You could try using the -keep- command with wild-cards...

keep *_01

..should do the trick.  See -man keep- and section 11.2.3
Variable-name abbreviation in the Stata Users Manual.

Senda List,

I have a large housheold survey dataset which includes the variables listed
below. I would like to drop variables with _02 to _46 and only keep the _01
ones. How can I do this?

hvidx_01 to _46 (i.e. hvidx_01, hvidx_02 ... hvidx_46)
hv101_01 to 46
hv102_01 to _46
hv103_01 to _46
hv104_01 to _46
hv105_01 to _46
hv106_01 to _46
hv107_01 to _46
hv108_01 to _46
hv109_01 to _46
hv110_01 to _46
hv115_01 to _46
hv116_01 to _46
hv117_01 to _46

Just for your information, variables with "_01" refers to information for
the household's head which is what I am interested in. The others "_02...
_04" refer to other members of the household.

Thank you for your help.
