Multidose vial contains 20 doses, and packaging includes 20 single-use syringes for administration. No refrigeration needed.

Relief That Delivers on Safety

Reliable efficacy in a single 0.8-mL dose.

There were no adverse reactions directly attributable to administration of Mometamax Single.

No clinically relevant treatment-related findings were noted in blood work and urinalysis.*

No ototoxicity was seen when dosed up to 5x the labeled dose every 2 weeks for 3 doses.

*Dogs were administered a series of 3 doses of Mometamax Single (0.8 mL) at 2-week intervals for the study.

Clean and dry the external ear canal. Shake the bottle vigorously for 15 seconds before each application.

Remove the cap from the bottle, and insert the syringe with the attached adapter by pressing it firmly into the top of the bottle using the attached syringe.

Invert the bottle and draw up 0.8 mL.  Leave adapter in the bottle.

Place the tip of the syringe at the entrance of the external ear canal and administer the 0.8-mL dose. The applied dose will flow into the ear canal.

After application, gently massage the base of the ear to ensure distribution of the product, and restrain the dog to minimize head shaking.  Use a new syringe for each affected ear.*

Disease Information

Otitis externa is inflammation of the external ear canal. It is a common problem that affects nearly 13% of dogs.11

  • Inflammation/reddening (erythema)
  • Scratching/itching (pruritus)
  • Head shaking
  • Heat
  • Pain
  • Foul smell (malodor) from the ear
  • Discharge (inflammatory exudate) present in and around the external ear canal
  • Hearing loss

Primary causes that incite inflammation:

  • Atopic dermatitis
  • Adverse food reaction
  • Hypothyroidism
  • Parasites
  • Masses or neoplasia

Most dogs develop otitis externa because of allergies to environmental substances.  The allergic reaction makes the ear itchy.  Dogs respond by scratching, which damages the lining of the ear canal. Yeast and bacteria then seize the opportunity and infect the skin.

Predisposing factors that increase the risk of otitis externa:

  • Conformation: Stenotic canals, pendulous pinnae, hair overgrowth
  • Moisture: Swimming, hot/humid climates

Chronic pathological changes can occur when the primary cause of otitis externa is not well controlled, further perpetuating the disease.
