Here is a complete, evidence-based answer:
Midazolam Nasal Spray for Adult Seizures
The Approved Product: Nayzilam (midazolam nasal spray)
Nayzilam is the FDA-approved intranasal midazolam formulation specifically indicated for seizures. It is a 5 mg/0.1 mL single-dose nasal spray device - not the IV solution. Do NOT use midazolam IV solution intranasally in a routine clinic/home setting when Nayzilam is available, as concentration and atomization matter for absorption.
Indication: Acute treatment of intermittent, stereotypic episodes of frequent seizure activity (seizure clusters / acute repetitive seizures) that are distinct from the patient's usual pattern - approved for age 12 and older.
Dosing (Adults and Adolescents ≥12 years)
| Step | Dose | Route |
|---|---|---|
| Initial dose | 5 mg (1 spray) | Into ONE nostril |
| Second dose (if no response after 10 min) | 5 mg (1 spray) | Into the OPPOSITE nostril |
| Maximum per episode | 10 mg (2 sprays) | - |
Key Restrictions
- Do NOT give a second dose if the patient has difficulty breathing or unusual/excessive sedation during the episode
- Do not treat more than 1 episode every 3 days
- Do not treat more than 5 episodes per month
Off-Label / Emergency Use (when Nayzilam not available)
In prehospital or emergency settings where IV access is unavailable, midazolam IV solution (5 mg/mL) can be given intranasally via a mucosal atomization device (MAD):
- Adults (>40 kg): 10 mg intranasally (typically 5 mg per nostril), delivering no more than 0.5 mL per nostril
- Weight-based: 0.2 mg/kg IN, max 10 mg
- Concentration used: 5 mg/mL (not diluted) to minimize volume per nostril
This is supported by Katzung's pharmacology textbook, which notes that "in the prehospital setting, rectal diazepam, intranasal midazolam, or buccal midazolam are acceptable alternative first treatments" when IV access is unavailable.
Clinical Efficacy
A 2024 systematic review in Neurocritical Care (PMID 38580802) covering 929 adults found:
- 72.7% mean seizure termination rate after the first IN-midazolam dose
- Doses in included studies ranged from 2.5 to 20 mg per single dose
- Most common adverse effects: dizziness (23.5%), local nasal irritation (16.6%), sedation (12.7%)
- Authors conclude IN-midazolam is "promising" but note need for more uniform research
Practical Notes
- Nayzilam absorbs via nasal mucosa; onset is typically 2-5 minutes
- Patient/caregiver should be trained in advance for home use
- Always have the patient seen by their neurologist after a cluster episode
- Nayzilam is a controlled substance (Schedule IV benzodiazepine) - requires prescription
- For status epilepticus in hospital, IV/IM midazolam (10 mg IM for adults >40 kg) remains first-line, not the nasal route
Summary: For adults with known epilepsy and seizure clusters, prescribe Nayzilam 5 mg nasal spray - 1 spray in one nostril, repeat once in the other nostril after 10 minutes if needed. Max 10 mg per episode, no more than 1 episode per 3 days.

Excellent - now I have all the information needed. Let me give a comprehensive India-specific answer:
Midazolam Nasal Spray for Adult Seizures - India
What's Available in India
Nayzilam (the US FDA-approved 5 mg ready-to-use spray) is not available in India. Two practical options exist:
Option 1: Midacip Nasal Spray (Cipla) - Ready-to-Use
Midacip by Cipla is the only branded midazolam nasal spray registered in India (0.5 mg/puff). However, at 0.5 mg per puff, you would need 10 puffs to reach a 5 mg dose - this is mainly used for anxiolysis/sedation, not practical as the primary seizure rescue spray in the current market.
Option 2: MIDASIZ Nasal Spray (Centaur Pharmaceuticals) - Best Practical Option
MIDASIZ (Centaur Pharma) is a purpose-made intranasal midazolam product available in India with a dedicated seizure dosing protocol:
| Weight | Adult Dose |
|---|---|
| < 50 kg | 5 mg intranasally (split equally between both nostrils) |
| > 50 kg | 10 mg intranasally (split equally between both nostrils) |
- Dose formula: 0.1 mg/kg for adults
- Divide the dose equally between both nostrils (more surface area = better absorption)
- Concentration: 1.25 mg/0.1 mL per spray
Option 3: Midazolam Injection + MAD (Most Widely Used in Indian Practice)
When a dedicated nasal spray is unavailable, the standard Indian practice is to use midazolam injection solution (5 mg/mL) drawn into a syringe and delivered via a Mucosal Atomization Device (MAD) nozzle.
Which injection brand to use:
| Brand | Company | Concentration |
|---|---|---|
| Fulsed | Sun/Ranbaxy | 5 mg/mL |
| Mezolam | Neon Labs | 5 mg/mL |
| Midzee | Gland Pharma | 5 mg/mL |
| Midosed | Sun Pharma | 5 mg/mL |
| Shortal | Themis Medicare | 5 mg/mL |
Use the 5 mg/mL concentration (not the 1 mg/mL) to minimize volume per nostril.
Adult Dosing with MAD:
| Weight | Dose | Volume (at 5 mg/mL) | Per nostril |
|---|---|---|---|
| < 50 kg | 5 mg | 1 mL | 0.5 mL each |
| > 50 kg | 10 mg | 2 mL | 1 mL each |
| Weight-based | 0.2 mg/kg | max 10 mg | split equally |
How to administer:
- Draw up calculated volume into a 1-2 mL syringe
- Attach MAD (LMA MAD Nasal or equivalent) to syringe tip
- Tilt head back slightly
- Place MAD tip just inside one nostril, spray half the dose
- Immediately spray the other half into the other nostril
- If no response in 10 minutes, repeat dose once
Key Practical Points for India
- Use 5 mg/mL concentration only - the 1 mg/mL formulation requires too large a volume (>2 mL per nostril), which drains into throat and reduces absorption
- MAD devices (LMA MAD Nasal tip) are available from medical equipment suppliers in India
- Onset: 2-5 minutes after intranasal administration
- Monitor for respiratory depression, especially if patient received other CNS depressants
- If seizure persists >10 min after dose, escalate to IV/IM route or call emergency services
- Midazolam is a Schedule H drug in India - requires prescription
Bottom line for India: Use MIDASIZ (Centaur) if available, or draw up Fulsed/Mezolam 5 mg/mL with a MAD device. For adults >50 kg give 10 mg split between both nostrils; for adults <50 kg give 5 mg split between both nostrils.

Now I have a thorough picture. Here is a comprehensive, honest answer:
Indian Epilepsy Guidelines on Seizure Cluster Management
Honest Finding First
There is no recent dedicated Indian national guideline specifically on seizure cluster management published in the last 3-5 years. Here is what exists and what applies to Indian practice:
1. Indian Epilepsy Society (IES) - GEMIND Guidelines
The IES GEMIND guidelines (Guidelines for Epilepsy Management in India) are the primary Indian reference. They are published as chapter-wise documents on the IES/IEA website, covering:
- Classification, investigation, treatment
- Status epilepticus (Chapter 11)
- Provoked seizures (Chapter 10)
Key issue: The GEMIND guidelines predate the recent expansion of intranasal midazolam and seizure cluster-specific guidance. The IES has not published a standalone seizure cluster rescue therapy consensus to date. The guidelines broadly recommend benzodiazepines for acute seizure termination and reference intranasal midazolam as an option when IV access is unavailable, but do not give a structured seizure cluster protocol for outpatient use.
2. Most Applicable Recent Global Guideline (2024)
Pina-Garza et al., Epileptic Disorders, 2024 (PMID 38813941) - international expert consensus using modified Delphi methodology:
Key Recommendations (directly applicable to Indian practice):
| Recommendation | Detail |
|---|---|
| Define seizure cluster individually | An abnormal increase in seizure frequency vs. that patient's own usual pattern - not a fixed number |
| Prolonged seizure threshold | Focal seizure: >5 min; Absence: >2 min; Bilateral tonic-clonic: >2 min of convulsive phase |
| All patients with seizure clusters should be offered an Acute Cluster Treatment (ACT) | Strong consensus (100% agree/strongly agree) |
| Ideal rescue drug onset | Should act within 2 minutes of administration |
| Every patient should have a written Seizure Action Plan agreed with them/caregiver | - |
| Treat early - before progression to status epilepticus | Primary goal |
3. Status Epilepticus in India - What Guidelines Say
The IES and major Indian teaching hospitals follow a modified NCS/AES protocol adapted for Indian resource settings:
Out-of-hospital / pre-hospital (no IV access):
| Step | Drug | Dose (Adults) | Route |
|---|---|---|---|
| First line | Midazolam | 10 mg (>50 kg); 5 mg (<50 kg) | Intranasal via MAD or Midasiz |
| Alternative | Diazepam | 10 mg rectal | Rectal |
In-hospital:
| Step | Drug | Dose | Route |
|---|---|---|---|
| First line | Lorazepam | 4 mg IV (repeat once) | IV |
| OR | Midazolam | 0.1-0.2 mg/kg IV/IM | IV/IM |
| Second line | Levetiracetam 60 mg/kg OR Valproate 40 mg/kg OR Fosphenytoin 20 mg PE/kg | IV | |
| Refractory | Midazolam infusion, Propofol, Phenobarbital | IV infusion with ICU admission |
4. Rescue Therapy Pharmacology (Global Evidence, India-Applicable)
From Epilepsia 2022 review on rescue therapies (Gidal et al.):
| Agent | Bioavailability (IN) | T-max | Best use in India |
|---|---|---|---|
| Midazolam IN (5 mg/mL injection via MAD) | 44-83% | 10-12 min | Yes - widely available |
| Midazolam buccal (Buccolam) | 75-87% | Faster | Available in some centers |
| Diazepam rectal | 97% | Slower | Available but socially less accepted |
5. What Indian Neurologists Currently Practice (Summary)
Based on available evidence and Indian practice patterns:
- Prescribe intranasal midazolam (Midasiz by Centaur, or Fulsed/Mezolam 5 mg/mL + MAD) as the take-home rescue therapy for patients with known seizure clusters
- Action plan: Give 5-10 mg IN at seizure onset (5 mg if <50 kg, 10 mg if >50 kg), split between both nostrils
- Repeat once after 10 minutes if no response
- Call emergency services if seizure does not stop after 2 doses or lasts >30 minutes
- Treat early - do not wait for the cluster to evolve toward status epilepticus
- Document and individualize - every patient's cluster definition is unique
Bottom Line
No dedicated recent Indian guideline on seizure clusters exists. The IES GEMIND guidelines provide a broad framework but lack a specific outpatient seizure cluster protocol. The 2024 international consensus (PMID 38813941) and the 2022 rescue therapy pharmacology review are the best current evidence to guide practice. Indian neurologists should adopt intranasal midazolam (Midasiz or midazolam injection via MAD) as the standard take-home rescue therapy for adults with known seizure clusters, with an individualized written seizure action plan.
