Kremlin critic Alexei Navalny has been discharged from the hospital in Berlin where he has been treated after falling ill on a domestic flight in Siberia last month.
"The patient's condition had improved sufficiently for him to be discharged from acute inpatient care," the Charite hospital said in a statement on Wednesday.
"Based on the patient's progress and current condition, the treating physicians believe that complete recovery is possible. However, it remains too early to gauge the potential long-term effects of his severe poisoning," it added.
Berlin says tests in Germany, France and Sweden have determined Navalny was poisoned with a Novichok nerve agent and the West has demanded an explanation from Russia.
Moscow has said it is yet to see evidence of a crime and has declined to open an investigation so far, instead of opening a pre-investigation probe. The Kremlin has denied any involvement.
"The decision to make details of Mr. Navalny's condition public was made in consultation with the patient and his wife," the hospital said.
