Can't find Clobazam? Learn about safe alternatives to Clobazam (Onfi) for seizure treatment, including Clonazepam, Valproic Acid, and Lamotrigine.
If you've been trying to fill your Clobazam prescription and keep running into dead ends, you may be wondering: are there other medications that could work instead?
The short answer is yes — there are several medications that your doctor may consider as alternatives. But switching seizure medications is not something you should do on your own. It requires careful medical supervision, especially because Clobazam is a benzodiazepine and stopping it suddenly can cause withdrawal symptoms and breakthrough seizures.
In this article, we'll explain what Clobazam is, how it works, and walk through the most common alternatives your doctor might recommend if you can't fill your prescription.
Clobazam (brand names Onfi and Sympazan) is a benzodiazepine anticonvulsant. It's FDA-approved as an add-on treatment for seizures associated with Lennox-Gastaut syndrome (LGS) in patients 2 years of age and older.
LGS is a severe form of epilepsy that typically begins in childhood and involves multiple seizure types that are often difficult to control. Clobazam is usually prescribed alongside other anticonvulsants to help reduce seizure frequency.
For a deeper dive into Clobazam's uses and dosing, see our guide: What Is Clobazam? Uses, Dosage, and What You Need to Know.
Clobazam is a 1,5-benzodiazepine — a slightly different chemical structure than traditional benzodiazepines like Diazepam or Clonazepam, which are 1,4-benzodiazepines. This structural difference is believed to give Clobazam a somewhat more favorable side effect profile, particularly less sedation at therapeutic doses.
It works by enhancing the activity of GABA (gamma-aminobutyric acid), the brain's main inhibitory neurotransmitter. By boosting GABA's calming effect on nerve cells, Clobazam helps reduce the abnormal electrical activity that causes seizures.

If Clobazam isn't available or isn't working well for you, your doctor may consider one of the following alternatives. Never switch or stop a seizure medication without talking to your doctor first.
Drug class: Benzodiazepine (1,4-benzodiazepine)
DEA Schedule: Schedule IV
Available as: Tablets (0.5 mg, 1 mg, 2 mg), orally disintegrating tablets
Clonazepam is the closest alternative to Clobazam. It's also a benzodiazepine used for seizure control, and it works through the same GABA-enhancing mechanism. It's FDA-approved for several seizure types, including absence seizures and myoclonic seizures.
Key differences from Clobazam:
Drug class: Broad-spectrum anticonvulsant
DEA Schedule: Not a controlled substance
Available as: Tablets, extended-release tablets, sprinkle capsules, liquid, injection
Valproic Acid is one of the most commonly prescribed medications for Lennox-Gastaut syndrome. It works through multiple mechanisms, including increasing GABA levels and blocking sodium and calcium channels in the brain.
Key considerations:
Drug class: Anticonvulsant
DEA Schedule: Not a controlled substance
Available as: Tablets, chewable dispersible tablets, extended-release tablets, orally disintegrating tablets
Lamotrigine is approved for seizures associated with Lennox-Gastaut syndrome and is widely used as a maintenance anticonvulsant. It works by stabilizing sodium channels and reducing the release of excitatory neurotransmitters.
Key considerations:
Drug class: Anticonvulsant (triazole derivative)
DEA Schedule: Not a controlled substance
Available as: Tablets (200 mg, 400 mg), oral suspension
Rufinamide is specifically FDA-approved for adjunctive treatment of seizures associated with Lennox-Gastaut syndrome in patients aged 1 year and older — making it one of the few medications with the same indication as Clobazam.
Key considerations:
If you're considering an alternative to Clobazam, here's how to approach the conversation:

Before changing medications, it's worth exhausting your options for finding Clobazam. Switching seizure medications always carries some risk, and if Clobazam is working well for you, staying on it is generally preferable.

No one should have to go without their seizure medication. If Clobazam isn't available, there are real, proven alternatives your doctor can consider — including Clonazepam, Valproic Acid, Lamotrigine, and Rufinamide. Each has its own benefits and trade-offs, and the best choice depends on your individual situation.
Work closely with your neurologist or prescriber, never stop Clobazam abruptly, and use every available resource to maintain consistent seizure control. And if you need help finding Clobazam or an alternative, Medfinder is here to help.
