Recently, I am diagnosed having parkinson and taking their medicine as prescribed by the doctor. I am also suffering from erectile dysfunction and premature ejaculation for past one year.

My bp, sugar and lipid profiles are normal. I am not clear in mind to take or not to take. Please advise whether I can enjoy by taking above medicine. Please reply clearly with reason. Thanks.
