Eprontia

Eprontia is a prescription medicine used:

• to treat certain types of seizures (partial-onset seizures and primary generalized tonic-clonic seizures) in adults and children 2 years and older,
• with other medicines to treat certain types of seizures (partial-onset seizures, primary generalized tonic-clonic seizures, and seizures associated with Lennox-Gastaut syndrome) in adults and children 2 years and older,
• to prevent migraine headaches in adults and adolescents 12 years and older.

• Take Eprontia Oral Solution exactly as prescribed.
• Your healthcare provider may change your dose. Do not change your dose without talking to your healthcare provider.
• Eprontia can be taken before, during, or after food. Drink plenty of fluids during the day. This may help prevent kidney stones.
• Take Eprontia using a marked (calibrated) measuring device. Ask your pharmacist to recommend a measuring device and for instructions on how to measure the correct dose. Do not use a household teaspoon or tablespoon.
• If you take too much or overdose, call your healthcare provider right away or go to the nearest hospital emergency room right away.
• If you miss a single dose, take it as soon as you can. However, if you are within 6 hours of taking your next scheduled dose, wait until then to take your usual dose, and skip the missed dose. Do not double your dose. If you have missed more than 1 dose, you should call your healthcare provider for advice.
• Do not stop taking Eprontia without talking to your healthcare provider. Stopping treatment suddenly may cause serious problems. If you have epilepsy and you stop taking Eprontia suddenly, you may have seizures that do not stop. Your healthcare provider will tell you how to stop taking Eprontia slowly.

Your healthcare provider may do blood tests while you take Eprontia.

Eprontia may cause eye problems. Serious eye problems include:

• any sudden decrease in vision with or without eye pain and redness.
• a blockage of fluid in the eye causing increased pressure in the eye (secondary angle closure glaucoma).
• These eye problems can lead to permanent loss of vision if not treated.
• You should call your healthcare provider right away if you have any new eye symptoms, including any new problems with your vision.

Eprontia may cause decreased sweating and increased body temperature (fever). People, especially children, should be watched for signs of decreased sweating and fever, especially in hot temperatures. Some people may need to be hospitalized for this condition. If a high fever, a fever that does not go away, or decreased sweating develops, call your healthcare provider right away. Eprontia can increase the level of acid in your blood (metabolic acidosis). If left untreated, metabolic acidosis can cause brittle or soft bones (osteoporosis, osteomalacia, osteopenia), kidney stones, can slow the rate of growth in children, and may possibly harm your baby if you are pregnant. Metabolic acidosis can happen with or without symptoms. Sometimes people with metabolic acidosis will:

• feel tired
• not feel hungry (loss of appetite)
• feel changes in heartbeat
• have trouble thinking clearly

Your healthcare provider should do a blood test to measure the level of acid in your blood before and during your treatment with Eprontia. If you are pregnant, you should talk to your healthcare provider about whether you have metabolic acidosis. Like other antiepileptic drugs, Eprontia 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
• new or worse depression
• feeling agitated or restless
• trouble sleeping (insomnia)
• acting aggressive, being angry, or violent
• an extreme increase in activity and talking (mania)
• attempts to commit suicide
• new or worse anxiety
• panic attacks
• new or worse irritability
• acting on dangerous impulses
• other unusual changes in behavior or mood

Do not stop Eprontia without first talking to a healthcare provider.

• Stopping Eprontia suddenly can cause serious problems.
• 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.

Eprontia can harm your unborn baby.

• If you take Eprontia during pregnancy, your baby has a higher risk for major birth defects including cleft lip, and cleft palate. These defects can begin early in pregnancy, even before you know you are pregnant.
• Cleft lip and cleft palate may happen even in children born to women who are not taking any medicines and do not have other risk factors.
• There may be other medicines to treat your condition with a lower chance of birth defects.
• All women of childbearing age should talk to their healthcare providers about using other possible treatments instead of Eprontia. If the decision is made to use Eprontia, you should use effective birth control (contraception) unless you are planning to become pregnant. You should talk to your healthcare provider about the best kind of birth control to use while you are taking Eprontia.
• Tell your healthcare provider right away if you become pregnant while taking Eprontia. You and your healthcare provider should decide if you will continue to take Eprontia while you are pregnant.
• If you take Eprontia during pregnancy, your baby may be smaller than expected at birth. The long-term effects of this are not known. Talk to your healthcare provider if you have questions about this risk during pregnancy.
• Metabolic acidosis may have harmful effects on your baby. Talk to your healthcare provider if Eprontia has caused metabolic acidosis during your pregnancy.

Pregnancy Registry: If you become pregnant while taking Eprontia, talk to your healthcare provider about registering with the North American Antiepileptic Drug Pregnancy Registry. You can enroll in this registry by calling 1-888-233-2334. The purpose of this registry is to collect information about the safety of Eprontia and other antiepileptic drugs during pregnancy.

Eprontia may decrease the density of bones when used over a long period. Eprontia may slow height increase and weight gain in children and adolescents when used over a long period.

Do not take Eprontia if you are allergic to topiramate, Eprontia, or any of the ingredients in Eprontia.

Before taking Eprontia, tell your healthcare provider about all of your medical conditions, including if you:

• have or have had depression, mood problems, or suicidal thoughts or behavior.
• have kidney problems, have kidney stones, or are getting kidney dialysis.
• have a history of metabolic acidosis (too much acid in the blood).
• have liver problems.
• have weak, brittle, or soft bones (osteomalacia, osteoporosis, osteopenia, or decreased bone density).
• have lung or breathing problems.
• have eye problems, especially glaucoma.
• have diarrhea.
• have a growth problem.
• are on a diet high in fat and low in carbohydrates, which is called a ketogenic diet.
• are having surgery.
• are pregnant or plan to become pregnant.
• are breastfeeding or plan to breastfeed. Eprontia passes into breast milk. Breastfed babies may be sleepy or have diarrhea. It is not known if the Eprontia that passes into breast milk can cause other serious harm to your baby. Talk to your healthcare provider about the best way to feed your baby if you take Eprontia.

Eprontia may cause serious side effects including: See Important information

• High blood ammonia levels. High ammonia in the blood can affect your mental activities, slow your alertness, make you feel tired, or cause vomiting. This has happened when Eprontia is taken with a medicine called valproic acid (Depakote). Call your healthcare provider right away if you develop unexplained tiredness, vomiting, slowing of your thinking or reaction time, or changes in your mental activities.
• Effects on thinking and alertness. Eprontia may affect how you think and cause confusion, problems with concentration, attention, memory, or speech. Eprontia may cause depression or mood problems, tiredness, and sleepiness.
• Dizziness or loss of muscle coordination.
• Severe multiorgan reactions. Treatment with Eprontia may cause a serious allergic reaction that may affect your skin or other parts of your body such as your liver, kidneys, heart, or blood cells. This allergic reaction can be life-threatening and can cause death, particularly if it is not treated as early as possible. Contact your healthcare provider or get medical help right away if you have: blistering and peeling of your skin or skin rash fever or swollen glands that do not go away hives swelling of your face, eyes, lips, tongue, or throat sores in your mouth trouble swallowing or breathing dark urine yellowing of the skin or whites of the eyes
• Serious skin reactions. Eprontia may cause a severe rash with blisters and peeling skin, especially around the mouth, nose, eyes, and genitals (Stevens-Johnson syndrome).

Usual dose for Epilepsy Monotherapy in Adults and Pediatric Patients (10 years of age and older)

The recommended dose for Eprontia monotherapy in adults and pediatric patients 10 years of age and older is 400 mg/day in two divided doses. The dose should be achieved by titration according to the following schedule:

Usual dose for Epilepsy Monotherapy in Pediatric Patients (2 to 9 Years of Age)

Dosing in patients 2 to 9 years of age is based on weight. During the titration period, the initial dose of Eprontia is 25 mg/day nightly for the first week. Based upon tolerability, the dosage can be increased to 50 mg/day (25 mg twice daily) in the second week. Dosage can be increased by 25–50 mg/day each subsequent week as tolerated. Titration to the minimum maintenance dose should be attempted over 5–7 weeks of the total titration period. Based upon tolerability and clinical response, additional titration to a higher dose (up to the maximum maintenance dose) can be attempted at 25–50 mg/day weekly increments. The total daily dose should not exceed the maximum maintenance dose for each range of body weight.

* Administered in two equally divided doses

Usual dose for Epilepsy Adjunctive Therapy in Adults (17 Years of Age and Older)

The recommended total daily dose of Eprontia as adjunctive therapy in adults with partial onset seizures or Lennox-Gastaut Syndrome is 200 to 400 mg/day in two divided doses, and 400 mg/day in two divided doses as adjunctive treatment in adults with primary generalized tonic-clonic seizures. Eprontia should be initiated at 25 to 50 mg/day, followed by titration to an effective dose in increments of 25 to 50 mg/day every week. Titrating in increments of 25 mg/day every week may delay the time to reach an effective dose. Doses above 400 mg/day have not been shown to improve responses in adults with partial-onset seizures.

Usual dose for Epilepsy Adjunctive Therapy in Pediatric Patients (2 to 16 Years of Age)

The recommended total daily dose of Eprontia as adjunctive therapy for pediatric patients 2 to 16 years of age with partial-onset seizures, primary generalized tonic-clonic seizures, or seizures associated with Lennox-Gastaut syndrome is approximately 5 to 9 mg/kg/day in two divided doses. Titration should begin at 25 mg/day (or less, based on a range of 1 to 3 mg/kg/day) nightly for the first week. The dosage should then be increased at 1- or 2-week intervals by increments of 1 to 3 mg/kg/day (administered in two divided doses), to achieve optimal clinical response. Dose titration should be guided by clinical outcome. The total daily dose should not exceed 400 mg/day.

Usual dose for Preventive Treatment of Migraine

The recommended total daily dose of Eprontia as treatment for patients 12 years of age and older for the preventive treatment of migraine is 100 mg/day administered in two divided doses. The recommended titration rate for Eprontia for the preventive treatment of migraine is as follows:

Dose and titration rate should be guided by clinical outcome. If required, longer intervals between dose adjustments can be used.

• You should not drink alcohol while taking Eprontia. Eprontia and alcohol can affect each other causing side effects such as sleepiness and dizziness.
• Do not drive a car or operate machinery until you know how Eprontia affects you. Eprontia can slow your thinking and motor skills and may affect vision.

Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Eprontia and other medicines may affect each other causing side effects.

Especially tell your healthcare provider if you take:

• valproic acid (such as Depakene or Depakote). Can increase the risk of high ammonia in the blood which can affect your mental activities, slow your alertness, make you feel tired, or cause vomiting. Call your healthcare provider right away if you develop unexplained tiredness, vomiting, slowing of your thinking or reaction time, or changes in your mental activities
• any medicines that impair or decrease your thinking, concentration, or muscle coordination
• birth control pills (estrogen-containing or progestin-only contraceptives). Eprontia may make your birth control pills less effective and increase breakthrough bleeding. Tell your healthcare provider if your menstrual bleeding changes while you are taking birth control pills and Eprontia.
