Common skin effects of Semaglutide
According to the prescribing information for Semaglutide, common skin reactions include mild rash, dryness, mild itching, transient flushing and (for some agents) photosensitivity that makes the skin more sensitive to UV. Semaglutide binds and activates the GLP-1 receptor, a G-protein coupled receptor expressed in pancreatic beta and alpha cells, the central nervous system and the gastrointestinal tract. Most are mild, appear in the first weeks and resolve without intervention or with simple measures (moisturiser, sunscreen).
Serious skin reactions
Severe skin reactions — Stevens-Johnson syndrome, toxic epidermal necrolysis, drug-induced hypersensitivity syndrome — are rare but life-threatening. Warning signs are a rash with fever, mucosal involvement (mouth, eyes), skin peeling, or rapidly spreading rash. Any of these on Semaglutide at 0.25mg, 0.5mg, 1mg, 2mg, 1.7mg, 2.4mg is a medical emergency and reason to stop the medication and seek immediate care.
