Extended-Release Lamotrigine Dosage

Your dosage of extended-release lamotrigine will depend on several factors, such as how you respond to the medicine and whether you are taking other drugs. Typically, this medication is taken once a day. To ensure your safety, your healthcare provider will start you at a lower dose and gradually increase the amount until the ideal dosing is reached.

An Introduction to Dosing With Extended-Release Lamotrigine

The dose of extended-release lamotrigine (Lamictal® XR™) your healthcare provider recommends will vary, depending on a number of factors, including:
 
  • How you respond to extended-release lamotrigine
  • Other medications you may be taking
  • Other medical conditions you may have.
     
As is always the case, do not adjust your dosage unless your healthcare provider specifically tells you to do so.
 

Recommended Dosage for Seizures

Dosing for extended-release lamotrigine is complicated. Not only will the recommended dose change depending on other medications you are taking or other medical conditions you have, but extended-release lamotrigine must be started at a low dose and increased slowly (for up to eight weeks), which can be confusing for people.
 
Make sure your healthcare provider knows about every medication you are taking, as well as your other medical conditions, especially kidney or liver problems.
 
Increasing your extended-release lamotrigine dosage faster than recommended can increase your risk of side effects, especially a life-threatening rash (see Lamictal Rash). Be sure you understand your healthcare provider's instructions thoroughly and follow them closely.
 
If you have stopped taking extended-release lamotrigine for a while (even for just a few days), talk to your healthcare provider, as you may need to start at a lower amount and slowly increase your dose again.
