Optivar review

Optivar is available as eye drops and is used to treat allergic pink eye. Under the brand names Astelin and Astepro, it is an antihistamine that is available as a nasal spray and is useful in treating hay pyrexia.

This antihistamine, as many others, blocks histamines from causing allergic reactions in the patient's body. It is applied directly to the areas affected by allergies, allowing quick relief. When used as a nasal decongestant, it does not lead to rebound congestion as it does not work like a topical vasoconstrictor.

Astelin is used for treating symptoms of seasonal allergic rhinitis like rhinorrhea, nasal pruritus and sneezing for both adults and children 5 years and above. It is also used to treat vasomotor rhinitis symptoms which include nasal congestion and postnasal drip for adults and children 12 years and older.

The brand name Astelin is the original formulation of Optivar used for treating both allergic and vasomotor rhinitis symptoms while Astepro is the newer formulation designed to treat only seasonal allergic rhinitis but is less bitter in taste and causes less discomfort than Astelin.

Optivaron is an eye solution prescribed for treating eye allergies and is used to alleviate swelling, redness and itchiness experienced with these kinds of allergies. It works in as quickly as three minutes and lasts as long as eight hours.

Before applying Optivar nasal spray for the first time, prime the container by squeezing the pump 4 times until a fine mist forms. If unused for 3 or more days, reprime the pump by squeezing twice or until a fine mist is achieved. Dosage is determined by your healthcare professional, so follow the prescription carefully. Tilt your head forward, and then sniff gently as you squeeze the spray bottle. Repeat as directed.

To use the eye drops, wash your hands first and do not touch the tip of the nozzle. Remove contact lenses before applying this medicament, and wait 10 minutes after application of eye drops before replacing the lenses as these may hinder the absorption of the medicament. Tilt your head back and pull your lower eyelid gently. Place the dropper directly over your eye and put one drop over each eye. Close your eyes and look down for a minute or two, then apply gentle pressure on your eyes with your fingertips. Do not blink or rub vigorously. Take as often as directed by your healthcare professional.

Remember that Astelin can cause drowsiness and can interfere with work, so be careful when performing dangerous tasks. Other common side effects include bitter tastes, cephalalgias, inflammation of nasal passages and sometimes bleeding. Those using Astelin to treat vasomotor rhinitis may also experience sinusitis.

Optivar eye drops may cause a stinging or burning sensation in your eyes for 1 to 2 minutes after application. Your vision may be blurred temporarily and you may also experience a bitter taste in your mouth. If any of these side effects persist, consult with your healthcare professional.

Notify your healthcare professional if you have previously experienced allergic reactions to Optivar or any other medicament.

Refrain from alcohol consumption while on Optivar treatment as this may intensify the drowsiness felt. Your dose may also have to be adjusted if you have any kidney conditions.
