Netilmicina is an antibiotic that eliminates the bacteria that cause infections.

Dexametasona is a corticosteroid that reduces inflammation and redness.

This medication is used in adults to reduce inflammation and eliminate bacteria in the eyes in cases of infection or when bacteria may infect the eye, even after surgery.

You should consult a doctor if your condition worsens or does not improve at the end of treatment.

Advertencias y precauciones

Consult your doctor or pharmacist before starting to use this medication.

Consult your doctor if you experience swelling and weight gain around the trunk and face, as these are usually the first signs of a condition called Cushing's syndrome. Discontinuing long-term or intensive treatment with this medication may lead to suppression of adrenal gland function. Consult your doctor before stopping treatment on your own. These risks are especially important in children and patients treated with a medication called ritonavir or cobicistat.

Use with caution in patients whose cornea (the transparent layer at the front of the eye) may be compromised and in cases where the patient uses other eye medications containing phosphates (see section 4).

Patients without pre-existing corneal damage do not appear to be at risk.

Contact your doctor if you experience blurred vision or other visual disturbances.
