How long does Oxcarbazepine stay in your body?

The elimination half-life of oxcarbazepine is about 2 hours (immediate-release tablets and oral suspension) — the time it takes the body to clear about half of it. As a rule of thumb, a medicine is mostly gone after roughly 4 to 5 half-lives, though this varies from person to person with age and kidney or liver function. The parent drug's 2-hour half-life is misleading on its own: oxcarbazepine is rapidly converted to its active metabolite MHD (10-monohydroxy derivative), which carries most of the anti-seizure activity and has a half-life of about 9 hours. In severe kidney impairment (creatinine clearance under 30 mL/min) MHD's half-life roughly doubles, to about 19 hours, with a 2-fold increase in exposure. In adults 60 to 82 years old, MHD peak levels and exposure ran 30% to 60% higher than in adults 18 to 32, an effect the label attributes to age-related decline in creatinine clearance rather than age itself. Mild-to-moderate liver impairment did not change the pharmacokinetics of either oxcarbazepine or MHD. The extended-release form differs: in Oxtellar XR studies the elimination half-life of oxcarbazepine was 7 to 11 hours and MHD 9 to 11 hours, reflecting the slower release rather than slower clearance.

Frequently asked questions

What does Oxtellar XR treat?

Oxtellar XR (Oxcarbazepine) may be used to treat partial epilepsies, based on NIH RxClass drug-classification data (conditions a drug may treat — not a verbatim copy of the FDA-approved label). This is general reference, not medical advice.

How does Oxtellar XR work?

Oxtellar XR is a anti-epileptic agent. Anti-epileptic (anticonvulsant) drugs calm the abnormal, excessive electrical activity that triggers seizures. They do this by stabilizing overactive sodium or calcium channels in nerve cells, boosting the brain's natural calming chemical GABA, or dampening excitatory signals, which makes nerves less likely to fire uncontrollably.

How is Oxtellar XR rated?

pharmaranks gives Oxtellar XR a composite score of 3.6 out of 5, currently based on 1 weighted source (FDA regulatory recall-safety data weighted highest). See our methodology at /how-we-rate.

How much does Oxtellar XR cost?

Nobody can tell you what you will pay — your price is set by your insurer's formulary, your deductible and the pharmacy's markup, and none of those are published. What IS published is what the pharmacy paid to acquire it: about $5.03 for 30, per the CMS NADAC survey. Treat that as the floor, not the quote — ask the pharmacist for the cash price as well as your copay, because for cheap generics the cash price often wins. Pharmacies pay less for a same-class option, Mysoline — about $2.89 on the same basis.

Is there a coupon or discount for Oxtellar XR?

pharmaranks is an independent ratings site, not a pharmacy — we don't issue coupons or sell Oxtellar XR. To pay less, ask your prescriber or pharmacist whether a generic equivalent exists, check the manufacturer's copay/savings card and patient-assistance program, and compare a pharmacy discount card against your insurance copay. Prices vary by pharmacy, insurance, and location, so always confirm at the counter. This is general reference, not medical or financial advice.
