Dilated pupils and blurry vision can be side effects of SNRI (serotonin-norepinephrine reuptake inhibitor) medications like desvenlafaxine. In most cases, pupil dilation and blurry vision caused by SNRIs are temporary and should resolve once the medication is discontinued or the dosage is adjusted. However, it's crucial to consult with your prescribing doctor or a healthcare professional to discuss your specific situation and determine the best course of action. They will be able to evaluate your symptoms, review your medical history, and provide personalized advice. If you are experiencing concerning or persistent side effects, it's important to seek medical attention promptly to ensure appropriate management and to rule out any other potential causes. Remember, it's always best to consult with a healthcare professional for accurate information and guidance regarding your specific condition and medication.
