Filitra 10 mg, containing sildenafil citrate, is primarily used to treat erectile dysfunction by increasing blood flow to the penis. While it is generally well-tolerated, it can sometimes affect vision. Some users report temporary visual disturbances such as blurred vision, increased sensitivity to light (photophobia), or a slight blue tint to their vision. These effects are usually mild and short-lived, resolving as the medication wears off. Rarely, serious eye complications like non-arteritic anterior ischemic optic neuropathy (NAION), which can cause sudden vision loss, have been reported. Patients with pre-existing eye conditions, such as retinitis pigmentosa or severe cardiovascular problems, should consult a doctor before using Filitra 10 and seek immediate medical attention if they experience sudden vision changes. Regular eye monitoring may be advised for those at higher risk.
