Optamont (Olopatadine)

• Olopatadine acts on ocular allergic pathways to relieve inflammation and itching.
• Allergic conjunctivitis: reduces redness, swelling and itching in the conjunctiva.
• Seasonal allergic conjunctivitis: provides rapid relief of eye symptoms triggered by seasonal allergens.
• Ocular itching due to allergy: alleviates itching and discomfort caused by allergic reactions in the eye.

• Olopatadine selectively blocks histamine H1 receptors on conjunctival cells, preventing histamine‑mediated vasodilation and sensory nerve activation. In addition, it stabilizes mast cells, inhibiting the release of inflammatory mediators such as prostaglandins and leukotrienes. The drug’s high affinity for the H1 receptor ensures prolonged receptor occupancy, while mast‑cell stabilization curtails the early phase of the allergic cascade, leading to sustained symptom control after each dose.

Olopatadine may cause ocular and systemic adverse reactions, most of which are mild and transient.

Common Side Effects

• Transient burning or stinging sensation upon instillation.
• Temporary blurred vision.
• Mild eye irritation or redness.
• Headache.

Serious or Rare Side Effects

• Severe eye irritation or swelling of the eyelids.
• Allergic reaction such as rash or angioedema.
• Vision loss (very rare).
• Anaphylaxis (extremely rare).

• Before using Optamont, consider the following precautions to ensure safe and effective treatment.
• Allergy: Do not use if you are hypersensitive to olopatadine or any excipients.
• Contact lenses: Remove contact lenses before application and wait several minutes before reinserting.
• Ocular infection: Avoid use in eyes with active infection unless directed by an eye‑care professional.
• Systemic disease: Consult a physician if you have severe asthma or other systemic allergic conditions.
• Store at room temperature: Keep the bottle in its original packaging, protect from moisture and direct sunlight.

Olopatadine can interact with other ocular or systemic medications; awareness of these interactions helps minimize risk.

Major Interactions (Avoid)

• Concurrent use with other ophthalmic antihistamines may increase local irritation.
• Combination with ophthalmic anesthetic agents can potentiate corneal toxicity.

Moderate Interactions (Monitor Closely)

• Systemic antihistamines may enhance sedative effects, though rare with topical use.
• Beta‑blocker eye drops may have additive ocular hypotensive effects.
• Certain contact lens cleaning solutions may affect drug stability.
