Common questions about Tyrvaya

How often can you use Tyrvaya?
Tyrvaya should be sprayed into each nostril twice a day (about every 12 hours) to treat the signs and symptoms of dry eye disease. Follow the special Instructions for Use included with your prescription to learn how to correctly spray Tyrvaya, or ask your healthcare provider.
How quickly does Tyrvaya work?
When used twice a day in each nostril, Tyrvaya nasal spray may start working as quickly as the first week to increase eye tear film production. In clinical studies, Tyrvaya increased tear production and relief of symptoms at 4 weeks, on average, in mild to severe dry eye disease.
Can you use Tyrvaya long term?
The recommended dose is one spray in each nostril twice daily (about every 12 hours). Only change your dose or stop treatment if directed by your doctor. Tyrvaya is a prescription nasal spray used to treat symptoms of dry eye disease.
What are the best eye drops for dry eyes?
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. Continue reading
Can dry eyes cause blurry vision? Which medications help?
Yes, dry eyes can cause blurry or fluctuating vision. This occurs because dry eye syndrome disrupts the tear film that coats the eye’s surface, leading to uneven light refraction and irregularities on the corneal surface. Meibomian gland dysfunction, which affects the oily layer of the tear film, is a major contributor to this problem. Continue reading
What is the mechanism of action of Tyrvaya?
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
How long does a bottle of Tyrvaya last?
A bottle of Tyrvaya will last 15 days. This is because it contains 60 sprays and the recommended dose is ONE spray into BOTH nostrils Twice daily. This means you will use 4 sprays per day in total which will last 15 days. Each prescription of Tyrvaya comes with 2 glass nasal spray bottles which will last you 30 days in total. Continue reading
Does Tyrvaya reduce inflammation?
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
