Duratia 90 mg contains dapoxetine 90 mg (a selective serotonin reuptake inhibitor used for premature ***** in some markets). Vision-related side effects are not among the most common effects, but some people may experience changes such as: Blurred vision Difficulty focusing Visual disturbances (unusual changes in how things appear) Eye discomfort or sensitivity to light (reported less commonly) If you experience sudden vision loss, severe eye pain, a major change in vision, or persistent visual symptoms, seek urgent medical attention. Also note: Dapoxetine is generally used only when prescribed, and the recommended dosing varies by country. A 90 mg dose is higher than commonly used approved strengths in many places, so it is important to confirm the product and dose with a healthcare professional. Vision symptoms can also come from other medicines, blood pressure changes, migraines, or eye conditions. If you tell me what vision change you noticed (blur, color changes, flashes, loss of vision, etc.) and when it started after taking Duratia, I can help you assess how concerning it may be.
