Looking for an oxcarbazepine coupon? Oxcarbazepine is the low-cost generic version of Trileptal and Oxtellar XR, an anticonvulsant (antiepileptic) FDA-approved to treat partial-onset (focal) seizures.

What is oxcarbazepine and how does it work?
Oxcarbazepine is an anticonvulsant (antiepileptic) medication in the carboxamide class. It works as a sodium channel blocker, calming the overactive electrical signaling in the brain that can lead to seizures. It is FDA-approved for the treatment of partial-onset (focal) seizures. The immediate-release form (sold under the brand Trileptal) can be used on its own or added to other seizure medicines in adults and children, and the extended-release form (Oxtellar XR) is approved for patients 6 years and older.
Oxcarbazepine is also prescribed by some clinicians for other conditions, including mood stabilization in bipolar disorder, trigeminal neuralgia, and nerve pain. Your provider will decide whether oxcarbazepine is appropriate for your situation.
How much does oxcarbazepine cost without insurance?
Oxcarbazepine is available as a generic, which typically keeps the cash price low compared with the brand-name versions. Even so, generic prices are not the same everywhere; the same prescription can cost noticeably more at one pharmacy than at another down the street. That is why it pays to compare before you fill.
Rx.com checks prices across more than 60,000 pharmacies to help you find the best deal near you. Enter your ZIP above to see today's price and print or show your free coupon at the pharmacy. If you are prescribed the brand-name extended-release product, the manufacturer of Oxtellar XR offers a co-pay savings program; terms and eligibility vary, so check the official details at oxtellarxr.com/co-pay-savings-program.
Oxcarbazepine vs. related seizure medications
Oxcarbazepine is closely related to carbamazepine but is a distinct medicine with a somewhat different tolerability profile. Because the two are chemically similar, people who have had an allergic reaction to carbamazepine may also react to oxcarbazepine (cross-reactions occur in roughly 25 to 30 percent of cases), so tell your provider about any past reactions.
Other commonly prescribed antiseizure medicines include lamotrigine and levetiracetam. The right choice depends on your seizure type, other health conditions, and how you tolerate the medicine. Whichever you are prescribed, you can compare prices for it on Rx.com by entering your ZIP above.
Oxcarbazepine safety and side effects
Common side effects of oxcarbazepine involve the central nervous system and include drowsiness, dizziness, and problems with concentration or coordination. More serious concerns your provider will watch for include low blood sodium (hyponatremia), which is most likely in the first 3 months of treatment, and rare but serious skin reactions such as Stevens-Johnson syndrome and DRESS. The risk of severe skin reactions is higher in people who carry the HLA-B*1502 gene variant, which is more common in people of Asian ancestry; genetic testing before starting is recommended for those at risk. Like other antiepileptics, oxcarbazepine may increase the risk of suicidal thoughts or behavior in a small number of people.
Oxcarbazepine can also reduce the effectiveness of hormonal birth control and may pose a risk to a developing baby during pregnancy. This is general information, not medical advice. Talk with your doctor or pharmacist about your full history, any needed blood tests, and any symptoms before starting or stopping this medication.
