Oxytetracycline (Ophthalmic)
別名: Terramycin, Engemycin, Oxycare
* **Administration:** Wash hands before and after application. Do not allow the tip of the tube to touch the eye, eyelids, or any other surface to prevent contamination. * **Duration:** It is critical to continue treatment for the full 3-4 weeks as directed, even if the eye looks completely normal after a few days. Stopping early can lead to a relapse of the infection. * **Expectations:** You should see dramatic improvement in your cat's eye within 3 to 4 days. * **Note:** Your veterinarian may recommend an oral medication (like doxycycline) instead of or in addition to this ointment to fully clear the infection from your cat's system.
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。
