How To Take Ranitidine


Ranitidine is known as an H2 blocker. It works by reducing the amount of acid in your stomach. It is used to prevent and treat heartburn and other symptoms caused by too much acid in the stomach (acid indigestion).

How to use Ranitidine Hcl Tablet

To treat heartburn and acid indigestion, take 1 tablet with a glass of water as needed, unless otherwise directed by your doctor. Swallow the tablet whole without chewing. Ranitidine can be taken with or without food.

To prevent heartburn and acid indigestion, take ranitidine 30-60 minutes before eating food or drinking beverages that can cause indigestion.

Do not take more than 2 tablets in 24 hours unless directed by your doctor. Follow all directions on the product package. If you are uncertain about any of the information, consult your doctor or pharmacist.

Stop taking this medication and call your doctor promptly if your symptoms continue after you begin taking it, or if they do not improve after you have been taking this medication for 14 days in a row. Do not take this medication for more than 14 days in a row without talking with your doctor.

What Are Acid Reducers and how do They Work?

Proton Pump Inhibitors (PPIs) and H2 Blockers are medications that are both approved for treating chronic heartburn or GERD. Both of these medications help to suppress gastric acid secretion in the stomach1. However, there are key differences between the two.

According to Very Well, PPIs shut down the proton pumps in the stomach, while H2 Blockers block the histamine receptors in acid-producing cells in the stomach.

Another difference lies in their onset. PPIs take longer to take effect. However, they work over a longer period of time. In contrast, H2 Blockers take effect within an hour, but they work over a shorter period of time.

Medication like Nexium and Prevacid are PPIs, while Zantac and Pepcid are H2 Blockers.

Unlike antacids, PPIs or H2 Blockers are taken as a measure to treat frequent heartburn or GERD, not just when symptoms arise.
