No — cefovecin is not a penicillin. It is a third‑generation cephalosporin antibiotic (brand name Convenia) used in veterinary medicine.

Both penicillins and cephalosporins are beta‑lactam antibiotics and work similarly (inhibit bacterial cell‑wall synthesis), but they are different classes with different chemical structures and spectra of activity. Cross‑reactive allergic reactions between penicillins and cephalosporins are possible but less common than once believed; the risk is low but not zero, so caution is warranted if there is a known severe penicillin allergy. Cefovecin is licensed for use in dogs and cats (long‑acting injectable) and is not used in humans. If you’re concerned about allergy or appropriate use, consult your veterinarian.
