Alternatives to Igalmi if You Can't Fill Your Prescription

If your healthcare provider has prescribed Igalmi (Dexmedetomidine sublingual film) for acute agitation but you're having trouble finding it in stock, you're not alone. Igalmi is a specialty medication with limited distribution, and sometimes it's simply unavailable when you need it.

The good news is that there are several well-established alternatives for treating acute agitation associated with schizophrenia and bipolar disorder. In this article, we'll explain what Igalmi is, how it works, and walk through the most common alternatives your provider might consider.

What Is Igalmi?

Igalmi is the brand name for Dexmedetomidine sublingual film, made by BioXcel Therapeutics. It was approved by the FDA for the acute treatment of agitation associated with schizophrenia or bipolar I or II disorder in adults.

What makes Igalmi unique is its delivery method — it's a thin film placed under the tongue or behind the lower lip that dissolves quickly. It doesn't require an injection, which can be a major advantage in acute agitation situations where a patient may be uncooperative with injections.

Igalmi comes in 120 mcg and 180 mcg strengths and costs approximately $95 to $105 per film without insurance.

How Does Igalmi Work?

Igalmi works by activating alpha-2 adrenergic receptors in the brain. This is a fundamentally different mechanism than most other medications used for acute agitation, which typically work through dopamine or GABA pathways.

By stimulating alpha-2 receptors, Igalmi:

• Reduces sympathetic nervous system activity
• Produces sedation without significant respiratory depression
• Calms agitation while allowing patients to remain arousable

This unique mechanism is why some providers prefer Igalmi — it offers calming without the deep sedation or respiratory risks associated with some alternatives.

Alternatives to Igalmi

If Igalmi isn't available, here are four commonly used alternatives for acute agitation. Each has different pros, cons, and considerations.

1. Haloperidol (Haldol)

Drug class: Typical (first-generation) antipsychotic

How it's given: Intramuscular (IM) injection or oral

How it works: Haloperidol blocks dopamine D2 receptors in the brain, reducing psychotic symptoms and agitation. It has been a go-to medication for acute agitation in emergency departments for decades.

Pros:

• Very well-studied and widely available
• Fast onset when given IM (20-40 minutes)
• Inexpensive — generic Haloperidol costs just a few dollars per dose
• Can be combined with Lorazepam and Diphenhydramine (the "B52" cocktail)

Cons:

• Requires injection (IM), which may not be ideal for all patients
• Risk of extrapyramidal symptoms (EPS) like muscle stiffness and restlessness
• Can prolong the QT interval
• Deeper sedation compared to Igalmi

2. Olanzapine (Zyprexa)

Drug class: Atypical (second-generation) antipsychotic

How it's given: Intramuscular (IM) injection or oral dissolving tablet

How it works: Olanzapine blocks both dopamine D2 and serotonin 5-HT2A receptors, producing a calming effect. The IM formulation works quickly for acute agitation.

Pros:

• Available as an IM injection and an oral dissolving tablet (Zyprexa Zydis)
• Rapid onset (15-45 minutes IM)
• Lower risk of EPS compared to Haloperidol
• Well-studied for agitation in schizophrenia and bipolar disorder

Cons:

• Must not be given with benzodiazepines (risk of excessive sedation and respiratory depression)
• Can cause significant sedation
• Risk of orthostatic hypotension
• IM form is more expensive than Haloperidol

3. Lorazepam (Ativan)

Drug class: Benzodiazepine

How it's given: Intramuscular (IM) injection, intravenous (IV), or oral

How it works: Lorazepam enhances the effect of GABA, the brain's main inhibitory neurotransmitter, producing rapid sedation and anxiolysis.

Pros:

• Very fast onset, especially IV
• Widely available and inexpensive
• Effective for agitation from multiple causes, not just psychosis
• Can be combined with antipsychotics

Cons:

• Risk of respiratory depression, especially with opioids
• Controlled substance (Schedule IV) — potential for dependence
• Can cause paradoxical disinhibition in some patients
• Does not treat underlying psychosis

4. Ziprasidone (Geodon)

Drug class: Atypical (second-generation) antipsychotic

How it's given: Intramuscular (IM) injection

How it works: Ziprasidone blocks dopamine D2 and serotonin 5-HT2A receptors, similar to Olanzapine, but with a different side effect profile.

Pros:

• Effective for acute agitation in schizophrenia and bipolar disorder
• Can be given with benzodiazepines (unlike Olanzapine IM)
• Less sedating than Olanzapine in some patients

Cons:

• Requires IM injection
• Significant QT prolongation risk — requires cardiac monitoring
• Must be given with food for oral formulation (not relevant for IM)
• Not as widely available as Haloperidol

How Do These Alternatives Compare to Igalmi?

The biggest advantage of Igalmi over these alternatives is its non-injectable delivery (sublingual film) and its unique mechanism of action that produces calming without deep sedation or respiratory depression. However, all four alternatives above are well-established, widely available, and effective for acute agitation.

Your healthcare provider will consider factors like:

• Patient cooperation and ability to take a sublingual film vs. injection
• Medical history (cardiac issues, respiratory conditions)
• Other medications the patient is taking
• Severity of agitation
• Facility formulary and drug availability

Final Thoughts

While Igalmi offers a unique non-invasive option for acute agitation, there are effective alternatives available if you can't find it. Talk to your healthcare provider about which option is best for your specific situation.
