Sulfamethoxazole/Trimethoprim Shortage Update: What Patients Need to Know in 2026

If you've been prescribed sulfamethoxazole/trimethoprim (Bactrim, Septra, TMP-SMX) and are having trouble getting it filled, you may be wondering whether there's an official shortage. Here's a complete, up-to-date breakdown for 2026.

Is There an Official Shortage of Sulfamethoxazole/Trimethoprim in 2026?

No. As of 2026, sulfamethoxazole/trimethoprim is not listed on the FDA's Drug Shortage Database as an active shortage. TMP-SMX is one of the most widely manufactured generic antibiotics in the world, with production distributed across multiple manufacturers. The absence of a national shortage means supply is generally adequate — but it does not guarantee every pharmacy in your area has the exact form and quantity you need.

What Has Caused Past TMP-SMX Availability Issues?

While TMP-SMX has not experienced the kind of prolonged, severe shortage seen with some other medications, there have been periods of localized or form-specific scarcity — particularly for the oral suspension. Key contributing factors historically include:

COVID-era supply chain disruptions (2020–2022): Factory shutdowns and shipping delays affected virtually all generic drug supply chains, including TMP-SMX.

Oral suspension scarcity: The liquid pediatric form (Sulfatrim) has been intermittently difficult to find at many retail pharmacies, particularly during fall cold and flu seasons when ear infection demand spikes.

IV formulation shortages: The intravenous form used in hospitals for severe PCP treatment has periodically appeared on shortage lists, affecting critical care settings more than outpatient patients.

Manufacturer quality issues: FDA inspections of overseas API (active pharmaceutical ingredient) manufacturers have occasionally led to temporary supply tightening.

Current Availability by Form (2026)

TMP-SMX DS tablets (800/160 mg): Generally widely available at most pharmacies nationwide.

TMP-SMX SS tablets (400/80 mg): Generally available; less commonly prescribed than DS.

Oral suspension (Sulfatrim / SMZ-TMP suspension): Intermittently difficult to find; availability varies significantly by region and season. Call ahead or use medfinder.

IV formulation: Monitor the FDA Drug Shortage Database if you require IV TMP-SMX (hospital patients); hospital pharmacists manage this directly.

What Patients Should Do Right Now

Check multiple pharmacies.

TMP-SMX is not universally stocked in every form at every pharmacy. Chains, independents, and grocery-store pharmacies all carry different inventories.

Use medfinder to find it faster.

medfinder calls pharmacies near you and texts you which ones have your medication in stock — saving you the time and frustration of calling each pharmacy yourself.

Talk to your doctor about alternatives if needed.

If you're prescribed TMP-SMX for a UTI and your local pharmacies are genuinely out, ask your doctor if nitrofurantoin or another antibiotic is appropriate. Most providers can send an alternative prescription within the same day.

How to Stay Updated on Drug Shortages

The most reliable source for official drug shortage information is the FDA Drug Shortage Database (accessdata.fda.gov/scripts/drugshortages). You can search for any drug and see current shortage status, affected manufacturers, and any resolved shortages. The ASHP (American Society of Health-System Pharmacists) also maintains a drug shortage database with additional clinical context.

The Bottom Line for Patients in 2026

There is no active FDA shortage of sulfamethoxazole/trimethoprim in 2026. Tablets are widely available at most pharmacies nationwide. If you're struggling with a local stock gap — particularly with the oral suspension — the fastest solution is to use the right tools to find it near you rather than waiting and hoping your current pharmacy restocks.
