Key takeaways
Over-the-counter antacids, H2 blockers like cimetidine and nizatidine, and proton pump inhibitors (PPIs) such as omeprazole and esomeprazole, offer alternatives to famotidine for treating heartburn and related conditions.
Famotidine works by blocking histamine type 2 receptors in the stomach, reducing acid production, but alternatives may be sought due to inefficacy or side effects.
For heartburn or mild GERD, famotidine alternatives include antacids, other H2 blockers, proton pump inhibitors (PPIs), and natural alternatives like baking soda or aloe vera juice.
Famotidine is an over-the-counter (OTC) medication that is used to treat heartburn, indigestion, and upset stomach. Higher-dose prescription famotidine is used to treat gastroesophageal reflux disease (GERD), erosive esophagitis, and gastric or duodenal ulcers. Famotidine reduces stomach acid production, so the most appropriate alternative drugs are other drugs that reduce or neutralize stomach acid. Natural alternatives, such as dietary changes, home remedies, and lifestyle changes, can help control heartburn, indigestion, and even mild GERD, but cannot substitute for prescription medications for more serious acid problems.

What can I take instead of famotidine?
When famotidine is not the right medication for stomach acid problems, the choices are limited to other H2 blockers, proton pump inhibitors, and antacids.
Let’s start with antacids. These are mineral salts, like sodium bicarbonate. They don’t reduce acid levels, but instead they neutralize stomach acid. Antacids come in a variety of familiar names, like Alka-Seltzer and Tums, and are a good substitute for over-the-counter famotidine. They can also be taken along with famotidine or other acid reducers. Antacids can provide faster relief from stomach acid problems, while famotidine can provide longer-term relief. Famotidine and antacids are sometimes combined in the same medication, like Pepcid Complete (famotidine-calcium carbonate-magnesium hydroxide).
Other H2 blockers or H2 receptor antagonists worth considering instead of famotidine include Tagamet (cimetidine) and nizatidine. They work similarly to famotidine for treating heartburn, acid reflux, and stomach ulcers. Like famotidine, cimetidine and nizatidine are available in both over-the-counter and prescription dosage strengths.
If the issue is that famotidine isn’t working well, it may be time to consider a more potent class of acid reducers called proton pump inhibitors (or PPIs), like Prilosec OTC (omeprazole) or Protonix (pantoprazole). Some PPIs, too, are sometimes sold in both prescription and OTC strengths. They are stronger acid reducers and usually work better to treat stubborn acid reflux symptoms.
Buying over-the-counter acid medications can be confusing. Another name for famotidine OTC is “Acid Reducer,” but make sure to look at the ingredients list. “Acid Reducer” can be a name for any nonprescription H2 blocker or PPI.

Top 3 famotidine alternatives
1. Over-the-counter antacids
If you need immediate relief from mild, occasional heartburn, try a fast-acting antacid. Popular antacid brands include Tums (calcium carbonate), Rolaids (calcium carbonate-magnesium hydroxide), Alka Seltzer (aspirin-anhydrous citric acid-sodium bicarbonate), Maalox (aluminum hydroxide-magnesium hydroxide-simethicone), and Gaviscon (aluminum hydroxide-magnesium carbonate). These medications are safe, inexpensive, act fast, and can be taken several times a day if needed. They may also contain other symptom-relief medications, such as a pain reliever (aspirin), an intestinal gas reducer (simethicone), or an acid reducer.
The downside is that their effects often don’t last that long, and they are not indicated for erosive esophagitis or peptic ulcer disease. They are, however, sometimes used along with H2 blockers or PPIs to treat heartburn, GERD, erosive esophagitis, or ulcers.

2. H2 blockers
These are drugs in the same class as famotidine, and include cimetidine and nizatidine. These alternatives are just as effective as famotidine and are usually inexpensive. Cimetidine is also sold in a prescription-strength version. The potential downside is that they will likely present the same issues as your original reasons for switching medications in the first place.
3. Proton pump inhibitors
Proton pump inhibitors, or PPIs, are more powerful acid reducers than H2 blockers like famotidine. However, they may take longer to work. PPIs include Prilosec (omeprazole), Nexium (esomeprazole), Protonix (pantoprazole), Prevacid (lansoprazole), Aciphex (rabeprazole), Dexilant (dexlansoprazole), and Zegerid OTC (omeprazole-sodium bicarbonate).
Just as people can buy famotidine over the counter, they can purchase many PPIs over the counter, including omeprazole (Prilosec OTC), esomeprazole (Nexium 24HR), and lansoprazole (Prevacid 24HR).

Natural alternatives to famotidine
Natural remedies and lifestyle changes may help with mild heartburn or GERD. Conditions that require prescription medication can benefit from natural remedies but will usually require long-term use of PPIs.
Lifestyle and dietary changes are a key component of handling indigestion or GERD. Start by avoiding certain foods, such as fatty foods, acidic foods, greasy foods, and alcohol. Eat smaller meals and add alkaline foods to the menu, such as melons or bananas. Avoid lying down too soon after a meal.
Baking soda, or sodium bicarbonate, is a base that can neutralize the acid in the stomach. Mixing a small amount in a glass of water when heartburn occurs can be effective as a fast-acting antacid.
Always ask your healthcare provider before using natural remedies to treat heartburn or any other condition, as they can affect your other medications or health conditions, causing potential for serious side effects.

How to switch to a famotidine alternative
If you’re considering switching from famotidine to an alternative, your healthcare provider may recommend tapering your use to prevent rebound acid reflux (though this is less common than with PPIs). As you are tapering off the famotidine, you can try the alternative medication, whether it is another H2 blocker, a stronger PPI medication, or a fast-acting antacid. Remember, if you have any questions about switching medications or if you experience worsening symptoms despite switching, contact your healthcare provider for medical advice.
