Call 911 first if: a seizure lasts longer than 5 minutes, the person has trouble breathing or doesn’t wake up afterward, is injured, is pregnant, has diabetes, or has repeated seizures back to back. Treat these as emergencies. The guidance below is for follow-up after a first-time seizure — not for an active emergency.
A first seizure is frightening, and it raises an immediate question: what now? The good news is that a single seizure has a clear path forward, and a neurology evaluation is the most important next step. Here’s what to do in the hours and days after a first-time seizure.
Emergency vs. follow-up: when to call 911
Most brief seizures stop on their own within a couple of minutes. Call 911 right away, though, if the seizure lasts more than 5 minutes, a second seizure follows quickly, the person doesn’t regain awareness, has difficulty breathing, or is injured during the event. When in doubt, err on the side of emergency care.
What to do in the first 24–48 hours
Once the person is safe and recovered, write down what happened — how long it lasted, what it looked like, any warning signs beforehand, and what they were doing when it started. These details genuinely help your neurologist. Avoid driving until you’ve been evaluated and cleared, and try to get rest and stay hydrated.
Why a neurology evaluation matters
A neurologist works to determine why the seizure happened, whether it’s likely to recur, and whether treatment is needed. Causes range from temporary triggers — like sleep deprivation, illness, or certain medications — to underlying conditions. Sorting that out shapes everything that follows.

Tests you may need
Evaluation often includes an EEG to look at your brain’s electrical activity, and may include brain imaging. These help clarify the cause and your risk of another seizure. Our guide on what to expect during an EEG test explains the process if one is ordered.
Does one seizure mean epilepsy?
Not necessarily. Epilepsy is defined by a tendency toward recurrent seizures, and many people who have one seizure never have another. Your neurologist will explain your specific situation and what it means for you.
Booking your evaluation
After a first seizure, prompt follow-up gives you answers and peace of mind. To schedule an evaluation at Mir Neurology in Hagerstown or Cumberland, request an appointment or call (301) 797-7600 — same-week appointments are often available.
Frequently asked questions
Should I go to the ER after a first seizure?
If the seizure was prolonged, repeated, or caused injury or breathing trouble, call 911. For a single brief seizure that has stopped, you should still arrange prompt neurology evaluation — call us or your doctor.
Does one seizure mean epilepsy?
No. Epilepsy involves a tendency toward recurrent seizures. Many people who have one seizure never have another.
What tests follow a first seizure?
An EEG to assess brain activity, and sometimes brain imaging, help determine the cause and the risk of recurrence.
Can I drive after a seizure?
Avoid driving until you’ve been evaluated and cleared. Driving rules after a seizure vary, so ask your neurologist about your specific situation.
