Epinephrine in Numbing Cream: Benefits, Risks, and a Real Medical Case

A balanced look at why some tattoo numbing creams contain epinephrine, and what the medical literature warns about.

Epinephrine (adrenaline) is added to some numbing creams to constrict blood vessels. The upside: less bleeding and longer-lasting numbness. The downside: it must be used carefully.

What the research warns

A 2023 medical case report describes a 33-year-old woman who developed severe lactic acidosis and a heart-stress pattern (NSTEMI) after repeated application of a lidocaine + epinephrine topical anesthetic before a tattoo [1]. The authors stress this is rare but urge awareness of systemic epinephrine toxicity.

Epinephrine content by product (%)

In our range, TKTX Cream, TKTX Gel and Perfso contain epinephrine; MANTUOLA, J-PRO, Mithra and J-CAIN do not. Nonepi products are a popular choice for those who want to avoid vasoconstrictors.

Never over-apply or re-cover epinephrine-containing cream beyond the label. If you feel racing heartbeat, chest tightness or anxiety after use, seek medical help.
