What happens if I forget to take my tablets?

When most forms of blood pressure treatment are stopped, blood
pressure only climbs slowly over days or even weeks. Missing out a single
tablet will not, therefore, have any serious effect unless this is done
frequently. In that case control of blood pressure will be less than perfect.
When a tablet is forgotten, you should not, therefore, take an extra tablet
next time, but continue as though you had not forgotten a single dose.
One or two of the less commonly used tablets cause ‘rebound’ high
blood pressure after a day or two if they are stopped suddenly. It is essential,
therefore, that if, for any reason, you feel that your tablets have to be
discontinued, you discuss this with your doctor. It is also, of course, a
commonsense precaution to take an adequate supply of tablets when
travelling.
