Can Lamictal (lamotrigine) cause a rash?
Yes. Lamictal (lamotrigine) can cause a rash, and some rashes can be serious. A rash is a known potential side effect of lamotrigine, and it can occur early in treatment, especially when doses are increased too quickly. [1]
What kinds of rashes can happen, and when do they show up?
Rashes related to lamotrigine can range from mild to life-threatening. The most concerning are severe skin reactions such as SJS/TEN and drug reaction with eosinophilia and systemic symptoms (DRESS). These reactions typically occur within the first weeks of starting Lamictal or after dose escalation. [1]
What should you do if you notice a rash while taking Lamictal?
Seek urgent medical advice if you develop a rash while on Lamictal, particularly if it comes with symptoms like fever, facial swelling, blistering, skin peeling, sores in the mouth/eyes, or trouble breathing. Severe reactions can progress quickly, so clinicians generally recommend stopping and getting evaluated right away if a concerning rash appears. [1]
Who is at higher risk of a serious rash from Lamictal?
Risk is higher with faster dose increases and with higher starting doses. Clinicians also consider other factors that can affect exposure (for example, drug interactions that change lamotrigine levels) when choosing a dosing schedule. [1]
Does Lamictal rash happen more with certain dosing or co-medications?
Rash risk is tied to how Lamictal is titrated (increased). Interacting medications can raise lamotrigine levels and increase the chance of skin reactions if dosing isn’t adjusted accordingly. [1]
