Pepcid vs Prevacid
Introduction
For individuals suffering from gastroesophageal reflux disease (GERD) or other types of gastric-acid related conditions, certain medications that reduce the production of stomach acid can be critical in managing discomfort and preventing potential complications. Pepcid and Prevacid are two such drugs often prescribed for these conditions. They differ in their mechanism but both aim to alleviate symptoms by reducing stomach acid levels. Pepcid is classified as an H2 blocker, it works by blocking histamine at the receptors of the stomach cells, thereby reducing production of stomach acid. On the other hand, Prevacid falls into a category known as proton pump inhibitors (PPIs), which function by directly inhibiting gastric acid secretion at the source —the proton pump— within parietal cells in the stomach lining.

What is Pepcid?
Famotidine (the generic name for Pepcid) and Lansoprazole (generic Prevacid) are both used to treat conditions related to the stomach, such as ulcers and gastroesophageal reflux disease. However, their mechanisms of action differ significantly. Famotidine is a histamine-2 blocker that works by reducing the amount of acid produced in the stomach. It was first approved by the FDA in 1986. On the other hand, Lansoprazole belongs to a class of drugs known as proton pump inhibitors (PPIs). They work by blocking an enzyme in the wall of your stomach that produces acid, thereby decreasing levels of this substance.
Lansoprazole tends to be more effective at healing erosive esophagitis due its potent inhibition of gastric acid secretion compared with H2 blockers like famotidine. While both drugs have been associated with few side effects overall, PPIs can sometimes lead to longer-term problems if used excessively or without proper medical supervision — including nutrient deficiencies and increased risk for certain types infections due its profound effect on stomach acidity.
What conditions is Pepcid approved to treat?
Pepcid and Prevacid are both approved for the treatment of various conditions related to stomach acid:
- Gastroesophageal reflux disease (GERD), a chronic condition where stomach acid flows back into the esophagus
- Stomach and duodenal ulcers, which are sores on the lining of your stomach or small intestine
- Zollinger-Ellison syndrome, a rare condition in which tumors in the pancreas or duodenum cause increased production of gastric acid.
Additionally, Prevacid is also used to treat damage from GERD and conditions where the stomach produces too much acid such as Zollinger-Ellison syndrome.
How does Pepcid help with these illnesses?
Pepcid works to manage heartburn and acid reflux by decreasing the amount of acid produced in the stomach. It accomplishes this by blocking histamine at H2 receptors found on gastric parietal cells, which are responsible for secreting gastric acid. Histamine plays a crucial role in triggering these cells to produce and release more stomach acid. By inhibiting this action, Pepcid helps maintain lower levels of acidity for longer periods of time.
On the other hand, Prevacid also treats heartburn and gastroesophageal reflux disease (GERD) symptoms but through a slightly different mechanism. Instead of focusing on histamine, Prevacid directly blocks an enzyme system known as proton pumps located on the inside lining of your stomach's parietal cells that secrete hydrochloric acid into your stomach cavity. Therefore, by inhibiting proton pumps, Prevacid can limit excessive production of gastric acids effectively helping patients manage their condition better.
What is Prevacid?
Prevacid is a brand-name for lansoprazole, which serves as a proton pump inhibitor (PPI). PPIs work by reducing the amount of acid produced in your stomach. Prevacid inhibits an enzyme needed to secrete gastric acid and was first approved by the FDA in 1995. Unlike Pepcid, which is an H2 blocker that works by blocking histamine at the receptors of the stomach cells, Prevacid effectively decreases stomach acid production from its source -- thereby providing relief from symptoms associated with excessive production of stomach acid. This makes it particularly effective in treating conditions like gastroesophageal reflux disease (GERD), peptic ulcers and Zollinger-Ellison syndrome. Its side-effect profile also differs slightly from that of H2 blockers such as Pepcid; common side effects may include headache, nausea and diarrhea but it's less likely to interact with other medications you might be taking.
What conditions is Prevacid approved to treat?
Prevacid is a proton pump inhibitor that's approved for the treatment of:
- Gastroesophageal reflux disease (GERD)
- Stomach and duodenal ulcers
- Erosive esophagitis It also aids in the healing process of these conditions. Prevacid can be used to treat Zollinger-Ellison syndrome, a condition where the stomach produces too much acid. This medication works by decreasing the amount of acid made in your stomach.
How does Prevacid help with these illnesses?
Prevacid, also known as lansoprazole, is a type of medication that works by reducing the amount of acid produced in the stomach. It does this by blocking an enzyme in the wall of the stomach that produces acid. This can help to relieve symptoms such as heartburn, difficulty swallowing and persistent coughing. Prevacid's action on proton pumps plays a significant role in its efficacy as a treatment for conditions like gastroesophageal reflux disease (GERD). Since it has more prolonged effects compared to H2 antagonists like Pepcid, it is often prescribed when a patient doesn't respond well to these types or requires long-term management of their condition.
How effective are both Pepcid and Prevacid?
Both famotidine (Pepcid) and lansoprazole (Prevacid) have established histories of success in treating patients with gastroesophageal reflux disease (GERD), peptic ulcers, and other conditions caused by excess stomach acid. Since they act on different mechanisms to reduce gastric acidity, they may be prescribed under different circumstances.
Famotidine is a histamine-2 receptor antagonist that works by blocking the action of histamine on stomach cells, thereby reducing the production of acid. Lansoprazole is a proton pump inhibitor that works by directly inhibiting the mechanism responsible for secreting acid into the stomach.
A 2009 clinical trial compared famotidine with lansoprazole in alleviating symptoms of GERD; both drugs were found to be effective but with varying degrees of efficacy depending on symptom severity and patient individuality. In this study, none of the metrics used to measure efficacy in treating GERD differed significantly between patients receiving famotidine or lansoprazole overall.
A review conducted in 2011 showed that while both medications are effective at relieving symptoms related to excess stomach acid, lansoprazole was slightly more effective than famotidine at healing erosive esophagitis over an eight-week treatment period.
Nonetheless, because it has been available longer and is now sold over-the-counter like many H2 antagonists, Pepcid might be seen as a first-line treatment option for milder cases or short-term relief from heartburn while Prevacid may serve as a second-line option due to its greater effectiveness against severe forms such as erosive esophagitis.

At what dose is Pepcid typically prescribed?
Oral dosages of Pepcid range from 20–40 mg/day, but studies have indicated that 20 mg/day is sufficient for treating most cases of peptic ulcer and gastroesophageal reflux disease (GERD). Children may be started on a lower dosage depending on their weight and the severity of their symptoms. In either population, dosage can be increased after a few weeks if there is no response. The maximum dosage that should not be exceeded in any case is 40 mg/day. On the other hand, Prevacid typically starts at an oral dose of 15-30mg once daily before meals for up to eight weeks, with some patients requiring additional courses for complete healing or symptom control. For children, doses are adjusted according to weight and condition being treated.
At what dose is Prevacid typically prescribed?
Prevacid treatment typically starts with a dosage of 15 mg/day. The dose can then be increased to 30 mg/day, taken as a single dose in the morning before eating. For conditions like erosive esophagitis, where more intensive treatment is required, your healthcare provider may prescribe doses up to 60 mg per day or recommend taking Prevacid twice daily for a specified period. It's recommended not to exceed the maximum dosage unless under strict medical supervision and guidance due to potential side effects. If there is no response after several weeks of treatment at 30 mg/day, additional evaluation might be necessary.
What are the most common side effects for Pepcid?
Common side effects of Pepcid (Famotidine) might include:

- Rapid heartbeat or irregular heart rhythm
- Sudden dizziness like you might pass out
- Muscle cramps or weakness with unusual tiredness
- New onset seizures or convulsions
- Changes in mood and mental state such as hallucinations and confusion
If you experience any of these symptoms after taking Prevacid, seek immediate medical attention. This list does not cover all possible side effects; always consult your healthcare provider for advice on managing side effects.
Contraindications for Pepcid and Prevacid?
Both Pepcid and Prevacid, along with most other GERD medications, may worsen symptoms of stomach pain in some people. If you notice your stomach discomfort worsening or experience severe side effects such as unexplained weight loss, vomiting (especially with blood), difficulty swallowing, persistent nausea/vomiting or unusual fatigue after taking these drugs, please seek immediate medical attention.
Neither Pepcid nor Prevacid should be taken if you are currently using atazanavir for HIV treatment due to potential interactions that could decrease its effectiveness. Always inform your doctor about any medications you are taking; atazanavir will require a period of about 2 weeks to clear from the system before initiating treatment with either Pepcid or Prevacid to prevent dangerous interactions.
How much do Pepcid and Prevacid cost?
For the brand name versions of these drugs:
- The price of 60 tablets of Pepcid (20 mg) averages around $40, which works out to about $0.67/day, if you are taking a typical dose.
- The price of 30 capsules of Prevacid (15 mg) averages is about $200, working out to approximately $6.67/day.
Thus, if you are in higher dosage range for Prevacid (i.e., 30mg/day or higher), then brand-name Pepcid is less expensive on a per-day treatment basis. Please note that cost should not be a primary consideration in determining which of these drugs is right for you.
For the generic versions - famotidine and lansoprazole respectively - costs are significantly lower:
- Famotidine (10 mg tablets) is available in packs from 30 up to 100 tablets with approximate costs ranging from $0.05 to $0.35 per day depending on dosage and packaging size.
- Lansoprazole is available in packages as small as 14 up to over-the-counter bulk options reaching into the hundreds, with your daily cost starting at roughly just under $1/day and decreasing when purchased in larger quantities due its longer-term nature prescribed use.
Popularity of Pepcid and Prevacid
Famotidine, known by its brand name Pepcid among others, was estimated to have been prescribed to about 2 million people in the US in 2020. Famotidine accounted for just over 20% of H2 antagonist prescriptions (a class of drugs that reduce acid production in the stomach). Its use has remained steady since it first became available as an over-the-counter medication.
Lansoprazole, including brand versions such as Prevacid, was prescribed to approximately 15 million people in the USA during that same year. In the US, lansoprazole accounts for just under 30% of proton pump inhibitor (PPI) prescriptions, a category of medications designed to decrease acid production more effectively than H2 antagonists. The prevalence of lansoprazole has generally increased since its introduction due to its effectiveness and safety profile. It should be noted though that while both are used for similar conditions like GERD and ulcers, PPIs like Prevacid tend to be more potent and longer lasting compared to H2 blockers like Pepcid.
Conclusion
Both Pepcid (famotidine) and Prevacid (lansoprazole) have a longstanding history of usage in patients with gastroesophageal reflux disease, peptic ulcer disease, and other conditions where reducing stomach acid is beneficial. They are backed by numerous clinical studies indicating that they are more effective than placebo treatments. In some cases, the drugs may be combined but this should be under strict medical supervision as they also come with their own contraindications.
Due to their different mechanisms of action - Pepcid being an H2 blocker that slows down the production of stomach acid, and Prevacid being a proton pump inhibitor that almost entirely stops stomach acid production - they tend to be prescribed under different circumstances. Prevacid is typically considered for more severe or persistent symptoms while Pepcid might be utilized for milder or intermittent issues.
Both drugs are available in generic form which represents significant cost savings especially for those who must pay out-of-pocket. Both famotidine and lansoprazole may require an adjustment period meaning effects may not immediately be noticeable.
The side effect profile differs somewhat between these two medications; both generally well-tolerated but potential side effects such as headaches, diarrhea, constipation can occur with either drug. However, long term use of PPIs like Prevacid has been linked to increased risks including bone fractures and vitamin B12 deficiency among others. As always it's crucial patients monitor their symptoms closely when starting any new medication regimen.
