Eye edema

Visual impairment

Foreign body sensation in eyes

Dysgeusia

Blurry vision

Hypersensitivity including signs and symptoms related to ocular allergy (e.g. conjunctivitis), angioedema (e.g. tongue edema) and allergic skin reactions (e.g. rash and contact allergy)

Contraindications

Hypersensivity to any component

Glaucoma, viral diseases of cornea & conjunctiva (epithelial herpes simplex keratitis, vaccinia, varicella), mycobacterial eye infection & fungal diseases of ocular structures

Cautions

Bacterial keratitis reported from inadvertent contamination of multiple dose ophthalmic solution Immunosuppression resulting from prolonged use of steroid use may result in secondary bacterial and fungal infections; steroids may also mask symptoms of infections and enhance existing ocular infections

Ocular hypertension and/or glaucoma reported with prolonged corticosteroid use

Corticosteroid and gentamicin use following cataract surgery may delay healing

Discontinue use if sensitivity reaction to gentamicin develops

Prolonged gentmicin use may result in fungal or bacterial superinfection

Pregnancy & Lactation

Pregnancy: C

Lactation: Unknown whether topical administration of corticosteroids could result in sufficient systemic absorption to produce detectable quantities in human milk; systemically administered corticosteroids appear in human milk and could suppress growth, interfere with endogenous corticosteroid production, or cause untoward effects

Pregnancy Categories

A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.

B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.

C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.

D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.

X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.

NA: Information not available.

Mechanism of Action

Prednisolone prevents/reduces irritation & swelling by suppressing normal immune response, decreasing inflammatory mediators and reverses capillary permeability

Gentamicin alters bacterial cell membrane integrity by binding to 30S and 50S ribosomal subunits, which in turn interferes with bacterial protein synthesis
