While using Ivabradine, you may experience bright visions for brief moments (called luminous visual phenomena). This may be accompanied by colored flashes, multiple images, bright circles (halo), etc. These symptoms mostly occur when you start treatment with Ivabradine and will resolve in the first two months. Hence you are advised not to discontinue the medicine if you experience any visual symptoms within the first two months and inform your doctor if they persist beyond two months. Ivabradine has to be stopped if there is no improvement in symptoms within 3 months of starting this medicine. Inform your doctor if this applies to you. The dose of Ivabradine has to be reduced if your heart rate falls below 50 beats per minute. If it remains low and does not improve after decreasing the dose, the medicine may have to be discontinued.
