What is Surolan?

Surolan is used to treat otitis externa and dermatitis in dogs caused by yeasts, fungi, bacteria and ear mites. Surolan requires a prescription from your veterinarian.



  • Effective treatment for otitis externa
  • FDA-approved
How it Works:

The ingredients in Surolan are a combination of antifungal, antibiotic, and anti-inflammatory agents including polymyxin B, miconazole and prednisolone to help treat otitis externa.


Not for use in humans. Keep this and all drugs out of reach of children. Do not administer daily. For otic use only. Examine the external ear canal thoroughly to be certain the tympanic membranes are not ruptured. If overgrowth of non-susceptible bacteria or fungi occurs, treatment should be discontinued and appropriate therapy instituted. The safe use of Surolan in dogs used for breeding purposes, during pregnancy, or in lactating bitches has not been evaluated.

Brand Name:

Surolan Otic Suspension (Elanco)

What is the most important information I should know about Surolan Otic Suspension:

Surolan Otic Suspension is a prescription medication FDA approved for use in dogs only. It is available in a 15 ml plastic dropper bottle. Use this medication for the full amount of time prescribed by your veterinarian, even if your pet appears to be better. Symptoms may improve before the infection is completely healed. Shake well before use. The usual dose for dogs of any weight is 5 drops placed into the ear canal 2 times a day and massage the ear. Therapy should continue for 7 consecutive days. Avoid getting this medication in your pet's eyes, nose or mouth.

What is Surolan Otic Suspension:

Surolan Otic Suspension is a combination of medications with antibacterial (polymyxin B sulfate), anti-inflammatory (prednisolone acetate) and antifungal (miconazole nitrate) activity. It is used in dogs for the treatment of canine otitis externa associated with yeast and/or bacteria susceptible to polymyxin B and miconazole. Surolan Otic Suspension may be used for purposes other than those listed in this medication guide.

What happens if I miss using a dose:

Apply the missed dose as soon as you remember. However, if it is almost time for the next dose, skip the dose you missed and apply the next regularly scheduled dose. Do not use a double dose of this medication unless otherwise directed by your veterinarian.

What happens if I overdose my pet:

An overdose of Surolan Otic Suspension is unlikely to occur. If you suspect that a much larger than normal dose has been used, or that the medication has been swallowed, contact your veterinarian or veterinary emergency room.

Surolan is rated 4.75 out of 5 by 4.
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 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.

can i use otic suspension prescription meant for dogs ears but use for eye infections as welldiana

Asked by: diana
no that is not advisable. Sometimes an eye medication can be used in the ear, but only eye products are designed in the sterile way needed for eyes and also with the right isotonic solutions so it doesnt sting the eye. BOTTOM LINE IS THAT WILL STING THE EYE SO DO NOT DO IT !!

please refer to question below ty

has suroyln ear medication been linked to seizures in dogs?
Asked by: lexi
That is not mentioned as a side effect or adverse reaction. It is a medication that works locally as opposed to systemically like an oral or IV medication. Speak to your vet immediately to help you determine the actual trigger of a seizure.

Can I use Surolan if my dog has an itchy ear?

My vet recommended me Surolan for my dog about 4 months ago, I used on my dog for 7 days and the problem was gone. However, now her ear seems to be itchy again and since I have half bottle of Surolan left can I use it on my pet without visiting the vet again?
Asked by: ChiaHao
You should always consult with your veterinarian before giving any antibiotis to your dog, the itching may or may not be due to an infection.

how long is surolan good for after openeing?

i opened my dog's surolan 4 months ago and she still has an otitis now. is the product still good?
Asked by: jess
The product should have an expiration date either on the box the bottle came in, or on the bottle itself. This is the date that the product should no longer be used. Also, if your pet is still having problems with its ear after 4 months, you should let your veterinarian know about this. Thanks for your question.
