How to Use

Usage Instructions

• Prescription Required: Federal law limits the use of this drug to licensed veterinarians or those acting on their orders. Do not give this medication to your pet without proper authorization from a vet.
• Wash Hands Before Use: Thoroughly wash your hands before handling the bottle or applying drops to prevent introducing additional contaminants into your pet's already-infected eye.
• Gently Shake Before Use: Gently shake the bottle before each application to ensure the medication is properly mixed for consistent and effective dosing.
• Instill 1 to 2 Drops per Eye: Apply 1 to 2 drops directly into the conjunctival sac of the affected eye, 2 to 4 times a day, or as your vet has instructed.
• Increase Frequency in Severe Infections: In more severe bacterial eye infections, your veterinarian may advise applying up to 2 drops every hour; always follow their specific guidance.
• Do Not Touch the Dropper Tip: Keep the dropper tip away from the eye, eyelid, hands, or any other surface. Touching the tip to anything can introduce harmful bacteria directly into the eye.

Additional Information

Precautions

• Confirm Antibiotic Susceptibility First: Before beginning treatment, antibiotic susceptibility of the infecting organism should be determined to confirm that gentamicin will be effective against the specific bacteria involved.
• Not for Viral or Fungal Eye Infections: Do not use this antibiotic solution if your pet has a viral or fungal eye infection, as it will not treat these conditions and may worsen the situation.
• Avoid Use with Other Eye Medications: Do not use other eye medications simultaneously with gentamicin sulfate unless specifically directed by your veterinarian, as interactions may reduce effectiveness.
• Not for Injection: This solution is for topical ophthalmic use only and must never be injected subconjunctivally or introduced into the anterior chamber of the eye.
• Inform Vet of Pregnancy or Lactation: Inform the vet if your pet is nursing or pregnant before beginning this treatment, as the safety of gentamicin in these situations needs to be evaluated first.
• Keep Out of Reach: Always store this medication in a place inaccessible to children and other pets to prevent accidental ingestion or misuse.

Possible Side Effects

• Temporary Eye Burning or Stinging: Some pets may experience mild, temporary burning or stinging immediately after application; this generally does not require stopping the medication.
• Eye Irritation and Redness: Local irritation, itching, redness, or sensitivity to light may occasionally occur; continue use and speak with your veterinarian if these reactions seem bothersome or persistent.
• Eyelid Swelling or Itching: Mild eyelid itching or swelling has been reported in some animals after use; notify your vet if this occurs and seems disproportionate or worsening.
• Overgrowth of Non-Susceptible Organisms: Prolonged use of topical antibiotics can allow fungi or non-susceptible bacteria to overgrow in the eye; discontinue use and seek veterinary guidance immediately if this occurs.
• Hypersensitivity Reactions: If your pet shows signs of an allergic reaction or hypersensitivity to any component of this solution, discontinue use immediately and consult your veterinarian.

Storage Information

• Store at Controlled Room Temperature: Store the solution at 20°C - 25°C (68°F - 77°F) in line with USP Controlled Room Temperature guidelines to keep it sterile and fully effective.
• Avoid Excessive Heat: Do not expose the bottle to temperatures above 40°C (104°F), as excessive heat can degrade the solution and compromise its sterility and efficacy.

Ans: This antibiotic eye drop is used to treat bacterial eye infections including keratitis, keratoconjunctivitis, corneal ulcers, blepharitis, blepharoconjunctivitis, conjunctivitis, acute meibomianitis, and dacryocystitis caused by bacteria susceptible to gentamicin in dogs and cats.

Q2: How does Gentamicin Sulfate Ophthalmic Solution work to clear eye infections in pets?

Q3: Can I use this Gentamicin eye solution if my cat or dog has a fungal eye infection?
