What is a Generic Drug?

A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.

The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.

Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.

    Directions

    Otomax ointment is used in the ears of dogs only.

    Otomax ointment is available in 7.5 gram and 15 gram tubes. It is also available in 15 gram, 30 gram, and 215 gram plastic bottles.

    Follow the instructions that come with your dog's Otomax ointment prescription. Talk to your veterinarian or pharmacist about any questions or concerns you may have.

    Before administering Otomax ointment, clean and dry your dog's external ear. Inspect and remove any foreign materials or debri using appropriate non-irritating solutions. Clip any hair away from the treatment area. Make sure your dog's eardrum is intact. This will prevent damage to the cochlea or vestibular apparatus and prevent a middle ear infection from developing.

    Dogs weighing less 30 pounds:

    If using the 7.5 gram or 15 gram tube, or the 15 gram or 30 gram bottle, place 4 drops of Otomax ointment into your dog's ear canal two times a day. If using the 215 gram bottle, place 2 drops into your dog's ear canal two times a day. To make sure your dog receives the appropriate dose of medication, massage your dog's external ear canal. Continue treatment for 7 days.

    Dogs weighing 30 pounds or more:

    If using the 7.5 gram or 15 gram tube, or the 15 gram or 30 gram bottle, place 8 drops of Otomax ointment into your dog's ear canal two times a day. If using the 215 gram bottle, place 4 drops into your dog's ear canal two times a day. To make sure your dog receives the appropriate dose of medication, massage your dog's external ear canal. Continue treatment for 7 days.

    Ingredients

    Gentamicin sulfate, an antibiotic, betamethasone valerate, a synthetic adrenocorticoid, and clotrimazole, an antifungal, are the active ingredients contained in Otomax ointment.

    Contraindications

    Do not use Otomax ointment if your dog is allergic to any of its ingredients. If your dog has a reaction to Otomax ointment, stop using it and contact your veterinarian. 

    Do not use Otomax ointment with other medications that can cause hearing damage.

    Do not use Otomax ointment if your dog has perforated eardrums.

    Cautions

    • Do not use Otomax ointment in humans.
    • Before you dog begins treatment with Otomax ointment, it's important to discuss the following with your veterinarian:
      • Your dog's medications, including supplements
      • Your dog's allergies
      • Your dog's medical problems
      • If your dog is pregnant or you plan to breed your dog
      • If your dog is nursing
    • Do not allow your dog to ingest Otomax ointment.
    • Otomax ointment may cause deafness or temporary hearing loss. If you notice changes in your dog's hearing, stop Otomax right away and flush your dog's ear canal with a nontoxic solution. 
    • The use of corticosteroids may cause harm to an unborn puppy. 

    Side Effects

    Otomax ointment may be associated with side effects such as elevated SAP and SGPT enzymes, hearing problems, kidney problems, weight loss, thirst, production of large amounts of urine, diarrhea (may be blood), vomiting, and skin redness, irritation, blistering, stinging, peeling, swelling, itching, or pain.
