Dosage and administration

This product is for topical administration. Shake the bottle well and ensure the product is fully resuspended before use. At the beginning of treatment, hair surrounding or covering the lesions must be clipped; this should be repeated during treatment if necessary.


Clean the auditory canal and place a few drops of the product into the ear twice daily. For infections caused by Otodectes cynotis, instill five drops twice daily for 14 days. Massage the ear and the auditory canal gently but thoroughly to ensure proper distribution.


Having ensured the area to be treated is clean, apply a few drops of the product (depending on lesion size) twice a day and rub well.

Treatment should be continued until a few days after complete disappearance of the clinical symptoms. In some obstinate cases, 2 to 3 weeks treatment may be necessary.

Where ear mite infestation is present, consideration should be given to treating both ears even if infestation is only apparent in one ear.

Contra-indications, warnings, etc

Do not use in animals with perforated ear drums since polymyxin B is known to be a potential ototoxic agent.

Long term use of topical steroids may cause skin thinning and delay wound healing. Corticosteroids are not recommended for use in pregnant animals.

As Surolan is a prescription only medicine, treatment should be closely supervised by a veterinary practitioner. Due to likely variability (time, geographical) in the occurrence of resistance of bacteria for polymyxin B, bacteriological sampling and susceptibility testing are recommended.

For external use only.


The product is applied topically. No toxic side effects have been observed after accidental intake by licking.

Further information

Miconazole nitrate is a synthetic imidazole derivative with a pronounced antifungal activity and a potent activity against Gram-positive bacteria. Miconazole selectively inhibits the synthesis of ergosterol, which is an essential component of the membrane of yeasts and fungi.

Polymyxin B sulphate is a polypeptide antibiotic with batericidal activity against Gram-negative bacteria. It binds to phospholipids in the cytoplasmic membrane, whereby the membrane permeability is disturbed. This results in lysis of the bacteria.

Prednisolone acetate is a glucocorticoid with strong anti-inflammatory activity which results from its reduction of the permeability of capillaries and vascular proliferation and from the inhibition of fibroblast action.

After topical application of miconazole nitrate virtually no systemic absorption takes place through the skin or mucous membranes. Systemic absorption of prednisolone on normal or abraded skin is minimal. Absorption of polymyxin B via the skin is also negligible.

Ear drops

Is there an equivalent product to surolan that doesn't require a prescription please

John Cousins
  • Veterinary Surgeon

The short answer is no, there is not. Surolan is a mixture of antibiotics and a steroid and all of these are prescription only. You might find that your dog would respond well to daily cleaning with a simple, mildly antiseptic wash, such as Epi-otic. Some dogs do. Others have an underlying allergy which results in persistent or recurrent ear inflammation and secondary microbial overgrowth. An exclusion diet, fed for at least 6 weeks, will sometimes provide a cure for the ear trouble (surprisingly enough). Investigating a possible dietary allergy might well be worth talking to your vet about.
