Blunt-nosed viper bite — how dangerous is it and what should you do?
A suspected gyurza bite can be serious. In Georgia, call 112 now; do not wait for severe symptoms. Move away from the snake, keep movement to a minimum, and do not cut, suck, burn, or tightly tourniquet the bite. Do not try to catch the snake.

How dangerous is a gyurza bite?
The gyurza, called Macrovipera lebetinus in this atlas, is a medically important viper. A bite may deliver little or no venom, or it may cause significant local and systemic envenoming. Serious cases can be life-threatening; neither the wound's appearance nor the atlas risk label predicts an individual's outcome.
Published Macrovipera cases and the 2025 clinical review describe a range of severity. These reports come from other populations and cannot establish the frequency or outcome of bites in Georgia.

What can the venom do?
Macrovipera envenoming can damage tissue around the bite and disturb blood clotting and blood vessels, sometimes causing bleeding. The 2025 review brings together clinical reports and venom research; laboratory clotting results explain a possible mechanism but do not predict what will happen to a person bitten in Georgia.
What symptoms have been reported?
These are possible effects reported in international Macrovipera clinical literature, not a checklist that every patient follows. One published case involved a snake collected in Cyprus; it does not describe a Georgian bite.
- Near the bite: pain, swelling, bruising, blisters, or, in severe cases, tissue damage.
- Beyond the bite: dizziness, weakness, nausea or vomiting, low blood pressure, or abnormal bleeding and clotting tests. Severe cases may involve shock or kidney injury.
Can the bite look mild at first?
Yes. Macrovipera symptoms may evolve after the initial bite, and a small-looking wound or little early pain cannot rule out envenoming. A credible suspected bite needs urgent assessment without waiting for swelling, bleeding, or weakness to appear.
What should you do immediately?
For the full first-aid guidance that applies to any suspected snakebite, read Snakebite in Georgia — what should you do?.
- Move to a safe distance from the snake and call 112 in Georgia.
- Keep the person calm and as still as practical; keep the bitten limb still and remove rings, a watch, or other tight items nearby.
- Arrange prompt medical care and follow the emergency operator's instructions.
What should you avoid?
Do not cut or burn the wound, suck out venom, apply a tight tourniquet, use electric shock, ice, alcohol, or folk remedies. Do not improvise a pressure-immobilization bandage for gyurza: it may worsen injuries where venom causes substantial local tissue damage. Do not catch or kill the snake or delay care to identify it.
When should you call 112?
Call immediately for a credible suspected gyurza bite in Georgia, even before severe symptoms. Georgia's 112 dispatch service sends urgent medical help. Seeing a gyurza nearby without a bite or another emergency is a different situation and does not by itself require an emergency call.
What if a child was bitten?
A child needs especially prompt assessment. WHO notes that children can experience more severe effects from venomous snakebites because of their smaller body mass. This is general snakebite guidance, not a measured pediatric risk for Georgian gyurza bites.
Will antivenom be needed?
Not every bite requires antivenom. In hospital, clinicians assess symptoms, examine the person, and may check blood clotting and other complications. They decide whether an appropriate antivenom is indicated and monitor treatment because serious reactions are possible.
An antivenom tested against venom from another population cannot simply be assumed effective or available in Georgia. We have not verified Georgian hospital stock or a national gyurza treatment protocol. Do not try to obtain or administer antivenom yourself.

What is known about gyurza in Georgia?
The atlas documents the species in eastern Georgia. Its gyurza profile covers identification, distribution, and taxonomy; this article focuses on a suspected bite. The atlas uses Macrovipera lebetinus, while much clinical literature uses M. lebetina for the corresponding taxon.
We found no reliable Georgian clinical series establishing local symptom frequencies, mortality, or current antivenom availability. International cases guide cautious wording but do not replace local evidence.

Should you identify the snake after a bite?
Do not approach or handle it. A photograph already taken from a safe distance can be shared with clinicians if doing so causes no delay. Do not rely on head shape, pupil shape, or a guess to decide whether to call for help. This page is educational and does not replace emergency or clinical advice.
Frequently asked questions
No. A venomous snake can bite without injecting a clinically important amount of venom, but you cannot determine that safely at the scene. A credible suspected bite still needs urgent medical assessment.
