Provider Briefing: Ddavp (Desmopressin) Supply Disruption in 2026

Desmopressin acetate — marketed as DDAVP, Stimate, Nocdurna, and Noctiva — has faced persistent supply challenges since 2023. As a prescriber, you've likely fielded calls from patients unable to fill their prescriptions, or encountered formulary limitations in the inpatient setting. This article provides a comprehensive overview of the current shortage landscape, prescribing considerations, and practical tools to help your patients maintain access.

Shortage Timeline

The supply disruption for Desmopressin products has evolved over several phases:

• Mid-2023: The FDA first listed Desmopressin Injection (4 mcg/mL) on the Drug Shortages database. Initial cause cited: manufacturing delays at a primary production facility.
• Late 2023 – 2024: The injectable shortage deepened, with hospital pharmacies reporting difficulty maintaining adequate stock for perioperative and hematologic use. Some institutions implemented conservation protocols.
• 2024 – 2025: Retail pharmacy shortages of oral and nasal Desmopressin emerged, driven partly by demand displacement from the injectable shortage and partly by generic manufacturer consolidation. Stimate Nasal Spray (1.5 mg/mL) became particularly difficult to source.
• Early 2026: Injectable supply remains inconsistent. Generic oral tablets (0.1 mg, 0.2 mg) are generally available but subject to regional variation. Nasal formulations remain supply-constrained.

Prescribing Implications

The shortage has several practical implications for prescribers across specialties:

Endocrinology (Central Diabetes Insipidus)

For patients with central DI, Desmopressin remains the standard of care with no true therapeutic equivalent. When the preferred formulation is unavailable:

• Formulation substitution: Oral tablets, nasal spray, and sublingual tablets contain the same active ingredient but have significantly different bioavailabilities. When switching a patient from intranasal to oral Desmopressin, the oral dose is typically 10–20 times the intranasal dose (e.g., 10 mcg intranasal ≈ 0.1–0.2 mg oral). Close monitoring of fluid balance and serum sodium is essential during transitions.
• Dose titration: Individual response varies. Start at the lower end of the equivalent range and titrate based on urine output and serum sodium levels.
• Monitoring: Check serum sodium within 2–3 days of any formulation change, then weekly until stable.

Hematology (Hemophilia A, Von Willebrand Disease)

For patients using DDAVP or Stimate as first-line therapy for mild hemophilia A or Type 1 von Willebrand disease:

• Factor concentrates as backup: Ensure patients have a contingency plan with factor VIII concentrates (e.g., Advate, Eloctate) or von Willebrand factor concentrates (e.g., Humate-P, Vonvendi) in case Desmopressin is unavailable before a procedure or bleeding episode.
• Tranexamic Acid: For minor bleeding or dental procedures, oral Tranexamic Acid (Lysteda, 1,300 mg TID for up to 5 days) can be used as adjunctive or standalone therapy.
• Stimate availability: The 1.5 mg/mL concentration nasal spray (Stimate) is the most supply-constrained formulation. If prescribing for bleeding disorder management, confirm availability before the patient needs it. Consider pre-procedural IV Desmopressin (0.3 mcg/kg) as an alternative route.

Urology/Primary Care (Enuresis and Nocturia)

For bedwetting and nocturia, the clinical urgency is lower than for DI or bleeding disorders, providing more flexibility:

• Generic oral Desmopressin at 0.2 mg bedtime remains the most available and cost-effective option for enuresis
• Nocdurna (sublingual Desmopressin) for nocturia is generally available but expensive (~$400–$500/month). Insurance often requires step therapy through generic oral Desmopressin first.
• Alternative agents: Anticholinergics (Oxybutynin), behavioral interventions, and bedwetting alarms can serve as bridge therapy or alternatives

Current Availability Picture

As of early 2026, availability by formulation:

• Generic Desmopressin tablets (0.1 mg, 0.2 mg): Generally available. Some regional spot shortages persist. Multiple generic manufacturers are active.
• Brand-name DDAVP tablets: Limited availability. Most prescriptions are dispensed as generic.
• DDAVP Nasal Spray (10 mcg/spray): Supply constrained. Generic nasal sprays are available from limited manufacturers.
• Stimate Nasal Spray (150 mcg/spray): Most supply-constrained formulation. Consider IV route as alternative.
• Nocdurna sublingual tablets: Available. High cost barrier for patients without coverage.
• Desmopressin Injection (4 mcg/mL): Intermittently available. Hospital pharmacy allocation may be limited.

Cost and Access Considerations

Cost varies dramatically by formulation, affecting patient adherence and access:

• Generic oral tablets: $15–$60/month (most affordable option)
• Brand DDAVP nasal spray: $300–$500
• Stimate: $3,000–$5,000+
• Nocdurna: $400–$500/month

For patients facing cost barriers, discount programs (GoodRx, SingleCare), the Ferring Patient Assistance Program (for brand products), and generic substitution can significantly reduce out-of-pocket expense.

Tools and Resources for Providers

Several tools can help you and your patients navigate the shortage:

• Medfinder for Providers: Real-time pharmacy inventory search. Help patients locate Desmopressin in stock near them without calling multiple pharmacies.
• FDA Drug Shortage Database: Official source for shortage status updates and estimated resolution dates
• ASHP Drug Shortage Resource Center: Regularly updated clinical guidance for managing drug shortages in institutional settings
• Ferring Pharmaceuticals Medical Affairs: Contact for supply updates on DDAVP and Nocdurna brand products

Looking Ahead

Several factors suggest gradual improvement in Desmopressin supply:

• New generic entrants: FDA approvals of additional generic Desmopressin products should increase manufacturing capacity and competition
• Manufacturing capacity expansion: Existing manufacturers have reported investments in production capacity, though these take 12–18 months to materialize
• Demand stabilization: As the injectable shortage resolves, the displacement demand on oral/nasal formulations should ease

However, the structural factors (manufacturer consolidation, complex production requirements for the nasal and injectable forms) suggest that spot shortages may persist throughout 2026 for certain formulations.

Final Thoughts

The Desmopressin supply disruption requires proactive management from prescribers. Key takeaways:

1. Know the formulation landscape — dose equivalencies matter when switching routes
2. Have contingency plans — especially for hematology patients who may need Desmopressin urgently
3. Leverage real-time tools — Medfinder for Providers can save your staff time and your patients frustration
4. Monitor serum sodium — especially when switching formulations; hyponatremia risk is the primary safety concern
5. Stay informed — check FDA and ASHP databases regularly for shortage updates
