Antihistamines (Pheniramine maleate, Chlorpheniramine maleate, Promethazine)

29.1.2 Antihistamines (Pheniramine maleate, Chlorpheniramine maleate, Promethazine)

These drugs are useful in some cases of poisoning, particularly if part of the body is swollen. It is also useful for insect bites and stings. Antihistamines are only useful if given to the animal very soon after it becomes ill. If the animal was bitten or stung several days ago, this medicine will probably be of no use. See allergies, Chapter 5, page 84.

Follow the label for dosage and instructions.

If one injection does no good, there is no point in repeating it. If the first injection helps, then injections should be given twice a day until the animal is better.
