For adults: benzocaine is a topical numbing medicine that can work well but has safety limits. Some governments restrict or ban it for cosmetic use. Most adults tolerate it, but it can sometimes cause skin irritation, allergic reactions, or β rarely β a serious blood problem that reduces oxygen.
Use benzocaine only as the product label or a doctor tells you. Avoid high-strength products (for example, very concentrated formulations) unless prescribed. Donβt put it on large areas of broken skin, near the eyes, inside the nose or mouth, or on mucous membranes unless directed by a clinician. Stop use and get medical help if you have sudden breathing problems, severe dizziness, pale or gray lips/skin, or a fast heartbeat. Keep all benzocaine products out of reach of children and do not use products meant for adults on babies or young children.
Main safety warning: some regulators (Health Canada and the EU Cosmetics Directive) have restricted or banned benzocaine use in cosmetics β that is a signal to be cautious. Watch for skin rash, swelling, or itching (possible allergy). Watch for signs of the rare blood condition methemoglobinemia (very pale or gray skin, shortness of breath, rapid heartbeat, dizziness); this requires immediate medical care. Sources for these warnings include Health Canada and the EU Cosmetics Directive; additional safety notes come from international health reviews (IARC), national toxicology and chemical agencies, and medical literature.
