Russian hackers leaked documents last week showing Farah was suspected of doping in 2015 before being cleared by the International Association of Athletics Federations (IAAF) in 2016, British media reported.
"I am sick of repeating myself and you guys just making something out of nothing," Farah told reporters on Sunday.
"I work hard at what I do and I just carry on enjoying what I do, and it comes as a little distraction...
"I said I will never fail a drugs test. That is who I am. I believe in clean sports and I just have to enjoy what I do, keep smiling. And let you guys do what you do.
"There's no secrets to what I do. My life is not as easy as people think, it is hard work. I wish you guys would understand it a bit more and write down the facts. I do what I do, keep smiling. I love you all."
Farah has fielded doping allegations repeatedly and the issue re-appeared in April after a doctor said that he injected a legal dose of a controversial substance prior to the 2014 London Marathon but it was not adequately recorded.
The long-distance runner said he would not be racing in the 1 500m event in Monaco and will instead go to an altitude training camp in Font Romeu, France to prepare for next month's world championships.
