Effectiveness

How Opcon-A Affects PatientsNaphazoline is a drug that can help reduce nasal or eye congestion by narrowing the blood vessels at the site of administration.
How Opcon-A works in the bodyNaphazoline is a drug that decreases congestion by narrowing the blood vessels in the area it is applied. It does this by releasing a chemical called norepinephrine that binds to receptors in the blood vessels and causes them to constrict. It can also cause rebound widening after the initial narrowing, and can lead to rhinitis medicamentosa if used for too long.

When to interrupt dosage

The suggested amount of Opcon-A is contingent upon the determined affliction, such as Eye Pain, Sinusitis and tetracycline. The measure fluctuates in agreement with the delivery system (e.g. Solution / drops or Liquid - Ophthalmic) specified in the table beneath.

Opcon-A for Red Eyes
I have been using Opcon A eye drops daily for over 15 years without incident until recently. Recently, I experienced a torn retina and had to have emergency laser surgery to repair it.

Opcon-A for Eye Itching
Although it may cause blurry vision for a few minutes, this is still an excellent product. It's very important not to rub your eyes, and these drops help with that immensely. I would highly recommend them to anyone dealing with allergies.

Opcon-A for Eye Itching
These are my go-to allergy drops. They work like a charm to stop the redness and itchiness I experience at night due to allergies. My doctor suggested storing them in the fridge, which really does help intensify the soothing effect of the cold drops.

Opcon-A for Eye Itching
Opcon-A was a great relief for my itchy, watery eyes. I would suggest cutting back on the number of drops used if you experience harsh side effects.

Opcon-A for Red Eyes
I've been using this product for about a year, and today I experienced something scary. My left pupil was very large, while my right pupil remained normal size. This gave me a headache, and made it difficult to see out of the dilated pupil. I went to the ER, but fortunately it fixed itself before long. However, I think the label should include a warning about this possible side-effect; it's not safe to drive after using these eye drops.
