Given Zantac (ranitidine) 150mg to take twice a day. Half a tablet once a day works the same. Is this ok instead of 2? Male 22

Full prescription dosing is 300 mg twice daily to heal acid-related injury.

Baking soda: If cost is an issue, and your are already taking 300mg of generic Zantac (ranitidine) a day, then you could occasionally try taking a level teaspoon of baking soda in about two ounces of water for further relief.

Been taking Zantac (ranitidine) 150 for acid reflux once a day for the past 2-3 days. I feel like I'm coming down with a cold, can I take DayQuil tablets with it?

I wouldn't.: Over the counter cough and cold medicines have no proven benefit and many side effects. See http://tinyurl.com/osmaxzo Also, if your cold symptoms started after taking the Zantac, (ranitidine) and you have never had it before, I would stop it for now, to be sure that did not play a role in your new symptoms. You can safely use liquid antacids or tablet antacids (like calcium carbonate) for stomach upset. ...Read more
