If your canine companion struggles with severe fear of thunderstorms or experiences motion sickness during travel, your veterinarian might recommend a mild sedative. One commonly prescribed option is acepromazine, an Ace Medication For Dogs known for its sedative properties. It’s crucial to remember that acepromazine is strictly for veterinary use and not intended for humans. Accidental ingestion by a child or adult warrants an immediate call to Poison Control (1-800-222-1222), as it can cause drowsiness and slowed breathing. When administered at the correct dosage, acepromazine can be an effective and economical choice for canine sedation. This article will delve into the proper applications of acepromazine for dogs, its common side effects, and potential interactions with other medications, providing essential information for responsible pet owners.
What is Acepromazine and Why is it Prescribed for Dogs?
Acepromazine serves as a long-acting, mild sedative in veterinary medicine. Dr. Amy Attas, VMD, of City Pets in New York, highlights its key benefit: “You get prolonged sedation with a single dose.” Beyond its sedative effects, this ace medication for dogs also possesses anti-nausea properties, making it a viable option for pets prone to motion sickness during travel. Its affordability and availability in both oral and injectable forms contribute to its widespread use. Oral medication comes in various strengths, allowing for dosage adjustments based on a dog’s weight. Alternatively, veterinarians can administer the drug intravenously or subcutaneously (under the skin).
The oral form of acepromazine can be less predictable than the injectable version due to varying absorption rates. This means two dogs of the same weight might require different oral doses to achieve a similar level of sedation. Additionally, the tablets are highly light-sensitive and should be stored in a dark bottle, away from direct sunlight.
However, many veterinarians are increasingly opting for newer alternatives like trazodone, which offer similar or superior anti-anxiety effects with fewer side effects. A significant advantage of these newer sedatives is their reversibility. If a higher dose than necessary is given, a reversal medication can be administered to counteract the sedation. In contrast, removing acepromazine from a dog’s system solely relies on time and supportive care, such as fluid administration. This reversibility makes newer drugs a safer choice in many situations.
If you plan to use this ace medication for dogs for mild sedation or travel, it’s highly recommended to conduct a test run. Before embarking on a car or airplane trip, administer the veterinarian-recommended dose at home to assess its effectiveness. Observe if it provides the desired level and duration of sedation for your dog. If the results are not satisfactory, consult your veterinarian before making any dosage changes.

Potential Side Effects and Drug Interactions of Ace Medication for Dogs
While effective, acepromazine can cause several side effects and interact negatively with certain medications and chemicals. Discuss these potential issues with your veterinarian before administering the drug.
Prolonged Sedation
Acepromazine is not ideal for short-term sedation needs. Its effects can last for six to seven hours, particularly in older dogs. This ace medication for dogs should also be avoided in puppies and dogs with liver disease.
Third Eyelid Effect
Dogs possess a third eyelid, or nictitating membrane, which usually remains unseen. A common side effect of acepromazine is the protrusion of this third eyelid, which can be alarming to owners as it might cover up to two-thirds of the eye. It’s important to distinguish this from “cherry eye,” where the gland beneath the third eyelid becomes swollen and everted. With acepromazine, the gland appears tan or pink, not red and inflamed. The third eyelid will recede once the drug’s effects wear off.

Drop in Blood Pressure
A significant concern with acepromazine is its potential to decrease a dog’s blood pressure. This risk is amplified if your dog already suffers from low blood pressure due to another condition. Caution is advised when combining acepromazine with narcotics for pain medication for hip dysplasia in dogs or other pain relief, as this combination can further exacerbate blood pressure drops. It’s generally best to avoid giving acepromazine at home if your dog is on narcotics. Dehydration is another risk factor for low blood pressure. Therefore, ensuring your dog is healthy and well-hydrated is crucial to prevent alarming blood pressure drops when administering this medication. Dogs with conditions like diabetes, Addison’s disease, and kidney disease are prone to dehydration, making acepromazine a less suitable choice for them. If your dog is dealing with chronic joint issues, discussing options like new arthritis medication for dogs or best medication for dogs with hip dysplasia with your vet is important for comprehensive care.
Interactions with Flea Treatments
Certain flea collars and environmental flea treatments contain organophosphate insecticides, chemicals used to control insects. These chemicals interact negatively with acepromazine, meaning they should not be used concurrently. Always check the ingredients of any homemade flea and tick treatment for dogs or commercial products to ensure there are no harmful interactions. Similarly, when considering a natural flea treatment for dogs that works, always consult your veterinarian about potential interactions with any prescribed medications.
Interactions with Gastrointestinal Medications
Acepromazine can interact negatively with medications used to treat constipation or other gastrointestinal disorders. This includes drugs like cisapride (which aids GI tract movement), metronidazole (used for diarrhea), and metoclopramide (which can cause neurological symptoms when combined with acepromazine). Additionally, combining acepromazine with ondansetron (Zofran), an anti-nausea medication, should be avoided. Antacids can also increase the sedative effects of acepromazine, making their concurrent use undesirable.
When to Avoid Using Ace Medication for Dogs
Acepromazine does not possess any analgesic (pain-relieving) properties. If your dog requires pain management, your veterinarian might administer an opioid alongside acepromazine. However, this combination necessitates careful monitoring to prevent a drop in blood pressure.
Furthermore, acepromazine is often a poor choice for dogs suffering from anxiety or phobias, such as a fear of thunderstorms. Despite being a sedative, it lacks anti-anxiety properties. Dogs sedated with acepromazine may still experience anxiety, and their loss of mobility can intensify their fear, as they cannot move away from the source of their distress.
Certain breeds have difficulty metabolizing this medication, making them more sensitive to its effects. These include sighthounds such as Greyhounds, Whippets, Salukis, and Afghan Hounds. There have also been reports in the UK of some Boxer lines exhibiting an exaggerated response to acepromazine, though this appears to be rare. Additionally, some Collie breeds possess the Multidrug Resistance 1 (MDR1) gene mutation, which impacts how they metabolize acepromazine. If this is a concern, your vet can test for this gene mutation. Generally, it’s best to avoid using ace medication for dogs in Collie breeds.

In conclusion, while ace medication for dogs (acepromazine) can be a useful tool for sedation and anti-nausea, particularly for specific situations like motion sickness, it’s essential to understand its limitations and potential risks. Always consult your veterinarian to determine if acepromazine is the right choice for your dog, considering their health status, breed, and any other medications they may be taking. Remember to conduct a test run for behavioral uses and be vigilant for side effects. Prioritizing your dog’s safety and comfort through informed decisions is key to their well-being.
