Overview of Piriton for Dogs
Piriton, containing chlorpheniramine maleate or chlorphenamine, is an over-the-counter antihistamine used to relieve allergy symptoms in both humans and dogs. It should only be administered under veterinary guidance, with dosage depending on the dog's weight and condition. While generally safe, it can cause side effects like drowsiness and should be used cautiously in dogs with certain health conditions or those on other medications.
This is a human medicine that is prescribed by a veterinary professional under the prescribing cascade. Human-licensed medication could be prescribed under step (c)(i) (in Great Britain) or (b)(i) (in Northern Ireland) of the prescribing cascade, however, the justification in this case would also need to account for why a veterinary medicine (authorised for that species and condition, or for another species or condition) could not be used.
In exceptional emergency circumstances, a veterinarian may assess the need to relieve your furbabies discomfort until a home visit can be arranged or the pet can be brought to the clinic. It may be suggested that the pet parent may use a human medicine they already possess, such as antihistamine tablets. However, this does not imply that pet parents should be advised to seek human medicine for their pets from a pharmacy. https://www.rcvs.org.uk/faqs/can-i-advise-that-a-client-use-over-the-counter-human-medicines/
Chlorpheniramine maleate, commonly known as Piriton (note this is not the same as Piritize), is a first-generation antihistamine drug used primarily in dogs and cats to control itching or as a mild sedative. It works by blocking the action of histamine, particularly its effect on H1 receptors, which reduces or prevents swelling and itchiness without affecting heart rate or stomach acid secretions.
