Now there will be another question that if taking the medicine for many years continuously, will there be any side effects on the body? Especially, many patients are concerned about having a sexual impotence but actually, there is only a 2% chance that would happen, which is very low. Will it affect the liver? Just a little and it’s not on a dangerous level. Hair transplant medicine does not accumulate in the liver. The body will drive it away by itself. Moreover, if you have the opportunity to have an annual physical examination and find that the liver function is normal, then there is no problem. You can continue taking the medication.
