Report your persistent side effects to drug regulatory agencies

Global health & drug regulatory agencies

If you are experiencing an adverse reaction, either while ON the drug or AFTER quitting, PLEASE REPORT IT TO THE APPROPRIATE AGENCIES.

It is only by submitting complaints (either directly or through your doctor) that we can generate awareness about men suffering from persistent side effects. The more men that submit reports of persistent side effects, the more the Agencies will take notice of the problem, and are thus more likely to investigate the drug and hopefully make prescription, labeling or other regulatory changes regarding usage.

If you have not submitted an adverse reaction report yet, please do so — today.
