What Is Temaril-P®?
Temaril-P® is an FDA-approved medication prescribed by veterinarians for itching and coughing in dogs, especially if triggered by environmental allergies and inflammation. Temaril-P® is a combination of 2 medications—the antihistamine trimeprazine and the corticosteroid prednisolone. Temaril-P® does not cure allergies and inflammation, but it can help suppress related symptoms.
Although uncommon, Temaril-P® is sometimes prescribed for the treatment of itching in cats. The use of Temaril-P® in cats is considered off-label. The term off- or extra-label use means that a medication can be used in a way or in a particular species that is not specified on the medication label. Veterinarians can legally prescribe medications for off-label use in certain circumstances. Your veterinarian will determine whether this medication is right for your pet.
In certain circumstances, your vet may recommend a compounded formulation of Temaril-P®. Compounded medications are prescribed if there’s a specific reason your pet’s health can’t be managed by an FDA-approved drug, such as if your pet has trouble taking pills in capsule form, the dosage strength is not commercially available, or the pet is allergic to an ingredient in the FDA-approved medication. Compounded medications are not FDA-approved. They are created by a veterinarian or a licensed pharmacist on an individual basis to best suit a patient’s particular needs.

How Temaril-P® Works
Temaril-P® is a combination of trimeprazine, an antihistamine, and prednisolone, a corticosteroid. Trimeprazine blocks the effects of histamine, a chemical messenger produced with environmental allergies and inflammation, which occurs with an overreactive immune system. As an antihistamine, trimeprazine can help suppress coughing and itching.
As a corticosteroid, prednisolone blocks harmful effects of inflammation through multiple complex pathways. Treatment with a trimeprazine/prednisolone combination may be more effective for itching than treatment with prednisolone alone. This reduces the dose of prednisolone needed to help control your pet’s symptoms, which can help your pet experience fewer medication-related side effects.
Follow the directions on the drug label or as provided by your veterinarian. Always provide your pet with plenty of water when they are taking Temaril-P®.
Temaril-P® can be given with or without food, but giving it with food can decrease the risk of digestive upset.
If your veterinarian recommends that you discontinue this medication for any reason, it is best to wean your pet off slowly, under a veterinarian's supervision, especially if they have been taking it long term.
Missed a Dose?
Speak with your veterinarian about what to do if you forget to give a dose of Temaril-P®. Generally, they may instruct you to give it when you remember, or, if it is almost time for your pet’s next dose, to skip the missed dose and resume your normal dosing schedule. Do not give extra or double doses

Temaril-P® for Dogs and Cats FAQs
