Antacids are over-the-counter (OTC) or prescription medications designed to treat heartburn, indigestion, and acid reflux. They work by neutralizing stomach acid and are generally considered safe for short-term or occasional use.
However, they may cause side effects and pose health risks when used for longer periods, especially when used with other substances like alcohol. Mixing antacids and alcohol can be harmful and has the potential to exacerbate the unwanted effects of both.
How Do Antacids Interact With Alcohol?
Antacids come in many different types, though each serves the same purpose—to neutralize gastric acid and relieve discomfort.
Most of the antacids available on the market are a combination of aluminum and magnesium hydroxide. Others contain sodium carbonate (chalk) and sodium bicarbonate, commonly known as baking soda. Some popular brands of antacids include Tums, Alka-Seltzer, and Bromaseltzer.
Proton pump inhibitors (PPIs) are another popular antacid. These medications work by reducing the amount of stomach acid made by glands in your stomach lining. Unlike traditional antacids, these are also used to treat ulcers and damage to the lower esophagus caused by acid reflux.
Studies show that around 20% of Americans experience symptoms of gastroesophageal reflux disease (GERD) weekly.
Some antacids are available over the counter, while others require a prescription.
Many different types and brands of PPIs are available, including:
- Esomeprazole (Nexium)
- Omeprazole (Prilosec)
- Lansoprazole (Prevacid)
- Pantraprozole (Protonix)
- Rabeprazole (AcipHex)
- Dexlansoprole (Dexilant)
- Omeprazole with sodium bicarbonate (Zegerid)
Each medication will have unique side effects. Some common side effects of antacids in general include:
- Constipation
- Diarrhea
- Headache
- Nausea
- Itching
- Kidney stones
- Calcium loss
- Osteoporosis (weak bones)
You may be wondering, can you take antacids with alcohol safely?
If you are taking antacids, you can still consume alcohol in moderation. However, it’s important to realize that taking the two together may worsen your gastrointestinal symptoms or cause interactions.
Alcohol increases stomach acid and is associated with a greater risk of gastroesophageal disease. Mixing antacids and alcohol regularly may increase your risk for long-term health problems.

You may not notice immediate harm from occasionally mixing antacids and alcohol. However, the health risks of both are increased when you combine them, especially with chronic use.
Some short-term risks of antacids include:
- Rapid heartbeat
- Sudden changes in blood pressure
- Increased alcohol effect
Long-term risks associated with antacid use include:
- Chronic kidney disease
- Chronic liver disease
- Fatal cardiovascular disease
- Upper gastrointestinal cancer
- Bleeding in the gastrointestinal tract
Not much is known about antacids’ effect on alcohol absorption. However, research has shown that certain antacids, such as ranitidine (Zantac), increase alcohol absorption. Ranitidine has been taken off the market after an association was found between its use and gastrointestinal cancers.
Still, many of the antacids on the market do carry risks. For example, the U.S. Food and Drug Administration warned about serious bleeding in the stomach and gastrointestinal tract that can occur from taking aspirin-containing antacids. These include brand names like Alka-Seltzer Original and Zee-Seltzer.
Gastrointestinal bleeding risk is also associated with PPI use. Researchers have found that the risk increases with the duration of PPI use, regardless of the dosage size. The risk of bleeding is even higher if you consume more than three alcoholic drinks per day or have a history of stomach ulcers.
FAQs About Mixing Alcohol and Antacids
If you are concerned about antacids’ effect on alcohol, you can take steps to avoid mixing the two. You may be able to use both antacids and alcohol in moderation without any serious side effects.
Alcohol increases gastric acid in the stomach, while antacids help to neutralize stomach acid. If you are experiencing heartburn or related symptoms after drinking, antacids may temporarily relieve your symptoms.
However, antacids are meant for occasional use and do carry risks when taken in the long term, and those risks may increase when combined with alcohol.
If you have already taken antacids and alcohol, monitor yourself closely for adverse reactions. If you notice a rapid heartbeat, sudden increases in blood pressure, or other side effects, reach out to your doctor for support.
Certain antacids may make the effects of alcohol stronger. Be mindful of how much you consume, as you may become more intoxicated than you intended.
If you are prescribed antacids and want to consume alcohol, you may be able to do so safely in moderation. It is best not to mix the two if possible.
For example, you may consider taking your antacid in the morning and consuming alcohol in the evening. To ensure safety, talk with the doctor who prescribed your antacids and ask for their recommendation.
Ask about antacids that are safe with alcohol and whether your specific antacid medication has any known interactions with alcohol.
It can be challenging to manage the symptoms of alcohol addiction and acid reflux when the two co-occur.
Alcohol use can make acid reflux worse and increase the risks associated with antacid medications If you find it difficult to control your alcohol use despite negative consequences, you may want to consider getting a professional assessment. An inability to stop drinking is one of the clinical criteria for diagnosing alcohol use disorder.
If you are struggling with alcohol use disorder, you may benefit from professional treatment such as counseling, medications, or attending an inpatient or outpatient rehab facility.
Quitting or reducing your alcohol consumption would likely lessen some of your acid reflux symptoms. It will also make your antacid medications safer to use.
