Paristin Eye Drop

Paristin Eye Drop is a sulfacetamide ophthalmic antibiotic used to treat certain bacterial eye infections. Each eye drop contains sulfacetamide in the strength listed on the label, and it belongs to the sulfonamide class of medicines. Paristin Eye Drop is commonly prescribed for infections such as conjunctivitis and other surface eye infections caused by susceptible bacteria.

How it works: Sulfacetamide works by stopping bacteria from making substances they need to grow and multiply. As an eye drop, Paristin Eye Drop delivers the antibiotic right to the infected eye surface, helping reduce the bacterial load where it is needed most.

Paristin Eye Drop is the exact labeled strength in eye-drop form, so it is meant for local treatment directly on the eye rather than a lower-dose oral product or another form. Because there are no other strengths or forms listed for this brand, your doctor will choose this product when the labeled concentration is appropriate for the infection being treated and for the amount of medicine needed in the eye.

• Bacterial conjunctivitis
• Surface eye infections caused by susceptible bacteria
• Eye infection treatment as prescribed by a doctor
• Reduction of redness and discharge from bacterial eye infection

• Wash your hands before using Paristin Eye Drop.
• Tilt your head back, pull down the lower eyelid, and place the prescribed number of drops into the eye.
• Do not touch the dropper tip to your eye, fingers, or any surface.
• Close your eye gently after instilling the drop; do not blink hard or rub the eye.
• If you use other eye medicines, wait at least 5 to 10 minutes between products unless your doctor tells you otherwise.
• Use it exactly as prescribed and finish the full course even if your eye starts to feel better.

Paristin Eye Drop provides sulfacetamide in the strength printed on the label, delivered as an eye drop for direct use in the affected eye. How often it is used can vary by the infection and your doctor’s instructions; there is no one fixed maximum per day for every patient, so the prescriber decides the schedule and duration based on your condition and response.

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

Common side effects of Sulfacetamide may include:

• Mild eye stinging or burning after instillation
• Temporary blurred vision after the drop
• Eye irritation or redness
• Watery eyes
• Itching or discomfort in the eye
• Unpleasant taste in the mouth after use

• Do not use Paristin Eye Drop if you have a known sulfonamide allergy unless a doctor specifically says it is safe.
• This medicine is for the eye only; do not swallow it or use it in the ear or on the skin.
• Contact lens wearers may need to avoid lenses during active eye infection and while using the drops, depending on the doctor’s advice.
• Temporary blurred vision can happen after dosing, so wait until your vision is clear before driving or using machinery.
• Tell your doctor if you are pregnant, breastfeeding, or have a history of severe drug allergies.
• If symptoms worsen or do not improve as expected, medical reassessment may be needed because not all eye redness is bacterial.
• Use caution if you are using other prescription eye products, since they may need to be spaced apart.

• Other ophthalmic medicines or eye drops, which may need to be separated in time
• Other sulfonamide medicines, because allergy risk may overlap
• Medications that suppress the immune system may affect infection control
• Topical eye products containing similar preservatives or antibiotics may increase irritation

Store Paristin Eye Drop at room temperature, tightly closed, and protect it from contamination, heat, and direct light.
