Fildena 150 mg contains sildenafil citrate, which is used to treat erectile dysfunction by increasing blood flow. However, men with certain retinal conditions should avoid using Fildena 150 mg due to potential risks.

Sildenafil can affect the blood flow to the optic nerve and retina, which may worsen existing eye problems. Men with a history of non-arteritic anterior ischemic optic neuropathy (NAION)—a condition causing sudden vision loss due to reduced blood flow to the optic nerve—should avoid sildenafil. Using Fildena may increase the risk of NAION recurrence or exacerbate retinal damage.

Additionally, men with retinitis pigmentosa or other inherited retinal degenerations should use caution, as sildenafil might affect retinal function or interact adversely with their condition.

If you have any history of vision loss, blurred vision, or eye diseases, it's crucial to inform your healthcare provider before taking Fildena 150 mg. Also, if you experience sudden vision changes while using the medication, stop taking it immediately and seek emergency medical care.

In summary, Fildena 150 mg should be avoided or used only under strict medical supervision in men with retinal issues to prevent potential vision complications. Always consult an eye specialist or healthcare provider before starting this medication if you have retinal concerns.
