Q. I had testicular cancer some years ago. I am now on blood-thinning tablets. Can I still use Ciavor to get an erection?
A. Hypogonadism is a condition in which the body doesn't produce enough testosterone. The cause in this case is possible side-effects of radiation therapy for prostate cancer. The symptoms may include sexual dysfunction, including diminished erectile function or a decrease in the volume of semen produced.
Nebido is a testosterone used to increase libido. It has a positive effect on erectile function in cases of testosterone deficiency caused by hypogonadism.
At the start of treatment, you require monitoring of your blood testosterone levels to monitor response to the replacement and to establish an injection interval, commonly between 10 to 14 weeks.
The standard therapy for treatment of erectile dysfunction are oral phosphodiesterase type 5-inhibitors (PDE5i).
Ciavor is used to treat erectile dysfunction, has a long duration of action - up to 36 hours in some patients - and has been demonstrated to be effective for most causes of erectile dysfunction.
The combination of PDE5i and testosterone may be indicated in this case of hypogonadal disorder.
Xarelto, which is Rivaroxaban, blocks the activity of certain clotting substances in the blood and is used as prevention or treatment for some serious medical conditions.
It may be necessary to get an opinion of a physician to evaluate your risk, continued indication for blood-thinning agents and possible drug interactions with PDE5i inhibitors.
A physician may examine risk factors and draw blood samples to rule out diseases, medications, excessive alcohol and nicotine consumption and mental health disorders. It is recommended you have an evaluation with your urologist.
