What happens if I miss a dose?
Take the missed dose as soon as you remember. If it is almost time for your next dose,
skip the missed dose and take the medicine at the next regularly scheduled time. Do not take extra medicine to make up the missed dose.
If you miss doses for several days in a row, call your doctor before taking any additional
doses. You may need to use a lower dose of doxazosin for a short time.
