Promethazine, trade name Phenergan, has a wide variety of uses. This drug is prescribed for reasons also applicable to dogs. No wonder pet parents are asking about it!
Phenergan works as a sedative, antihistamine and antiemetic (motion sickness treatment). This medication is sometimes provided to dogs and without incident.
We do not encourage owners to give leftover prescription drugs to their dogs. That said, short-term use of Phenergan is often successful when it is dosed properly.
Can I Give My Dog Phenergan? Answer: Yes
The biggest concerns are misuse, inappropriate dosing and interactions with other drugs.
Phenergan is generally safe for dogs when appropriately used. Without a diagnosis, however, misuse is a concern. Your dog may have a problem that can’t be helped with Phenergan. In such a case, Promethazine could make matters worse. Pharmaceuticals for pets should always be a last resort.
Fido’s problems should be addressed at the root. Phenergan isn’t a long-term fix. Try a much safer alternative if you’re simply trying to calm your dog.
Multiple Phenergan Uses
Promethazine is favored because it’s a treatment for common canine problems. Dogs with allergies or hypersensitivity disorders can be helped with Phenergan. This Antihistamine has a good track record.
The drug is also useful for motion sickness, or if your dog needs to be calmed. That said, there could be better and more appropriate options for your pet’s particular situation.

Harmful Drug Interactions
If your dog is on other medications, in addition to Phenergan, then a vet’s help becomes even more important. Promethazine may negatively interact with drugs such as Hydroxyzine.
Bad interaction possibilities are compounded with canines. Dogs are more susceptible to harm since their internal organs are smaller. Make no mistake about it, Phenergan can be dangerous.
Safe Dosing for Pet Dogs
This is for reference only and checking with a vet is a must. 1mg for every 2 pounds, taken twice daily is a conservative Phenergan dose for most dogs.
Sometimes a higher amount is needed, but the risks increase. Dosing should also depend on your treatment objective.
Most owners crush up tablets and mix the contents in with regular dog food.
If you lack knowledge, or aren’t confident, do not provide any amount of Phenergan. This also goes for other antihistamines.
Phenergan’s Side Effects
Every drug comes with the potential for scary side effects and Phenergan is no different. Your dog may suffer from a central nervous system depression which can be quite serious.
It’s essential to watch over your pet dog whenever they’re given Phenergan. Dry mouth is common, but sometimes the sedative effects can be overwhelming for animals.
Ask your vet about the possibility of Polaramine instead of Promethazine. Better yet, try a natural calming alternative that’s designed for pets.
Conclusion on Phenergan
Phenergan does have risks and sometimes side effects. It’s a sedative for high-strung pets. This prescription antiemetic is often provided before road trips. Phenergan is also a antihistamine for dogs with allergies. Proper dosing and interacts are concerns. Involve a vet before administering Phenergan to your dog.
