How long does a bottle of Tyrvaya last?

Dry eyes are a common condition that can cause symptoms like stinging, burning, itching, redness, and a gritty sensation. These symptoms occur when your eyes don’t produce enough tears or when the quality of your tears is poor. Choosing the right eye drops depends on how severe your symptoms are, the underlying cause of your dry eye, and your individual needs.

Tyrvaya works by activating a pathway in the nose that is responsible for your own natural tear production. It is thought to work as an agonist by binding to the nicotinic acetylcholine (nACh) receptor. This binding activates the trigeminal parasympathetic pathway in the nose to increase basal tear production. Continue reading

Tyrvaya does not reduce inflammation, it targets the trigeminal parasympathetic pathway which stimulates the lacrimal functional unit – an integrated system consisting of the lacrimal glands, surface of the eye, goblet glands and meibomian glands, and the nerves that connect them – to improve the quality and quantity of tear film produced. The trigeminal parasympathetic pathway is accessible through the nose, which is why Tyrvaya is produced as a nasal spray. This allows effective treatment of dry eye without the burning and stinging often associated with eye drops. Continue reading
