Larmabak (Sodium Chloride)

Larmabak is an ophthalmic saline solution that acts on the ocular surface to restore normal tear‑film balance and provide irrigation.

• Dry eye syndrome: improves tear‑film stability and reduces discomfort.
• Ocular surface hydration: supplies moisture to the cornea and conjunctiva.
• Eye irrigation: helps remove debris, allergens, or chemicals from the eye.

• Sodium Chloride in Larmabak creates an isotonic environment on the ocular surface, matching the osmolarity of natural tears. This osmotic balance reduces hyperosmolar stress, dilutes irritants, and promotes a stable tear film, thereby supporting corneal and conjunctival health while facilitating gentle mechanical cleansing of the eye.

Larmabak is generally well tolerated, but some users may experience ocular reactions.

Common Side Effects

• Stinging or burning sensation upon instillation.
• Transient blurred vision that clears within minutes.
• Mild ocular redness or hyperemia.
• Temporary tearing or excess discharge.
• Sensation of foreign body in the eye.

Serious or Rare Side Effects

• Allergic reaction with swelling, itching, or rash around the eye.
• Severe eye pain or persistent irritation.
• Development of corneal ulceration or infection.
• Sudden loss of vision or visual disturbances.
• Persistent discharge indicating secondary infection.

When using Larmabak, consider the following safety measures.

• Hypersensitivity: discontinue if known allergy to sodium chloride or formulation components.
• Contamination: use only sterile, unopened vials; do not reuse single‑dose containers.
• Contact lenses: remove lenses before instillation and re‑insert after blinking.
• Persistent irritation: stop use and seek medical advice if symptoms continue.
• Children: keep out of reach and use only under supervision.
• Store at room temperature: keep in the original packaging, protect from moisture and direct sunlight.

Larmabak may interact with other ophthalmic products; monitor the following.

Major Interactions (Avoid)

• Preservative‑containing contact lens solutions: may cause incompatibility or ocular irritation.

Moderate Interactions (Monitor Closely)

• Topical antibiotics: saline may dilute concentration, affecting efficacy.
• Vasoconstrictive eye drops (e.g., naphazoline): monitor for altered ocular blood flow.
• Systemic medications causing dry eye (e.g., antihistamines): may reduce overall comfort.
• Other lubricating eye drops: stagger administration to avoid wash‑out effect.
