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 effective is Optilast?
Optilast is a very effective medicine that has been clinically proven to alleviate the symptoms brought upon by conjunctivitis, however, to purchase Optilast, it is required that you get a prescription, so if you feel like you need this medicine, you should consult your doctor and get that A-ok.
Optilast can be purchased online from most online pharmacies and it comes at a very affordable, the only pre-requisite that you need is an official prescription from a doctor. Once you have that, you can purchase a bottle; they come in at 8ml a container which is more than enough to help in your dire times.
Feel free to speak to medical professionals at Click Pharmacy if you need further advice on how to use the medication or if it is right for you.
What dose should I choose and for how long should I take it?
Before use, it is worth knowing that the treatment should not, under any circumstance, surpass a 6-week duration, as a clinical trial has determined that it is not healthy on the eye when this medicine is used for such a prolonged and continuous period.
For seasonal allergic conjunctivitis, the usual dosage in adults and children over the age of 4 is one drop in each eye twice daily that can be increased, if necessary to four times daily. If allergen exposure is anticipated, Optilast should be administered prophylactically, prior to the exposure.
For non-seasonal (perennial) allergic conjunctivitis, the usual dosage in adults and children 12 years and older is one drop in each eye twice daily that can be increased, if necessary to four times daily.
If symptoms have not improved or have even worsened after 48 hours of treatment, it is advised that you consult a doctor.
How should I take Optilast?
Before use, please wash your hand before using the eye as doing so reduces the risk of infection. Now for actually using the eye drops, one drop should put into each eye, this should be done twice a day when needed to relieve symptoms. If you find it necessary, you can increase the dosage, from using the drops twice a day to 4 times a day. As for hay fever (seasonal conjunctivitis), you can follow the same instructions as above, use the drops as instructed to help prevent your symptoms, if you know you are going to be exposed to pollen. As previously stated, your treatment should not last for over 6 weeks at most and if symptoms have not improved or have worsened after 48 hours, consult your doctor.
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.
What are the side effects of Optilast?
Like all medicine, Optilast does have several adverse effects; these include Slight irritation (burning, itching, watering) in the eyes after putting in Optilast. This should not last long. These effects are more common and tend to last a short amount of time if they even occur. A rather different side is you might get a bitter taste in your mouth. This should quickly disappear especially if you have a soft drink. 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.
What is the difference between Optilast, Rapitil eye drop, and Opatanol?
The main difference between Optilast and Rapitil eye drop is that while helping with the same issue, Rapitil won’t have an immediate effect, whereas Optilast does its job immediately.
The main difference between Optilast and Opatanol is that the latter can be taken from the age of 3 whereas Optilast can only be taken from the age of 4 years.
