Itching/Stinging

Itching and stinging are unpleasant skin sensations ranging from mild to intense irritation, potentially caused by allergic reactions, skin irritants, underlying conditions, or medications. Severity and duration vary, and rarely, it indicates a more serious condition.

Itching and stinging sensations are unpleasant skin sensations that can range from mild discomfort to intense irritation. Itching (pruritus) is an urge to scratch, while stinging is a sharp, pricking, or burning sensation. These sensations can occur together or separately and may be localized to a specific area or widespread. Potential causes include allergic reactions, skin irritants, underlying skin conditions (eczema, psoriasis), insect bites, infections (fungal, bacterial), medications (both topical and systemic), and systemic diseases (e.g., liver or kidney disease). The severity and duration can vary depending on the cause and individual sensitivity. Topical applications can induce itching due to vehicle components, preservatives or even the API itself, while systemic drugs may trigger reactions either through direct activation of pruritogenic pathways or through allergic responses. Rarely, itching can be a sign of a more serious underlying condition.
