Cerastes cerastes venom is reported to be similar in action to Echis venom.
Envenomation usually causes swelling, haemorrhage, necrosis, nausea, vomiting, and haematuria.
A high phospholipase A2 content may cause cardiotoxicity and myotoxicity.
Studies of venom from both C. cerastes and C. vipera list a total of eight venom fractions, the most powerful of which has haemorrhagic activity.
Venom yields vary, with ranges of 19–27 mg to 100 mg of dried venom being reported.
For venom toxicity, Brown (1973) gives LD₅₀ values of 0.4 mg/kg IV and 3.0 mg/kg SC.
An estimated lethal dose for humans is 40–50 mg.
