Lamotrigine, while generally well-tolerated, can cause several side effects. Common ones include dizziness, headache, and nausea. These usually lessen as your body adjusts to the medication. However, more serious, though less frequent, reactions may occur. Always report any concerning symptoms to your doctor immediately.
Skin Reactions
A serious, potentially life-threatening rash called Stevens-Johnson syndrome (SJS) or toxic epidermal necrolysis (TEN) is a rare but possible side effect. This rash often begins as small red or purple spots, possibly with blisters, usually on the face, neck, or torso. Seek immediate medical attention if you experience such a rash. Early detection is vital.
Other Serious Side Effects
Less common but still significant side effects include severe allergic reactions, blood disorders (such as agranulocytosis), and liver problems. Symptoms may vary, so consistent monitoring by your physician is recommended.
Severity and Frequency
| Dizziness | Common | Mild to Moderate |
| Headache | Common | Mild to Moderate |
| Nausea | Common | Mild to Moderate |
| Stevens-Johnson Syndrome/Toxic Epidermal Necrolysis | Rare | Severe, Potentially Life-Threatening |
| Allergic Reaction | Rare | Severe, Potentially Life-Threatening |
Medication Interactions
Lamotrigine can interact with other medications. Always inform your doctor and pharmacist about all medications, supplements, and herbal remedies you are taking to prevent potentially harmful interactions. Accurate and complete information ensures your safety.
Monitoring and Reporting
Regular blood tests may be needed to monitor your blood cell counts and liver function, especially when starting lamotrigine or increasing your dosage. This proactive approach helps identify potential problems early.
