What is Optihist Plus eye drop

Optihist Plus eye drops are a prescription medication used to relieve redness, itching, watering, and irritation caused by Allergic Conjunctivitis (Pink Eye) and minor eye irritations. The medication includes FDA-approved active salts Chlorpheniramine Maleate (0.03% w/v), Sodium Chloride (0.05% w/v), Boric Acid (1.25% w/v), and Tetrahydrozoline (0.01% w/v).

Chlorpheniramine is an antihistamine (H1 receptor blocker), and Tetrahydrozoline is a sympathomimetic decongestant or vasoconstrictor. On the other hand, Boric Acid acts as a mild antiseptic and buffering agent, and Sodium Chloride helps maintain moisture content. Entod Pharmaceuticals Ltd manufactures this combination eye drop in a GMP-compliant facility.

Chlorpheniramine works by blocking histamine (allergy-causing chemical) to reduce itching and swelling, while Tetrahydrozoline constricts blood vessels to decrease redness. Boric Acid and Sodium Chloride soothe irritation and maintain eye pH balance. These drops are mainly used for allergic eye symptoms, dust or pollen exposure, and mild conjunctival congestion.

The usually recommended dosage is 1–2 drops in the affected eye(s) twice daily, or as directed by an eye specialist. In case of overdose or excessive use, rinse eyes with clean water and seek medical guidance if irritation persists. If a dose is missed, apply it when remembered unless it is almost time for the next dose.

Possible side effects of these eye drops include mild burning, stinging, dryness, or blurred vision. Obtain medical help if severe pain, persistent redness, vision changes, or allergic reactions occur.

Avoid using Optihist Plus in Narrow-angle Glaucoma unless advised. Store the bottle tightly closed below 25°C, away from light.

What are the benefits of using Optihist Plus eye drop

Optihist Plus eye drop combines Chlorpheniramine Maleate, Sodium Chloride, Boric Acid, and Tetrahydrozoline to treat eye allergy symptoms. Chlorpheniramine is an antihistamine that inhibits histamine release, thus relieving itching and watering.

Tetrahydrozoline is a vasoconstrictor that narrows enlarged blood vessels, reducing redness. Sodium chloride and boric acid act as soothing and cleansing agents, maintaining eye comfort and proper pH balance.

This anti-allergic eye medication provides the following benefits when used as suggested by an eye doctor:

• Reduces eye itching and discomfort due to Pink Eye caused by allergies
• Minimizes redness rapidly
• Controls watering and swelling
• Provides a calming and cooling sensation
• Helps maintain eye moisture balance
