What brand names does lamotrigine come in?
Lamotrigine is marketed under a number of brand names in different countries. Common brand-name versions you may see include:
- Lamictal
- Lamictal XR (extended-release)
- Lamotrigine (brand products vary by country)
Why do brand names differ by country?
Brand availability depends on local approvals and how manufacturers label the same active ingredient (lamotrigine). In many markets, the generic name (lamotrigine) is used while brand-name products (like Lamictal and Lamictal XR) may be available only where specific manufacturers hold marketing rights.
How to check you’re getting the right lamotrigine product
If you’re trying to identify the exact product, check the prescription label or package for:
- The active ingredient: lamotrigine
- The formulation: immediate-release vs extended-release (often noted as XR)
- Strength (e.g., tablets in mg)
Are there any notable product differences (IR vs XR)?
Yes. Immediate-release lamotrigine and extended-release (commonly sold as “XR”) are designed to release drug differently over time. That can affect dosing schedules and how quickly drug levels rise, so switching between IR and XR should only be done if the prescriber approves.
