Yes: Zantac (ranitidine) has a totally different mechanism of action than Prilosec. It is safe to take up to 150 mg twice a day. Starting a lower dose of 150 mg once a day may be advisable and if this is not enough to control your symptoms, you may increase it to 150 mg twice a day. It is important to make sure that you are not infected with H.pylori. H.pylori requires specific treatment.
