Sildenafil can lead to slight damage in vision and in some rare cases painful erection. However, it is significant to emphasize that these side impacts do not affect every user. In fact, it's only a small percentage of users who actually experience these effects so don't be afraid to try the drug. Also, these effects are also temporary. They should go away after a few periods. If for any reason the side effects continue for hours after using Canforce, you should contact your physician for more information.
