Indications & Clinical Uses

Iridina Due is an ocular decongestant that acts on the conjunctival vasculature to relieve redness and irritation.

  • Conjunctival hyperemia: reduces visible eye redness caused by dilated blood vessels.
  • Minor ocular irritation: alleviates discomfort and transient redness from environmental factors.
  • Eye redness due to mild allergic or irritant exposure: provides short‑term visual comfort.

How It Works

  • Naphazoline Hydrochloride selectively stimulates alpha‑adrenergic receptors on the smooth muscle of conjunctival blood vessels. This activation causes vasoconstriction, decreasing blood flow to the ocular surface and thereby reducing the appearance of redness and swelling associated with conjunctival hyperemia.

Side Effects

Common Side Effects

  • Burning sensation: mild, transient feeling after instillation.
  • Stinging: brief discomfort on the ocular surface.
  • Temporary blurred vision: resolves within minutes.
  • Mild itching: occasional sensation of irritation.
  • Dryness: slight reduction in tear film.
  • Redness rebound after prolonged use: may reappear if used excessively.

Serious or Rare Side Effects

  • Severe ocular hypertension: marked increase in intra‑ocular pressure.
  • Corneal ulceration: rare but serious corneal damage.
  • Allergic reaction (angioedema): swelling of eyelids or surrounding tissue.
  • Irregular pupil dilation (mydriasis): abnormal pupil size.
  • Vision loss: extremely rare, requires immediate medical attention.
  • Systemic adrenergic effects: rapid heart rate or elevated blood pressure.

Precautions & Warnings

Before using Iridina Due, consider the following precautions.

  • Avoid prolonged use: may cause rebound redness and tachyphylaxis.
  • Do not use while wearing contact lenses: remove lenses before application.
  • Consult an eye specialist if you have glaucoma or ocular hypertension.
  • Avoid use in children under 2 years: safety not established.
  • Do not combine with other vasoconstrictive eye drops without professional advice.
  • Store at room temperature: keep in the original container, protect from light and moisture.

Avoid Interactions

Iridina Due may interact with other ophthalmic or systemic agents.

Major Interactions (Avoid)

  • Other ocular decongestants: additive vasoconstriction can increase risk of ischemia.
  • Monoamine oxidase inhibitors (MAOIs): potential systemic adrenergic stimulation.
  • Sympathomimetic agents: heightened cardiovascular effects.

Moderate Interactions (Monitor Closely)

  • Topical anesthetics: may increase corneal toxicity when used together.
  • Antihistamine eye drops: monitor for increased irritation.
  • Systemic antihypertensives: observe blood pressure for possible fluctuations.

Frequently Asked Questions

Iridina Due is an over‑the‑counter ophthalmic solution containing Naphazoline Hydrochloride. It is used to temporarily relieve eye redness and minor irritation caused by conjunctival hyperemia, environmental irritants, or mild allergic reactions.

Naphazoline Hydrochloride acts as a selective alpha‑adrenergic agonist. By stimulating alpha receptors on conjunctival blood vessels, it induces vasoconstriction, which reduces blood flow to the ocular surface and diminishes visible redness and swelling.

The specific dosing regimen is determined by the prescribing eye‑care professional. Typically, one drop is instilled in the affected eye(s) up to three times daily, but patients should follow the exact instructions provided by their clinician.

Safety data for Naphazoline Hydrochloride in pregnancy and lactation are limited. Women who are pregnant, planning to become pregnant, or breastfeeding should consult their healthcare provider before using Iridina Due to assess potential risks.

To place an order, submit an enquiry on the Iridina Due product page at gnhindia.com, specifying the required quantity. GNH India works with hospitals, pharmacies, and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details, and any necessary import documentation.

Iridina Due (Naphazoline) and alternatives such as tetrahydrozoline share the same alpha‑adrenergic mechanism. Naphazoline generally has a rapid onset of action and a slightly longer duration, but both carry similar risks of rebound redness with prolonged use. Choice often depends on clinician preference and patient response.

Iridina Due should be stored at room temperature, below 25 °C, in its original packaging. Keep the bottle tightly closed, protect it from direct sunlight and moisture, and discard any product that appears discolored or contains particles.

Iridina Due is applied as an eye drop. The patient tilts the head back, pulls down the lower eyelid to create a small pocket, and instills the prescribed number of drops. The eye should be closed gently for a few seconds to allow absorption, avoiding blinking or rubbing.

Serious risks, though rare, include severe ocular hypertension, corneal ulceration, and allergic reactions such as angioedema. If any sudden vision changes, intense pain, or swelling occur, the user should seek immediate medical attention.

Iridina Due should be avoided in individuals with known hypersensitivity to Naphazoline or any formulation component, in patients with narrow‑angle glaucoma, severe ocular hypertension, or in children under two years of age unless directed by a qualified eye‑care professional.
