Zymox Otic with hydrocortisone is used for the treatment of acute and chronic otitis externa, an inflammation of the outer ear characterized by itching, swelling, redness and pain in the outer part of the ears. Simply touching the ears of your pets can hurt. Zymox Otic is manufactured by PKB Animal Health, a well-known manufacturer of pet care and veterinary products. It is a proven antibiotic alternative and provides quick relief for your pet and also eliminates the bacteria and fungi that caused the infection. It is safe to use long-term and is especially beneficial for persistent cases of otitis externa. Zymox Otic without hydrocortisone is also available for those who are sensitive to hydrocortisone or those pets who are pregnant or lactating. It is important not to pre-clean your pet's ears before applying Zymox Otic. The ear may be gently wiped with a soft cloth to remove excess.
