What does the FDA approval of Tyrvaya nasal spray mean for dry eye treatment? Tyrvaya nasal spray was approved by the FDA on January 12, 2023,[1] for the treatment of dry eye disease. The approval is based on clinical trials that showed the effectiveness of the spray in improving tear production and reducing dry eye symptoms. How does Tyrvaya nasal spray work, and how does it compare to other dry eye treatments? Tyrvaya nasal spray is a recombinant human nerve growth factor product. According to a study published in the New England Journal of Medicine,[2] it works by stimulating the nerves in the lacrimal gland, which is responsible for producing tears. This results in increased tear secretion and reduced symptoms of dry eye. What are the benefits and potential side effects of using Tyrvaya nasal spray? The clinical trials for Tyrvaya nasal spray showed a significant improvement in dry eye symptoms, with patients experiencing a 40% increase in tear production compared to a placebo group.[3] However, as with any medication, there may be potential side effects, such as nasal congestion or eye irritation. When will Tyrvaya nasal spray be available, and what will it cost? The exact release date for Tyrvaya nasal spray has not been announced yet.
