Relatives of jailed activists Alaa and Sanaa Abdel-Fattah have ended their hunger-strike, they announced on Wednesday.
Their mother, Laila Soueif, and their sister, Mona Seif, started a hunger-strike on 4 September in solidarity with them after they were jailed under a controversial protest law.
"I am very depressed as I write this [and] I am unable to write anything more," Soueif said in a Facebook post.
Mona Seif also wrote a public post marking the end of her strike, where she expressed support for her brother and sister and other hunger-striking detainees.
"[The experience] made me appreciate more and more the struggle of the brave [people] detained in our country's prisons," she said, adding that giving up food is like giving up the last of daily rituals that those detained have left behind in jails.
Alaa is currently detained pending retrial in the "Shoura Council" case, in which he and 24 others are accused of breaking the protest law in November 2013.
Sanaa and 22 others are detained also pending retrial over an illegal protest near Ittihadiya presidential palace last summer.
Both Alaa and Sanaa are on hunger strike to demand the protest law be amended and the release of all people detained under the law.
A major hunger strike campaign was taken up by dozens of activists and supporters in September.
Hundreds have been arrested in Egypt under the protest law which was introduced in November last year and received widespread criticism from local and international rights groups.
