Grandmother has been taking lamotrigine 25 mg at night for 1 week. i noticed a red rash on her belly / navel about the size of my palm. could this be the dangerous rash? is it safe to stop the med?

Lamictal rash: Yes rash with Lamictal is serious and must be seen and if only taking 25 mg for a week can stop it, but needs to see her doctor for different treatment.

Use caution: The Lamotrigine rash if painful or itchy, can lead to stevens-johnson syndrome or epidermal necrosis, and is not something to decide here online. The presentation of the rash requires immediate notification to your doctor now, and there needs to be a joint decision today. Maybe of limited importance, but may be a significant event. Do not delay.
