I would like to take my 1 Nexium pill a day pretty soon after I wake up, but I heard that it is best to take these pills at the same time everyday. I usually wake up at 10am, but at least twice a week, I may randomly get up at 7am. In the latter case, should I Take the pill around 7-ish, or just wait the 3 hours?
I don't know that your schedule is ideal, but based upon the instructions provided with the Nexium you should take it prior to eating. Most PPI's have the same recommendation. My GI doc also directed me to take mine 1/2 hour-1 hour prior to a meal. The only PPI exception I've had to that is the Kapidex with its time release capsule.
If you really have a concern about your schedule, you should talk to your Pharmacist or doctor. Also, most websites from the makers of a prescription have the instructions on usage.
