Overview: Diphenhydramine, commonly known by its brand name Benadryl, is an antihistamine often used to treat allergies in both humans and dogs. However, giving your dog diphenhydramine should always be done with caution and under the guidance of a veterinarian. This article will discuss the potential benefits, risks, and proper dosage of diphenhydramine for dogs.
Diphenhydramine: A Common Antihistamine for Dogs
Diphenhydramine is a safe and effective medication for treating mild allergies in dogs, but it’s crucial to understand the proper dosage and potential risks.
Benefits of Diphenhydramine for Dogs
Diphenhydramine, a first-generation antihistamine, blocks histamine receptors in the body. Histamine is a chemical released by the body in response to allergens, causing symptoms like itching, sneezing, and swelling. By blocking these receptors, diphenhydramine helps reduce these symptoms.
Here are some common situations where diphenhydramine might be helpful for dogs:
- Allergic reactions: Diphenhydramine can relieve symptoms like itching, swelling, and hives associated with allergic reactions to things like pollen, insect bites, or certain foods.
- Motion sickness: Diphenhydramine can be used to reduce nausea and vomiting associated with motion sickness in dogs.
- Anxiety: In some cases, diphenhydramine may be used to help reduce anxiety in dogs, especially when used in conjunction with other calming methods.
Risks and Side Effects of Diphenhydramine for Dogs
While generally safe, diphenhydramine can cause side effects in some dogs. The most common side effects include:
- Drowsiness: Diphenhydramine is known to cause drowsiness in dogs, so it’s important to avoid activities requiring alertness after administering the medication.
- Dry mouth: Diphenhydramine can cause dry mouth, which may lead to increased thirst and panting.
- Gastrointestinal upset: Some dogs may experience vomiting, diarrhea, or loss of appetite after taking diphenhydramine.
- Urinary retention: In rare cases, diphenhydramine can cause urinary retention in dogs.
Important Note: Diphenhydramine should never be given to pregnant or nursing dogs without consulting a veterinarian. It is also important to avoid giving diphenhydramine to dogs with certain pre-existing conditions such as glaucoma, heart problems, or liver disease.
Proper Dosage of Diphenhydramine for Dogs
The proper dosage of diphenhydramine for dogs depends on their weight and the severity of their condition. Always consult your veterinarian for the appropriate dosage for your dog. They will consider your dog’s individual needs and medical history to determine the safest and most effective dosage.
General Guideline: The recommended dosage of diphenhydramine for dogs is typically between 1-2mg per pound of body weight, administered orally every 8-12 hours. However, this is just a general guideline and the actual dosage may vary depending on the dog’s individual needs.
Overdosing on Diphenhydramine:
Overdosing on diphenhydramine can be dangerous for dogs. Symptoms of diphenhydramine overdose in dogs may include:
- Excessive drowsiness
- Weakness
- Coma
- Seizures
- Dilated pupils
- Increased heart rate
- Tremors
If you suspect your dog has overdosed on diphenhydramine, seek immediate veterinary attention.
When to Consult a Veterinarian
While diphenhydramine can be a helpful medication for dogs, it’s essential to remember that it’s not a substitute for proper veterinary care. Always consult a veterinarian before giving your dog any medication, including diphenhydramine.
Here are some instances when you should seek immediate veterinary attention:
- If your dog is exhibiting severe allergic reactions like difficulty breathing, facial swelling, or hives.
- If your dog is vomiting or having diarrhea.

Conclusion: Diphenhydramine can be a helpful medication for managing mild allergies in dogs, but it should always be used with caution and under the guidance of a veterinarian. Understanding the proper dosage, potential risks, and side effects of diphenhydramine is crucial for ensuring your dog’s safety and well-being.
