Bests & Worsts Reviews from Amazon

I used this ear cleaner on a 17 year old dachshund with chronic renal failure and cataracts. She was maintaining well despite her problems but a few days after using this solution she started having tarry black stool and her cataracts severely worsened. I did an internet search and found that hydrocortisone can cause both of those problems. I immediately stopped usage and her stool is almost back to normal but now her eyes are in very poor shape, and when added to her other problems (deafness), will likely require us to put her down. In general, topically applied hydrocortisone is supposed to be safe, but the inside of a dog's ear has very thin skin (some pain medications are applied to the ear because of this, such as when we had her remaining teeth extracted). I'm sure her kidneys took longer to flush any of the hydrocortisone that got into her bloodstream too. This medication probably works well in most cases but I wanted to post this review as a warning to those seeking a cure for an elderly dog or a dog with other health complications. Try out a milder ear cleaner first, preferably one without the use of a corticosteroid.
