It is a relatively normal phenomenon to have yellow urine after taking B vitamin tablets, because after taking B vitamins, they need to be excreted through urine, which will lead to a yellow color of urine, which is a relatively common phenomenon. When the B vitamin tablets are discontinued, the urine will gradually return to its normal color. For patients who have taken B vitamin tablets, if you find that the urine is yellow, you do not need to be particularly worried or nervous, and you do not need special treatment, until the vitamin is metabolized by the kidneys, the urine will gradually return to its normal color. Of course, some patients who still have yellow urine after stopping the use of B vitamin tablets need to undergo active examination to identify the specific cause of the disease and carry out active treatment for the cause.
