatment continuity.

The Class II label assigned on Oct. 24 reflects the FDA’s assessment that the risk of serious adverse outcomes is remote. Still, the agency and the manufacturer are asking patients to verify their bottles and work with clinicians rather than stopping therapy suddenly. Teva said customers were notified by letter and that the recall remains in effect.

Treatment alternatives

If a patient’s bottle is affected, clinicians may consider other evidence-based options for blood pressure control. Medical guidelines commonly use:

  • ACE inhibitors (such as enalapril or lisinopril)
  • Angiotensin II receptor blockers, or ARBs (such as losartan or valsartan)
  • Calcium channel blockers (such as amlodipine or diltiazem)
  • Other classes based on a patient’s conditions and prior response

Any change should be supervised by the prescribing clinician, with home blood-pressure checks and follow-up to ensure control.

The bottom line for Mueller

For now, local pharmacists and clinicians say the most important step is verification. Bring your bottle, or call with the NDC, lot number, and expiration date. Patients who rely on prazosin for hypertension, prostate symptoms, or PTSD-related sleep issues should expect guidance on substitutions only if their bottle is on the recall list. According to FDA, the recall’s Class II status means most patients can make a careful, coordinated switch without disruption if necessary.

As pharmacies in and around Mueller continue to check inventory, residents can expect more outreach this week. “Our goal is straightforward: keep blood pressure controlled and keep care on track,” the Mueller pharmacist said. “Call us before you make any changes.”
