What Is Valtoco (Diazepam Nasal Spray)?
Valtoco is a brand-name, FDA-approved rescue medication used for the short-term treatment of frequent seizure activity, commonly known as seizure clusters or acute repetitive seizures. Its active ingredient is diazepam, a benzodiazepine that works by enhancing the effects of gamma-aminobutyric acid (GABA), an inhibitory neurotransmitter in the brain. By boosting GABA's activity, Valtoco slows down excessive brain nerve firing that can lead to seizure activity.
Administered as a pre-filled, single-use nasal spray, Valtoco offers a convenient and non-invasive alternative to older methods like rectal gels. This ease of use allows trained caregivers to administer the medication quickly and discreetly outside of a hospital setting, helping to terminate a seizure cluster and potentially reduce emergency room visits. It is approved for use in patients with epilepsy aged two years and older.
Why Isn't There a Generic Valtoco Yet?
The absence of a generic Valtoco is due to two main factors: patent protection and market exclusivity. The manufacturer, Neurelis, holds multiple patents covering the specific formulation, drug delivery technology (Intravail®), and method of use for Valtoco. While the active ingredient, diazepam, has been available for decades, the specific nasal spray formulation and its technology are protected by intellectual property laws.
- Patent Protection: A brand-name drug manufacturer is granted patents for its product, which provide a period of market exclusivity—typically 20 years from the patent filing date. A generic version cannot be legally sold during this time unless a patent is successfully challenged. Some Valtoco patents are active until at least 2029, with others expiring later, potentially extending its exclusive market presence.
- Market Exclusivity: The FDA may grant additional exclusivity periods to incentivize the development of certain drugs, such as orphan drugs for rare diseases. Valtoco received orphan drug exclusivity for its clinically superior formulation, further delaying the introduction of generic competition.
Only after these patents and exclusivities expire can other drug manufacturers legally produce and market a generic diazepam nasal spray. One manufacturer, Padagis, has filed an Abbreviated New Drug Application (ANDA) with the FDA to produce a generic, but litigation is ongoing, and they have indicated they will wait for patents to expire.
Alternatives to Valtoco
While awaiting a generic, several alternative rescue medications and formulations of diazepam are available. These options can be discussed with a healthcare provider to determine the best choice based on patient needs and preferences.
Other Diazepam Formulations
- Diastat (Diazepam Rectal Gel): For many years, Diastat was the only FDA-approved option for at-home seizure rescue, and it is available in generic form. It has a similar mechanism of action to Valtoco, but the rectal administration route can be less convenient and perceived as less dignified by patients and caregivers.
Alternative Nasal Rescue Medications
- Nayzilam (Midazolam Nasal Spray): Nayzilam is another FDA-approved nasal spray rescue medication for seizure clusters, though it uses a different active ingredient, midazolam. Midazolam is also a benzodiazepine but has slightly different characteristics from diazepam, including a potentially faster onset of action but a shorter duration. Nayzilam is also currently only available as a brand-name product and is approved for patients 12 years of age and older.
Off-Label and Compounded Formulations
In some cases, healthcare providers might recommend off-label or compounded medications, such as using a generic midazolam formulation with a nasal atomizer, although this is less common now with the availability of approved products like Valtoco and Nayzilam.

Side Effects | Nasal discomfort, headache, sleepiness | Rectal irritation, sleepiness | Nasal discomfort, throat irritation, sleepiness |
Cost-Saving Options for Valtoco
Because there is no generic option, the high cost of brand-name Valtoco can be a concern for patients. Several resources are available to help manage expenses:
- Manufacturer Savings Cards: Neurelis, the manufacturer, offers a copay card program for commercially insured patients that can significantly lower out-of-pocket costs.
- Patient Assistance Programs: For eligible, uninsured, or underinsured patients, Neurelis may offer patient assistance programs to provide Valtoco at low or no cost.
- Insurance Coverage: Most insurance plans, including Medicare and commercial plans, cover Valtoco, but coverage details and copays can vary. It is important to confirm with your insurance provider whether prior authorization is needed.
- Third-Party Coupons: Websites like GoodRx provide coupons that can reduce the cash price of Valtoco, sometimes significantly.
The Future of Generic Diazepam Nasal Spray
The eventual availability of a generic diazepam nasal spray hinges on the expiration or invalidation of Valtoco's patents. With patent protection lasting in some cases until 2032, a generic equivalent may not be available for several years. However, the landscape could shift if legal challenges are successful or if new technologies are developed that bypass existing patents.
Conclusion
In summary, despite the availability of generic diazepam in other forms, there is currently no generic Valtoco (diazepam nasal spray) on the market due to patent protection and market exclusivity. For patients and caregivers seeking a more affordable option, alternatives such as generic Diastat (diazepam rectal gel) or the brand-name Nayzilam (midazolam nasal spray) can be considered in consultation with a healthcare provider. Several cost-saving programs and coupons also exist to help manage the cost of the brand-name product. Understanding these options is essential for making informed decisions about epilepsy rescue medication while waiting for a generic diazepam nasal spray to become available.
