Benadryl For Cats Suffering With Allergies

(redirects here from diphenhydramine, dramamine)

The following article details the dosage, side effect and safety information of Benadryl for cats.

Benadryl is a well-known OTC medicine often used to treat allergies and insomnia. The most typical active ingredient of Benadryl in many countries including the United States is diphenhydramine, which can also be found in Dramamine, a motion sickness preventative. Whilst it has proved to be a very helpful substance in the treatment of humans, can our pets enjoy the same benefits?

Benadryl dosage for cats

The standard recommended dosage of Benadryl for cats is 1 mg per pound to be given twice a day (every 12 hours). Many times your vet will ask you to start at a lower dosage such as 0.5 mg per pound and work your way up depending on how your pet reacts to the drug. For most cats, 0.5 mg of Benadryl per pound will be enough to curb their symptoms to a manageable level. You should never exceed the maximum dosage or give more than is necessary.

Given the information above, we can deduce a starting dose of 5 mg of Benadryl twice a day for a 10 lb cat, moving up to 10 mg twice a day if symptoms persist.

Is Benadryl safe for cats?

Benadryl, when it contains the single active ingredient diphenhydramine, is safe for use in many household pets including cats and dogs. However, many Benadryl formulations contain the wrong active ingredient and may be dangerous for your feline friend. Because of this, it is strongly recommended that you seek veterinary approval before giving the drug to your cat.

Safety precautions:

  • Be sure that any other medication your cat is taking does not interact with Benadryl
  • Notify your vet of all illnesses your cat suffers from, especially heart disease, glaucoma, prostatic disease or hyperthyroidism
  • Opt for the pill form of the medication due to the alcohol content of liquid Benadryl
  • Never mix with erythromycin or allopurinol

After you have checked the packaging carefully to ensure that diphenhydramine is the only active ingredient and have ran it through with your vet, you should administer the recommended Benadryl dosage for cats as discussed earlier. If you notice any serious negative side effects develop after using the drug, though extremely rare at safe dosages, seek emergency veterinary care.

There are many other popular alternatives to Benadryl which may be used to curb your cat’s symptoms such as Claritin.
