Cetirizine Hydrochloride [Ophthalmic]: Brands, Price & Uses in Bangladesh
Cetirizine Hydrochloride [Ophthalmic] is an ophthalmic (eye) antihistamine solution.
About Cetirizine Hydrochloride [Ophthalmic]
Indications of Cetirizine Hydrochloride [Ophthalmic]
Cetirizine Hydrochloride [Ophthalmic] is an ophthalmic (eye) antihistamine solution. It is FDA-approved and established for a single, specific indication:
- Ocular itching due to allergic conjunctivitis — relief of eye itching caused by seasonal or perennial allergic conjunctivitis (e.g., itching triggered by pollen, dust, pet dander, or other airborne allergens).
This ophthalmic formulation of Cetirizine Hydrochloride [Ophthalmic] is intended only for the eyes and is distinct from oral cetirizine tablets/syrups, which are used for systemic allergic conditions such as allergic rhinitis or urticaria. Cetirizine Hydrochloride [Ophthalmic] is not indicated for, and does not treat, infectious (bacterial or viral) conjunctivitis, dry eye disease, or glaucoma.
Dosage & Administration of Cetirizine Hydrochloride [Ophthalmic]
Adult and Pediatric Dosing (2 years and older)
| Indication | Dose | Frequency |
|---|---|---|
| Ocular itching due to allergic conjunctivitis | Instill 1 drop in each affected eye | Twice daily, approximately 8 hours apart |
Administration Technique
- Wash hands before use.
- Tilt the head back, gently pull down the lower eyelid, and instill one drop into the pocket formed.
- Avoid letting the dropper tip touch the eye, eyelid, fingers, or any surface, to prevent contamination and injury.
- If using a multi-dose bottle, close the cap tightly after each use; if using single-use (unit-dose) containers, discard the container after one use — do not save for later use.
- Cetirizine Hydrochloride [Ophthalmic] should not be instilled while wearing contact lenses; remove lenses before instillation. Lenses may generally be reinserted about 10 minutes after the dose, per product instructions, once any associated eye redness has resolved.
- If using other topical eye medications, space them at least 5–10 minutes apart from Cetirizine Hydrochloride [Ophthalmic].
Side Effects of Cetirizine Hydrochloride [Ophthalmic]
Cetirizine Hydrochloride [Ophthalmic] is generally well tolerated. The most commonly reported adverse reactions (occurring in approximately 1–7% of patients in clinical trials) include:
- Ocular hyperemia (redness of the eye)
- Instillation-site pain or discomfort (mild transient stinging or burning upon administration)
- Reduced visual acuity (transient blurring)
These effects are usually mild and transient. Patients should contact their physician if any reaction is severe, persistent, or accompanied by significant pain, discharge, or vision changes.
Contraindications of Cetirizine Hydrochloride [Ophthalmic]
Cetirizine Hydrochloride [Ophthalmic] is contraindicated in patients with known hypersensitivity to cetirizine, hydroxyzine, or any component of the formulation.
Frequently Asked Questions about Cetirizine Hydrochloride [Ophthalmic]
What is Cetirizine Hydrochloride [Ophthalmic] eye drop used for?
Cetirizine Hydrochloride [Ophthalmic] is used to relieve itching in the eyes caused by allergic conjunctivitis, such as itching triggered by pollen, dust, or pet dander. It is not used for infections of the eye.
How is Cetirizine Hydrochloride [Ophthalmic] different from cetirizine tablets?
Cetirizine Hydrochloride [Ophthalmic] is a topical eye drop formulation applied directly to the eyes for local allergic itching, whereas oral cetirizine tablets/syrup are swallowed and act throughout the body for conditions like allergic rhinitis or hives. The two formulations are not interchangeable and this eye drop should not be swallowed.
How often should I use Cetirizine Hydrochloride [Ophthalmic]?
The usual dose is one drop in each affected eye, twice daily, about 8 hours apart. Do not use it more often than prescribed without consulting your physician.
Can I wear contact lenses while using Cetirizine Hydrochloride [Ophthalmic]?
No, remove contact lenses before instilling Cetirizine Hydrochloride [Ophthalmic], particularly if your eyes are red, and wait approximately 10 minutes after the dose before reinserting them, as advised on the product labeling.
Is Cetirizine Hydrochloride [Ophthalmic] safe during pregnancy or breastfeeding?
Data in pregnant and breastfeeding women are limited. Cetirizine Hydrochloride [Ophthalmic] should be used during pregnancy or lactation only if the potential benefit justifies the potential risk, and only after consulting a physician.
What should I do if my eye symptoms don't improve?
If your eye itching does not improve, worsens, or you notice significant redness, pain, discharge, or vision changes while using Cetirizine Hydrochloride [Ophthalmic], stop use and consult a physician promptly, as these symptoms could indicate a condition other than allergic conjunctivitis.
