Pharmaceutical Form

Clinical Particulars

Therapeutic Indications

For the treatment of otitis externa.

Posology and Method of Administration

Adults (including the elderly) and children 2 years of age and over

Discontinue treatment if there is no clinical improvement after 7 days (see section Special Warnings and Precautions for Use).

One metered dose (60mg) to be administered directly into each affected ear three times daily.

Treatment should be continued until two days after symptoms have disappeared.

Infants and neonates (under 2 years of age)

Otomize ear spray is not suitable for infants and neonates (see section Contraindications).


Hypersensitivity to neomycin sulfate, dexamethasone, glacial acetic acid or to any of the excipients.

The product should not be used in patients where a perforated tympanic membrane has been diagnosed or is suspected or where a tympanostomy tube (grommet) is in situ.

The product should not be used in infants and neonates under 2 years of age.

Special Warnings and Precautions for Use

Product use should be discontinued, and medical advice sought where appropriate, if irritation or rash occurs, or if the condition worsens or does not improve within 7 days.

When otitis externa is treated topically with preparations containing aminoglycosides, in patients who have a perforation of the tympanic membrane, there is an increased risk of drug induced deafness. It is therefore important to ensure that there is no perforation in such patients (see section Contraindications).

It is important to exclude chronic alternate diagnoses, including chronic otitis media, before treatment is commenced.

Treatment with corticosteroid/antibiotic combinations should not be continued for more than 7 days in the absence of any clinical improvement, since prolonged use may lead to occult extension of infections due to the masking effect of the steroid.

In children there is a theoretical risk that sufficient steroid may be absorbed to cause adrenal suppression, with prolonged use increasing this risk of adrenal suppression in children.

Prolonged use may also lead to skin sensitisation and the emergence of resistant organisms.

Due to potentially immature renal function in children toxicity may develop, thus caution is warranted when administering neomycin in this age group.

Aminoglycoside antibiotics may cause irreversible, partial or total deafness when given systemically or when applied topically to open wounds or damaged skin. This effect is dose related and is enhanced by renal or hepatic impairment. This possibility should be considered when high doses or prolonged treatment is given to small children.

Contains methyl and propyl hydroxybenzoates (E218 and E216) which may cause allergic reactions (possibly delayed).

Contains stearyl alcohol which may cause local skin reactions (e.g. contact dermatitis).

Interaction With Other Medicinal Products and Other Forms of Interaction

None known

Pregnancy and Lactation


There are no adequate data on the use of dexamethasone in pregnant women. Studies in animals have shown topical administration of corticosteroids to cause reproductive toxicity.

There is a risk of foetal ototoxicity if aminoglycoside antibiotics preparations are administrated during pregnancy.

Otomize is not recommended during pregnancy.


No reports describing the use of neomycin or dexamethasone during human lactation are available and the effects on the nursing infant from exposure to the drug in milk are unknown. Maternal use of topical preparations generally carries less risk than a systemically administered drug.

A risk to the breast-fed child cannot be excluded. A decision must be made whether to discontinue breast-feeding or to discontinue/abstain from Otomize therapy, taking into account the benefit of breast-feeding for the child and the benefit of therapy for the woman.

Effects on Ability to Drive and Use Machines

Unresolved ear problems could themselves affect driving ability.

Undesirable Effects

Some patients may experience a transient stinging or burning sensation for the first few days of treatment.

Skin sensitisation / hypersensitivity reactions (immediate and delayed) leading to irritation, burning, stinging, itching and dermatitis.

Reporting of suspected adverse reactions

Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at: www.mhra.gov.uk/yellowcard.


Overdosage by this route is extremely unlikely.

Pharmacological Properties

Pharmacodynamic Properties

Neomycin sulfate is an established antibiotic with a well characterised broad spectrum of activity. Dexamethasone is a well established topical anti-inflammatory steroid. Acetic acid functions to produce a low pH to assist in the control of bacterial infection.

Pharmacokinetic Properties

Otomize ear spray is applied topically to the external auditory meatus and acts locally.

The spray provides excellent distribution and coverage of the surface.

Preclinical Safety Data

No additional data of relevance.
