Is Rilexine The Same As Cephalexin? Quick Answer

Rilexine generic name is "Cephalexin". Some folks are confused about the question "IS RILEXINE THE SAME AS CEPHALEXIN"?. So, before I answered the question, I just want to give a little but essential information about Rilexine Chewable Tablets

Rilexine is the registered trademark of Virbac USA. It contains an active ingredient Cefalexin well known as Cephalexin, a first-generation cephalosporin drug, which kills a broad range of gram-positive and some gram-negative bacteria. 


Rilexine Chewable tablets are not the same as Cephalexin (Keflex or other brands approved to use in humans).

Now, I get back to our primary question, "What is the difference between Rilexine and Cephalexin"? So, below is a detailed note on that question.

Rilexine Vs Cephalexin


It's the FDA (Food and Drug Administration) approved cephalosporin antibiotics to treat Pyoderma of the dogs caused by Staphylococcus pseudintermedius bacteria. Pyo means PUS, and Derma means SKIN. So, all skin infections where pus is present, like skin fold pyoderma impetigo, cellulitis, folliculitis, etc. Rilexine (cephalexin) is used to drain pus, and to treat skin infection.

It is available in chewable form, in 3 different sizes, liver-flavored for dogs. And it's highly acceptable by the pets. A regular study observed that over 80% of dogs voluntarily eat these rilexine chewable tablets.

Rilexine Dosage for Dogs

Rilexine is available in four dosage strengths, 75mg, 150mg, 300mg and 600mg dose. The recommended dosage of Rilexine for pets is 22mg/kg or 11mg/lb for dogs. Always consult your Veterinarian doctor before using any medicine. Rilexine is veterinary medicine and should be used in humans. Keep it in a cool, dry place. keep out of the reach of children.


This is basically a generic name of a drug. Keflex is the brand name of "Cephalexin". Keflex is not FDA-approved to use in animals or canines. It should be used in humans to treat skin infections, urinary tract infections, upper respiratory tract infections, ear infections, eye infections, nose infections, and other wounds that contain pus.

Keflex Dosage For Humans

A doctor may suggest the best dosage plan after diagnosing the infection type and severity of the infection. You must follow your doctor, physician, or pharmacist instructions carefully. Overdose may result in the side effects of this medicine.
