What is Optilast

Optilast Eye Drops helps combat seasonal allergic conjunctivitis or allergic (perennial) conjunctivitis that is not seasonal. These reactions occur as a result of an allergy-caused inflammation of the eye's outermost layer, which corresponds to hay fever.

How does Optilast work?

Optilast does its magic thanks to its main active ingredient, azelastine hydrochloride, which is a type of medicine known as an antihistamine. Azelastine works its wonders by preventing the actions of histamine; histamine is a substance produced by the body when it identifies and reacts to foreign material, such a pet fur or pollen, among others (which in itself are called allergens). Histamine causes a volatile chain reaction that results in allergic symptoms. Whereas a result, it causes inflammation and symptoms such as itchy, red and watery eyes. When Azelastine is administered into the eyes, it blocks the histamine receptors in the eyes, and so stops this chain reaction, and a result should start to relieve the eye symptoms within 15 to 30 minutes.

How should I use Optilast?

Before use, please wash your hands to reduce the risk of infection. Put one drop into each eye twice daily or when needed to relieve symptoms. If necessary, you can increase the dosage to 4 times a day. As for hay fever (seasonal conjunctivitis), you can follow the same instructions as above. Your treatment should not last longer than 6 weeks. If your symptoms have not improved or have worsened after 48 hours, consult your doctor.

What are the side effects of Optilast? 

Like all medicines, Optilast can cause several adverse effects, such as slight eye irritation (burning, itching, watering). This should not last long. Another side effect presents as a bitter taste in your mouth. This should quickly disappear, especially if you drink some water. Swelling or pressure of the eye may occur; these adverse effects may come due to an allergic reaction. If any of the more severe side effects do happen, please go to a doctor immediately.

When shouldn’t I take Optilast?

Do not take Optilast if you are allergic to any of the active or inactive ingredients, as these may exacerbate the situation you’re trying to improve by a rather large margin. You should not give this medicine to anyone under the age of 4 years. Make sure your doctor knows if you are pregnant or breastfeeding, as there is a small possibility that Azelastine ma pass to the bloodstream and, thus, may negatively affect the baby. Consult your doctor beforehand. Do not use the eye drops if the bottle has been opened for more than 4 weeks, as it could have been contaminated with dirt or germs that could cause even more severe eye infections.
