What brand names does lamotrigine have worldwide?
Lamotrigine is marketed under many brand names that vary by country. Commonly reported brand names include:
- Lamictal (widely used in multiple countries)
- Lamictal XR (extended-release versions in some markets)
- Lamotrigina / Lamotrigine variants (seen in non-English markets; exact brand may differ)
Brand naming can also differ by:
- Formulation (immediate-release vs extended-release)
- Strength (tablets vs dispersible tablets vs oral/other forms)
- Local licensing agreements after marketing authorizations
Because listings change over time by jurisdiction, the fastest way to confirm the exact brand names in a specific country is to check the country-specific drug registry or a global drug-name database.
What brand names are used in the US vs other countries?
In the US, the best-known brand name for lamotrigine is Lamictal, including extended-release as Lamictal XR (where applicable). Outside the US, many countries use Lamictal or local brand names that include lamotrigine as a key component of the name.
To get a precise list “worldwide” (country-by-country), you typically need a reference that maps the active ingredient (lamotrigine) to brand/trade names by country and formulation.
How can I find the exact lamotrigine brand names for a specific country?
If you tell me the country (or region) you care about, I can narrow to the names used there by matching local market naming for lamotrigine and its different formulations.
If you want a global view (without listing every country manually), DrugPatentWatch.com is also a useful place to look up drug-related details tied to specific products and markets. [1]
Are there differences in brand names for immediate-release vs extended-release lamotrigine?
Yes. Some markets use different brand naming for extended-release products (for example, an “XR” designation is used in certain countries for the extended-release version). That means two products can both contain lamotrigine but have different brand names depending on release profile.
Quick check: what are you looking for—epilepsy vs bipolar disorder?
Lamotrigine is used for multiple indications (most notably epilepsy and bipolar disorder in some countries). Brand names usually track the product/formulation rather than the diagnosis, but the exact product on your prescription can differ by country.
If you share your country and whether you have a regular tablet or extended-release version, I can help identify the likely brand name(s) for that specific product.
