Will My Dog Fall Asleep With Benadryl?: Understanding the Sedative Effects
Benadryl can induce drowsiness in dogs, but it’s not a guaranteed sedative. The response varies depending on the dog’s size, breed, individual sensitivity, and the underlying reason for administration.
Understanding Benadryl and Its Effects on Dogs
Benadryl, also known generically as diphenhydramine, is an antihistamine commonly used in both humans and dogs. It works by blocking histamine, a chemical released by the body during an allergic reaction. While its primary purpose is to alleviate allergy symptoms like itching, sneezing, and runny nose, a common side effect is drowsiness. This sedative effect is the reason many pet owners wonder, “Will my dog fall asleep with Benadryl?“
Why Drowsiness Occurs
The drowsiness associated with Benadryl arises from its anticholinergic properties. This means it blocks the action of acetylcholine, a neurotransmitter involved in various bodily functions, including wakefulness. By blocking acetylcholine, Benadryl can have a calming or even sedative effect on some dogs.
Benadryl for Dogs: Benefits Beyond Sleep
While the question ” Will my dog fall asleep with Benadryl?” focuses on sleep, it’s important to understand its broader applications:
- Allergy Relief: Benadryl is effective in treating mild to moderate allergic reactions, such as those caused by insect bites, pollen, or food.
- Motion Sickness: It can help prevent motion sickness in dogs during car rides or other travel.
- Anxiety Relief: In some cases, Benadryl can help calm mildly anxious dogs, especially in situations like thunderstorms or fireworks.
- Itch Relief: Benadryl can help alleviate itching associated with allergies or skin conditions.
Factors Influencing Benadryl’s Sedative Effects
Several factors determine whether a dog will become drowsy after taking Benadryl:
- Dosage: Higher doses are more likely to cause drowsiness, but never exceed the recommended dosage provided by your veterinarian.
- Individual Sensitivity: Just like humans, dogs have varying sensitivities to medications. Some dogs are naturally more prone to drowsiness than others.
- Age and Health: Senior dogs or those with certain health conditions may be more susceptible to the sedative effects of Benadryl.
- Breed: Some breeds may be more sensitive to the effects of Benadryl.
- Underlying Condition: If the dog is already tired or unwell due to the underlying allergic reaction or other condition, the sedative effects of Benadryl might be more pronounced.
Administering Benadryl Safely
- Consult Your Veterinarian: Always consult with your veterinarian before giving Benadryl to your dog. They can determine the appropriate dosage and ensure it is safe for your dog’s specific health condition.
- Follow Dosage Instructions Carefully: Adhere strictly to your veterinarian’s dosage instructions.
- Monitor Your Dog: Observe your dog for any adverse reactions, such as excessive drooling, vomiting, or difficulty breathing.
- Use Plain Benadryl: Ensure that you are using plain Benadryl containing only diphenhydramine as the active ingredient. Avoid products with added decongestants or other medications that could be harmful to dogs.
What To Do if Your Dog Doesn’t Get Drowsy
If your dog doesn’t become drowsy after taking Benadryl, it doesn’t necessarily mean the medication isn’t working. It simply means that the sedative effect isn’t prominent in your dog’s case. The medication can still be effectively alleviating allergy symptoms without causing significant drowsiness. If symptoms persist and you’re concerned, consult with your veterinarian about alternative treatment options.

Benadryl typically starts to work within 30 to 60 minutes after administration. The effects usually last for 4 to 6 hours.
What are the side effects of Benadryl in dogs?

Consult your veterinarian before giving Benadryl if your dog is already taking other medications. Benadryl can interact with certain drugs, potentially leading to adverse effects.
Will Benadryl stop my dog’s itching completely?

Can I give Benadryl to my puppy?

Is there a better alternative to Benadryl for my dog’s allergies?
Depending on the severity of your dog’s allergies, your veterinarian may recommend alternative treatments, such as prescription antihistamines (e.g., cetirizine, loratadine), corticosteroids, or allergy shots. These options may be more effective for some dogs.

Benadryl is generally given every 8-12 hours as needed for allergy symptoms. However, it’s best to follow your veterinarian’s specific recommendations regarding frequency and duration of treatment.
My dog is still restless after taking Benadryl. What should I do?
If your dog remains restless after taking Benadryl, it’s possible that the medication isn’t effective for that particular issue, or the dosage isn’t sufficient. Contact your veterinarian to discuss alternative treatment options. Consider if another underlying issue is contributing to the restlessness (e.g., pain, anxiety unrelated to allergies) so that you can properly address the issue.
