Rilexine is indicated for the treatment of various bacterial infections in dogs and cats, including superficial and deep pyoderma (skin infections), respiratory infections, urinary tract infections, and soft tissue infections. It may also be used for bone and joint infections in some cases.
As a first-generation cephalosporin, Rilexine inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs). This weakens the bacterial cell wall, leading to cell death. It is effective primarily against gram-positive bacteria such as Staphylococcus and Streptococcus species, with limited gram-negative coverage.
Rilexine is generally well-tolerated in dogs and cats, though side effects may include gastrointestinal upset such as vomiting or diarrhea. Animals with known allergies to penicillins or cephalosporins should not receive this medication. It should be used with caution in patients with renal impairment. Always complete the full course of treatment as prescribed by your veterinarian, even if symptoms improve earlier.
