Serum sickness (type III hypersensitivity reaction) up to 12 days after antitoxin admin, symptoms include: Urticaria, fever, pruritus, malaise, skin rash and arthralgia. Accelerated serum sickness (occurring <7 days after immunisation) may occur in individuals with previous admin of equine serum.


Diptherias antitoxin is used, often concurrently with an antibiotic, for passive immunisation against suspected diphtheria infection. It contains specific globulins which negate the local and systemic effects of toxins produced by Corynebacterium diptheriae.

ADS Precaution

History of asthma. Test doses should be administered before immunisation to eliminate hypersensitivity. Adrenaline inj and resuscitation facilities should be available after all immunisation. Not used for diphtheria prophylaxis because of hypersensitivity risk. A negative sensitivity test dose so not completely exclude systemic sensitivity. If hypersensitivity occurs during or immediately after desensitisation procedure, a tourniquet should be applied and adrenaline administered next to the site of inj.
