Lamotrigine — Nutrient Depletion & Health Patterns
Also known as: Lamotrigine (Lamictal, Lamictal XR)
Drug Class: Anticonvulsant / Mood stabilizer
Voltage-gated sodium channel blocker used for epilepsy (partial and generalized seizures) and bipolar disorder (bipolar I and II depression maintenance). One of the most prescribed mood stabilizers for bipolar depression — unlike lithium, it primarily prevents depressive rather than manic episodes. Used off-label for treatment-resistant depression and borderline personality disorder. Has a serious rash risk (Stevens-Johnson syndrome) that requires an extremely slow titration protocol to minimize.
Nutrients That Lamotrigine May Deplete
Long-term use of Lamotrigine is associated with lower levels of the following nutrients based on peer-reviewed clinical research. WePattern surfaces these patterns from its clinical Knowledge Graph.
- 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)
Frequently Asked Questions
Does Lamotrigine deplete nutrients?
Yes. Lamotrigine has been associated with depletion of Folic acid, Vitamin B12, Biotin, Vitamin D, CoQ10 based on clinical research. WePattern maps these relationships from peer-reviewed sources.
