What should you know about rash from Vyvanse?

Note whether the rash is flat, raised, hive-like, scaly, or painful, and whether it began after starting Vyvanse or changing its dose. The active medicine, an inactive ingredient, or another exposure may be involved. A drug eruption is possible, but Contact Dermatitis, Atopic Dermatitis, Heat Rash, and other conditions can resemble it. A photo and a dated medicine list help a clinician compare the pattern with the timeline.

Call the prescriber or pharmacist promptly and describe the rash before changing the treatment plan. Avoid sharing Vyvanse or replacing it with another stimulant. Until advised, use gentle unscented cleanser, loose clothing, and cool compresses; avoid applying a new steroid, antibiotic, or herbal product unless a professional recommends it. Keep the medicine container and note every dose, supplement, and recent product.

Seek emergency help for breathing difficulty, throat or tongue swelling, collapse, or widespread hives. Go urgently for blistering, skin peeling, purple or target-like marks, fever, facial swelling, or sores involving the mouth, eyes, or genitals. Even without these signs, a rash that is spreading or becoming painful should be assessed promptly.

Ask if Vyvanse should be held, whether another ingredient could explain the reaction, and how attention symptoms should be managed meanwhile. Ask what alternative treatment is suitable and how to document this reaction for future prescriptions.
