Start taking your Hytrin Tablets at Day 1 marked START on the strip. This is a white tablet, and you should take it by mouth just before going to bed.

This strip is marked with the days of the week to help you remember if you have taken your tablet. For instance, if you start taking tablets from this strip on a Wednesday, take one tablet from a space marked Wednesday.
