19/ ⚠️ Antivenom Reactions: What to Watch For?
Early allergic reactions: Occur in 3–80%; 5–10% can be severe.
Anaphylaxis: Stop antivenom, give IM adrenaline in the outer thigh. Add IV antihistamines, steroids, bronchodilators as needed. Restart antivenom cautiously if still needed.

Its a diagnostic tool to identify venom type from bite site swabs, blood, or urine. Helps guide antivenom choice, especially where polyvalent antivenom isn't routinely used. Availability and use depend on country and local protocols.
