How Much Does a Dog Seizure Workup Cost? A $195 Neurology Exam, a $3,000 to $4,000 MRI and Spinal Fluid Package, and Epilepsy Medication Prices
A first seizure is frightening, and the bill that follows is a second shock. Public price pages from veterinary hospitals show how large the bill can get: $195 for a neurology exam at the University of Missouri, then $3,000 to $4,000 if the neurologist orders an MRI and a spinal fluid test. The medication that comes after is cheaper per pill but never really ends. This guide reads those hospital pages and a pharmacy price list on October 20, 2026, and lays the costs out so you can ask for an estimate before you agree to anything.
The first bill: a neurology exam
The University of Missouri Veterinary Health Center lists its initial neurologic exam and evaluation at $195. That is a consultation fee only. The page says the exam comes first and that the neurologist then tells you whether higher-level imaging is recommended. Treat $195 as the entry ticket, not the total.
The big line: an MRI and spinal fluid package
Missouri's page puts MRI or CT at $3,000 to $4,000. It says that price includes the imaging, the anesthesia, any pre-anesthetic blood work the doctor feels is necessary, any radiographs the doctor feels are necessary, and a spinal fluid tap with testing of the fluid. The page also states that prices are evaluated annually and are subject to change.
By my arithmetic, the exam plus the package comes to $3,195 to $4,195. Our guide to pet MRI and CT scan costs explains why anesthesia and the specialist's fee sit inside that single number.
What the same workup cost at Illinois, and how it moved
The University of Illinois Veterinary Teaching Hospital published the cost of a workup in two documents. A November 2021 clinical trial notice described a workup of bloodwork, MRI, general anesthesia, and spinal fluid collection and analysis as totaling approximately $2,300 to $2,500. A 2023 flyer for another epilepsy study described the same bundle as approximately $3,000 to $3,500.
Those are two different documents, but by my arithmetic the range rose by roughly 30% at the low end and 40% at the high end in about two years. That is a reason to treat any older number you read online with caution.
Research studies can cover the workup, with conditions
Both Illinois documents were recruitment notices. In them, the study covered the whole workup for dogs that met the inclusion criteria, which included an age of first seizure between 6 months and 6 years, normal physical and neurologic exams, and no current medications. The 2023 flyer adds that if a dog is excluded at any point, the client is responsible for 50% of the total bill and the study covers the other 50%. On a $3,000 to $3,500 workup, that is about $1,500 to $1,750 by my arithmetic.
These notices describe studies that were open when they were written. They may be closed now, and eligibility is decided by the hospital. If you live near a veterinary college, ask whether any epilepsy study is enrolling. Our guide to charity grants for vet bills covers other ways to reduce a large bill.
Daily medication: prices from one online pharmacy
Medication cost depends on which drug and which dose your veterinarian chooses, so this guide gives listed prices and does not estimate a monthly total. Jeffers Pet's seizure and epilepsy collection page showed these prescription listings on October 20, 2026. Each listing gives a price range, which appears to reflect different pack sizes, and the page does not say which price belongs to which size:
- Levetiracetam (generic) 250 mg tablets: $0.14 to $25.99
- Levetiracetam extended-release 750 mg tablets: $0.69 to $35.99
- Phenobarbital (Fidoquel) 16.2 mg tablets: $0.21 to $32.99
- Phenobarbital elixir, 30 ml: $3.79 to $37.49
- K-BroVet (potassium bromide) 250 mg chewable, single tablet: $0.56 to $1.09
- KBroVet-CA1 chewable tablets, 60-tablet bottle: $34.65 to $67.70
- Zonisamide (generic) 50 mg capsules: $0.19 to $19.99
The low numbers are single-unit prices and the high numbers look like full bottles. For the 60-tablet bottle, $34.65 to $67.70 works out to about $0.58 to $1.13 per tablet by my arithmetic. Whether a month costs $15 or $150 depends on tablets per day, which only your veterinarian can set.
Look at what you are paying for. The same page lists generic levetiracetam, a branded chewable potassium bromide product, and a liquid phenobarbital. Ask the clinic whether the prescription can be filled at a human pharmacy or an online pet pharmacy, and ask for a written prescription so you can compare. Our guide to filling a pet prescription outside the clinic walks through the comparison. The page labels the phenobarbital elixir C-IV, a controlled-substance schedule, so expect a valid prescription to be required there.
The costs that keep returning
Hospital pages describe the diagnostic package, not the years afterward. Illinois's 2021 notice states that one-third of dogs with idiopathic epilepsy are pharmacoresistant and remain poorly controlled despite appropriate drug therapy. In plain cost terms, that means some owners go back to the clinic to adjust or add medication, and each change can come with follow-up visits and blood tests. None of the pages above prices those follow-ups, so ask the clinic for a line-by-line estimate of the first year.
Pet insurance: the pre-existing rule decides most claims
If your dog already has a policy, check whether it was in force before the first seizure and whether it has an exam-fee or prescription benefit. If you are shopping after a seizure, the pre-existing condition rule is the main obstacle. We explain it in our cancer coverage guide, and the same logic applies here. Pet insurance policies differ widely, so read your own policy wording rather than relying on a general rule.
Questions to ask before you approve a workup
- Is this a written estimate, and does it include anesthesia, bloodwork and the spinal fluid test?
- What follow-up visits and blood tests should I budget for in the first year?
- Can I fill the prescription outside the clinic, and will you write it?
- Is any research study enrolling that would cover part of the workup?
Fees come from the Missouri, Illinois and Jeffers Pet pages read on October 20, 2026, and change often, so confirm them with the hospital or pharmacy. Hospital prices are for those hospitals only; private specialty clinics in your area may charge more or less.
