How quickly does Valtoco (diazepam nasal spray) stop a seizure?
Valtoco works fast. In people whose seizures are already happening, it’s designed to stop an active seizure episode quickly—typically within minutes after use.
What factors can change how fast it works?
The time to stop a seizure can vary based on things like how soon Valtoco is given after seizure onset, the person’s age and seizure pattern, and whether the seizure is convulsive or progresses toward longer-lasting activity. Giving it promptly after the start of the event generally helps.
How long should you wait before getting emergency help?
If the seizure does not stop promptly after using Valtoco, or if it continues, get emergency help right away or follow the action plan your clinician gave you. (Exact timing guidance depends on the prescription instructions for the patient.)
What to do during the wait for Valtoco to take effect
While Valtoco is taking effect, keep the person safe from injury and stay with them. Do not put anything in their mouth. If breathing becomes abnormal or the seizure continues, treat it as an emergency per your care plan and local guidance.
