Can Cats Have Benadryl to Calm Them Down? A Veterinarian’s Perspective
Giving your cat Benadryl to calm them down is potentially dangerous and should only be done under the direct guidance of a veterinarian. While Benadryl (diphenhydramine) can sometimes be used to treat certain conditions in cats, its calming effects are unreliable and side effects can be serious.
Understanding Benadryl (Diphenhydramine)
Benadryl is an antihistamine that works by blocking histamine receptors in the body. Histamine is a chemical released by the body during an allergic reaction. By blocking histamine, Benadryl can help relieve symptoms such as itching, sneezing, and runny nose. Can cats have Benadryl to calm them down? While this medication is readily available over the counter, the answer isn’t a straightforward “yes.”
Potential Uses of Benadryl in Cats
While calming a cat isn’t a primary use of Benadryl, it can be prescribed by a veterinarian for a few specific reasons, including:
- Allergic Reactions: Mild skin allergies, insect bites, or reactions to vaccines.
- Motion Sickness: Some vets prescribe it to help prevent motion sickness during travel.
- Anxiety: In very limited cases and only under strict veterinary supervision, it might be used for mild anxiety.
It’s crucial to understand that Benadryl is not a reliable sedative for most cats. Its effects can vary widely.
Why Benadryl Isn’t a Reliable Sedative
The primary reason Benadryl isn’t reliably used for sedation is its unpredictable effect on cats. Some cats experience drowsiness, while others become hyperactive or agitated. This paradoxical reaction is common and makes it an unsafe choice for calming cats without veterinary guidance. Moreover, there are safer, more effective calming medications specifically formulated for feline use.
Risks and Side Effects of Benadryl in Cats
Giving Benadryl to your cat without consulting a vet carries several risks:
- Side Effects: Possible side effects include drowsiness, dry mouth, increased heart rate, urinary retention, and agitation.
- Overdose: An overdose of Benadryl can be serious, leading to seizures, coma, and even death.
- Underlying Conditions: Benadryl can worsen certain underlying conditions, such as glaucoma, heart disease, and high blood pressure.
- Drug Interactions: Benadryl can interact negatively with other medications your cat might be taking.
It’s vital to always consult your veterinarian before administering any medication to your cat, even over-the-counter drugs like Benadryl. It is unsafe to assume can cats have Benadryl to calm them down? without professional opinion.
Dosage Guidelines and Administration
If your veterinarian prescribes Benadryl for your cat, they will provide specific dosage instructions based on your cat’s weight, age, and health condition. It is crucial to follow these instructions precisely. Never guess at the dosage or administer more than prescribed.
- Typically, the recommended dosage is between 1-2 mg per pound of body weight, given two to three times daily.
- Benadryl is available in tablet, liquid, and capsule form. Your veterinarian can advise on the best formulation for your cat.
- Liquid formulations may contain alcohol, which is toxic to cats. Therefore, always check the ingredients and choose an alcohol-free option.
Safer Alternatives for Calming Your Cat
Instead of resorting to Benadryl, consider these safer and more effective alternatives for calming your cat:
- Pheromone Products: Feliway diffusers and sprays mimic natural feline pheromones that create a sense of calm and security.
- Supplements: L-theanine and Zylkene are natural supplements that can help reduce anxiety in cats.
- Prescription Medications: Your veterinarian may prescribe anti-anxiety medications specifically formulated for cats, such as fluoxetine or alprazolam.
- Environmental Enrichment: Providing a stimulating environment with plenty of toys, scratching posts, and climbing structures can help reduce boredom and anxiety.
- Behavioral Therapy: A certified feline behaviorist can help identify the underlying causes of your cat’s anxiety and develop a customized treatment plan.
When to Seek Veterinary Care
Contact your veterinarian immediately if:
- Your cat experiences any adverse reactions after taking Benadryl, such as difficulty breathing, seizures, or collapse.
- Your cat’s anxiety or agitation worsens after taking Benadryl.
- You are unsure about the correct dosage of Benadryl for your cat.
- Your cat has any underlying health conditions.

Can I use children’s Benadryl for my cat?

Therefore, it’s best to avoid using children’s Benadryl and opt for a formulation specifically recommended by your veterinarian.
Are there any cats who should NOT take Benadryl?
Yes, Benadryl should be avoided in cats with certain underlying health conditions, such as glaucoma, heart disease, high blood pressure, and urinary retention. Additionally, cats taking certain medications may experience adverse interactions with Benadryl. Always consult your veterinarian before giving Benadryl to your cat, especially if they have any pre-existing health conditions.
What if Benadryl makes my cat more hyperactive instead of calming them down?
Some cats experience a paradoxical reaction to Benadryl, becoming more hyperactive or agitated instead of drowsy. If this happens, stop giving Benadryl and contact your veterinarian for alternative solutions.
How can I give Benadryl to my cat if they refuse to take it?
Hiding the tablet in a pill pocket or a small amount of wet food can help make it easier to administer. Liquid formulations can be mixed with a small amount of food or water. If your cat continues to resist, ask your veterinarian for alternative administration methods.
Is it OK to use Benadryl long-term for my cat’s anxiety?
Long-term use of Benadryl for anxiety is generally not recommended. It is not a sustainable solution and may lead to tolerance or adverse side effects. Discuss safer and more effective long-term anxiety management options with your veterinarian.
What are some natural alternatives to Benadryl for calming my cat?
Natural alternatives include pheromone products (Feliway), supplements like L-theanine and Zylkene, and creating a calm and enriching environment for your cat. These methods are generally safer than Benadryl for long-term anxiety management.
Can cats have Benadryl to calm them down before a vet visit?
While the impulse to calm a nervous cat before a vet visit is understandable, using Benadryl without veterinary guidance is risky. Always consult your veterinarian beforehand. They may recommend a small dose of a prescribed anti-anxiety medication specifically for this purpose, if deemed necessary and safe for your cat.
