What Causes White Oily Molecules In Urine Inspite Of Being On Co-Terbinafine

Hello Dr. Andrew, I had some hair patches at the back of my scalp and started taking co-terbinafine based on my doctor's prescription and I have 2 weeks to go to finish the remaining 14 tablets. However I just observed some minute white oily kind of molecules in my urine this morning and I was curious to know if it is a side effect as a result of taking the medication.

Thanks for the help.
