Benadryl, a common over-the-counter antihistamine for humans, is often used to treat allergic reactions in dogs. While it can be effective in relieving symptoms like itching, sneezing, and hives, it is also known to cause drowsiness in both humans and animals. So, the question arises, does Benadryl make a dog sleepy?
This article delves into the effects of Benadryl on dogs, specifically exploring its impact on sleepiness and other potential side effects. We will discuss the reasons behind drowsiness, the dosage considerations, and when to seek veterinary advice.
Why Does Benadryl Make Dogs Sleepy?
Benadryl, containing diphenhydramine, is an antihistamine that works by blocking the effects of histamine, a chemical released by the body during allergic reactions. While it effectively relieves allergy symptoms, diphenhydramine also has sedative properties. These properties are the reason behind drowsiness as a common side effect in dogs.
How Benadryl Affects the Nervous System
Diphenhydramine affects the central nervous system by blocking certain receptors in the brain, including the histamine H1 receptor. This blockage leads to a reduction in the activity of the central nervous system, resulting in drowsiness, relaxation, and decreased alertness.
Benadryl Dosage for Dogs: A Critical Factor
Dosage is a crucial factor when administering Benadryl to dogs. Giving the wrong dose can lead to serious side effects, including excessive drowsiness, lethargy, and even toxicity.
Factors Influencing Dosage
Several factors influence the appropriate Benadryl dosage for a dog, including:
- Weight: The dog’s weight is a primary consideration.
- Severity of Symptoms: Dosage may be adjusted depending on the severity of the allergic reaction.
- Individual Sensitivity: Some dogs may be more sensitive to diphenhydramine than others.
Consulting Your Veterinarian
It’s vital to consult your veterinarian before administering Benadryl to your dog. They can determine the appropriate dosage based on your dog’s individual needs and monitor them for any adverse reactions.
When Does Drowsiness Become a Concern?
While drowsiness is a common side effect of Benadryl, it usually subsides within a few hours. However, if your dog exhibits prolonged or excessive sleepiness, lethargy, or other concerning symptoms, it’s essential to seek immediate veterinary attention.
Signs of Overdosage
Signs of Benadryl overdosage in dogs include:
- Excessive sleepiness
- Dizziness
- Loss of coordination
- Rapid heartbeat
- Dilated pupils
- Vomiting
- Seizures
If you suspect your dog has overdosed on Benadryl, contact your veterinarian or the ASPCA Animal Poison Control Center immediately.

Apart from drowsiness, Benadryl can also cause other side effects in dogs, though these are less common.
Common Side Effects

Serious Side Effects
In rare cases, Benadryl can cause more severe reactions, including:

Conclusion

While it usually subsides quickly, it’s vital to be aware of the potential for prolonged sleepiness and other adverse reactions.
