Locula 10% Eye Drop

Locula 10% Eye Drop is a prescription eye medicine that contains sulfacetamide 10% in each dose, formulated for use directly in the eye. It belongs to the sulfonamide class of antibiotics and is used to treat certain bacterial eye infections such as conjunctivitis and other susceptible infections of the eyelids or eye surface. Locula 10% Eye Drop is intended for eye use only and should be used exactly as directed by a clinician.

How it works: Sulfacetamide stops susceptible bacteria from making the folic acid they need to grow and multiply. When used as Locula 10% Eye Drop, it acts right on the eye surface to help clear the bacterial infection.

Locula 10% Eye Drop is one of the lower-strength options in the Locula range, with Locula 20% 10 mL Eye Drop and Locula 30% 10 mL Eye Drop providing stronger sulfacetamide concentrations. This 10% eye drop may be chosen when a prescriber wants a gentler starting point, when infection severity does not call for a higher strength, or when the eye is particularly sensitive. Because it is the 10% strength, it may be easier to tolerate for some patients than the stronger sister products, but the right choice depends on the infection and the prescriber’s assessment.

• Bacterial conjunctivitis
• Susceptible eyelid infections
• Eye-surface bacterial infections
• Treatment of bacterial growth in the eye as prescribed

• Wash your hands before using Locula 10% Eye Drop.
• Tilt your head back, pull down the lower eyelid, and place the prescribed number of drops into the pocket of the eye.
• Do not let the dropper tip touch your eye, fingers, or any surface.
• Close your eye gently for 1 to 2 minutes after dosing; do not blink hard or rub the eye.
• If you wear contact lenses, remove them before using the drops and wait to put them back in unless your doctor says otherwise.
• Use the drops at the times your doctor prescribed and finish the full course even if symptoms improve.

Each dose of Locula 10% Eye Drop delivers sulfacetamide 10% directly to the eye, and the exact number of drops per dose is determined by your doctor. It may be used several times a day depending on the infection, but the maximum daily amount and treatment length should be set by the prescriber for your specific case. Do not change the dose or frequency on your own, especially compared with the stronger Locula 20% and Locula 30% eye drops.

Do not change your dose or stop the medicine without speaking to your doctor.

Common side effects of Sulfacetamide may include:

• Temporary stinging or burning after instilling the drops
• Eye redness or irritation
• Blurred vision right after dosing
• Itching or mild eye discomfort
• Teariness or dryness
• Unpleasant taste in the mouth after use

• Do not use Locula 10% Eye Drop if you have a known sulfonamide allergy unless a doctor specifically tells you to.
• This medicine is for the eye only; do not swallow it or inject it.
• Contact lens wear may worsen irritation, so ask your doctor when to remove and replace lenses.
• If your vision is blurred after dosing, do not drive or do tasks that need clear sight until it clears.
• Use extra caution if you have a history of severe allergies, asthma, or prior reactions to sulfa medicines.
• Tell your doctor if symptoms do not start improving or if they get worse after several days.
• Use only the prescribed amount; higher-strength Locula eye drops are not interchangeable without medical advice.

• Other eye medicines or drops, which may need to be spaced apart
• Other sulfonamide medicines, due to possible allergy or side effect overlap
• Warfarin or other blood thinners, if your clinician is monitoring for sulfonamide-related interactions
• Methotrexate, which may increase the risk of side effects in some patients

Store Locula 10% Eye Drop at room temperature, tightly closed, and keep the bottle clean and protected from contamination.
