Malegra FXT can cause vision changes in some people, mainly because it contains sildenafil, which is a PDE5 inhibitor. Sildenafil may temporarily affect visual perception by influencing an enzyme involved in the eye’s light-processing system. Possible vision-related effects include: Blurred vision Increased sensitivity to light A blue or tinted appearance to vision (sometimes reported as a bluish hue) Difficulty distinguishing certain colors Temporary changes in visual clarity These effects are usually mild and short-lived, but sudden vision loss, severe eye pain, or a major change in eyesight requires urgent medical attention. Malegra FXT also contains fluoxetine, which can rarely be associated with eye-related problems such as increased risk of angle-closure glaucoma in susceptible individuals. Avoid taking Malegra FXT without medical guidance if you have a history of eye conditions, especially retinal disorders, glaucoma, or previous vision problems, or if you take medicines that may interact with it. If you notice new or persistent vision changes after taking it, consult a healthcare professional before using another dose.
