Oseltamivir Shortage Update: February 2026

The Oseltamivir shortage continues to affect pharmacies across the United States as the 2025–2026 flu season remains active. If you've been told your pharmacy can't fill your prescription for generic Tamiflu, here's everything you need to know — updated for February 2026.

Current Status: What's in Shortage?

As of January 2026, the American Society of Health-System Pharmacists (ASHP) lists Oseltamivir capsules and oral suspension as currently in shortage. Here's what's affected:

• 30 mg capsules — multiple manufacturers on back order
• 45 mg capsules — limited availability
• 75 mg capsules — the most commonly prescribed strength; spotty availability
• 6 mg/mL oral suspension — critical for pediatric patients; significant supply constraints

Major generic manufacturers including Amneal, Teva, Alvogen, and Aurobindo have reported supply disruptions. Some cannot estimate when back-ordered products will become available.

Why Is This Happening?

The root cause is the severity of the 2025–2026 flu season. Key factors include:

• Record flu activity. The CDC has reported elevated influenza-like illness (ILI) rates across nearly all states, with this season rivaling some of the worst in the past decade.
• Surge in prescriptions. More flu cases mean more Oseltamivir prescriptions, straining a supply chain designed for average flu seasons.
• Manufacturing lead times. Generic drug production is planned months in advance. Rapid demand spikes can't be met instantly.
• Oral suspension bottleneck. The liquid form has a separate, more complex manufacturing process and has been hit especially hard.

Is Brand-Name Tamiflu Also Affected?

Brand-name Tamiflu (made by Genentech/Roche) may still be available at some pharmacies, but it's significantly more expensive — roughly $175–$200 for a treatment course without insurance, compared to $25–$55 for generic with a coupon.

Some insurance plans cover brand-name Tamiflu, but copays may be higher. Check with your pharmacy and insurer.

What Should You Do Right Now?

If you need Oseltamivir and your pharmacy is out, take these steps immediately:

1. Search nearby pharmacies. Use MedFinder to check real-time availability at pharmacies near you.
2. Call around. Stock levels vary widely. Independent pharmacies and grocery store pharmacies often have different supply lines. See our full guide on how to find Oseltamivir in stock.
3. Ask about different forms or strengths. If 75 mg capsules are out, your pharmacist may be able to dispense alternative capsule strengths or compound a suspension from capsules.
4. Discuss alternatives with your doctor. Baloxavir (Xofluza), Zanamivir (Relenza), and Peramivir (Rapivab) are all FDA-approved flu antivirals that may be available.
5. Act fast. Oseltamivir is most effective when started within 48 hours of symptom onset. Don't wait days for a restock.

When Will the Shortage End?

There's no official end date. Historically, Oseltamivir shortages ease as flu season winds down — typically by late March to April. However, the timeline depends on:

• When flu activity starts to decline
• How quickly manufacturers can fulfill back orders
• Whether any additional supply chain disruptions occur

We'll continue updating this page as new information becomes available.

CDC Guidance During the Shortage

The CDC has previously issued interim guidance during Oseltamivir shortages, recommending that providers prioritize treatment for:

• Hospitalized patients
• Patients with severe or progressive illness
• People at high risk for flu complications (elderly, pregnant women, immunocompromised individuals, young children)

If you're in a high-risk group, make sure your doctor knows — they may be able to help you access Oseltamivir through hospital or clinic supplies.
