MEDICATION GUIDE
Primidone (prim’ i done) Tablets, USP
Read this Medication Guide before you start taking primidone and each
time you get a refill. There may be
new information. This information does not take the place of talking
to your healthcare provider about your
medical condition or treatment.
What is the most important information I should know about primidone?
Like other antiepileptic drugs, primidone may cause suicidal thoughts
or actions in a very small number of
people, about 1 in 500.
Call a healthcare provider right away if you have any of these
symptoms, especially if they are new, worse,
or worry you:
•
thoughts about suicide or dying
•
attempts to commit suicide
•
new or worsening depression
•
new or worsening anxiety
•
feeling agitated or restless
•
panic attacks
•
trouble sleeping (insomnia)
•
new or worsening irritability
•
acting aggressive, being angry, or violent
•
acting on dangerous impulses
•
an extreme increase in activity and talking (mania)
•
other unusual changes in behavior or mood
Do not stop taking primidone without first talking to a healthcare
provider.
•
Stopping primidone suddenly can cause serious problems. Stopping a
seizure medicine suddenly in a
patient who has epilepsy can cause seizures that will not stop (status
epilepticus).
Suicidal thoughts or actions can be caused by things other than
medicines. If you have suicidal thoughts or
actions, your healthcare provider may check for other causes.
How can I watch for early symptoms of suicidal thoughts and actions?
•
Pay attention to any changes, especially sudden changes, in mood,
behaviors, thoughts, or feelings.
•
Keep all follow-up visits with your healthcare provider as scheduled.
•
Call your healthcare provider between visits as needed, especially if
you are worried about symptoms.
What is primidone?
Primidone is a prescription medicine used alone or with other
medicines to treat people with:
•
generalized tonic-clonic (grand mal) seizures
