Malegra DXT Plus contains Sildenafil Citrate (100 mg) and Duloxetine (60 mg). The visual disturbances experienced by some users are mainly caused by Sildenafil Citrate and occur due to its effects on the PDE5 enzyme and blood flow regulation. Why Malegra DXT Plus Causes Visual Disturbances Inhibition of PDE6 in the Retina Sildenafil not only blocks PDE5 (which improves erections) but also partially affects PDE6, an enzyme found in the retina. This can cause color vision changes, especially a blue-tinted vision or difficulty distinguishing between blue and green. Changes in Blood Flow to the Optic Nerve Sildenafil can reduce blood supply to the optic nerve, leading to temporary blurriness or vision loss in rare cases. In extreme cases, it may contribute to non-arteritic anterior ischemic optic neuropathy (NAION), a rare but serious condition that can cause sudden vision loss. Increased Intraocular Pressure (IOP) Some users may experience temporary increases in eye pressure, leading to eye pain or discomfort. This is more common in individuals with pre-existing glaucoma or other eye conditions. Dizziness and Light Sensitivity (Duloxetine Effect) Duloxetine, the antidepressant in Malegra DXT Plus, may cause dizziness, light sensitivity, and visual focus issues as part of its central nervous system effects. Who is at Higher Risk? People with a history of eye diseases, such as glaucoma or retinal disorders. Those with high blood pressure, diabetes, or heart conditions (which can affect blood flow to the optic nerve). Users taking other PDE5 inhibitors or medications that affect vision.
