Sudden loss of vision is a rare but serious side effect associated with medications containing sildenafil citrate, such as Sildigra. This side effect is referred to as non-arteritic anterior ischemic optic neuropathy (NAION). NAION is characterized by a sudden, painless loss of vision in one or both eyes and can be permanent. Rare Occurrence The incidence of NAION associated with sildenafil is rare, and it is difficult to establish a direct cause-and-effect relationship. Nonetheless, cases have been reported. Risk Factors Some individuals may be at a higher risk for NAION, including those with a history of certain medical conditions, such as cardiovascular disease, diabetes, hypertension, or optic nerve disorders. Prompt Medical Attention If you experience any sudden changes in vision, such as partial or complete loss of vision, while taking Sildigra 250 Mg or a similar medication, seek immediate medical attention. Early intervention may be critical in managing the condition. Preexisting Eye Conditions Individuals with preexisting eye conditions, such as retinitis pigmentosa, may also be at a higher risk of vision changes while taking sildenafil. Stop Medication If you experience vision changes while taking Sildigra 250 mg usage or a similar medication, stop using the medication and consult a healthcare provider promptly. It's essential to discuss any concerns or questions about potential side effects, including vision-related issues, with your healthcare provider before starting or while taking medications like Sildigra. Your healthcare provider can provide guidance based on your individual health profile and help you make informed decisions about the use of these medications. Additionally, regular eye check-ups and overall health assessments are important for maintaining good eye health while using medications like Sildigra.
