What You Need to Know Before You Apply
What is the purpose of this trial?
This study explores the use of melatonin in patients with diabetic retinopathy
Will I have to stop taking my current medications?

Is melatonin safe for human use?
Melatonin, including its prolonged-release form (Circadin), has been shown to be well tolerated in humans, with mild side effects like nausea, dizziness, restlessness, and headache reported in a small number of cases. It has been used safely in various conditions, including sleep disorders and diabetes-related complications.12345
How does the drug melatonin differ from other treatments for diabetic retinopathy?
Melatonin is unique in treating diabetic retinopathy because it targets abnormal melatonin regulation linked to sleep and circadian rhythm issues, which are associated with the condition. Unlike other treatments, it may help by improving melatonin levels, potentially reducing oxidative stress and inflammation, and downregulating harmful proteins like VEGF, which are involved in the progression of diabetic retinopathy.36789
