[|Human|] My husband has has prostrate cancer and surgery. He is unable to perform sexually. He has tried Viagra but ran out of them. We visited an adult store and purchased one pill named Miracle zen for male sexual performance . The problem is he is taking allopurinol, lisinopril, and lovastatin and is little concern about using this male enhancement pill.
[|AI|]  Good Day, and thank you for being with Chat Doctor ! I am just concerned that most OTC male enhancement vitamin or supplements contains testosterone and its derivatives and may have a very bad effect on his prostate cancer. I would caution you with the use of such products. Better stick with sildenafil. I hope I have succeeded in providing the information you were looking for. Please feel free to write back to me for any further clarifications at: http://www.ChatDoctor .com/doctors/ Chat Doctor.  Best wishes
