What should you know about Lamictal rash?

A rash may look like flat pink or red spots, raised bumps, hives or patches, and appearance alone cannot show whether it is mild. A drug rash is one possibility, while atopic dermatitis, contact dermatitis, heat rash, intertrigo, psoriasis, ringworm or scabies can produce similar-looking changes. Timing, distribution, itch, pain and other symptoms help a clinician assess the cause.

The risk of a serious reaction is the reason a new rash should not be ignored. Take note of when Lamictal was started or adjusted, and list every prescription, supplement and skin product you use.

Contact the prescriber or an urgent medical service as soon as possible for advice. Do not take an extra dose, restart a missed course or stop treatment abruptly without instructions from a clinician who knows why you take it, unless emergency services tell you otherwise. Photograph the rash in clear light and avoid applying unfamiliar creams before assessment.

Use gentle washing, plain moisturiser and loose clothing if the skin is comfortable. Avoid heat and scratching, and keep the medicine packaging available for the consultation.

Call emergency services for blistering, peeling or painful skin; sores in the mouth, eyes or genitals; fever with a spreading rash; facial swelling; breathing difficulty; severe weakness; or faintness. Do not wait for the rash to become extensive when these signs occur.

Ask whether you should take the next dose, how the rash will be examined, which warning signs to monitor, and how any replacement medicine would be started safely.
