I have been taking Oleptal DT 300 mg tablets twice a day for the last 6 to 7 months. Since starting this medicine, my urine has become pale yellow and my lab report shows an RBC count between 10 and 20; can this medicine cause these side effects, and what should I do next?

Pale yellow urine is normal and shows you are well-hydrated. However, having red blood cells (RBCs 10-20) in your urine (hematuria) is not a typical side effect of Oleptal DT (oxcarbazepine). While rare kidney or blood-thinning side effects can occur, other conditions like a urinary tract infection (UTI) or kidney stones are more likely causes. What you should do next: 1. Do not stop taking Oleptal DT abruptly, as this can trigger seizures. 2. Consult your doctor or a urologist promptly. They will likely order a repeat urine test, a complete blood count, and kidney function tests to determine the exact cause safely.
