Cephalexin
別名: Keflex, Ceporex, Cefalexina, Cefaseptin, Cephacare, Cephorum, Rilexine, Therios, Tsefalen
**Cephalexin** is a commonly prescribed antibiotic used to treat bacterial infections, especially skin infections (pyoderma). * **Administration**: Can be given with or without food. **If your pet vomits or acts sick after receiving the dose, try giving it with a small meal or treat.** * **Finish the Course**: It is critical to give the medication for the entire time prescribed by your veterinarian, even if your pet seems completely better. Stopping early can lead to resistant infections. * **Allergic Reactions**: Though rare, allergic reactions can occur. Contact your veterinarian immediately if you notice facial swelling, hives, severe scratching, sudden diarrhea, or difficulty breathing. * **Storage**: Store capsules and tablets at room temperature. If you were given a liquid suspension, follow the storage instructions on the bottle (usually stable for 14 days after mixing).
劑量必須由獸醫按你寵物的個別情況決定。切勿在沒有獸醫指導下給予人類藥物或其他寵物的處方藥。

可能的副作用
- Gastrointestinal upset (anorexia, vomiting, diarrhea)
- Hypersensitivity reactions (rashes, fever, eosinophilia, anaphylaxis)
- Salivation, tachypnea, and excitability (reported in dogs)
- Emesis and fever (reported in cats)
- Nephrotoxicity (rare)
- Toxic epidermal necrolysis (rarely reported in cats)
- Antibiotic-associated diarrhea or gut flora alteration
注意事項與禁忌
- Known hypersensitivity to cephalosporins
- Patients with septicemia, shock, or grave illness (oral absorption is unreliable; parenteral routes preferred)
- > **Hypersensitivity Cross-Reactivity**: Use with caution in patients with documented hypersensitivity to other beta-lactam antibiotics (e.g., penicillins, carbapenems), as cross-reactivity can occur. * **Renal Impairment**: Use cautiously and consider dose reduction in patients with renal dysfunction or those receiving concurrent nephrotoxic drugs. * **Critically Ill Patients**: Do not use oral systemic antibiotics in patients with shock or septicemia due to delayed or diminished GI absorption. * **Laboratory Interference**: May cause false-positive urine glucose tests (with cupric sulfate solutions like Clinitest) and falsely elevated serum/urine creatinine (with Jaffe reaction).
藥物相互作用
- Probenecid: Competitively blocks the tubular secretion of cephalosporins, thereby increasing serum levels and prolonging serum half-lives.
- Aminoglycosides: Increased risk of nephrotoxicity. Do not mix in the same syringe.
- Amphotericin B: Increased risk of nephrotoxicity.
- Loop diuretics (e.g., furosemide): Increased risk of nephrotoxicity.
