Customer Reviews
Surolan is rated 4.8 out of 5 by 5.
Rated 5 out of 5 by from Thanks Goodness for this! My dog had a really bad ear infection and was shaking her head non stop for hours until we got her to the vet. This medication started working in 3 Days She seemed completely healed but still used for the rest of the directed time of usage. I even used the remaining for a second ear infection(she swims a lot) even though I know I’m not supposed to do that and I got great results again! Hooray!

Rated 5 out of 5 by from Stuff is a Lifesaver for My Jack Russell Noticed my puppy was shaking his head quite violently at times, took him to the vet and found he had an ear infection, vet prescribed this and after two days his shaking of the head has already subsided so I assume the stuff is working quite well.

Rated 4 out of 5 by from This product is great for Cockers I clean my cocker's ears every 7 to 10 days with ear wash and use the non-alcohol canine ear wipes a couple of times a week for maintenance but every few months she'll get stinky, yeasty ears. My vet has prescribed several different treatments but none have worked as well as the Surolan drops. On day 3 she stopped scratching and rubbing them and by day 4 the smell was completely gone. After the 7 day treatment was completed I cleaned them out really good and to my surprise there was very little discharge. Note - Please use 2x/day for 7-full days...don't stop the treatment when there's improvement.

Rated 5 out of 5 by from This product works great The rottweiler, who happens to be a chihuahua-terrier mix, had always fought ear infections but after just two days on this medicine I could see a drastic improvement. The swelling in his ear canal went down and the redness was going away. After just one week he was no longer shaking his head or rubbing his ears on the ground. It was awful to see him so miserable and this medicine has been a life saver

My vet recommended I use it for 2 wks?  It says on the package instructions just 1 wk! Sometimes they get a little carried  away at Banfield pet hospital.  Is 2 wks too long?? He just has a "light ear infection ".

Asked by: Bubby
We recommend that this medication be used exactly as prescribed by your veterinarian. He/she may have prescribed this medication to use for a longer period of time in order to ensure eradication of the organism and prevent reoccurrence of the ear infection.

My dog is diabetic, can he still use sulfur an ear drops?

Asked by: Mo74
Yes he can! Administering an ear drop will have minimal systemic absorption and should not affect his diabetes.

Is Surolan safe in diabetic dogs?

Asked by: Mo74
Surolan is fine to use in a diabetic dog. It is administered in the ear, so systemic absorption will be minimal.
