Skin fold pyoderma impetigo is a big one. Folliculitis, furunculosis, and cellulitis also fall under their purview. Urinary tract infections? They can handle those too.

Dosage and Administration

The recommended dose is 22 mg/kg (10 mg/lb) of body weight twice daily for 28 days.

Appropriate culture and susceptibility tests should be performed before treatment to determine the causative organism and its susceptibility to cephalexin. Therapy with RILEXINE Chewable Tablets may be initiated before the results of these tests are known; once the results become available, antimicrobial therapy should be adjusted accordingly. If the acceptable response to treatment is not observed, then the diagnosis should be reevaluated and appropriate alternative therapy considered.


RILEXINE Chewable Tablets are contraindicated in dogs with a known allergy to cephalexin or the β-lactam (any of the penicillins or cephalosporins) group of antibiotics.


For use in dogs only. Not for use in humans. Keep this drug out of the reach of children. Antimicrobials, including penicillins and cephalosporins, can cause allergic reactions in sensitized individuals. Sensitized individuals handling such antimicrobials, including cephalexin, should avoid contact of the product with the skin and mucous membranes to minimize the risk of allergic reactions.

In case of ingestion by humans contact a physician immediately. Physicians may contact a poison control center for advice concerning cases of ingestion by humans.

To obtain a copy of the Safety Data Sheet (SDS), or to report adverse reactions, call Virbac at 1-800-338-3659.


Prescribing antibacterial drugs in the absence of a proven or strongly suspected bacterial infection is unlikely to provide benefit to treated animals and may increase the risk of the development of drug-resistant animal pathogens.

RILEXINE Chewable Tablets are designed to taste good. Store RILEXINE Chewable Tablets out of reach of dogs, cats, and other pets in a secured location. Post-approval experience has shown that dogs and cats may willingly consume more than the recommended dosage of RILEXINE Chewable Tablets, which can result in overdose. Adverse reactions may occur if large quantities of tablets are ingested (see Adverse Reactions, Animal Safety, and Information for Dog Owners sections). If the product is dispensed in a container other than the original, prescribers should consider adding a statement on the bottle label reminding the owner that RILEXINE Chewable Tablets are designed to taste good and should be stored out of reach of pets in a secured location.

The safe use of RILEXINE Chewable Tablets in dogs intended for breeding and in pregnant or lactating bitches has not been evaluated.

Positive direct Coombs’ test results and false positive reactions for glucose in the urine have been reported during treatment with some cephalosporin antimicrobials. Cephalosporin antimicrobials may also cause falsely elevated urine protein determinations. Some antimicrobials, including cephalosporins, can cause lowered albumin values due to interference with certain testing methods.

Occasionally, cephalosporins have been associated with myelotoxicity, thereby creating a toxic neutropenia1. Other hematological reactions observed with cephalosporin therapy include neutropenia, anemia, hypoprothrombinemia, thrombocytopenia, prolonged prothrombin time (PT), and partial thromboplastin time (PTT), platelet dysfunction, and transient increases in serum aminotransferases2.

Storage Information:

Store at 20°C-25°C (68°F-77°F), with excursions permitted between 15°C-30°C (59°F-86°F).

Do not let children access this. Avoid using in animals with a known hypersensitivity to penicillin. Not suitable for use in rabbits, guinea pigs, hamsters, and gerbils. Just like with other antibiotics that are primarily eliminated by the kidneys, the body may experience excessive build-up if kidney function is compromised. If renal insufficiency is present, the dose should be decreased. Do not let children access it. If you are aware that you are sensitized or allergic to cephalexin, other cephalosporins, penicillin, or any beta-lactam antibiotic, use extreme caution and proper precautions while handling this product. If you have any doubts about a potential sensitivity, get in touch with your doctor or pharmacist. Manage this product in a way that allows you to prevent any exposure, following all suggested precautions. Clean your hands after using. If you experience symptoms like a skin rash after being exposed to something, it's important to seek medical assistance and share this warning with the doctor. Symptoms such as facial swelling, lip swelling, or difficulty breathing are more severe and demand immediate medical care.
