Yes, dry ejaculation is a very common and entirely harmless side effect of Urimax (tamsulosin). It occurs because the medication relaxes the muscle at the bladder neck, causing semen to flow backward into the bladder during climax rather than exiting. The wonderful news is that this condition is fully reversible. Once you stop taking the medication, your ejaculation will return to normal, typically within a few days. It causes no permanent harm and does not affect your physical pleasure. Please consult your prescribing doctor if this side effect is bothersome for you.
