Ketoconazole dosage for a 13lb dog with a Malassezia yeast infection?

Hello and thank you for your post! I have used Fluconazole multiple times for yeast infections and 200mg twice daily is within the dosing range. I would discuss this with your prescribing veterinarian first before switching as different drugs are used in different circumstances. In my experience, Fluconazole has less side effects than Ketoconazole and I prefer Fluconazole. I do not know what concentration your amoxicillin syrup is, but if it is just a yeast infection, an antibiotic like amoxicillin is not going to help. Levofenil is a human product and has not been tested for use in animals, so I would avoid using this solution for treating Milo. I would recommend bathing Milo twice weekly with Duoxo Chlorhexidine PS combination shampoo until resolved. This shampoo will treat bacterial and fungal skin infections and it does so quite well. I hope this helps! Please let me know if you have any other questions or concerns! I am also available via consultation if needed.

Assuming Bruno weighs more than 30lbs the dosage is actually borderline low, I personally do not like Fluconazole, I usually prefer to use Itraconazole which I find more effective and safer, but at this dosage you do not have to worry about any severe side effects.

Typically medications with the proper dose ad for a short period of time will not hurt the liver or kidneys. However any patient can be sensitive to medications. As long as Milo is eating, drinking and acting like her normal self I would not be concerned. IF she starts acting sick I would call the vet to discuss her medications and proper steps. Hope milo feels better soon

Hello, there are several oral medications used to treat fungal infections in dogs, including ketoconazole, fluconazole & itraconazole. All require a prescription from your veterinarian to treat a pet. Thanks for using Petco Pet Education Center, formerly Petcoach.

Yeast infections are especially itchy, crusty, and smelly. Often a dog starts with a rash or with simple itching but the skin thickens to an “elephant” skin appearance. The itch is extreme and the odor can be especially troublesome. Parts of the body or the entire body can be affected. Malassezia overgrowth is particularly problematic where there are skin folds ("armpits," eyelids, facial folds, lip folds, throat latch, and especially between the toes). Treatment can be topical, oral, or both. Topical treatment is best used for localized spots of infection while oral medication would be better applied to larger infected areas. If the yeast infection is recurrent or if one wishes to supplement oral medication, topical and oral treatment can be combined. Oral medications are available through your vet. Shampoos such as Chlorhexiderm Max® or Malaseb® shampoo both strip skin oil and kill yeast; however, other anti-yeast products include Selsun Blue®, Miconazole® shampoo, Nizoral® shampoo, Douxo® shampoo and more. The pet must be bathed twice a week to start and the shampoo requires a 15 minute contact time (meaning do not rinse the lather for 15 minutes). It is important to realize that yeast overgrowth occurs in response to a primary problem be it allergy, seborrhea or something else. If the underlying problem is not controlled, yeast dermatitis is likely to periodically recur. It is common for allergic dogs to require some kind of periodic if not on-going anti-yeast therapy.

Hello and thank you for contacting Petco Pet Education Center, formerly Petcoach. If the vet has confirmed that your dog has systemic fungal infection, then itraconazole is the right medication to use. Usually, dogs needs from 4 to even 15-18 weeks of treatment with itraconazole to completely get rid of bad fungal infections.

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern.
