Rifampin Shortage Update: What Patients Need to Know in 2026

If you're a patient relying on rifampin — or a family member helping someone navigate tuberculosis treatment — the current supply situation can be alarming. This article provides a clear, up-to-date summary of the rifampin shortage as of mid-2026, explains what it means for you, and outlines the steps you can take today.

Rifampin Shortage Status: June 2026

According to FDA shortage database records updated June 2026, the current situation is as follows:

Rifampin injection (600 mg/10 mL) — Sanofi/Rifadin IV: PERMANENTLY DISCONTINUED. Sanofi has exited this market entirely. Initial posting was February 17, 2021.

Rifampin injection (600 mg/10 mL) — Mylan Institutional (Viatris): CURRENT SHORTAGE due to shipping delay. Next release expected July 2026. Check wholesalers for existing inventory.

Rifampin oral capsules (150 mg, 300 mg): NOT currently listed in the FDA shortage database. Generally available at retail pharmacies, though local stock-outs can occur.

Why Does the Rifampin Injection Shortage Matter So Much?

Rifampin is not just any antibiotic — it is the cornerstone of tuberculosis treatment worldwide. The World Health Organization (WHO) includes rifampin on its Essential Medicines List, and the CDC recommends it as a foundational drug in every standard TB regimen.

The injectable form is critical for:

Patients who are too ill or unable to swallow oral medications

Critically ill or hospitalized TB patients (e.g., TB meningitis)

Patients with severe gastrointestinal conditions that limit oral drug absorption

For these patients, having no IV rifampin option can directly affect clinical outcomes.

Historical Context: How Long Has This Been Going On?

The rifampin injection shortage is not new. The Sanofi product was first posted as a shortage/discontinuation item in February 2021 — meaning the injectable supply crisis has been ongoing for over five years. The Mylan/Viatris product has remained the sole commercial source but has itself been affected by quality and shipping issues along the way.

Additionally, in August 2020, the FDA identified nitrosamine impurities (specifically 1-methyl-4-nitrosopiperazine, or MNP) in some rifampin samples. While no recalls have been issued, the ongoing investigation into these impurities has added complexity to manufacturing processes and contributed to supply instability.

What Does This Mean If You Take Oral Rifampin?

If you are an outpatient taking rifampin capsules for TB or latent TB, your situation is generally more manageable:

Oral rifampin capsules are not in a formal FDA shortage as of mid-2026.

Multiple generic manufacturers produce 150 mg and 300 mg capsules, providing more supply redundancy than the injectable.

Local pharmacy stock-outs can still occur and are frustrating — but they typically resolve within days as inventory is replenished.

What Can Patients Do Right Now?

Do NOT stop your medication. Stopping rifampin mid-treatment is dangerous and can cause drug resistance.

Contact your local TB clinic. Public health TB clinics often have dedicated medication supplies and can help bridge any gap.

Tell your doctor immediately if you cannot fill your prescription. They may be able to provide samples, work with hospital pharmacies, or discuss alternative regimens.

Try multiple pharmacies. Stock varies significantly between pharmacies even in the same area.

Use medfinder to locate stock near you. medfinder contacts local pharmacies on your behalf and texts you results — no hold music, no guessing.

Looking Ahead: Will the Shortage Resolve?

The Viatris rifampin injection supply is expected to improve in July 2026. However, the permanent exit of Sanofi means the U.S. injection market now depends entirely on a single manufacturer — a structural vulnerability that puts patients at ongoing risk of future shortages. Unless additional manufacturers enter the injectable market, this fragility will persist.

For oral capsules, the outlook is more stable. But patients and providers should keep an eye on the FDA Drug Shortage Database for any new developments.
