What is Diphenhydramine?

How it works:
Diphenhydramine comes in 25mg minitabs or 50mg capsules, and is a generic version of Benadryl. As an antihistamine, it counteracts the effect of histamine, which causes symptoms like itching and sneezing.

Diphenhydramine (Generic Benadryl) 4.1 5 48 48
DIPHENHYDRAMINE product review: One of the oldest antihistamines around(brand name benadryl), this economic generic version, has as much of a chance at providing symptomatic relief, as many of the newer and more expensive antihistamines that have emerged in recent years, in my experience and opinion. I usually will dose this medicine at anywhere between one half to 1 mg per pound once to twice daily for chronic cases. For those frustrating seasonal allergy cases that can often result in endless itching and secondary bacterial skin and ear infections, the mild sedative effect is also helpful in calming dogs down during difficult allergy seasons. It will help to some degree in 25% of cases in my experience, but when I combine its use with an essential omega 3 fatty acid supplement like Super pure Omega 3 or nordic naturals pet cod liver oil, the clinical response rate in terms of symptom relief certainly climbs in my practice. I also like to use at the same time the antioxidant supplement proanthozone as well, whose nonsedative antihistamine effect can also help when used with diphenhydramine. Keeping in mind that many of these allergy cases are due to contact allergens as well, regular shampooing once to twice weekly with the soothing 1800petmeds oatmeal and aloe shampoo can also be helpful in these pets, in addition to diphenhydramine, essential fatty acids and proanthozone. Another wonderful use of diphenhydramine in pets, which also makes it an indispensable part of an animal guardian's pet medicine cabinet, is in those pets prone to sudden allergic reactions such as spider bites or bee stings, especially during the warmer seasons. Animal guardians can often save lots of money on expensive vet visits when a pet comes in from the outside with a swollen muzzle by giving diphenhydramine at a dose of 1 mg per pound every 6-8 hours as needed for the first 24 hours after such an acute reaction. This would also apply for acute vaccination reactions as well. Of course if ever in doubt during these acute sudden reactions, veterinary exam and consultation is always recommended. For more long term skin allergy use, clients need to understand, however that sometimes one type of antihistamine will work in one dog or cat and not in another, so that if there is not adequate improvement with the protocol described here over 10-14 days, I will often try a different antihistamine like chlorphenirimine or clemastine, also available from the 1800petmeds website. My overall rating of this product is a 4. Its ease of use a 5, and efficacy a 3.5, particularly when combined with the other supportive measures described here. 01/13/2009
Disappointed with effectiveness My lab mix has terrible skin allergies and her vet suggested giving her generic Benadryl. It worked marginally for awhile and then it eventually didn't seem to help. I was hoping this product was stronger or different from Benadryl, but it is not. It has exactly the same ingredients and dosage as the Benadryl. It was a waste of my money. 09/27/2014
Generic Benadryl ROCK, my (Pitbull) has allergy issues. He is given his antihistamine every moring and he is feeling so much bettet. The runny nose, itching and over all allergy discomfort is 100% better. I highly recommend this product. 09/16/2014
Capsules are a high dose This dose is to high for a 17 Lbs dog, spoke with my Vet and she said this dose should be broken up into 3 doses. So If you have a 50 Lbs+ pet this is fine otherwise you are over medicating you pet. 17 Lbs. = 1 tsp. benadryl 05/09/2014
Helps control sneezing and coughing from allergies Spunky is a small (17 lbs.) Cairn Terrier/Poodle mix. Without antihistamine he develops sneezing as well as nasal congestion, followed by coughing. Taken twice daily, one Diphenhydramine works so sneezes are productive to help clear his nose and chest. The tablet works quickly to clear the mucous. I have seen no bad side effects for Spunky 05/03/2014

Answer: 
The recommended dose is 0.5 - 2mg per lb of pets body weight every 8 -12 hours. If your pet weighs
25 pounds the dose is 12.5mg to 50mg every 8 to 12 hours. The medication may cause drowiness so it is better to start low and work the dose up to the desired effect like giving 1/2 of a 25mg tablet every
12 hours.

Answer: 
Benadryl can help with allergies however the symptoms your cat is experiencing are a concern as there may be a respiratory infection present. Please consult with your veterinarian prior giving the Benadryl in case your pet has an infection.

Answer: 
I also have a hard time getting pills into my cat and dog, even after trying the Pill Pockets (they love the taste but after they figure out there's a pill inside they won't fall for it. My vet finally told me about this device available at pet stores, not sure what it's called-perhaps a "pill stick?". It looks like a long syringe (no needle) with a space at the end for the pill, and you just gently use your fingers at the corners of the pet's mouth to pry open his jaw. Then quickly stick the device in over his tongue to the back of his throat and when you push the plunger, the pill goes in. I always hold the muzzle upward for a few seconds and massage the throat to make sure they swallow. It helps to have a 2nd person, and a towel to wrap up a cat, but I can now do my dog easily by myself.

Answer: 
we sell the diphenhydramine 25 mg in a tablet form. For a 9 lb cat , a middle of the range dosse
would be to give 1/2 of the 25 mg minitab every 8 to 12 hours depending on how often the
cat needs it. The minitab we sell is easy to break in half, especially with a pill cutter.
Hide the 1/2 tablet in a snack the cat really loves before meal time when the cat is really
hungry. You can also use Pill pockets for cats which are chicken flavored or use some wet
food to roll around the medicine.
