What is Benadryl and what it is used for?
Benadryl is an antihistamine medication mainly used to relieve symptoms of allergic reactions. When encountering specific allergens (dust, grass, plastic, pollen, fungi, etc.), your cat's immune system may release histamines and other chemicals, which can cause allergic symptoms, such as:
- Coughing and wheezing;
- Itchy skin (excessive scratching and overgrooming);
- Vomiting and diarrhea; and
- Gas and bloating.
Antihistamines, including Benadryl, decrease the body's response to histamines and alleviate the above-mentioned symptoms. Besides relieving allergic symptoms, your veterinarian may recommend Benadryl for other medical reasons, such as anxiety and the prevention of motion sickness and nausea.
Note that if your cat is experiencing anaphylaxis (severe allergic reaction that is distinguished by difficulty breathing, facial swelling, seizures, or collapse), Benadryl may not be of help — you need to take your cat to the nearest veterinarian clinic urgently. 🏥
🙋 Benadryl is a brand name for diphenhydramine (antihistamine). Other brand names for diphenhydramine that you may find on the U.S. market are Vetadryl, Banophen, Genahist, Diphenhist, Unisom, and Sominex.

How much Benadryl can I give my cat?
Now that we have established how our calculator works, let's talk about calculating Benadryl dosage for cats by weight. Ensuring that our furry friends receive a safe amount of medication is very important.
Q: How much Benadryl can I give my cat?
A: Veterinarians recommend approximately one milligram of Benadryl per pound of body weight.
Benadryl dosage in mg = cat's weight in lb * 1mg
Meaning, if you have a 10-pound (approximately 4.5 kg) cat, you should give it 10 mg of Benadryl.
Q: Is liquid Benadryl safe for cats?
A: Yes! You can give your cat liquid Benadryl, and sometimes it is easier to measure as well. If you're giving your 10-pound cat Liquid Benadryl with 12.5 mg per 5 ml concentration, you should carefully measure out 4ml of liquid. Why 4ml? Let's calculate:
First, you need to calculate the number of milligrams you would give your 10-pound cat:
Benadryl dosage in mg = 10 lb * 1 mg
Then you should milligrams into milliliters (remember that liquid concentration is 12.5 mg per 5 ml).
12.5 mg / 5 ml = 2.5 mg/ml
Lastly, you need to divide the weight of our cat by 2.5 ml:
10 / 2.5 = 4 ml
Therefore, 4 ml of liquid Benadryl would be a safe dose for your 10 lb cat!
