You can work as folows:
solution1 = NDSolve[{Derivative[1][y][x] == 1/(2*y[x]), y[0.01] ==
0.1}, y, {x, 0.01, 1}];
Plot[y[x] /. solution, {x, 0.01, 1}];
or alternatively
solution = NDSolve[{Derivative[1][y][x] == y[x], y[1] == 2}, y, {x,
-3, 3}]
{{y -> InterpolatingFunction[]}}
y[x_] = y[x] /. solution[[1]]
InterpolatingFunction[][x]
Plot[y[x], {x, 0, 3}]
