Lamotrigine — Nutrient Associations & Health Patterns
Also known as: Lamotrigine (Lamictal, Lamictal XR)
Drug Class: Anticonvulsant / Mood stabilizer
Lamotrigine is a Anticonvulsant / Mood stabilizer that may affect nutrient status or medication timing in some contexts. WePattern Pattern Health Intelligence maps evidence-qualified nutrient associations, side effects, and interaction context linked to Lamotrigine.
Reported Nutrient Associations for Lamotrigine
Peer-reviewed research reports relationships involving the following nutrients. WePattern surfaces them as evidence-qualified associations; they do not establish deficiency, causation, or a fixed timeline for an individual.
- Folic acid
- Vitamin B12
- Biotin
- Vitamin D
- CoQ10
Common Side Effects of Lamotrigine
- Serious rash — Stevens-Johnson syndrome (rare but life-threatening — most risk in first 8 weeks if titrated too fast)
- Dizziness and coordination problems (ataxia)
- Headache
- Blurred or double vision (diplopia)
- Nausea
- Insomnia
- Tremor
- Cognitive slowing (less common than other anticonvulsants)
Key Drug Interactions — Lamotrigine
Lamotrigine has 7 documented drug-drug interactions in WePattern's Pattern Health Intelligence database. Key interactions include:
- Valproic acid (doubles lamotrigine levels — rash and toxicity risk — reduce lamotrigine dose by 50%)
- Combined oral contraceptives (reduce lamotrigine levels by 50% — reduces seizure/mood control)
- Carbamazepine (reduces lamotrigine levels by 40%)
- Phenytoin, phenobarbital, primidone (reduce lamotrigine levels)
- Rifampin (reduces lamotrigine levels)
- Other mood stabilizers (additive neurological effects)
