Heartburn Around the Clock 

Prilosec OTC


While the physiological processes involved in heartburn at night are the same as during the day, you may perceive your heartburn symptoms differently at night because of the orientation of your body. The same condition—heartburn—can cause different sensations during the day versus night.


In a survey done in 2003, 13% of 1,000 adults who experienced heartburn at least weekly had only nighttime episodes; 20% reported only daytime heartburn.1 Altogether, 79% of the heartburn sufferers reported experiencing heartburn at night. Of these, 75% reported that heartburn had a negative impact on sleep; 63% indicated that heartburn adversely affected their ability to sleep well; and 40% reported impaired functioning the next day. The prevalence of sleep disturbances increased directly with the incidence of heartburn at night.


With one pill a day, Prilosec OTC® offers day and night protection to help alleviate your frequent heartburn symptoms for 24 hours.* At night, the body’s sleeping position allows for easier passage of acidic fluid and gas up to the esophageal sphincter, and up into the esophagus. This can cause some of the most uncomfortable symptoms of heartburn. Reducing the number of these instances can reduce the number of sleep disturbances due to heartburn, and a more restful night’s sleep can result in a more productive day.
