In rare cases, loss of strength, general muscle weakness, vision disturbances, or dizziness may occur within hours to weeks following treatment. If such symptoms develop, patients should refrain from driving, operating heavy machinery, or engaging in other potentially hazardous activities until symptoms resolve.
Other potential side effects include dry mouth, discomfort or pain at the treatment site, fatigue, headaches, neck pain, and various eye-related issues such as double vision, blurred vision, decreased eyesight, drooping eyelids or eyebrows, eyelid swelling, and dry eyes.
