When you take lamotrigine, a prescription medication used to control seizures and stabilize mood in bipolar disorder. Also known as Lamictal, it helps many people manage their condition—but not without risks. While it works well for epilepsy and bipolar disorder, it’s not harmless. Some side effects are mild, like dizziness or headaches. Others, like a serious skin rash, can be life-threatening and need immediate medical attention.
One of the biggest concerns with lamotrigine, a mood stabilizer and anticonvulsant is the risk of a rare but dangerous skin reaction called Stevens-Johnson syndrome. This isn’t common, but it’s more likely in kids, people who start too high a dose, or those taking it with valproic acid. If you notice a red, blistering rash—especially around the mouth, eyes, or genitals—stop taking it and get help right away. You should also watch for fever, swollen glands, or flu-like symptoms. These can signal a deeper problem. Another common issue is dizziness or trouble balancing, which often fades as your body adjusts. Fatigue, nausea, and trouble sleeping show up in many users too. Unlike some other seizure meds, lamotrigine doesn’t usually cause weight gain or major liver damage, which is why doctors often pick it over alternatives.
It’s not just about the physical side effects. People on lamotrigine, a medication that affects brain chemicals like glutamate and GABA, sometimes report brain fog or trouble concentrating. That can be frustrating if you’re trying to work, study, or care for family. And while it’s not addictive, stopping suddenly can trigger seizures or mood crashes—so never quit cold turkey. Your doctor will slowly raise your dose to cut down on risks. Most people tolerate it fine, but if you’ve had a bad reaction to other anticonvulsants, you might be more sensitive. It’s also important to know that lamotrigine can interact with birth control pills, making them less effective, and with certain antidepressants, which can change how it works in your body.
