• The value of antivenom decreases with time following the bite (benefits to local swelling are limited to administration within 24 hours post-bite; however, benefits towards systemic signs, when present, continue even with administration >24 hours post-bite).
• There are no published studies conclusively supporting improved recovery time in small animals.
• This antivenom is unlikely to work for other snake bites and specialist help should be urgently sought for such bites.
