Generic Prilosec is used for treating heartburn or irritation of the esophagus caused by gastroesophageal reflux disease (GERD). It may also be used for short-term treatment of ulcers of the stomach or small intestines and to help prevent them from coming back; to treat conditions that cause your body to make too much stomach acid (eg, Zollinger-Ellison syndrome).

Regarding the effect: I do notice an increase in bloodflow and a better
stamina using the pills (I use 50mg). A side-effect I have noticed is that
my nose clogs up so I seem like I have a cold for an hour or so after taking
one pill. No other side-effects than that.
