"My cat got a double dose of Benadryl. Will she be okay?"

Question in title asked on Quora. Here is the answer. 

Benadryl, which is the brand name for the medication diphenhydramine, can be safe for cats in certain situations, but it is important to consult with your veterinarian before giving it to your cat. Benadryl can be helpful for allergic reactions, such as hives or swelling, and can also be used to help with motion sickness or anxiety.

However, it can also be toxic to cats if not given correctly. Cats can get diphenhydramine poisoning from ingesting too much Benadryl or from ingesting Benadryl that contains other ingredients, such as decongestants or pain relievers, which can be toxic to cats.

Here are some of the signs of diphenhydramine poisoning in cats:

• Vomiting
• Diarrhea
• Dilated pupils
• Loss of coordination
• Seizures
• Coma

If you think your cat has ingested Benadryl or is experiencing any of the signs of diphenhydramine poisoning, it is important to take them to the veterinarian immediately.

Important: Never give your cat Benadryl without first consulting with your veterinarian. Your veterinarian will be able to advise you on whether Benadryl is right for your cat and, if so, the correct dosage.
