Pepcid vs Maalox
Introduction
For patients struggling with heartburn or other types of digestive discomfort, certain drugs that neutralize or limit the production of stomach acid can help in relieving gastric distress and managing symptoms. Pepcid and Maalox are two such medications frequently used for these conditions. They each have different modes of action but both aim to alleviate discomfort associated with excess stomach acid.
Pepcid, also known as famotidine, is classified as a histamine-2 (H2) blocker. It functions by reducing the amount of stomach acid produced by blocking signals from histamine, which stimulates acid secretion. On the other hand, Maalox is an antacid that works more directly by neutralizing existing stomach acid to provide quick relief from symptoms like heartburn and indigestion. Its primary active ingredients are magnesium hydroxide and aluminum hydroxide.
What is Pepcid?
Famotidine (the generic name for Pepcid) is a H2 blocker which represents a significant advancement from the earlier class of antacids such as Maalox. Famotidine was first approved by the FDA in 1986. Pepcid works by reducing the amount of acid your stomach produces, providing relief from conditions such as gastroesophageal reflux disease (GERD). It's prescribed to treat and prevent ulcers in the stomach and intestines, conditions where the stomach produces too much acid, and heartburn related to acid indigestion. The action of famotidine is more targeted towards blocking histamine receptors on parietal cells in the stomach lining that produce gastric acid; this results in it having fewer side effects than traditional antacids like Maalox that neutralize existing stomach acids but do not reduce their production.
What conditions is Pepcid approved to treat?
Pepcid is approved for the treatment of various stomach and esophagus problems:
- Gastroesophageal reflux disease (GERD)
- Duodenal and gastric ulcers
- Zollinger-Ellison syndrome
- Heartburn associated with acid indigestion
On the other hand, Maalox is recommended for:
- Relief from heartburn, sour stomach, or acid indigestion
- Painful inflammation of the stomach lining known as gastritis
- Stomach discomfort linked to overindulgence in food or drink.
How does Pepcid help with these illnesses?
Pepcid works to manage heartburn and stomach ulcers by decreasing the amount of acid produced in the stomach. It does this by blocking histamine at H2 receptors found on the gastric parietal cells, thus inhibiting gastric acid secretion. Acid is a substance that can damage tissues and cause discomfort when present in excessive amounts, especially in parts of the body not designed to withstand its corrosive effects such as esophagus or duodenum. It is thought that individuals with conditions like gastroesophageal reflux disease (GERD) have relatively higher levels of stomach acid production. Therefore, by reducing this excess of acid production, Pepcid can limit the negative effects associated with these conditions and help patients control their symptoms.
What is Maalox?
Maalox is a well-known brand for antacids that contain two key ingredients: magnesium hydroxide and aluminum hydroxide. These elements neutralize stomach acid by reducing the production of pepsin, a protein-digesting enzyme. Maalox was first approved by the FDA in 1949 and remains available over-the-counter today.
As an antacid, Maalox does not inhibit any neurotransmitters or reuptake inhibitors; instead it works directly on stomach acid to deliver relief from indigestion symptoms such as heartburn and sour stomach. Its action profile is therefore quite different to those of drugs like Pepcid (famotidine), which are H2 antagonists that work by blocking histamine at the receptors of acid-producing cells.
One notable benefit of Maalox is its rapid onset of action compared to Pepcid - usually providing relief within minutes rather than hours. However, potential side effects can include constipation or diarrhea due to its active ingredients.
What conditions is Maalox approved to treat?
Maalox is widely recognized and administered for the effective treatment of:
- Dyspepsia, commonly known as indigestion
- Gastric acid reflux, often referred to as heartburn
- Stomach ulcers
It's a trusted antacid that combats stomach discomfort by neutralizing gastric acid in your digestive tract.
How does Maalox help with these illnesses?
Maalox is a type of antacid that works by neutralizing acid in the stomach. It contains two active ingredients, magnesium hydroxide and aluminum hydroxide, which directly act to reduce acidity levels in the gastrointestinal tract. This quick action helps alleviate symptoms associated with heartburn such as discomfort and indigestion. However, Maalox provides relatively temporary relief compared to Pepcid (famotidine) because it does not block histamine receptors on parietal cells like famotidine does; these cells are responsible for producing stomach acid when stimulated by histamines. Hence, Maalox might be more suited for immediate symptom relief while Pepcid could be considered for longer-term management of conditions like GERD or peptic ulcer disease.
How effective are both Pepcid and Maalox?
Both famotidine (Pepcid) and Maalox have a long history of success in treating patients with heartburn, gastritis, and other acid-related disorders. They were first approved by the FDA several years apart and since they act on different aspects of stomach acid production, they may be used under varying circumstances. The effectiveness of Pepcid in alleviating symptoms like heartburn was directly studied against antacids like Maalox in double-blind clinical trials; both drugs exhibited similar efficacy at managing these symptoms as well as promising safety profiles.
A 1986 study reported that Pepcid is very effective starting from the first day treatment even at low doses to control gastric acidity over 24 hours. Its side effect profile is favorable compared to many other medications for stomach acidity and it is generally well-tolerated even among elderly populations. This same study reports that Pepcid has become one of the most widely prescribed H2 blockers worldwide due its potent inhibition of gastric secretion.
On the other hand, a review indicated that Maalox seems to provide immediate relief from heartburn but does not work for extended periods unlike H2 blockers or proton pump inhibitors. Nonetheless, it is typically considered a first-line treatment option for immediate symptom relief while waiting for longer acting treatments to take effect. Most research involves using Maalox alongside an H2 blocker or PPI so data confirming its efficacy as a stand-alone treatment are less robust than those for Pepcid.Furthermore,the evidence supporting use of antacids such as Maalox beyond immediate symptom relief still lacks strong support.Nonetheless,due to its quick onset,Maallox can be an optimal choice for patients who require instant symptomatic relief.
At what dose is Pepcid typically prescribed?
Oral doses of Pepcid for adults range from 20-40 mg/day, but research suggests that 20 mg/day is adequate for treating most cases of gastroesophageal reflux disease and peptic ulcers. For children and adolescents, the initial dose may be as low as 0.5 mg/kg. If no response is seen after a few weeks, the dosage can be increased under medical supervision. However, in any case, the maximum dosage should not exceed 40 mg/day.
On the other hand, Maalox is usually taken on an "as needed" basis for relief of heartburn or indigestion symptoms. Adults typically take one to two tablespoons (15-30 ml) every hour or as directed by a doctor while children's dosages are determined by their doctor based on weight and age considerations.

At what dose is Maalox typically prescribed?
Maalox therapy is often initiated with a dosage that can be adjusted based on the severity of symptoms. For adults and children over 12 years, it's usually recommended to take two to four teaspoons (10-20 ml) by mouth, every hour as needed. The dose can then be reduced gradually depending on symptom relief. Do not exceed 12 teaspoons (60 ml) in a 24-hour period or use maximum dosage for more than two weeks unless directed by a physician. Always ensure proper hydration when taking Maalox to maintain renal function effectively especially if you are using it for prolonged periods.

For those taking Maalox, watch out for signs of high magnesium levels in the blood such as muscle weakness and irregular heartbeat. In rare cases, severe kidney problems may occur when using this drug for a long time period. If you notice any significant changes in the amount of urine produced or if you experience symptoms like ankle swelling and unusual tiredness while on either medication, contact your healthcare professional immediately.
What are the most common side effects for Maalox?
Maalox can potentially cause these side effects, although they are generally mild:
- Stomach cramps
- Diarrhea or constipation
- Nausea or vomiting
- A chalky taste in the mouth
- Increased thirst due to magnesium in Maalox that may lead to increased urination
- Headache is also a possible but less common side effect.
Note that severe reactions such as muscle weakness, slow heartbeat, and confusion are infrequent but should prompt immediate medical attention.
Are there any potential serious side effects for Maalox?
Although Maalox is generally well-tolerated, it's important to be aware of potential adverse effects that may occur in rare instances. These could include:
- Signs of an allergic reaction such as hives, itching, or a rash; fever; swollen glands; difficulty breathing; swelling in your face or throat.
- Symptoms indicating high levels of aluminum/magnesium in the body like muscle weakness, slow reflexes, nausea and vomiting.
- Changes in mental status including confusion or unusual mood swings
- Unusually slow heartbeats or irregular rhythms
- Vision changes: blurred vision or seeing halos around lights
- Severe stomach/abdominal pain accompanied by bloody/black stools and vomit that looks like coffee grounds
If you experience any of these symptoms while taking Maalox, immediately cease usage and consult with your healthcare provider.
Contraindications for Pepcid and Maalox?
Pepcid and Maalox, like most other acid reducers and antacids, can cause side effects. If you notice your symptoms of indigestion worsening or any signs of allergic reaction, seek immediate medical attention.
Neither Pepcid nor Maalox should be taken if you are taking certain prescription drugs without consulting with your healthcare provider first. Some medications may interact adversely with these over-the-counter treatments. For example, medications such as tetracycline, digoxin or ketoconazole require a normally acidic stomach environment for absorption so the use of antacids or acid reducers could limit their effectiveness.
Always inform your physician about which medications you are taking; some will require an adjustment to dosing schedule in order not to interfere with the action of Pepcid and Maalox. In addition, long-term usage of these agents should be under the supervision of a physician due to potential negative impacts on kidney function and mineral balance.
How much do Pepcid and Maalox cost?
For the brand name versions of these drugs:
- The price of 30 tablets of Pepcid (20 mg) averages around $17, which works out to approximately $0.57/day.
- The price for a bottle containing 12 fluid ounces (355 ml) of Maalox suspension averages around $9, working out to about $0.75 per day if you take the recommended dose.
Thus, if you are taking the standard adult dosage for each medication (i.e., one tablet twice daily for Pepcid and two teaspoons four times daily for Maalox), then generic Pepcid is less expensive on a per-day treatment basis than Maalox. Please note that cost should not be your only consideration when determining which drug is best suited to your needs.
In terms of generic versions:
- Famotidine (generic version of Pepcid) costs between $4 and $15 depending on quantity purchased, translating into a range from as low as $0.13 up to roughly $.50/day at typical dosages.
- Aluminum hydroxide/magnesium hydroxide/simethicone suspension - oral (the active ingredients in Maalox), typically costs between $5 and $10 for similar quantities as above, with daily costs starting at just under $.20/day and reaching up to about $.33/day based on common dosage instructions.
Popularity of Pepcid and Maalox
Famotidine, available in generic form and under brand names such as Pepcid, is a widely used H2 receptor antagonist that helps decrease the production of stomach acid. In 2020, it was estimated to have been prescribed to approximately 3 million people in the US. Famotidine accounted for around 15% of all prescriptions for H2 receptor antagonists.
On the other hand, Maalox is an over-the-counter antacid containing magnesium hydroxide and aluminum hydroxide. It works by neutralizing stomach acid on contact rather than decreasing its production like famotidine does. Although specific prescription figures are not available due to its over-the-counter status, Maalox remains a popular choice among consumers who need immediate relief from heartburn or indigestion symptoms. Both famotidine and Maalox work effectively against their respective conditions; however, they differ significantly in how they achieve these results.
Conclusion
Both Pepcid (famotidine) and Maalox (a combination of aluminum hydroxide and magnesium hydroxide) have proven records in relieving digestive discomfort, such as heartburn or indigestion. They are backed by numerous clinical studies indicating their effectiveness over placebos. While both aim to reduce stomach acidity, they work differently: Pepcid is an H2 blocker that reduces the production of stomach acid, while Maalox acts as an antacid that neutralizes existing stomach acid.
In some cases, these drugs might be used together for comprehensive relief from symptoms; however, this should always be under a healthcare provider's direction due to potential interactions. For instance, Pepcid can affect the absorption of other medications if not properly timed.
While both are available over-the-counter without need for prescription making them easily accessible and cost-effective especially for those paying out-of-pocket, choosing between the two often depends on the individual’s specific needs and circumstances - whether it is immediate symptomatic relief needed (Maalox), or prevention of recurring issues like gastroesophageal reflux disease (Pepcid).
The side effect profiles for both drugs are relatively benign but differ slightly; common side effects with H2 blockers like Pepcid may include headache or constipation while antacids like Maalox may cause diarrhea or constipation. Users should note any unusual reactions when starting treatment and seek medical help immediately if severe symptoms occur.
