[Tex/LaTex] Create Tikz Single arrow label text orthogonal to arrow direction

Question

I have this macro to create down arrows

\newcommand{\arrowdown}[1]{
\tikz[baseline=-1ex]{\node [draw, fill=orange, single arrow, minimum height=3.5ex, single arrow head extend=1ex, rotate=-90] {#1};}
}

Which gives me the following arrow

However what I want is for the label to be by the side of the arrow, written horizontally. Since the arrow is rotated by -90, I want the label text to be rotated by 0 degrees, and start to the right of the arrow itself.

EDIT: Sketch of what I want to get, except I would prefer to have that arrow styled like the one above:

Answer 1

rotate rotates the whole thing, shape border rotate the contour. This example is more or less identical to what's done in the first example on p. 785 of the pgfmanual.

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{shapes.arrows}
\newcommand{\arrowdown}[1]{
\tikz[baseline=-1ex]{\node [draw, fill=orange, single arrow, 
minimum height=3.5ex, single arrow head extend=1ex,
shape border uses incircle,shape border rotate=-90] {#1};}
}
\begin{document}
\arrowdown{Pft}
\end{document}

Or for the updated question:

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{shapes.arrows}
\newcommand{\arrowdown}[1]{
\tikz[baseline=-1ex]{\node [draw, fill=orange, single arrow, 
minimum height=3.5ex, single arrow head extend=1ex,
rotate=-90](arr) {}; \node[anchor=west] at ([xshift=0.5em]arr.90) {#1};}
}
\begin{document}
\arrowdown{Pft}
\end{document}
