Alexei Navalny is in poor health.
His spokeswoman Kira Jarmysch wrote on Twitter that he was again unable to attend a court hearing because he was too ill for it.
Supporters and family members of the imprisoned Kremlin opponent are concerned about the 46-year-old's health.
A few days ago, Navalny's lawyer had criticized that his client was locked up in an isolation cell in a Russian penal camp.
Navalny suffers from fever, chills and cough, but receives no medical help.
At the beginning of the week, 290 Russian doctors wrote an open letter to Kremlin chief Vladimir Putin in which they advocated treatment for Navalny.
"The conditions of detention and the external appearance of Alexei Navalny cause us great concern for his life and health," it said.
Among other things, the doctors demanded that doctors be granted access to the well-known opposition leader.
"We demand an end to the abuse of Alexei Navalny."
The wife of the Russian opposition politician, Yulia Navalnaya, contacted the administration of the penal colony in Melekhovo, about 260 kilometers northeast of Moscow, urging them to send medicine to her husband: "Are you even human?" Navalnaya wrote on Instagram.
»When you come home from work, your parents and children will be waiting for you at home.
What's going on in your heads, how do you live when you're happy that you deliberately made someone sick, that you don't take care of them and don't give them medicine?"
Navalny is in the prison camp under particularly harsh prison conditions for alleged fraud.
Last May, a court upheld his prison sentence.
Internationally, he is considered a political prisoner and one of Putin's harshest critics.
