Stacy Wiegman, PharmD, Pharmacy, answeredRiboflavin is generally safe to use. Most people can take riboflavin without having side effects. A common and mild side effect is yellow discoloration to urine. If you take a particularly high dose, you could feel itchy, burned or numb. Call your healthcare professional if you are concerned about your reaction to taking riboflavin.
