From Marine Venom to Medical Innovation: A New Pain Relief Cream for Stings — What Travelers Need to Know

Scientific innovation sometimes begins in unexpected places — including the spines of an invasive fish.

A Montreal-based pain researcher, Reza Sharif-Naeini, director of the McGill University Pain Research Centre, has developed a topical cream designed to neutralize severe pain caused by venomous marine stings.

For travelers, divers, fishermen, and beachgoers, this development is particularly relevant.

The Origin: Lionfish Envenomation

Lionfish, now present in many warm coastal waters, possess dorsal spines that inject a potent venom capable of causing intense, immediate pain. Historically, the primary first-aid intervention has been immersion of the affected limb in hot (but not scalding) water to denature venom proteins — a measure that is not always practical during travel or at sea.

After several years of laboratory research identifying the specific nociceptive receptors activated by lionfish venom, Sharif-Naeini’s team formulated a topical cream using a molecule derived from rhubarb to interrupt the pain signaling pathway.

Why This Matters for Travelers

Marine and insect stings are not rare travel events:

• Lionfish stings: ~10,000 annually
• Jellyfish stings: ~150 million annually worldwide
• Bee and wasp stings: common during outdoor travel
• Mosquito bites: frequent in tropical and subtropical regions

Divers reported that the cream appeared effective not only for lionfish stings but also for jellyfish envenomation. Early data suggest potential utility for other venomous or insect-related stings as well.

For adventure travelers, scuba divers, cruise passengers, and families vacationing in coastal regions, rapid pain control can significantly impact safety, comfort, and the ability to continue travel plans.

Venom Research: A Growing Therapeutic Field

Venom-derived medicine is an expanding field of pharmacology. A well-known example is Ozempic, developed from research into compounds found in the saliva of the Gila monster.

Scientists estimate that less than 10% of global venom compounds have been characterized. These biologically active molecules represent a substantial and largely untapped source of potential therapeutics.

Regulatory Status — Critical for Canadian Travelers

The cream developed by the company Stingmaster is:

• Approved by the U.S. Food and Drug Administration (FDA)
• Not yet approved by Health Canada

For Canadian travelers, this distinction is important. A product approved in the United States cannot be routinely dispensed or marketed in Canada until Health Canada authorization is granted.

At Destinations Travel Clinic, we only recommend and dispense therapies that meet Canadian regulatory standards.

What Travelers Should Do Now

Until this product becomes available in Canada, prevention and evidence-based first aid remain essential.

What to do if you’re stung by a jellyfish:

• Rinse with vinegar (not fresh water)
• Carefully remove tentacles
• Seek medical evaluation for severe pain or systemic symptoms

What to do if you’re stung by a bee or a wasp:

• Remove stinger promptly
• Apply cold compress
• Monitor for allergic reaction

Signs that you require urgent care after a sting:

• Difficulty breathing
• Swelling of face or throat
• Widespread hives
• Dizziness or fainting

Travelers with known severe allergies should carry epinephrine auto-injectors and ensure they are up to date before departure.

Why This Matters at Destinations Travel Clinic

At Destinations Travel Clinic, our team primarily consists of physicians and nurses specializing in travel health medicine, supported by pharmacists trained in travel health.
