Read this Medication Guide before you start taking POTIGA and each time you get a refill. There may be new information. This Medication Guide does not take the place of talking to your healthcare provider about your medical condition or treatment. If you have questions about POTIGA, ask your healthcare provider or pharmacist.
What is the most important information I should know about POTIGA?
Do not stop POTIGA without first talking to a healthcare provider. Stopping POTIGA suddenly can cause serious problems. Stopping POTIGA suddenly can cause you to have more seizures more often.
1. POTIGA can cause changes to your retina, which is located in the back of your eye and is needed for vision. These types of changes can cause vision loss.
- If a decrease in your vision happens, it is not known if it will get better.
- You and your healthcare provider should decide if the benefit of taking POTIGA is more important than the possible risk of vision loss.
- You should have a complete eye exam if you are currently taking POTIGA or before starting treatment, and then every 6 months while taking POTIGA.
- Tell your healthcare provider right away if you notice any changes in your vision.
2. POTIGA can make it hard for you to urinate (empty your bladder) and may cause you to be unable to urinate. Call your healthcare provider right away if you:
- are unable to start urinating
- have trouble emptying your bladder
- have a weak urine stream
- have pain with urination
3. POTIGA can cause changes in the color of your skin, nails, lips, roof of your mouth, and whites of your eyes or insides of your eyelids.
- The changes in color may be blue, grey-blue, or brown.
- Most changes in color have happened in people who have taken POTIGA for at least 2 years, but may happen earlier.
- It is not known if the changes in color go away after stopping POTIGA.
- Tell your healthcare provider if you notice any changes in color to your body.
4. POTIGA can cause mental (psychiatric) problems, including:
- new or worse aggressive behavior, hostility, anger, or irritability
- new or worse psychosis (hearing or seeing things that are not real)
- being suspicious or distrustful (believing things that are not true)
- other unusual or extreme changes in behavior or mood
Tell your healthcare provider right away if you have any new or worsening mental problems while using POTIGA.
5. Like other antiepileptic drugs, POTIGA 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
- attempt to commit suicide
- new or worse depression
- new or worse anxiety
- feeling agitated or restless
- panic attacks
- trouble sleeping (insomnia)
- new or worse 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
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 POTIGA?
POTIGA is a prescription medicine that is used with other medicines to treat partialonset seizures in adults with epilepsy when several other medicines have not worked well. POTIGA is used when the benefit of taking it is more important than the possible risk of vision loss.
POTIGA is a controlled substance (CV) because it can be abused or lead to drug dependence. Keep your POTIGA in a safe place to protect it from theft. Never give your POTIGA to anyone else because it may harm them. Selling or giving away this medicine is against the law.
