Can you take Omeprazole with Zantac?

22nd October 2019

Both Omeprazole and Zantac are prescribed for the treatment of ulcers. Naturally, you may be wondering whether you can take both of these medications together at the same time. In short, there are no known conflicts between these two medicines. They are, however, both prescription-only medications - so you will have the opportunity to discuss how Omeprazole and Zantac complement each other if your doctor deems the combination appropriate for you.

What happens if you take Omeprazole with Zantac?

Both of these drugs work to treat conditions such as ulcers and gastroesophageal reflux disease (GERD) which is caused by stomach acid. They accomplish this in different ways, one as a proton-pump inhibitor and the other as an H2-blocker. These methods are not contrary to each other and can be used simultaneously if your doctor deems it the proper course of action to treat your condition.

Omeprazole (Prilosec) and Zantac compared

How do each of these drugs work to treat ulcers and GERD? Find out how they compare to each other below.

How does Omeprazole work to reduce stomach acid?

Omeprazole works by decreasing the amount of acid the stomach produces. Omeprazole is a "proton pump inhibitor". In layman's terms, this means that a particular enzyme that is necessary to produce stomach acid is prevented from activating. The end result is having less acid in your stomach.

How does Zantac work to reduce stomach acid?

Zantac has a different method of accomplishing the same thing as Omeprazole. Zantac (brand name), also called ranitidine (generic), works by preventing the production of acid-producing cells in the stomach. It accomplishes this in a different way than Omeprazole does, namely, it blocks histamine-2. For this reason, Ranitidine is also called an "H2 blocker".

Side effect similarities between Omeprazole and Zantac

All prescription medications have some type of potential side effects. Both Omeprazole and Zantac share similar side effects, which are listed below. Not everyone will experience these side effects. If you experience any of the following side-effects in a serious way, contact your doctor immediately.

Differences

People who take omeprazole can sometimes experience include rash and dizziness. These two side-effects are generally not experienced by those who take Zantac. If you experience serious side effects involving rash and dizziness, contact your doctor immediately.

People who take Zantac will sometimes experience fatigue and insomnia. People who take Omeprazole do not typically experience fatigue and insomnia. If you are experiencing these side-effects in a serious manner, contact your doctor immediately.

Which is more effective, Omeprazole or Zantac?

Omeprazole (a proton pump inhibitor, or PPI) is very effective in shutting down acid production of the stomach. PPIs are most effective during the day. They are also extremely effective after meals. For this reason, it is recommended that you take Omeprazole immediately prior to meals. PPIs are not, however, particularly effective at night.

Zantac and other H2-receptor-blockers, on the other hand, are very effective at night. A good time to take Zantac is just before bed. These stomach-acid reduction medications both serve the purpose of reducing stomach acid, in slightly different ways. Take this into consideration when trying to find the best ulcer or GERD medication.

What is Omeprazole?

Omeprazole is the generic medication also sold under the brand name Losec, used in the treatment of gastroesophageal reflux disease, peptic ulcer disease, and Zollinger–Ellison syndrome. It is used to prevent upper gastrointestinal bleeding in people who are at high risk of that condition.

What is Zantac?

Zantac, also sold under its generic name Ranitidine, is a medication that decreases stomach acid production. It is commonly used in the treatment of peptic ulcer disease, gastroesophageal reflux disease, and Zollinger–Ellison syndrome. There is also evidence it can benefit people suffering from hives.
