Have had several episodes of blood in semen since beginning Pradaxa several months ago (for atrial fibrillation. No blood visible in urine and urine test confirms. Is it likely that Pradaxa is the cause of the hematospermia? Is this anything to worry about?
Good day, and thank you for being with Chat Doctor !!! Yes Prada would make you at risk for bleeding in the seminal vesicle especially after sexual activity or rigorous ejaculation. It is also better to have your prostate checked to rule out prostate pathology that may cause the blood in the semen.  Prostate should be checked by serum PSA, ultrasound and a digital rectal examination by a urologist. Majority of blood in the semen are self limiting and goes away on its own. You might need to abstain for 1-2 weeks from ejaculation and everything will become normal.
