Oxcarbazepine

Seizures and epilepsy

Also known as Trileptal

Oxcarbazepine calms the runaway electrical signals that cause seizures. It's closely related to carbamazepine but tends to have fewer drug interactions. One thing to watch: it can lower the sodium in your blood, especially in the first few months — that shows up as headache, nausea, confusion, or feeling foggy, and it's worth a call to your doctor.

How to take it

When

Usually twice a day, at the same times each day.

Food

With or without food.

Avoid

Alcohol — it adds to the drowsiness. Don't drive until you know how this affects you; seizure driving laws also apply.

Good to know

It can make hormonal birth control less reliable — ask your doctor about backup options.

Missed a dose?

Take it when you remember, unless it's almost time for the next dose — then skip it. Missed doses can trigger seizures, so ask your doctor ahead of time what to do. Never take a double dose.
